ABSTRACT

In the beginning there was Appert who in 1810 introduced the Canning (actually sawed off Champagne bottles) to the word. Fifty-five years later (1865) Louis Pasteur introduced the science of microbiology and showed that heating beers “pasteurization “ sealed vessels extended shelf life. At that time refrigeration was accomplished through nature, i.e. dark cool caves or underground (rooms facilitated with ice cut from lakes during the winter). At about the same time Karl von Linden in Germany built the first mechanical device that provided industrial chilling of beer vats so they could produce lager beer in the Spring and Summer. An then in 1888 Samuel Cate Prescott at MIT working with the son of William Underwood showed that one could eliminate swollen cans by heating at higher temperatures and longer times. Drying solid foods on the small scale (village) was done by the sun or a fire below and wind. It has been traced back to 12,000 BC in the Middle East. Again in the 1870’s, the 1st patent for drying liquids was awarded to Samuel Percy. The concept of freeze-drying was invented in 1906 by d’Arsonval in Paris. Also going back to historic time we had the development of milling/fermentation/baking. It is thrilling to see the mill and oven in Pompei. However it took until 1922 for a commercial unit to come in use in the food industry. So now we come to 1916 - 100 years ago. At that time we have the foundations of canning, refrigeration, drying, fermentation and the baking industry. In 1929 Prescott and Proctor of MIT in conjunction with faculty from the Univ. of Massachusetts help formed the IFT with the idea of having interactions between academic researchers, the food industry and the government, especially those at the US Army Quartermaster Corps Labs in Chicago who worked on food preservation, military clothing and food service (later moved to Natick, MA). From this arose some of the first Engineers and the use of mathematical modeling using unit operations from the Chemical Engineering field. An example was the work of C. Olin Ball at the American Can Co. as well as Charles Stumbo at the Univ. of Massachusetts and Erv Pflug at Michigan State for some of the numerous pioneers in heat transfer models for canning in the 1940s through the 1960s. This work was done with use of slide rulers or mechanical hand cranked calculators. A revolution began in the 1970’s with master computers and punch cards that had a program to do the calculations. In the 100-year period we went from batch pasteurization of liquids like milk at low temperature and long time to continuous systems using a tube in tube heat exchanger or a plate and frame system. This leads us to understand the vast difference in liquid flow as a function of shear rate. Stanley Charm who was the 1st academic (MIT) to write a book on Food Engineering worked in this area using only an ancient Brookfield and the crank calculator. We also learned the need for blanching of fruits and vegetables before canning. The other major breakthroughs were the continuous hydrostatic sterilizer, and AlpaC multiple system sterilizer and the microwave oven initially for food service. Another outcome of the military work was the development of the retort pouch, a project Marcus Karel had from the Natick labs. This then leads to non-thermal processing such as irradiation (Goldblith at MIT in 1958, pulsed electric fields, cold plasma, and pulsed light, and the most developed one, i.e. ultra High Pressure pasteurization. And then there was the going back to low temperature long time pasteurization of in the shell eggs (Davidson) and oysters. This was done to prevent protein denaturation yet kill the pathogens. During this same time we had the development of the drying industry which was revolutionized by the invention of fluid bed driers, spray dryers, roller (drum) dryers and finally the commercial freeze-dryer pioneered by MIT. Another first at MIT was understanding the oxygen, CO2 and water vapor transmission properties of different plastic films on food shelf life, the early work of Lockhart, Proctor and Karel. This was followed by the fine-tuning done by Saguy, Mizrahi, Karel and myself in the 1970s using tower computers. These findings have a broad use in most food processes. The Cereal Industry also had a major new technology beginning with the work of Cheftel in 1976 in France on an extruder, a technology borrowed from the Chemical Engineering Plastics field and now a key process for many food categories. A major turning point in the fields of food microbiology, food shelf life and food texture was the development of the physical-chemical application of water activity that came out of many food science labs from around the world. Karel and his students like me, Roos, Saguy and Aguilera, all participants in this meeting, were part of the pioneers in this field. It is interesting that the food/science/food engineering field was the 1st to see the practicality of a simple thermodynamic equation. It led to the development of a whole new food category concept, i.e. Intermediate Moisture Foods. The Burgess 1965 patent was one of the first for IMF, in this case a dog food. This concept is now used in the pharmaceutical, wood and paperboard industries. The second paradigm shift was the transfer of a principle from polymer science/technology in 1998, i.e. the concept of glass transition that better helps the understanding of food texture changes during processing and storage. This was pioneered by Slade (PhD Chemist) and Levine (PhD Polymer Science) at General Foods and Felix Franks who then was the head of the food physics lab at Unilever. Thus we have seen a field coming from the cook and look home kitchen approach to a field that has found technologies to create high quality, safe foods for the consumer. One should note that part of the Thrust into new technologies was due to environmental concerns (more energy efficient, reduced waste), and equipment designs to ensure safety as mandated by the food laws in the country. We as Food Engineers have had a major role in this revolution; though the 100 years may be evolution - I think not.

Food engineering (FE) has suffered from an identity problem vis-a-vis the traditional engineering sciences. FE is often regarded as food technology, something which has been onerous in academic terms but been beneficial for people in terms of an abundant and steady supply of processed foods. Here are 10 things in food process engineering that are changing our lives and should make us be proud of:

  1. Improved processes and technologies at the production line leading to the abundance and variety of foods worldwide.
  2.  Advances in non-invasive technologies for even better food quality and food safety.
  3. Advances in process modeling and simulation.
  4. Efficient use of water and energy during processing.
  5. Development of a food materials science (appreciating the engineering inside our foods).
  6. Emergence of the brain-mouth-cell axis (understanding food processing and engineering inside our bodies).
  7. Engineering sustainable foods for the future (the new egg and meat from plants).
  8. Food product design and engineering for target populations (the obese and the elderly, diabetics, and Major Tom).
  9. Development of new interfaces between engineering and other sciences and disciplines (pharma, neurobiology, nutrigenomics, gastronomy, etc.).
  10. What is going on in food nanotechnology?

ABSTRACT

Food Engineering (FE) profession is at a crossroads caused mainly by diminishing financial support, reduced critical mass and academic positions, and declining attractiveness to young students. Innovation plays a cardinal role in meeting mounting challenges and opportunities offered by the unabated accelerated progress in science and technology. It is also essential in the creation of new jobs, improving standards of living and contributing to new processes, services, business models and social needs. “Innovate or die” mantra has evolved to open innovation (OI), partnerships, ecosystem, disruptive and agile, essential in achieving competitive advantages in businesses and should be also in academia. Some OI vital ingredients are: four-helix innovation ecosystem (industry-academia-government-private sector) collaboration, social responsibility, and a new mindset. Academia’s special role in meeting emerging responsibilities, and offering Food Engineers of the future new skills and horizon is leading a ‘startup university’ mentality and pursuing innovative solutions. Enginomics (engineering + omics) is a FE frontier that combines multidisciplinary and holistic approach for amalgamating food processing and the whole human digestion system (e.g., gastric unit operations, bioavailability, accessibility), health and wellness (e.g., medicine, brain, biome, pro-/prebiotics, nanotechnology, biotechnology) and nutrition (e.g., personalization, prevention, obesity). Combining OI principles with Enginomics furnishes Food Engineers a significant role in spearheading the paradigm shifts required to make this a reality.

ABSTRACT

The Food industry is facing an increasingly complex global environment. Major changes have occurred in the last decade. These include demographic changes shifting consumer preferences for less processed foods, an expanding middle class in developing markets, greater environmental consciousness, digital growth, diverse retail environments, regulatory changes, and new competitive dynamics as a result of the democratization of innovation and reduced barriers to entry. Moreover, the pace of change continues to accelerate.

Cost control programs and reshaping portfolios for growth are key themes across food companies as they respond to these sweeping changes. Science and technology are critical enablers in driving superior cost performance, innovation and scalable growth. Novel technologies that are grounded in consumer needs deliver superior results. Greater success is achieved by augmenting internal company technical expertise with advantaged external networks and partnerships. This approach is integral to general Mills' success.

Future opportunities for the industry will include consumer centric technology development at the interface of Food Science, Chemical Engineering. Materials Science, Biology and Medicine.

ABSTRACT

Conventional approaches to process foods have proven to offer very safe products but, in some cases, the quality of the final product is significantly lower to the original one and the impact on the environment might be of great concern. Over-processing implies safety, but at a high cost in terms of nutrients and other quality attributes. Nonthermal processing of foods has emerged as a viable alternative to those conventional processing techniques by offering safe products of excellent “total quality” at very reasonable cost, and in general, they are environmental friendly, and they could be listed as “green technologies” with great confidence. It is the case; these nonthermal technologies could be used in combination among themselves or with other preservation approaches seeking synergistic effects in order to have shorter processes and very good quality food products.

This presentation analyzes some of the most relevant nonthermal technologies which have been recently implemented by the food industry, and when and how others will be in the near future. Special attention will be given to the impact they are making in environmental, health and socioeconomic issues, as well as emphasizing how they help to circumvent new rules and regulations while facilitating more efficient marketing strategies and distribution systems.

ABSTRACT

Food Engineering in industry will focus on the role of Food Engineering and the attributes of a successful Food Engineer in industry. To illustrate the aspects of Food Engineering that are important in solving breakthrough opportunities, an example of new product and process launched by Frito-Lay (a division of PepsiCo) viz. “Sunchips” will be used as a case study. The challenges in introducing multi grain ingredients, controlling oil uptake to deliver a 25% reduction legal claim in fat, and high consumer liking was successfully delivered utilizing many of the principles of Food Engineering including mixing, rheology, extrusion, heat and mass transfer and process controls. As a resultant of the case study the presentation will address the skills in Food Engineering that are needed for solving future industry opportunities, and other important attributes of an engineer that are required for success.

Dr. Sudhir Sastry is Professor in the Department of Food, Agricultural and Biological Engineering at The Ohio State University.

This has been followed up by a project to adapt these findings to heatable packages for commercial applications. Dr. Sastry’s inventions include a new, environmentally friendly produce peeling process, and a pH sensor that can be operated under extreme pressures.

ABSTRACT

For Food Engineering in Academia, we focus on educational programs and offerings largely within the United States. Food Engineering faculty are typically distributed between departments of Biological/Agricultural or similarly named programs, or Food Science. Educational objectives in each case are different – students in engineering programs must satisfy ABET accreditation criteria, while those in Food Science programs go through the IFT Higher Education Review Board. Objectives and challenges are different in each case. Opportunities are significant, as the Food industry continues to need engineering input, and many Food Engineering skills may be useful in problems relating to water and waste in the 21st century. A few case studies of educational efforts will be presented, including design problems and examinations that involved industry participation.

ABSTRACT

Many food products are sold in powdered form. The properties of these powders strongly depend on the design of the particles they are composed off. Such particle design comprises structuring of single particles on the supra-molecular and micro scale. On the supramolecular scale the degree of order in monomolecular particle domains (degree of crystallinity) has a significant impact on the physicochemical properties of the solids. This has been already demonstrated by Prof. Karel and his co-workers many years ago. During the current presentation it will be discussed how the degree of crystallinity in powders can be modulated via formulation and drying technology. In particle design one also has to consider molecular segregation during particle formation because of its significant impact on the material properties. The micro-scale covers inclusion of gas bubbles or lipid droplets into glassy amorphous matrices. Application of the principles of polymer chemistry to food matrices enables to generate very dense glassy structures capable of retaining significant gas amounts for up to one year. Furthermore material science helps to better understand adhesion forces between single particles and to agglomerate them to the desired particle architecture. Finally innovative gelling and emulsification technologies provide tools to design particles with totally new properties such as Aerogel, protein micro gel or solid multiple emulsion particles. In all these technologies food material science plays a very important role. Especially the application of the principles of polymer physics to food matrices as it was developed by Prof. Karel and his co-works decades ago still remains one of the most important approaches for targeted particle design in the food industry.

ABSTRACT

With rising prevalence of chronic diseases (e.g. obesity, diabetes and IBD), soaring life expectancy and need for sustainability, there is an evident need for rational and effective design and utilization of foods to meet consumer preferences, acceptance and needs (PAN profile).

Picture

This lecture will present examples of studies applying an engineering and holistic -omics approach, termed enginomics or foodomics, to the challenge of understanding the complex triad of processing-structure-digestibility. First, the use of V-amylose, naturally found in starch, will be shown to be useful for the nano-encapsulation and enhancement of the bioavailability of lipophilic bioactives. Second, the combined use of in vitro digestion models, proteomics and bioinformatic tools will be discussed in the prospect of the differential digestive fate of proteins in infants, adults and the elderly. Overall, these evidence-based studies will expose attendees to novel concepts and ideas merging an advanced approach to product engineering coupled with state of the art –omics technologies. These will facilitate the future application of reverse engineering to the development of natural food ingredients and products tailored to meet the needs of specific human populations.

Food Material Science Driving Product Innovations

Dr. Laurent Forny

Dr. Laurent Forny holds a degree in Chemical Engineering and a PhD in Physical Chemistry from the University of Technology Compiègne (France). In 2008, he joined the Nestlé Research Center, Lausanne, Switzerland. Here, his research activities examine the critical role of moisture in food processing and how to control the Functionality of food products (e.g. stability, texture, targeted delivery, flavours). He has also been exploring new scientific areas, examining crystalline ingredients and the reconstitution of dehydrated powders. Laurent collaborates with several universities and recently conducted a project in the Agency for Science, Technology and Research (A*Star) in Singapore. He has published 14 articles in peer-reviewed journals, and delivered more than 30 oral communications in international congresses.

ABSTRACT

Materials Science at Nestlé has developed quite considerably since the 1990’s. Our initial effort focused primarily on harnessing and expanding academic work done in the field of lactose crystallisation and the processing of milk powders. Yet, the knowledge gained opened up several new and innovative avenues of research, which led to the development of diverse products such as a foam booster for cappuccino and more recently, the launch of a proprietary machine which prepares single-serve portions of infant formula from sealed capsules. Our most important objective is to support Nestlé’s strategic commitments to Nutrition, Health and Wellness. For instance in order to reduce the level of saturated fatty acid which limits the interaction of complex products with surrounding relative humidity, our group revealed the importance of previously unrecognized mechanisms such as Mutual Deliquescence or “Sintescence” (neologism to describe unique interactions between amorphous and crystalline ingredients). And, to reduce sodium uptake, we have explored the entire scope of engineering sodium chloride. A key factor in all our work has been our internal Materials Science Learning Workshops which were created more than 15 years ago, with the support of renowned professors from academia, including Prof. Marcus Karel. Since their instigation, these workshops have provided an ideal platform for sharing the most advanced knowledge in the field, and have led to the development of innovative concepts across Nestlé R&D.

Virtualization in Food Engineering: Challenges and Opportunities

Professor Francesco Marra

Professor Francesco Marra has Ph.D. in Chemical Engineering, he is assistant professor at School of Chemical and Food Engineering of University of Salerno (Italy). His research focuses on virtualization of food processes and modeling of transport phenomena in multi-physics context and engineering of innovative prototypes for food processing. He has authored over 70 scientific papers published in refereed international journals, in books and in international conferences. Recently, he served as Guest Editor of a Special Issue of the Journal of Food Engineering on ”Virtualization of Processes in Food Engineering”, Professor Marra is member of IFT and of EHEDG, and he recently he joined ISFE and ISEKI Food Association.

ABSTRACT

A list of activities (that could be purely intellectual and/or mathematical - computational) such as data modeling, statistical analysis, fundamental modeling, dynamic simulation and optimization, but also computer aided design and engineering, can be included in a unique, wider scheme called virtualization of processes. Virtualization of processes is gaining interest in Food Engineering, though the Food industry is still lagging to utilize the wide spectrum of potential opportunities offered by virtualization as an engineering design tool. The complexity of food systems and food processes themselves together with the difficulty to mathematically address the phenomena taking place at different levels of scale during food processing often reduced the virtual approach to a number of intellectual/computational activities without a clear, practical, immediate use of virtual tools connected to daily-life operations in the food world. New concepts such us smart-technologies, internet of things, custom-digital life-style, can open a number of opportunities in the field of virtualization of processes in Food Engineering. In this presentation, some of these opportunities are discussed together with the challenges to be addressed in order to make virtualization a main cornerstone in the Food Engineering domain.

Kearney Scholar 2011 & 2012 at the Falling Walls conferences. He also served as lecturer, teacher, reviewer and supervisor with several universities and organizations.

ABSTRACT 

Sustainable food processing as key driver of the Bioeconomy covers process-product-operation interactions, where selected examples of innovative thermal, electro-magnetic, mechanical and combined processes will be introduced hereafter. Modular thermal micro process engineering was effectively applied to improve upscaling of microbial inactivation processes. Electro-magnetic based pulsed electrical field processing enables an efficient use of biomass and energy within several value chains. Consequently, PEF was successfully implemented into the potato and fruit juice industry. During mechanical high pressure processing in batch, focused investigations on the property changes within pure water and more complex systems, such as microorganisms, enabled a detailed understanding of the respective process-product-operation interactions. After studying spore inactivation in very detail, classical high pressure preservation could be optimized through combined thermal and mechanical processes such as high pressure thermal sterilisation as well as continuous ultra-high pressure processing up to 400 MPa as innovative multi hurdle technologies for gentle sterilisation of healthy and high quality food. Advanced approaches relying on innovative raw materials from algae or insects and their connected biorefinery concepts could even increase the impact of sustainable food processing. Holistic life cycle sustainability assessment, aligned with the introduced process innovations, can evaluate the suggested solutions on a multi parameter base, in terms of improved food production sustainability.

ABSTRACT

The discipline of Food Engineering is constantly evolving. Triggered by both advances in Science and changes in the funding environment, recent years have seen an interesting expansion of Food Engineering to incorporate biological and chemistry based approaches. This presentation will offer a few insights and examples of how Food Engineering principles are being used to improve the safety of the food supply. The integration of physics and biology has allowed Food Engineers to develop quantitative models to predict the response of foodborne bacteria to different stresses, and design efficient, yet quality preserving food safety interventions. By understanding and integrating phenomena that take place at the nanoscale, Food Engineers are making significant contributions towards understanding and quantifying the interaction forces between foodborne pathogens and food contact materials, resulting in a new generation of bacteria repellant or antibacterial surfaces.

Status of Food Engineering Programmes

Professor Keshavan Niranjan

Professor Keshavan Niranjan or Niranjan - as he is better known - is the Professor of Food Bioprocessing at the University of Reading in UK. He has a strong research portfolio with publications in a number of areas including bubble containing foods, high pressure processing, and development of compostable packaging; He is currently the lead investigator in research projects funded by leading governmental agencies as well as multi-national companies. He is an editor of the Journal of Food Engineering, a Fellow of the Institute of Food Science and Technology, and the immediate Past Chair of the International Society of Food Engineering.

ABSTRACT

Training, Research and Enterprise are the three essential pillars of any academic discipline operating within Higher Education. The success and sustainability of the discipline depends on having a healthy portfolio of all three activities. Food Engineering has operated within the higher education system for well over seven decades. Although Food Engineering has healthy research and enterprise portfolios in most parts of the world, its training at undergraduate and graduate levels leaves a lot to be desired. This presentation gives an overview of food engineering training in different parts of the world and finds that there are very few countries in the world which have professionally accredited Food Engineering courses operating at an undergraduate level. More importantly, there are very few, if at all any, full-fledged undergraduate programmes being offered in countries such as USA, Canada, and countries in Northern and Western Europe – which have traditionally been the torch bearers of training in engineering disciplines, and provided leadership to the rest of the world in training engineers. This presentation argues that the time has come for Food Engineering to assert itself as a mature and stand-alone branch of engineering, alongside other traditional branches of engineering such as mechanical, electrical, civil and chemical. Food Engineering will only find its rightful place if we are able to introduce strong undergraduate programmes - especially in North America and Europe - which will stimulate and attract bright young minds into the discipline. This presentation will also introduce a new framework for developing undergraduate programmes that is fit for purpose in the 21st century. The presentation also argues that the research funding policy pursued in North America and Europe – where engineering is seen to be too close to business and therefore not so deserving of government support - is a grave threat to Food Engineering research, and will inevitably result in research groups themselves becoming unsustainable. The introduction of successful undergraduate programmes in Food Engineering can support research in the area and vice versa, and this is the best way to ensure that the discipline has a sustainable future.

Self-healing Antimicrobial Polymer Coating with Efficacy Against Escherichia coli O157:H7 in the Presence of Organic Matter

Dr. Luis J. Bastarrachea

Dr. Luis J. Bastarrachea received B.Sc. and M.Sc. degrees in Food Engineering from Instituto Tecnólogico y de Estudios Superiores de Monterrey (Mexico) and Washington State University Pullman, respectively. He currently works as a postdoctoral scholar in the department of Nutrition and Food Science of the University of Maryland College Park. His postdoctoral and Ph.D. research in food science at the University of Massachusetts Amherst involved the development of antimicrobial polymeric materials with rechargeable and self-healing properties. He currently studies the use of non-thermal food processing technologies like ultrasound and photosensitization to improve the quality and safety of food.

ABSTRACT

A method to prepare an antimicrobial coating which dual biocidal character retains efficacy against Escherichia coli O157:H7 in the presence of organic matter is reported. A coating composed of branched polyethyleneimine (PEI) and styrene maleic anhydride copolymer (SMA) was applied onto maleic anhydride functionalized polypropylene. The chemistry of the polymer coating was tuned to impart hydrophobicity, intrinsic antimicrobial character (>99.9% reduction) from the cationic amine groups, and enhanced antimicrobial character (>99.99% reduction) after chlorination of N-halamine groups. Antimicrobial effectiveness was also confirmed under conditions of increasing concentrations of organic matter. At organic loads of up to 500 ppm horse serum, coatings exhibited full retention of antimicrobial character when chlorinated (> 99.99% reduction) and significant retention of antimicrobial character in its intrinsic form (~ 99.0% – 99.9% reduction). At higher organic loads (5,000 ppm horse serum), the coating exhibited a similar biocidal behavior in its N-halamine and cationic forms, providing ~ 99.4% – 99.7% reduction. Even at 50,000 ppm of horse serum, the coating provided ~ 90% reduction as prepared, and ~ 75% – 80% reduction in its N-halamine form. Coating also exhibited self-healing properties after exposure to acid and alkaline solutions and restoration by heat, as confirmed through infrared and X-Ray photoelectron spectroscopies.

ABSTRACT

Global probiotics market steadily expands every year due to the prominent importance of probiotics as health-promoting reagents, diarrhea treatment pharmaceutics, green preservatives in feedstuff, and traditional dairy starter cultures. To meet the increasing needs, a mass-manufacture approach capable of producing active dry probiotics with high viability retention, stable properties, and long shelf life is desired. While spray drying is a rapid powder production technique for heat-sensitive materials, great challenge lies with the survival of probiotic cells during drying. Various approaches have been developed to enhance the survival ratio, of which the selection of protective carrier and optimization of drying kinetics would be of paramount importance as they directly affect the inactivation rate of probiotic cells during drying. Despite the large number of new studies reported each year, some fundamental questions are yet to be answered. For example, a carrier material may show opposite effects in protecting cell viability under different drying schemes; what shall be the correlation between drying kinetics and cells inactivation for each carrier? Reconstituted skim milk shows the most reputed protective effect amongst reported carriers, but the protective mechanism is still being discussed over the literature, making the construction of more powerful protectant a further aim. At the cellular level, cell death should be caused by the denaturation of one or more cellular structures; is there a critical structure that is the main cause? In this presentation, we describe Single Droplet Drying (SDD) studies to establish quantitative correlations between cell inactivation and drying kinetics upon different drying conditions and carrier materials, and to further the investigation to protective mechanisms of carrier materials on both cell viability and cellular structures.

Manipulating the Solid State Structure of Thiamine: From Deliquescent Crystal to Liquid Crystal to Amorphous State

Professor Lisa J. Mauer

Dr. Lisa Mauer is a professor of food science and the director of the Center for Food Safety Engineering at Purdue University. She completed her Ph.D. in food science at the Universtiy of Minnesota, working jointly with Drs. T. Labuza and D. Smith. Dr. Mauer’s research program focuses on improving food stability, quality, and safety. A significant aspect of her research is the manipulation and characterization of water-solid interactions and food ingredient architecture, for which she received the 2014 IFT Marcel Loncin Research Prize, Purdue Agricultural Research Award, and Faculty Scholar recognitions. She is also a Fellow of the Purdue University Teaching Academy.

ABSTRACT

Although both synthetic thiamine forms (HCl and mononitrate) are deliquescent crystals, upon their introduction into complex food formulations and exposure to food processing conditions they may convert to the amorphous form. The objectives of this study were to: (1) prepare amorphous forms of thiamine mononitrate and HCl using solid dispersion and lyophilization techniques; and (2) investigate and compare the role of polymers (accounting for hygroscopicity, glass transition temperature, and noncovalent intermolecular interactions) on inhibiting the crystallization of thiamine mononitrate and HCl during storage in controlled temperature and RH environments. Neither thiamine mononitrate nor HCl could be made amorphous by lyophilization in the absence of a polymer, but it was possible to amorphize thiamine in the presence of numerous polymers. More polymer was needed to amorphize thiamine mononitrate than thiamine HCl. Interestingly, a new solid state of thiamine mononitrate, a liquid crystal, was produced at polymer ratios below those needed to amorphize the vitamin. Studies are ongoing to document the physical and chemical stability of the thiamine mononitrate and HCl dispersions; however, it is clear that the different salt forms of thiamine have distinct physicochemical properties in solid dispersions and the physical stability of the amorphous vitamin is more dependent on intermolecular interactions between the vitamin and polymer than on the Tg or hygroscopicity of the polymers.

Reaction Pathways Activated during the Elaboration of Food with a Focus on Baking of Cereal Products

Dr. Catherine Bonazzi

Dr. Catherine Bonazzi is Reseach Director at the French National Institute for Agricultural Research (INRA), working on food engineering, and Deputy Head of the joint research unit for Food and Process Engineering at AgroParisTech. She completed PhD in Process Engineering at the National Institute of Agronomy of Paris-Grignon, in cooperation with the group MIKO, focusing on freeze-drying of vegetables. Her expertise is based on comprehensive knowledge of the mechanisms carried out during processing of food, mainly drying and cooking, and their impact on the quality of products. She heads a research team working on dynamic characterization and modelling of the impact of thermal and mechanical processes on the (bio-)chemical reactions involved in the building of nutritional and organoleptic properties of foods.

ABSTRACT

There is an increasing demand from the Food industry for complex products with controlled nutritional and sensorial properties (vitamins, antioxidants or flavor compounds contents). Many of them result from chemical reactions induced in food by the technological treatments. The conception of foods and the reappraisal of the products and processes require strategies allowing the appearance and the protection of valuable compounds to be controlled. The reactions in food systems are described as complex networks of chemical reactions, but only a small part of all the molecules can be experimentally observed. A major stake of our work is to propose simplified identifiable reaction pathways which can give a reliable representation of the complex reaction system occurring during baking of cereal products, taking into account the experimental constraints and the available information. A limited number of observable chemical markers were selected according to their ability to point out different advancement steps of the reactions (Maillard reaction, caramelization, lipid oxidation). We built an instrumented pilot oven equipped with a dynamic online measurement of volatile compounds that made it possible to obtain synchronous physical and chemical kinetic experimental data. We also developed a model product mimetic of sponge cake for a systematic and rational study of reactions, mastered by the addition of aptly chosen reactants. The representation of the reaction system as a stoichio-kinetic model, combined with mass balance and enthalpy equations, will provide a quantified vision usable to conduct manufacturing, but also to capitalize on the knowledge acquired in food chemistry regarding the reaction schemes. .

ABSTRACT

Over the past two decades, the food manufacturers gained experience in various industrial application of nonthermal-thermal based advanced technological concepts particularly high pressure based technologies. They satisfy health conscious consumer demand for fresh tasting foods with minimal or no chemical preservatives. Though originally introduced as a food safety technology, the creative applications of high pressure (including the opportunity to preserve foods with cleaner ingredient label, potential to reduce salt and fat in the formulated products, nutrient infusion) continue to sustain the industrial interest. This presentation will briefly summarize the research carried out at The Ohio State University, Food Safety Engineering Laboratory. By creatively controlling the intensity of pressure treatment with advanced thermal methods (such as ohmic heating) or other nonthermal methods will enable the preservation of extended shelf-life (ESL), shelf-stable foods. High pressure homogenization (HPH) is a pressure based continuous flow process that can be used for preserving novel formulations of beverage products without destroying health promoting bioactive compounds. Role of Food Engineering discipline in the development of next generation of nonthermal based technologies for industrial use is highlighted.
