agricultural college programs Further, R & D is part of nearly all graduate students studying in the food science, food technology, food processing, and food related programs Lastly, R & D is of vital interest to the public at large and, of course, the ultimate consumer of the fruits of R & D My interest is putting this book together was developed because of necessity as my advisors, teachers, and peers always talked about research and development, but seldom got down to the W’s and H, that is, the why, the when, the where, the what, the who, and the how My advisor and many of my teachers left it up to me and my colleagues to find out who was doing research and development work, what topics were considered worthy of good research in the field, when was the work done, where was the information published, why was a given approach taken, and how were the results being utilized in the industry I was totally appalled by the lack of good resource material and pertinent information Further, I could not fiid good and sound research methods that fit the situation that I was always interested in Therefore, after much consternation and thought, I developed an R & D course of instruction for the graduate students interested in my area of expertise and the thoughts in this book reflect some of the things that I gleaned and shared with these students as we struggled through some 40 years of research in food processing and technology Many of my graduate students have shared with me much information in this book as they have worked in both academia and the food industry They are the ones that made this book come to fruition and they are the ones that suggested I document my thoughts for those who follow, My most sincere thanks to my former students, my many collegeaues, and my many friends in the food industry for their helpful suggestions, criticisms, and inspirations I particularly wish to thank Winston Bash, Ken Beck, Ron Gould, Bill Hildebolt, Jackie Hood, Jim Mavis, Wade Schulte, and Bill Stinson for their critiquing this manuscript and their helpful suggestions My special thanks to Art Judge, II and Randall Gerstmyer for their constructive comments, interest, cooperation and valued assistance Wilbur Gould ABOUT THE AUTHOR Wilbur A Gould was reared on a farm in Northern New Hampshire He received his Batchelor of Science degree from the

Association, Food Technology Consultant to the Snack Food Association, Secretary-Treasurer of The Guard Society, and Consultant to the Food Industries Dr Gould’s philosophy is to tell it as he sees it, be short and get right to the point Chapter RESEARCH AND DEVELOPMENT AND ITS ROLE IN THE FOOD INDUSTRIES "Research is to see what everybody has seen and to think what no body has thought" A S Gyorgyi The food industry is continuously confronted with problems and concerns for its processes and its products Consequently, great opportunities exist for future actions to improve the position of any given firm within the industry through research and development (R & D) Some of the present day major concerns include the following: AUTOMATION - Development of programs, equipment, and application to insure greater on-line efficiencies, better product uniformity, and a reduction of costs BIOTECHNOLOGY & BIOENGINEERING and new processes - New products CONSUMERISM - Dealing with Activists Groups and their wants, the changing eating habits and patterns, Dietary needs, Weight control, etc ENVIRONMENT - Air pollution, solid and liquid wastes FOOD SAFETY - Uses of chemicals for production agriculture, food additives, chemical cleaners, micoorganisms, etc LABELING ISSUES etc - Nutritional and other claims, quality, RESEARCH & DEVELOPMENT GUIDELINES LABOR - Lack of trained and skilled and scientific, costs and benefits including health care and insurance NEW PRODUCTS - Modifications, reformulations and new creations ON-LINE SENSORS AND CONTROLLERS - Identification of product quality during manufacture and for assurance of total quality control PACKAGES AND PACKAGING - Metal, vs glass vs plastic vs composities and product liabilities, insurance, disposal biodegradable, microwaveable, retortable and shelf life PROCESS CHANGES - Aseptics, Can Acid by acidification and refrigeration QUALITY - Its identification, assurance and evaluation ramifications including analytical instrumentation shelf life testing, nutrition, and consumer education RAW MATERIAL COSTS - Urbanization, drought, irrigation, and out of country produced REGULATIONS - Their effect on development of new chemicals and their testing and on food plant operations including marketing of foods RISK/BENEFIT CONCEPTS - Lack of definition and ultimate effect on slowing down of research and marketing of new products and new additives SOLID WASTE DISPOSAL - Organic and inorganic chemical problems, including digestion times and use of mice organisms LABELING - Nutrition, quality/grade identification including consumer education R & D/ROLE IN THE FOOD INDUSTRY Need for Research More money is spent on food today than any other single consumer item Yet, the food industry as a whole spends less money on research and development than any other industry Some industries spend well over 20% of their gross dollar income for research and development while the latest figures indicate that the food industry does not even spend 1% on research and development However, some companies spend a lot of money on research and new product development in their firm Much of it is tied in with quality assurance, production programs, processing changes, marketing practices, etc and not under an R & D Department or funds per se In 1979 NSF published that the continuing rate of return to the gross national product for every dollar invested in R & D was 30 to 50% This was for all industries The return on dollars spent on R & D for the food industry may be higher or lower depending on the product and the firm There is no question that R & D dollars over the long run should make for a good return on the investment if research is properly conducted with the results put into practice If one goes back in history and looks at some of the b t real efforts to solve food problems, one has to take a look at the early 1800’s and Napoleon Bonaparte and his offer of 10,OOO Francs for the development of a method of food preservation Bonaparte could only move his armies as fast as he could move his food kitchens as an army moves on its stomach Today, the highest award by the Institute of Food Technologists is the Nicholas Appert award as Appert was the man that won the 10,OOO Francs for his method of food preservation in 1810, that is, the concept of hermetically sealing food in a container followed by sterilization What is Research? Progress as we know it today would not be possible without research Boss Kettering stated “If you don’t research until you have to, its too late” This statement has been most true and many segments of the industry now realize the importance of a n on-going research and development program Some segments of the industry allocate funds direct for contract or in-house research RESEARCH & DEVELOPMENT GUIDELINES and development Most food firms today realize that the consumer wants new types and styles of different formulated foods Change should be made in some cases in the food industries to make food better Right after World War 11, the U S Government passed the Hatch Act and established a n elaborate system of funding agricultural research Other agencies like the National Science Foundation, also, sponsored research in food and agriculture Presently, private industry funds much of the research in the food areas In addition, due in part to mergers, many companies have established elaborate R & D departments and much of their research inhouse Research in the food areas is a major part of the over 50 Universities around the US where food science and technology programs are offered Faculty and graduate students food research and development work as part of their work load or graduate training Paul Hudson, former Dean of the Graduate School at The Ohio State University once stated that “research is evidence of creative urge and dissemination of information is the human trait of communication” To me this is most relevant and it truly depicts the ideal type researcher Too many people call themselves r e searchers, but they show little creativity and only communicate as little as need be to get by Any one aspiring to be a researcher must be creative and they must want to contribute to man’s knowledge Research in its simplest definition is doing those things that help build or advance existing knowledge Research in the food industries should go beyond this and reduce costs of food production, costs of food preservation and costs of marketing the food supply Research should strive to improve product quality, nutrient retention, and the shelf life of our food supply Research in the food industries should develop new products, processes, and systems of preservation to continue to satisfy consumer wants New products are needed today to satisfy the changing life style needs, to provide food for the large change in ethnic population, and to meet the needs of the changing demographics, that is, teenagers, the YUPPIES, and the increasing number of the elderly The food industry should look at research as their road to the future not just to solve short term goals R & D/ROLE IN THE FOOD INDUSTRY The Scientific Method We learn new fads and ideas by chance, by trial and error, and generalization from experience and by logic, that is, reasoning things out or by using the scientific method of inquiry The scientific method is an orderly system of search for the truth There are six fundamental steps to be followed: 1st step -Identify the problem, establish the objectives or develop the hypothesis, that is, the ‘‘why” 2nd step -Find out “what” has been done to-date, that is, start with a library search of the literature, patents, etc 3rd step -Develop a procedure or establish the approach to solve the problem, that is, the “how” to it 4th step Collect the data or gather the fads, that is, work the plan 5th step -Interpret the data to find the solution to the objectives or test the hypothesis 6th step -Develop conclusions, make recommendations, and summarize your efforts Research is accomplished by people with inquisitive minds seeking the truth and new ideas and concepts, hopefully, to improve the food industry and all foods for mankind Research may be very basic, that is, understanding the fundamentals of change or the reasons why things are different from one another This in the past was accomplished by Federal and State agencies and many non-profit educational and institutional research organizations Research may be very practical or applied, that is, determining the best usage for any given tomato variety Generally, basic research in the food industry is left to the food scientist whether he or she be in academia as a candidate for the Ph D degree or a staff member in an R&D laboratory in the food industry This kind of research is needed to build a base from which to make application by the food technologist to the food industries The technologist applies this basic research to solve industry problems RESEARCH 8z DEVELOPMENT GUIDELINES Product or process development research can be both basic and applied depending on what is being attempted Development of a new food additive would be basic research while the application of an additive to given food items would be applied research Many researchers both types of research and they not distinguish between either term Frankly, I think too much has been written and made over about these terms in the literature and I think its high time we describe them both as those things that we diligently to search for the truth or new knowledge to solve the problems of the food industries From a researchers standpoint, problems are opportunities and that’s the way I look at food researchopportunities to help the individual food firm help itself to stay ahead of the competition Some Research Objectives The following are some broad areas that may be a part of the objectives or reasons for establishing and R & D program or department To solve existing problems and nuisances in connection with materials, methods (processes), machines, finished products, services (manpower) and environment and to anticipate and prevent such troubles from occurring in the future To reduce costs involved in the use of materials, processes, products, and services To improve the quality of existing materials, products, processes and services To develop new products, new line extensions, or new uses for exisiting materials, products, processes, and servcies To develop suitable substitutes for existing materials, products, processes, and services To develop uses for waste materials thus, creating new byproducts To keep the firm abreast of scientific and technological knowledge in areas of vested corporate interests RESEARCH & DEVELOPMENT GUIDELINES 158 Table 13
