Book Description
Food processing by humans goes a long way back in time, e.g., heat for cooking was used 1.9 million years ago. However, meal preparation now seems to be moving out of the home kitchen, and preprocessed or processed/convenience food products are becoming a larger part of the daily diet. In addition, consumers are progressively focusing on the impact of food on their health, and they demand foods that have a high nutritional quality and an aroma and natural flavor that are similar to freshly-made products. Therefore, nutritional quality is concurrent with food safety, and sensory perception is becoming an increasingly important factor in food choices. The human digestive tract disintegrates food to allow the nutrients to be released and made available to the body. However, nutrients can undergo unwanted degradation upon processing and subsequent storage, negatively influencing the physiological effects. Different processing techniques will result in different food structures, thereby also affecting bioaccessibility and nutritional value. Hence, food scientists and industry have an increased interest in both conventional and innovative processing methods that can provide good-quality products with high nutritional value and stable shelf life. This Special Issue aims to shed some light on the latest knowledge about and developments within the effects of food processing and storage on changes of biochemical and nutritional compounds. Both original research articles and reviews are included in this book.

Book Description
Chemical changes that occur in foods during processing and storage are manifold and might be both desirable and undesirable in nature. While many of the processes are carried out intentionally, there are also certain unwanted changes that naturally occur in food and might have to be controlled. Therefore, efforts are made to devise processing technologies in which desirable attributes of foods are retained and their deleterious ef fects are minimized. While proteins, lipids and carbohydrates are the main nutrients of food that are affected by processing, it is their interaction with one another, as well as in volvement oflow-molecular-weight constituents that affects their flavor, color and overall acceptability. Thus, generation of aroma via thermal processing and bioconversion is of utmost importance in food preparation. Furthermore, processing operations must be opti mized in order to eliminate or reduce the content of antinutrients that are present in foods and retain their bioactive components. Therefore, while novel processing technologies such as freezing, irradiation, microwaving, high pressure treatment and fermentation might be employed, control process conditions in a manner that both the desirable sensory attributes and wholesomeness of foods are safeguarded is essential. Obviously, method ologies should also be established to quantitate the changes that occur in foods as a result of processing. This volume was developed from contributions provided by a group of internation ally-recognized lead scientists.

Book Description
A variety of processing methods are used to make foods edible; to pennit storage; to alter texture and flavor; to sterilize and pasteurize food; and to destroy microorganisms and other toxins. These methods include baking, broiling, cooking, freezing, frying, and roasting. Many such efforts have both beneficial and harmful effects. It is a paradox of nature that the processing of foods can improve nutrition, quality, safety, and taste, and yet occasionally lead to the formation of anti-nutritional and toxic compounds. These multifaceted consequences of food processing arise from molecular interactions among nutrients with each other and with other food ingredients. Since beneficial and adverse effects of food processing are of increasing importance to food science, nutrition, and human health, and since many of the compounds formed have been shown to be potent carcinogens and growth inhibitors in animals, I organized a symposium broadly concerned with the nutritional and toxicological consequences of food processing. The symposium was sponsored by the American Institute of Nutrition (AIN) -Federation of American Societies for Experimental Biology (FASEB) for its annual meeting in Washington, D.C., April 1-5, 1990. Invited speakers were asked to develop at least one of the following topics: 1. Nutrient-nonnutrient interactions between amino acids, proteins, carbohydrates, lipids, minerals, vitamins, tannins, fiber, natural toxicants, etc. 2. Effects of radiation. 3. Thermally induced formation of dietary mutagens, antimutagens, carcinogens, anticarcinogens, antioxidants, and growth inhibitors. 4. Effects of pH on nutritional value and safety.

Book Description
Biochemistry of Foods attempts to emphasize the importance of biochemistry in the rapidly developing field of food science, and to provide a deeper understanding of those chemical changes occurring in foods. The development of acceptable fruits and vegetables on postharvest storage is dependent on critical biochemical transformations taking place within the plant organ. The chapters discuss how meat and fish similarly undergo postmortem chemical changes which affect their consumer acceptability. In addition to natural changes, those induced by processing or mechanical injury affect the quality of foods. Such changes can be controlled through an understanding of the chemical reactions involved, for instance, in enzymic and nonenzymic browning. Increased sophistication in food production has resulted in the widespread use of enzymes in food-processing operations. Some of the more important enzymes are discussed, with an emphasis on their role in the food industry. The final chapter is concerned with the biodeterioration of foods. The various microorganisms involved in the degradation of proteins, carbohydrates, oils, and fats are discussed, with special reference to the individual biochemical reactions responsible for food deterioration.

Book Description
Food Storage Stability addresses one of the foremost problems faced by food processors - how to stabilize food once it is harvested. Using a holistic approach, the book discusses the changes responsible for food quality deterioration and considers strategies for minimizing or eliminating these degradative changes. Topics include: consumer perceptions and preferences, cellular changes, conversion of major constituents to more stable products, the effect of color and texture, packaging issues, and practical strategies for storing foods frozen, chilled, or at ambient temperature. Food Storage Stability is the only treatment of this subject that covers the diverse factors that influence quality retention in foods and integrates basic concepts in storage stability with practical applications. Food scientists and technologists concerned with changes in food quality are interested in ensuring that safe and appealing food products reach consumers - this is the book that will assist them with that important goal.

Book Description
This volume results from the Eighth Basic Symposium held by the Institute of Food Technologists in Anaheim, California on June 8-9, 1984. The theme of the symposium was "Chemical Changes in Food during Processing." The speakers included a mix of individuals from academic institu tions, governmental agencies, and the food industry. Twenty speakers discussed topics ranging from the basic chemistry relating to food constituents to the more applied aspects of chemical changes in food components during food processing. It was the intent of the organizers to bring together a group of speakers who could address the chemistry of changes in food compo nents during processing from a mechanistic point of view. As a con sequence, the proceedings of this symposium emphasize the basic chemistry of changes in food constituents from a generic perspective which is intended to provide the reader with a background to address more specific problems that may arise.
