Principles Of Enzymology For The Food Sciences

This second edition explains the fundamentals of enzymology and describes the role of enzymes in food, agricultural and health sciences. Among other topics, it provides new methods for protein determination and purification; examines the novel concept of hysteresis; and furnishes new information on proteases, oxidases, polyphenol oxidases, lipoxygenases and the enzymology of biotechnology.

The second edition of this successful book highlights thewidespread use of enzymes in food processing improvement andinnovation, explaining how they bring advantages. The properties ofdifferent enzymes are linked to the physical and biochemical eventsthat they influence in food materials and products, while these inturn are related to the key organoleptic, sensory and shelf lifequalities of foods. Fully updated to reflect advances made in the field over recentyears, new chapters in the second edition look at the use ofenzymes in the reduction of acrylamide, in fish processing and innon-bread cereal applications such as flour confectionery. Geneticmodification of source organisms (GMO) has been used to improveyields of purer enzymes for some time now but the newer technologyof protein engineering (PE) of enzymes has the potential to producepurer, more targeted products without unwanted side activities, anda chapter is also included on this important new topic. Authorshave been selected not only for their practical working knowledgeof enzymes but also for their infectious enthusiasm for thesubject. The book is aimed at food scientists and technologists,ingredients suppliers, geneticists, analytical chemists and qualityassurance personnel.

Abstract: Fundamental reference information on enzymes and their functions in relation to food characteristcs is provided. Introductory material includes the basics of enzymology, commercial enzyme production, control of enzymes, and management of their action. Enzyme action is then reviewed in association with major food-characteristic areas: food color quality; food flavor quality, food textural quality; physical transformations of food (wines, juices, malting, brewing, and making bread and cheese); and food quality control. An extensive bibliographic listing is provided. A detailed tabulation of enzymes, their substratesand use, is also included. (wz).

The biochemistry of food is the foundation on which the research and development advances in food biotechnology are built. In Food Biochemistry and Food Processing, lead editor Y.H. Hui has assembled over fifty acclaimed academicians and industry professionals to create this indispensable reference and text on food biochemistry and the ever-increasing development in the biotechnology of food processing. While biochemistry may be covered in a chapter or two in standard reference books on the chemistry, enzymes, or fermentation of food, and may be addressed in greater depth by commodity-specific texts (e.g., the biotechnology of meat, seafood, or cereal), books on the general coverage of food biochemistry are not so common. Food Biochemistry and Food Processing effectively fills this void. Beginning with sections on the essential principles of food biochemistry, enzymology and food processing, the book then takes the reader on commodity-by-commodity discussions of biochemistry of raw materials and product processing. Later sections address the biochemistry and processing aspects of food fermentation, microbiology, and food safety. As an invaluable reference tool or as a state-of-the-industry text, Food Biochemistry and Food Processing fully develops and explains the biochemical aspects of food processing for scientist and student alike.

The biochemistry of food is the foundation on which the research and development advances in food biotechnology are built. In Food Biochemistry and Food Processing, Second Edition, the editors have brought together more than fifty acclaimed academicians and industry professionals from around the world to create this fully revised and updated edition. This book is an indispensable reference and text on food biochemistry and the ever increasing developments in the biotechnology of food processing. Beginning with sections on the essential principles of food biochemistry, enzymology, and food processing, the book then takes the reader on commodity-by-commodity discussions of biochemistry of raw materials and product processing. Chapters in this second edition have been revised to include safety considerations and the chemical changes induced by processing in the biomolecules of the selected foodstuffs. This edition also includes a new section on health and functional foods, as well as ten new chapters including those on thermally and minimally processed foods, separation technology in food processing, and food allergens. Food Biochemistry and Food Processing, second edition fully develops and explains the biochemical aspects of food processing, and brings together timely and relevant topics in food science and technology in one package. This book is an invaluable reference tool for professional food scientists, researchers and technologists in the food industry, as well as faculty and students in food science, food technology and food engineering programs.
