Principles Of Food Science

Principles of Food Science incorporates science concepts into a lab-oriented foods class. This text shows how the laws of science are at work in foods prepared at home and by the food industry. Each chapter includes engaging features, including NEW Going Green environmental updates and Science Matters articles. Other features focus on areas such as current research, technology, and nutrition news. Through lab experiments in the text and Lab Manual, students will practice scientific and sensory evaluation of foods. They will discover how nutrients and other food components illustrate basic chemistry concepts. Additionally, they will examine the positive and negative impacts of microorganisms on the food supply. Students will also explore the variety of careers available to graduates with a food science background. * Students learn the scientific method and how to evaluate scientific studies. The text covers basic chemistry including the basic structure of atoms, the different types and forms of energy in the universe, measuring pH, and water's role as a solvent. * Physical properties, functions, and nutritional impact of the macronutrients are covered in the text. * Students will learn about the micronutrients as well as other microcomponents including phytochemicals, food analogs, and additives. * The positive and negative effects that microbes have on foods are explored. * Various methods of food preservation and packaging are discussed as well as the benefits and drawbacks. Special features throughout the text cover environmental issues, science facts, nutrition news, food science history, technology, recent research, international issues, and more. Experiments at the end of each chapter and in the lab manual include safety tips and lists of needed equipment and supplies. Students employ the scientific method to perform the experiments.

This book focuses on the most common unit operations utilized in modern food processing operations. It contains both descriptive and quantitative analysis of the typical food processes found in modern food processing plants. The descriptive information provides students with background on the process and the impact of the process on food product quality. The quantitative description assists the student in understanding the ability of the process to achieve the desired result and the consequences of improper operation of the process. Examples utilizing different food commodities are incorporated to ensure that the student gains an appreciation of the relationship between commodities and processes.

The first edition of Food processing technology was quickly adopted as the standard text by many food science and technology courses. This completely revised and updated third edition consolidates the position of this textbook as the best single-volume introduction to food manufacturing technologies available. This edition has been updated and extended to include the many developments that have taken place since the second edition was published. In particular, advances in microprocessor control of equipment, ‘minimal’ processing technologies, functional foods, developments in ‘active’ or ‘intelligent’ packaging, and storage and distribution logistics are described. Technologies that relate to cost savings, environmental improvement or enhanced product quality are highlighted. Additionally, sections in each chapter on the impact of processing on food-borne micro-organisms are included for the first time. Introduces a range of processing techniques that are used in food manufacturing Explains the key principles of each process, including the equipment used and the effects of processing on micro-organisms that contaminate foods Describes post-processing operations, including packaging and distribution logistics

The approach to teaching the concepts of food processing to the undergrad uate food science major has evolved over the past 40 years. In most under graduate food science curricula, food processing has been taught on a commodity basis. In many programs, several courses dealt with processing with emphasis on a different commodity, such as fruits and vegetables, dairy products, meat products, and eggs. In most situations, the emphasis was on the unique characteristics of the commodity and very little empha sis on the common elements associated with processing of the different commodities. Quite often the undergraduate student was allowed to select one or two courses from those offered in order to satisfy the minimum standards suggested by the Institute of Food Technologists. The current 1FT minimum standards suggest that the undergradu ate food science major be required to complete at least one food processing course. The description of this course is as follows: One course with lecture and laboratory which covers general characteristics of raw food materials, principles offood preserva tion, processing factors that influence quality, packaging, water and waste management, and sanitation. Prerequisites: general chemistry, physics, and general microbiology.

Large volume food processing and preparation operations have increased the need for improved sanitary practices from processing to consumption. This trend presents a challenge to every employee in the food processing and food prepara tion industry. Sanitation is an applied science for the attainment of hygienic conditions. Because of increased emphasis on food safety, sanitation is receiving increased attention from those in the food industry. Traditionally, inexperienced employees with few skills who have received little or no training have been delegated sanitation duties. Yet sanitation employees require intensive training. In the past, these employees, including sanitation program managers, have had only limited access to material on this subject. Technical information has been confined primarily to a limited number of training manuals provided by regulatory agen cies, industry and association manuals, and recommendations from equipment and cleaning compound firms. Most of this material lacks specific information related to the selection of appropriate cleaning methods, equipment, compounds, and sanitizers for maintaining hygienic conditions in food processing and prepara tion facilities. The purpose of this text is to provide sanitation information needed to ensure hygienic practices. Sanitation is a broad subject; thus, principles related to con tamination, cleaning compounds, sanitizers, and cleaning equipment, and specific directions for applying these principles to attain hygienic conditions in food processing and food preparation are discussed. The discussion starts with the importance of sanitation and also includes regulatory requirements and voluntary sanitation programs including additional and updated information on Hazard Analysis Critical Control Points (HACCP).
