Processing Effects on Safety and Quality of Foods delineates three dec
Food processing is expected to affect content, activity and bioavailability of nutrients; the health-promoting capacity of food products depends on their processing history. Traditional technologies, such as the use of antimicrobials and thermal processing, are efficient in increasing nutritional value to an extent, though they may not be effective at addressing food safety, particularly when it comes to maintaining the food's molecular structure. Modern food processing plants improve the quality of life for people with allergies, diabetics, and others who cannot consume some common food elements. Food processing can also add extra nutrients, such as vitamins. Processed foods are often less susceptible to early spoilage than fresh foods and are better suited for long-distance transportation from the source to the consumer. However, food processing can also decrease the nutritional value of foods and introduce hazards not encountered with naturally occurring products. Processed foods often include food additives, such as flavourings and texture-enhancing agents, which may have little or no nutritive value, and may in fact be unhealthy. This book deals with the subject of food processing in a unique way, providing an overview not only of current techniques in food processing and preservation (i.e., dairy, meat, cereal, vegetables, fruits and juice processing, etc.) but also the health and safety aspects: food technologies that improve nutritional quality of foods, functional foods, and nanotechnology in the food and agriculture industry. The text also looks into the future by defining current bottlenecks and future research goals. This work will serve as a ready reference for the subject matter to students and researchers alike.
The contents of this book are the proceedings of the ACS symposium, "Impact of Processing on Food Safety," which was held April 16-17, 1997, at the American Chemical Society National Meeting in San Francisco, CA. This symposium brought together re searchers from diverse backgrounds in academia, government, and industry. Twenty speakers discussed topics ranging from the regulatory aspects of food processing to the microbiological and chemical changes in food during processing. The main goal of food processing is to improve the microbial safety of food by de stroying pathogenic and spoilage organisms. Food processing can also improve food safety by destroying or eliminating naturally occurring toxins, chemical contaminants, and antinutritive factors. Unfortunately, processing can also cause chemical changes that result in the formation of toxic or antinutritive factors. The purpose of this book is to summarize our knowledge of both the beneficial and deleterious effects of processing. Chapter I con siders the consumer's perceptions about food contaminants and food processing. Chapter 2 summarizes the effects of traditional and nontraditional processing methods on microor ganisms in food. Chapters 3-6 review the effects of processing on lipids (fatty acids and cholesterol) in food. Changes in the nutritive value of vitamins and minerals as a result of processing are discussed in chapter 7. Chapter 8 concentrates on how processing reduces the allergenicity of some foods.
Food Processing for Increased Quality and Consumption, Volume 18 in the Handbook of Food Bioengineering series, offers an updated perspective on the novel technologies utilized in food processing. This resource highlights their impact on health, industry and food bioengineering, also emphasizing the newest aspects of investigated technologies and specific food products through recently developed processing methods. As processed foods are more frequently consumed, there is increased demand to produce foods that attract people based on individual preferences, such as taste, texture or nutritional value. This book provides advantageous tools that improve food quality, preservation and aesthetics. Examines different frying techniques, dielectric defrosting, high pressure processing, and more Provides techniques to improve the quality and sensory aspects of foods Includes processing techniques for meat, fish, fruit, alcohol, yogurt and whey Outlines techniques for fresh, cured and frozen foods Presents processing methods to improve the nutritional value of foods

Packed with case studies and problem calculations, Handbook of Food Processing: Food Safety, Quality, and Manufacturing Processes presents the information necessary to design food processing operations and describes the equipment needed to carry them out in detail. It covers the most common and new food manufacturing processes while addressing rele
The processing of food generally implies the transformation of the perishable raw food to value-added products. It imparts benefits, such as the destruction of surface microflora, and inactivation of deleterious enzymes, such as peroxidase, leading to a greater shelf life of the food. It also enhances color and texture while maintaining quality of products and makes them edible. However, it also has an inevitable impact on nutritional quality attributes, such as increase or decrease in certain vitamins and bioactive metabolites among others. Food Processing Technologies: Impact on Product Attributes covers a range of food processing technologies and their effect on various food product attributes, such as bioactive compounds, safety, and sensory and nutritional aspects of the food upon processing. There are eight major parts in the book. Part I covers the conventional processing technologies. Parts II, III, IV, and V deal with various novel processing technologies, including impingement processing technologies, electro-magnetic processing technologies, physico-mechanical processing technologies, and electro-technologies. Part VI introduces chemical processing technologies. Part VII comprise irradiation processing technology, and the final part is focused on biological processing technology, detailing the application of enzymes in food processing. Numerous studies were carried out to find the impact of these processing technologies on various aspects of food and associated health promotion properties. Both positive and negative results were obtained based on nature of foods, processing type, and duration of processing, and this book covers these results in depth.
Consumers around the world have become better educated and more demanding in their identification and purchase of quality health-promoting foods; therefore the food industry requires innovative technologies to provide their clientele with safe and stable foods that meet safety regulations . Improving Food Quality with Novel Food Processing Technologies details novel processing technologies including high pressure processing (HPP) and pulsed electrical fields (PEFs) that can improve the quality of food from functionality, chemistry/microbiology, bioactive quantity, and shelf-life standpoints. The authors discuss how to improve food functionality with high hydrostatic pressure (HHP) and PEFs. They focus on improving the quality and retaining bioactive constituents of fruits and vegetables and improving the quality of dairy, egg, meat, and seafood products with HHP. Broad in scope, the book also reviews the modeling and simulations of HHP inactivation of microorganisms and the relative effects of HHP processing on food allergies and intolerances. It then discusses improving food functionality with PEF processes in dairy and egg products, fruit juices, and wine. A chapter attending to industrial applications of HHP and PEF systems and potential commercial quality and shelf life of food products concludes this discussion. During the past decade, novel processing technologies including HHP, ultrasound, PEF, and advanced heating technologies containing microwave, ohmic heating, and radio frequency have frequently been applied in the processing of foods and beverages. Successful research and identification of economic benefits, including energy and water conservation as well as demonstrated safety and fresh-like quality attributes will improve consumer perception of nonthermal technologies and result in further development by the food industry around the world. In an in-depth exploration of these novel technologies, the book gives you the skills for product development and improvement.
The aim of the food processing is to ensure microbiological and chemical safety of foods, adequate nutrient content and bioavailability and acceptability to the consumer with regard to sensory properties and ease of preparation. Processing may have either beneficial or harmful effects on these properties, so each of these factors must be taken into account in the design and preparation of foods. This book offers a unique dealing with the subject and provides not only an update of state-of-the art techniques in many critical areas of food processing and quality assessment, but also the development of value added products from food waste, safety and nanotechnology in the food and agriculture industry and looks into the future by defining current obstacles and future research goals. This book is not intended to serve as an encyclopedic review of the subject. However, the various chapters incorporate both theoretical and practical aspects and may serve as baseline information for future research through which significant development is possible.
Abstract: The chemical and biochemical effects of food processing on the safety and nutrient value of foods are explored. Modern manufacturing techniques preserve the nutrient and storage qualities of food and protect it from contamination by toxic compounds. Following a discussion of consumer satisfaction, human nutrient needs, and RDAs, the specific effects of processing on vitamins, lipids, minerals, proteins and amino acids are examined. The concepts of fortification, nutrient loss, and optimization of processing conditions are described. Other topics include antinutritional and toxic substances, agricultural residues, food preservatives, and immunological aspects of foods. Both safety and nutritional problems are addressed from a single perspective throughout the text.
