Impact Of Processing On Food Safety

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.

Covers a Host of Groundbreaking Techniques Thermal processing is known to effectively control microbial populations in food, but the procedure also has a downside―it can break down the biochemical composition of foods, resulting in a marked loss of sensory and nutritional quality. Processing Effects on Safety and Quality of Foods delineates three decades of advances made in processing techniques that produce microbiologically safe foods, while maintaining their sensory and nutritive properties. Addresses the Entire Food Processing Industry With an international team of more than 35 renowned contributors, this book presents evaluation techniques that yield reliable estimations of microbiological, physicochemical, nutritive, and sensory characteristics. Each chapter discusses the processing effects of relevant technologies and includes the basics of microbial kinetics, sensory evaluation, and the perception of food quality. A sampling of the techniques covered: Hermetically sealed containers Acrylamide formation Dried foods Irradiated foods Pressure-assisted thermal processing Pulsed electric field processing Processing Effects on Safety and Quality of Foods addresses the entire food processing industry, including food modeling, optimization, and proper design of manufacturing plants. It is the first of its kind―a single, sound reference that explores all of the different aspects involved in evaluating processing effects in food safety and quality.

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.

How safe is our food supply? Each year the media report what appears to be growing concern related to illness caused by the food consumed by Americans. These food borne illnesses are caused by pathogenic microorganisms, pesticide residues, and food additives. Recent actions taken at the federal, state, and local levels in response to the increase in reported incidences of food borne illnesses point to the need to evaluate the food safety system in the United States. This book assesses the effectiveness of the current food safety system and provides recommendations on changes needed to ensure an effective science-based food safety system. Ensuring Safe Food discusses such important issues as: What are the primary hazards associated with the food supply? What gaps exist in the current system for ensuring a safe food supply? What effects do trends in food consumption have on food safety? What is the impact of food preparation and handling practices in the home, in food services, or in production operations on the risk of food borne illnesses? What organizational changes in responsibility or oversight could be made to increase the effectiveness of the food safety system in the United States? Current concerns associated with microbiological, chemical, and physical hazards in the food supply are discussed. The book also considers how changes in technology and food processing might introduce new risks. Recommendations are made on steps for developing a coordinated, unified system for food safety. The book also highlights areas that need additional study. Ensuring Safe Food will be important for policymakers, food trade professionals, food producers, food processors, food researchers, public health professionals, and consumers.

Principles and Practices for the Safe Processing of Foods presents information on the design, construction, and sanitary maintenance of food processing plants. This book also provides guidelines for establishing and implementing the Hazard Analysis Critical Control Points (HACCP) System and for training personnel in hygienic practices. This text is divided into 13 chapters and begins with the assessment of corporate policies concerning the controlled production of clean, wholesome foods in a sanitary manner. The next chapters deal with some of the requirements for safe food processing, including the establishment and implementation of HACCP rules, building status, sanitation, and personnel. A chapter briefly covers the structure of some microorganisms that affect safe food, such as viruses, bacteria, and fungi. This topic is followed by discussions of the biological factors underlying food safety, preservation, and stability; the principles and application of microbiological control methods; pathogenicity and pathogen profiles; and enzymes and their importance in food spoilage. The last chapters examine the aspects of microbiological safety in food preservation technologies and the criteria for ingredients and finished products. This book will prove useful to food manufacturers, policy makers, and public health workers.
