High-temperature processing of food products

High Temperature Processing of Milk and Milk Products covers many aspects of thermal processing of milk and milk products with particular focus on UHT processing. The book begins with an overview of the major thermal processing technologies: thermisation, pasteurisation, extended-shelf-life (ESL), UHT and in-container sterilisation. It discusses the principles of the technologies, the processing and packaging equipment used, processing issues such as temperature-time profiles, heat stability, fouling and cleaning, and the quality and safety aspects of the products produced. It provides a balance of the engineering aspects of the processes and the chemical, microbiological and sensory aspects of the products. The changes that occur in products during processing and storage, and the related defects which can arise, are central to the book. The discussions of these changes will be an aid to industry personnel in identifying the causes of quality defects in these products and devising measures which can be taken to eliminate or minimise the defects. A unique feature is a chapter on analytical methodologies applicable to thermally processed dairy products. There are also chapters on high-temperature processed products other than white cows' milk, including products based on plant materials, and on non-thermal technologies which may be used in place of or as adjuncts to thermal processing. The book concludes with a chapter outlining some of the challenges with the technologies and treated products, and a compendium of relevant reviews, chapters and books.

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.

High pressure processing is a fast-growing food processing technology and opens the door to nearly-fresh products that retain their sensorial and nutritional qualities. High Pressure Processing of Fruit and Vegetable Products reviews and summarizes the latest advances in novel high-pressure processing techniques for preserving fruits, fruit juices, and their mixtures. It contains basic information on the relation of high-process treatment parameters with the safety and quality of fruit and vegetable juices/products. The book focuses on product quality parameters, nutritional value, bio-active health components, and microbial safety and stability. The main aim of this book is to summarize the advances in the utilization of modern high pressure pasteurization (HPP) treatment to preserve and stabilize fruit and vegetable products. HPP technology is related to the product quality parameters, the content of nutritional and health active components, and the microbial safety and subsequent shelf life. One chapter of this book is devoted to industrial equipment available; other chapters deal with examples of commercial fruit and vegetable products. Another chapter of this book is dedicated to packaging, as packaging of food before HPP is mandatory in this technology. The regulatory aspects for high-pressure treated fruit and vegetable products in different regions of the world (Europe, the United States, Asia, and Australia) are also an important topic dealt within one chapter of the book. The effects of HPP technology on the quality of fruit and vegetable products, namely nutrients and stability, health active components, and sensory aspects, are reviewed in a trio of chapters.

Thermal processing remains one of the most important processes in the food industry.

Assembling the work of a worldwide panel of experts, this volume highlights topics vital to the food industry today an

This book attempts to explain the scientific basis for UHT sterilization and aseptic filling, as well as describe the processes and equipment used. I have tried to avoid producing merely a catalogue of sterilizers and aseptic fillers. Instead I have attempted to explain the principles on which the different types of plant operate, and discuss the factors which influence performance, so that information given by manufac turers may be assessed by readers in relation to their own processing requirements. Statements are generally supported by references. Where no re ference is given, personal experience or my interpretation of the work of others is my justification. Although the book deals mainly with milk and milk products, I hope that the information it contains will be useful to those dealing with other products, since the principles of processing are in general the same. The book is based on more than 30 years' involvement with research into UHT processing and aseptic filling. During this time I have been fortunate to work with and to talk to many people from whom I have learned a great deal. I benefited from conta.cts with Dr T. R. Ashton (England) and Professor H. Hostettler. (Switzerland), who were pioneers in the commercial development of UHT milk. More recently I have been privileged to know and work with research workers in many countries having a common interest in UHT processing. Of these, I should mention particularly Professors E. L. Thomas, V. A.

A Compilation or Research Pertaining to Foods and Nutrition in Academic, Gevernmental and Industrial Laboratories.

Computational Fluid Dynamics (CFD) has been applied extensively to great benefit in the food processing sector. Its numerous applications include: predicting the gas flow pattern and particle histories, such as temperature, velocity, residence time, and impact position during spray drying; modeling of ovens to provide information about temperature and airflow pattern throughout the baking chamber to enhance heat transfer and in turn final product quality; designing hybrid heating ovens, such as microwave-infrared, infrared-electrical or microwave-electrical ovens for rapid baking; model the dynamics of gastrointestinal contents during digestion based on the motor response of the GI tract and the physicochemical properties of luminal contents; retort processing of canned solid and liquid foods for understanding and optimization of the heat transfer processes. This Brief will recapitulate the various applications of CFD modeling, discuss the recent developments in this field, and identify the strengths and weaknesses of CFD when applied in the food industry. ​

During the past decade, consumer demand for convenient, fresh-like, safe, high-quality food products has grown. The food industry has responded by applying a number of new technologies including high hydrostatic pressure for food processing and preservation. In addition, food scientists have demonstrated the feasibility of industrial-scale high pressure processing. This technology is of specific interest to the food industry because it provides an attractive alternative to conventional methods of thermal processing, which often produce undesirable changes in foods and hamper the balance between high quality (color, flavor, and functionality) and safety. In addition, it offers opportunities for creating new ingredients and products because of the specific actions of high pressure on bio logical materials and food constituents. It allows food scientists to redesign exist ing processes and to create entirely new ones using high pressure technology alone or in combination with conventional processes (e. g. , pressure-temperature combinations ). Researchers have investigated high pressure processing for the past century. Scientists such as Hite and Bridgman did pioneering work at the turn of the 20th century. Then during the 1980s and 1990s, there was a large effort to investigate the effects of high pressure on biological materials, particularly foods. The initial research activities in the late 1980s and early 1990s focused on exploratory activ ities in the food area.

Food Preservation has become an integral part of the food processing industry. There are various methods of food preservation; drying, canning, freezing, food processing etc. Food processing is one the method of food preservation which is the set of methods and techniques used to transform raw ingredients into food or to transform food into other forms for consumption by humans or animals either in the home or by the food processing industry. Canning is one of the various methods of food preservation in which the food is processed and then sealed in an airtight container. This process prevents microorganisms from entering and proliferating inside. Dehydration is the process of removing water or moisture from a food product. Food dehydration is safe because water is removed from the food. Freezing is also one of the most commonly used processes commercially and domestically for preserving a very wide range of food including prepared food stuffs which would not have required freezing in their unprepared state. Benefits of food processing include toxin removal, preservation, easing marketing and distribution tasks, and increasing food consistency. In addition, it increases seasonal availability of many foods, enables transportation of delicate perishable foods across long distances and makes many kinds of foods safe to eat by deactivating spoilage and pathogenic micro organisms. Nanotechnology exhibits great potential for the food industry. New methods for processing nanostructures are being developed having novel properties that were not previously possible. As such, due to the recent up gradation of preservation techniques, the preservation industry is also growing almost at the same rate as the food industry which is about 10 to 12% per year. The purpose of this book is to present the elements of the technology of food preservation. It deals with the products prepared from various fruits and vegetables commercially. Relevant information on enzymes, colours, additives, flavours, adulteration, etc., has been given. This book also contains photographs of equipments and machineries used in food preservation. This book will be very useful for new entrepreneurs, food technologists, industrialists, libraries etc.
