Food processing is now the biggest industry in the UK and in many other countries. It is also rapidly changing from what was essentially a craft industry, batch processing relatively small amounts of product, to a very highly automated one with continuously operating high speed production lines. In addition, consumers have developed a greater expectation for consistently high standard products and coupled this with demands for such things as a more natural flavour, lower fat etc. The need for an increased knowledge of the scientific principles behind food processing has never been greater. Within the industry itself, increased automation, company diversification and amalgamations etc. have meant that those working in it have often to change their field of operation. Whereas twenty years ago, someone starting work in one branch of the food industry could expect, if he or she so desired, to work there all their working lives, this is now seldom the case. This means that a basic knowledge of the principles behind food processing is necessary both for the student at university or college, and for those already in the industry. It is hoped, therefore, that this book will appeal to both, and prove to be a useful reference over a wide range of food processing.

Physical and chemical interactions between various constituents resulting from processing operations often lead to physical, sensory, and nutritional changes in foods. Combining important information on processing and food quality, Physicochemical Aspects of Food Engineering and Processing describes the effects of various processing technologies on quality changes of different major foods in an integrative manner. Written by Physicochemical Experts in Food Engineering & Processing Part I critically reviews the physicochemical property changes of different foods undergoing selected processes, such as microencapsulation, frying, microwave-assisted thermal processing, high-pressure processing, pulsed electric field processing, and freezing. This section also includes a chapter on the effects of various processing technologies on microbial growth and inactivation. Part II focuses on multiphase food systems made of proteins, seafoods, red meats, and pet foods, and the physicochemical changes they undergo when being processed. Physicochemical Aspects of Food Engineering and Processing covers the engineering, processing, and quality angles equally. It is an extremely useful resource for academic and industrial researchers seeking an up-to-date overview of the increasingly important combination of both sides of food research and development.

The physical and chemical properties of food products have central roles in biotechnology and the pharmaceutical and food industries. Understanding these properties is essential for engineers and scientists to tackle the numerous issues in food processing, including preservation, storage, distribution and consumption. This book discusses models to predict some of the physical-chemical properties (pH, aw and ionic strength) for biological media containing various solutes. In recent years, food production has involved less processing and fewer additives or preservatives. If health benefits for consumers are obvious, it is not only necessary to adapt current processing and preservation processes but also to verify that appropriate technological and health properties are preserved. The authors present established models, but also introduce new tools for prediction with modeling methods that are part of a more general approach to understand the behavior of fluid mixtures and design new products or processes through numerical simulation. Describes the construction of a tool to allow you to predict the physical-chemical properties of foods and bacterial broths Shows you how to apply this tool with complex medias to predict water activity and pH levels and how to integrate this tool with a process simulator Full with theoretical equations and examples to help you apply the content to your data

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.

Chemical and Functional Properties of Food Proteins presents the current state of knowledge on the content of proteins in food structures, the chemical, functional, and nutritive properties of food proteins, the chemical and biochemical modification of proteins in foods during storage and processing, and the mutagenicity and carcinogenicity of nitrogenous compounds. It emphasizes the structure-function relationship as well as the effects of practical conditions applied in food processing on the biochemical and chemical reactions in food proteins and food product quality. The first ten chapters discuss structure-function relationships, methods of analysis of nitrogenous compounds, chemical and enzymatic modifications, nutritive roles, and mutagenicity and carcinogenicity of food proteins. The following six chapters describe the proteins of meat and fish, milk, eggs, cereals, legumes, oilseeds and single cell organisms, and present detailed information on the effects of conditions applied in storage and processing on the reactions in proteins and their impact on quality attributes of food products.

The book is devoted to expanding current views on the phenomena of protein functionality in food systems. Protein functionalities in foods have been the object ofextensive research over the last thirty to forty years and significant progress has been made in understanding the mechanism and factors influencing the functionality of proteins. The functionality of proteins is one of the fastest developing fields in the studies of protein utilization in foods. Currently, a broad spectrum of data related to protein functionality in food systems has been collected, however, much more needs to be known. In this volume, the most important functional properties offood proteins are presented: Protein solubility, water holding capacity and fat binding, emulsifying, foaming, and gelling properties as affected by protein source, environmental factors (pH, temperature, ionic strength) and protein concentration; Relationships between protein conformation, physicochemical properties, and functional properties; Protein functional properties as influenced by various food processing conditions, particularly heat treatment, dehydration, freezing and storage when frozen, extraction and other processes; Effects ofprotein modification on the enhancementofprotein functionality; Utilization ofvarious proteins in improving functional properties in food systems. Those aspects of protein functionality are presented which the author believes to be interesting and most important for protein utilization in food systems.
