In the food industry, controlling crystallization is a key factor in quality as it relates to texture, with some foods requiring the promotion of crystallization and others its prevention. In the first publication to focus specifically on this process as it applies to food, Crystallization in Foods covers fundamental principles in ice, sugar, and lipid crystallization, and their applications. Drawing on examples throughout of the practical use and impact of crystallization on food structure, texture, and quality; and enhanced with numerous equations and illustrations, Crystallization in Foods is a valuable resource for food engineers and other scientists working with crystallization in foods, particularly in the dairy, confectionery, frozen foods, and baked goods industries. In addition, this book may be of interest to scientists and other professionals in the personal care and cosmetics industry, which shares some of the same quality and texture concerns as 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.

Traditional food and bioprocessing technologies are facing challenges due to high expectation from the consumers and producers for better quality and safety, higher process efficiency, and products with novel properties or functionalities. For this reason, in the last few years new forms of physical energies have been explored to propose alternatives to traditional processing technologies. Acoustic energy has the potential to replace or partially substitute conventional processes, and at the same time offer unique opportunities in the characterization of foods and biomaterials. This book is a resource for experts and newcomers in the field of power ultrasound, gives insights into the physical principles of this technology, details the latest advancements, and links them to current and potential applications in the food and bioprocessing related industries.

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.
This book was developed from the papers presented at a symposium on "Water Relationships in Foods," which was held from April 10-14, 1989 at the 197th National Meeting of the American Chemical Society in Dallas, Texas, under the auspices of the Agricultural and Food Chemistry Division of ACS. The editors of this book organized the symposium to bring tagether an es teemed group of internationally respected experts, currently active in the field of water relationships in foods, to discuss recent advances in the 1980's and future trends for the 1990's. It was the hope of all these con tributors that this ACS symposium would become a memorable keystone above the foundation underlying the field of "water in foods. " This strong foundation has been constructed in large part from earlier technical conferences and books such as the four milestone International Symposia on the Properties of Water (ISOPOW I-IV), the recent IFT BasicSymposium on "Water Activity" and Penang meeting on Food Preservation by Maisture Control, as well as the key fundamental contributions from the classic 1980 ACS Symposium Series #127 on Water in Polymers, and from Felix Franks' famous seven-volume Comprehensive Treatise on Water plus five subsequent volumes of the ongoing Water Science Reviews. The objective of the 1989 ACS symposiumwas to build on this foun dation by emphasizing the most recent and maj or advanc.
