Properties of Water in Foods by D. Simatos,J.L. Multon Pdf

Water is recognized as being an important factor in numerous pheno mena connected with the quality of food. For instance, it plays a part in the textural properties of several commodities. Moreover, water is an essential parameter determining the behaviour of food products in the course of many processing operations : on water, will depend the amount of energy necessary for freezing or dehydrating the product; water will strongly influence the evolution of physical, chemical and biochemical phenomena taking place in the product during processing operations such as heating, drying, etc. Water will also influence the same reactions, as well as the activity of microorganisms, during the storage of food products under various conditions. As a result, all aspects of quality - sensory, nutritional and hygienic properties of the food - will be affected. In all these circumstances, the water content of a product is obviously an important factor, but equally important may be the physical properties of this water, such as its thermodynamic activity and its mobility. Actual ly, the concept of water activity (a ) is now widely used by the food industry and in the legislation of sever')¥l countries. The idea of a small, international meeting devoted to a synthetic review and discussion of knowledge on these various matters, was first developed by Dr. R. B.

The Properties of Water in Foods ISOPOW 6 by David Reid Pdf

Water is recognized as being a critically important determinant of the properties of many foods. It is therefore appropriate to devote a meeting to the topic. The first such meeting was organized by the late Ron Duckworth, and held in 1974 at the University of Strathclyde in Scotland. As a result of this first meeting, the organization known as International Symposium on the Properties of Water (ISOPOW) was born, and since that first ISOPOW meeting there have been five international meetings. At each meeting, participants from academia and from industry have shared state of the science information pertinent to the role of water in foods. Each meeting has served as a review of the current state of knowledge. ISOPOW 6 is the first of these meetings where Ron Duckworth's presence has not been felt, though he clearly attended the meeting in spirit. A lively group of academics and industrial scientists assembled in Santa Rosa, California, to discuss the current state of the science. As meeting chairperson, I must acknowledge the tremendous contributions made by the organizing committee, by the session chairpersons and by the central committee. Without all their help, nothing could have been achieved. Most important to the success of the meeting, however, was the very active participation of all attendees. In all seven sessions, the papers were excellent and their discussion was very spirited.

Water Relationships in Foods by Harry Levine,Louise Slade Pdf

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.

Water Activity: Influences on Food Quality by Louis B. Rockland,George F. Stewart Pdf

Water Activity: Influences on Food Quality is a collection of papers presented at the 1978 International Symposium by the same title, held in Osaka, Japan. This book is a treatise on the influence of bound and free water on the quality and stability of foods and other natural products. This book is organized into seven sections encompassing 33 chapters. The first sections deal with the characterization of moisture sorption isotherms based on both theoretical and applied considerations, as well as the relationship of bound water to the physical and chemical properties of natural products, including foods. The succeeding sections consider the structure of water and the influence of solutes and solute mobility on water activity and the influence of water and water activity on the structural and functional characteristics of proteins, carbohydrates, and proteins. Other sections explore the influence of water activity and temperature on the rates of several important chemical reactions, such as lipid oxidation, vitamin decomposition, browning, and other reactions, which affect the chemical, physical, and nutritional properties of food. These sections also discuss the influence of water activity on food processing and storage practices from both theoretical and applied viewpoints, specifically the application of water activity principals to the processing and preservation of leafy vegetables, cheese, dried fish, and other products. The final section is devoted to the influences of water activity on the behavior of food-related microorganisms. This section emphasizes the role of solvents in controlling water activity and the related survival of certain microorganisms. This book will prove useful to food scientists and researchers.

Food Properties and Computer-Aided Engineering of Food Processing Systems by R.P. Singh,Augusto G. Medina Pdf

Food properties, whether they concern the physical, thermodynamic, chemical, nutritional or sensory characteristics of foods, play an important role in food processing. In our quest to gain a mechanistic understanding of changes occurring during food processing, the knowledge of food properties is essential. Quantitative information on the food properties is necessary in the design and operation of food processing equipment. Foods, because of their biological nature and variability, vary in the magnitude of their properties. The variation in properties offer a challenge both in their measurement and use in the food processing applications. Often a high level of precision in measurement of properties is not possible as the measurement method may itself cause changes to the product, resulting in a variation in the obtained values. Recognizing the difficulties in measurement of food properties, and the lack of completeness of such information, several research programs have been in existence during the last two decades. In Europe, a multinational effort has been underway since 1978. The first project supported by COST (European Cooperation in the Field of Scientific and Technical Research), was titled COST 90 "The Effect of Processing on the Physical Properties of Foodstuffs". This and another project COST 90bis have considerably added to our knowledge of measurement methods and data on a number of physical properties. Two publications that summarize the work conducted under 1 2 these projects are Physical Properties of Foods and Physical Properties of Foods .
