"Understand how water activity can determine food quality with this exhaustive guide This second edition of Water Activity in Foods furnishes those working within food manufacturing, quality control, and safety with a newly revised guide to water activity and its role in the preservation and processing of food items. With clear, instructional prose and illustrations, the book's international team of contributors break down the essential principles of water activity and water--food interactions, delineating water's crucial impact upon attributes such as flavor, appearance, texture, and shelf life. The updated and expanded second edition continues to offer an authoritative overview of the subject, while also broadening its scope to include six newly written chapters covering the latest developments in water activity research. Exploring topics ranging from deliquescence to crispness, these insightful new inclusions complement existing content that has been refreshed and reconfigured to support the food industry of today. This essential text: Helps to build a full understanding of water activity as it relates to the production of food Spans both the theoretical and practical dimensions of water activity Features six new chapters detailing current progress in water activity research Includes frequent illustrations to clearly demonstrate water activity process Food science students, engineers, and industry professionals alike will find Water Activity in Foods a practical and informative work that makes understanding this core aspect of food manufacturing an engaging and accessible process. Water activity (or aw) is a measure of the extent to which water is "available" to interact with other, non-aqueous materials. The concept of water activity is crucial in food science. William James Scott showed in 1953 that microorganisms have a limiting aw level for growth. It is now generally accepted that aw is more closely related to the microbial, chemical, and physical properties of foods and other natural products than is total moisture content. Specific changes in color, aroma, flavor, texture, stability, and acceptability of raw and processed food products have been associated with relatively narrow aw ranges. Next to temperature, aw is considered one of the most important parameters in food preservation and processing. It has a pivotal effect upon the physical and chemical stability of foods"--

High-pressure processing (HPP) represents an industrially relevant solution to the growing consumer demand for wholesome, fresh-tasting foods, where application of pressure assures food safety. Through 31 chapters grouped into 7 relevant sections, the book comprehensively reviews and summarizes current state-of-the-art knowledge, from process engineering, packaging, industrial scale equipment, consumer acceptance, regulations, to application of high pressure in food pasteurization, sterilization, extraction, homogenization, and freezing and thawing. Food safety specialists and process authorities working in both government and food industry sectors will find useful chapters about pressure effects on harmful biological agents as well as approaches to validation of high pressure technology.  Chapters related to high pressure reaction kinetics, process uniformity, mathematical modeling, pressure effects on proteins, enzymes starch and bioactive co mpounds, and structural changes in pressure treated foods will be particularly beneficial for graduate and undergraduate students to discover the latest information on high pressure preservation principles. Chapters concerning high pressure applications in different food industry sectors will serve as excellent reference to food industry professionals, in particular to those involved in the processing of products such as meat, seafood, beverage, dairy, eggs, fruits and vegetable products. .

Since its inception in 2002, the Central European Food Congress (CEFood) has been a biannual meeting intended for food producers and distributors as well as researchers and educators to promote research, development, innovation and education within food science and technology in the Middle European region with a tight connection to global trends. The 6th CEFood, held in Novi Sad, Serbia, May 23-26, 2012, highlighted the novel technologies and traditional foods aimed at both the European and global markets. Specifically, CEFood 2012 focused on the latest progress in fundamental and applied food science, research and development, innovative technology, food ingredients, novel trends in nutrition and health, functional and bioactive food, food engineering, food safety and quality and the food and feed market. This book will consist of contributions from various presenters at CEFood 2012, covering the major themes of this Congress. Chapters contributed by expert presenters from the 6th CEFood Congress of 2012 Highlights the novel technologies of food science Discusses the future of the food industry and food research.

Contains information on post-harvest handling and marketing operations and storage of fresh and processed products. Highlights technology which, when combined, has a positive and synergistic effect in preventing biochemical and physicochemical reactions and microbial growth - the main causes of quality losses in fruits and vegetables. Suggested methodologies combine technologies such as mild heat treatment, water activity reduction, lowering of the pH and use of anti-microbial substances to realize the potential of minimally processed, high-moisture fruit products. These relatively new technologies have been successfully applied to several important tropical and non-tropical fruits in different countries of Latin America.
