Bücher der Reihe Electro-Technologies for Food Processing Series

The technologies that include the use of Ohmic heating, pulse electric fields, and ultraviolet radiation have become more involved in the processing of food products. Focusing on the structural changes that occur in post-process samples, this title examines functional, rheological, and microstructural changes in food exposed to these technologies.

Ohmic heating provides rapid and uniform heating, resulting in less thermal damage than conventional heating and allowing manufacturers to obtain high-quality products with minimum sensorial, nutritional, and structural changes. Ohmic Heating in Food Processing covers several aspects of Ohmic heating: science and engineering, chemistry and physics, biochemistry and nutrition, quality and safety, and development and technology, both basic and applied. It describes the importance of Ohmic technology and how to implement it in practice, addressing basic theory, principles, and applications.Divided into nine sections, this volume covers the basics of Ohmic heating, including a historic overview and fundamental principles; electrical conductivity, its importance, factors that influence it, and data modeling; biological effects of electricity on foods and food components, including microorganisms, enzymes, proteins, carbohydrates, and fats; and Ohmic heating behavior and design parameters. The book also deals with issues in Ohmic heating equipment, Ohmic heating modeling issues, and process validation issues.The authors discuss various applications of Ohmic heating applied to different classes of foods, such as muscle foods (meat, poultry, and fish), dairy products, fruits, and vegetables. They also examine commercially successful applications of food products processed by Ohmic heating and considers applications of Ohmic heating where preservation is not the main focus, for example, blanching, Ohmic thawing, and the potential for Ohmic heating for long-duration space missions.

During the past decade, emerging technologies that include the use of Ohmic heating, pulse electric fields, and ultraviolet radiation have become more involved in the processing of food products. Focusing on the structural changes that occur in post-process samples, this resource brings together respected international experts who examine the functional, rheological, and micro-structural changes in food exposed to these technologies. They examine new and innovative applications and present research findings on their impact on nutritional aspects of protein and carbohydrate, changes in protein foods such as denaturation, and consider synergic effects of protein-starch components.
