This book covers the fundamental science and engineering principles governing radio-frequency (RF) applications and provides a solid understanding of industrial RF unit design options, challenges, and opportunities for development. It explains the similarities, differences, advantages, and limitations of RF and microwave heating; discusses dielectric and thermo-physical properties; provides practical perspectives on industrial RF units used in manufacturing food products; examines RF-heating effects on microorganisms, enzymes, and food quality attributes; and explores RF-heating applications beyond food processing, such as waste treatment and counterfeit prevention.

Radio-Frequency Heating in Food Processing: Principles and Applications covers the fundamentals of radio-frequency (RF) heating and the use of RF-heating technologies in modern food processing, preservation, and related industries. Focusing on industrial and lab-scale applications where RF heating has been employed successfully or reported to have potential benefits over conventional heating options, this state-of-the-art reference:Explains the similarities, differences, advantages, and limitations of RF and microwave heating as applied to agricultural productsDescribes fiber-optics temperature sensors and their utility in monitoring temperature during RF and microwave heatingDiscusses the dielectric and thermo-physical properties of agricultural products amenable to RF and microwave heating, presenting measurement techniques, mathematical concepts, and computer simulation modelsProvides practical perspectives on industrial RF units used in manufacturing food products, addressing free-running oscillators and 50-Ω designs for RF heaters and applicatorsUses finite-element formulations to determine design parameters including resonant modes, circuit impedance, and electric field distribution in RF applicatorsExamines RF-heating effects on microorganisms, enzymes, and food quality attributes for products such as poultry, beef, pork, eggs, fish, milk, fruits, vegetables, and seafoodExplores RF-heating applications beyond food processing, such as agricultural product deinfestation, waste treatment, counterfeit prevention, package tracking, and transportation of food from farm to tableRadio-Frequency Heating in Food Processing: Principles and Applications supplies an in-depth overview of the fundamental science and engineering principles governing RF applications, as well as a solid understanding of industrial RF unit design options, challenges, and opportunities for development.
