This book was released on 2022-10-06 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave and Radio Frequency Heating in Food and Beverages discusses advanced heating techniques based on electromagnetic and electro-technologies, including radiative or microwave (MW) dielectric heating, radio-frequency (RF) or capacitive dielectric heating, infrared (IR) heating, ohmic and magnetic induction heating. Unlike conventional systems where heat energy is transferred from a hot medium to a cooler product resulting in large temperature gradients, electro-heating involves the transfer of electromagnetic energy directly into the product, initiating volumetric heating due to frictional interaction between water molecules and charged ions (i.e., heat is generated within the product). - Provides basic principles and mechanisms of electromagnetic heating and microwave - Explores microwave and radio-frequency (RF) effects on quality and nutrients in foods - Presents the commercial applications of microwave and RF heating in the pasteurization and sterilization of foods and beverages
