Applications of Microwaves in Meat Industries

This chapter explores the application of microwave (MW) technology in meat processing. MW technology, operating within the electromagnetic spectrum of 300 MHz to 300 GHz, offers rapid heating, cooking, pasteurization, sterilization, freezing, and defrosting of meat. Unlike conventional methods, MW cooking retains higher levels of vitamins such as retinol, thiamine, and riboflavin, although it can degrade meat texture and promote the formation of undesirable compounds. Microwave pasteurization and sterilization significantly reduce processing time and ensure microbial safety, though challenges such as uneven energy distribution remain. MW freezing and defrosting have shown promise in improving meat quality by controlling ice crystal formation, thus reducing texture damage. The chapter concludes by emphasizing the need for further research and technological improvements to maximize the benefits of MW processing while minimizing its limitations.
