What is thermal treatment of food?

Thermal treatment of food refers to processes that use heat to alter the physical and chemical properties of food, primarily for preservation, safety, and enhancing flavor. Common methods include cooking, pasteurization, sterilization, and blanching. These processes help eliminate harmful microorganisms, extend shelf life, and improve digestibility while also affecting texture and taste. Overall, thermal treatment is essential in food processing and preparation to ensure food safety and quality.
