What is the main goal of thermal processes with a lethality step?

The primary objective of thermal processes that incorporate a lethality step is to eliminate pathogens and reduce spoilage microorganisms. This process involves applying heat to food products, which effectively destroys harmful bacteria, viruses, and parasites that can cause foodborne illnesses. The lethality step is carefully designed to achieve a specific level of thermal kill to ensure food safety without compromising the quality of the food.

By focusing on the elimination of pathogens, thermal processing helps ensure that the food product is not only safe for consumption but also has a lower risk of spoilage, thereby extending its edibility period. While enhancing flavor, improving shelf life, and increasing nutritional value are important aspects of food processing, the primary focus of a lethality step is on food safety by effectively controlling microbial load.
