Heat is lethal to microorganisms, but each species has its own particular heat tolerance. During a thermal destruction process, such as pasteurization, the rate of destruction is logarithmic, as is their rate of growth. Thus bacteria subjected to heat are killed at a rate that is proportional to the number of organisms present.
Preserved foods are packed and hermetically sealed in metal (tin, aluminum), glass, or polymer containers and treated thermally to destroy or suppress the vital activities of microorganisms that could cause spoilage. The process preserves the nutritional value of the products, the caloric content, and the mineral content.

Covers microbial hazards from raw foods through unit operations and packaging. While introducing the principles and processes of industrial-level food canning, the volume clarifies the effects of microorganisms, their ecology, fate, and prevention in canning operations, as well as in other thermal processing techniques, such as aseptic packaging. It covers microbial spoilage and detection for vegetables, fruits, milk, meat and seafood from the raw food materials through individual unit.
Heat kills microorganisms by changing the physical and chemical properties of their proteins. When heat is used to preserve foods, the number of microorganisms present, the microbial load, is an important consideration.
