Hygiene evaluation of canned food
-should be assessed for hermetic seal of the container and appearance of bulging -Rust: main criteria for disturbed hermetic seal
- Stage 1: points of rust appear on the metallic surface of container
- Stage 2: spots of rust appear on the metallic surface of the container
- Stage 3: erosions appear in the metallic surface of the container
-Bulging: second most criteria for disturbed hermetic seal
- Mechanical: depending on physical factors
- Chemical: tin of the can reacts with organic acids in the food forming hydrogen gas
- Biological (true): microbial growth in canned food (provides the anaerobic environment for bacteria's spores to produce toxins)
