Intent of Food Processing

A Brief Look at Some Origins of Food Processing
Ensuring Safe Food (HACCP)


Food Preservation

Pillars of Preservation
Foodborne Illness, Infections and Intoxication
Intrinsic and Extrinsic Factors that Affect or Control Microbial Growth
Biological Preservation, Organic Intrinsic Parameters: Acids. pH & Water Activity
Extrinsic Parameter: Storage Temperature, Headspace Gases
