Food Preservation
There are many techniques used to preserve food such as legal food additives, varying levels of food ingredients or components, and new technology.
Legal food additives, among other functions, can prevent oxidation and inhibit or destroy harmful microorganisms.
Vitamin E or vitamin C can serve as an antioxidant in many food products, and benzoate in beverages can act as an anti-microbial agent.
We can preserve food by manipulating the levels of food ingredients or components to inhibit the growth of microorganisms or destroy them.
For example, keep the food low in moisture content (low water activity), high in sugar or salt content, or at a low pH (less than pH 5).
