Corrosion
Metals are prone to corrosion. It is a slow conversion of metals into some undesirable compounds. This occur may be due to reaction with oxygen, gases, acids etc. When irons react with atmospheric oxygen and moisture, a red layer is formed on the surface of the iron, this process is known as Rusting.
Rancidity
When food containing fats and oils are exposed to the atmosphere, the oxidation of fat and oil occurs, this is known as Rancidity.
Methods to prevent Rancidity
- Store cooking oils from direct sunlight.
- Food should be placed at low temperature.
- By adding antioxidants food can be protected from rancidity.
- Packing material should replace the air with nitrogen.
- Minimize the use of salts in fried foods.
