In the absence of antioxidant food additive oxidation of unsaturated fats takes place rendering to foul smell and discoloration of food. Different kinds of antioxidants foods act in a different ways but the end result is to delay or minimize the process of oxidation in food. Some antioxidants foods additives combine with oxygen to prevent oxidation and other prevent the oxygen from reacting with the food leading to its spoilage. Types of anti-oxidant agent:
  1. Anti-browning agent
  2. Antioxidant
  3. Antioxidant synergist
Some popular antioxidant foods mostly as antioxidant vitamins:

a) Ascorbic acid- E300
Antioxidant vitamins include Ascorbic acid (vitamin C) this antioxidant vitamin is used in beers, cut fruits, dried potatoes and jams.
