Effects of oxidation Reaction in Everyday Life
1)Rancidity of food:It is a slow oxidation of oils and fats present in food material resulting in some bad small and taste.
Rancidity Of food can be prevented by:
1)Adding Anit-Oxidants to food containing fats and oils.
(BHA-Butylated Hydroxy Anisole)
(BHT-Butylated Hydroxy Toulene)
2)By packing fat and oil containing food in nitrogen gas.
3)By keeping food in refrigerator.
4)By storing food in air tight containers.
5)By storing food away from light.
2)Corrosion of metal
The process in which metals are eaten up gradually by the action of air,moisture or chemicals on their surface.
For Ex:Rusting of iron
