1) Corrosion
2)Rancidity
3) Antioxidants
Answers
Answer:
RANCIDITY
The condition produced by aerial oxidation of fats and oils in food marked by unpleasant smell and taste is called Rancidity. For Example, Potato Chips when kept in air for a long time gives unpleasant smell and bad taste.
CORROSION
In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen or sulfates. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. ... Because corrosion is a diffusion-controlled process, it occurs on exposed surfaces.
ANTIOXIDANTS
Antioxidants are compounds that inhibit oxidation. Oxidation is a chemical reaction that can produce free radicals, thereby leading to chain reactions that may damage the cells of organisms. Antioxidants such as thiols or ascorbic acid terminate these chain reactions.
