• C. c) Hydration
  
• D. d) None of the above

Answer 1

The correct option is A a) Oxidation


A)

Explanation:

When fats and oils are oxidised, they become rancid and their smell and taste change. Usually substances which prevent oxidation (antioxidants) are added to foods containing fats and oil. The chips manufacturers usually flush bags of chips with gas such as nitrogen to prevent the chips from getting oxidised.
