उत्तर
Three ways by which oil acts as a natural preservative in pickles are:
- The oil added to the pickles prevents the pickles from spoiling by preventing air from getting into touch with them.
- It produces a coating atop the pickle, reducing the amount of air available for bacterial growth.
- Antimicrobial activity is also inhibited by oils.
