Question

Why are mangoes pickled in oil?

• A. To enhance growth of bacteria.
• B. To prevent bacterial growth.
• C. To preserve them from spoilage.
• D. To increase nutritional value.

Answer 1

Answer: (B), (C)

The correct options are
B To prevent bacterial growth.
C To preserve them from spoilage.

Pickles made from mango and other vegetables are preserved using oil and vinegar. This prevents the spoilage of pickles as oil forms a hydrophobic layer on them, thus preventing the growth of bacteria which otherwise would grow in moist conditions. Therefore, the bacteria will not be able to survive in this environment.
