Question

Excess of vegetable oil is added in the preparation of pickle and the pickle jars are salted before the pickle is added into the jar. What is the purpose of doing so?

• A. Fermentation
• B. Pastuerization
• C. Coagulation
• D. Preservation

Answer 1

The correct option is D Preservation

Preservation involves preventing the growth of bacteria, fungi and other microbes and thus prevents food from spoiling. Salting is done by coating it to meat, mangoes, amla, etc. It basically takes out water from these items and prevents the microbial growth. Oil on the other hand blocks the oxygen supply and makes it difficult for the bacteria and other microorganisms to grow and carry out their life processes.
