Question

Among the following, which is/are the process(es) that lead to generation of new fats from existing ones?

• A. Transesterification
• B. Degumming
• C. Hydrogenation
• D. Winterization

Hint:

Transesterification and hydrogenation are processes that chemically alter fats, leading to the creation of new types of fats, whereas degumming and winterization are refining processes.

Answer 1

The Correct Option is A, C

The generation of new fats from existing ones can be achieved by processes that chemically alter the structure of fatty acids or fatty acid esters.
- Transesterification (option A) is the process where an ester reacts with an alcohol, often used in the production of biodiesel by converting vegetable oils or animal fats into fatty acid methyl esters. It results in the creation of new fats.
- Hydrogenation (option C) involves the addition of hydrogen atoms to unsaturated fats, converting them into more saturated fats, commonly used in the production of margarine and solid fats from liquid oils. This process also generates new fats by modifying the original structure.
On the other hand, Degumming (option B) and Winterization (option D) are methods used to refine oils and fats but do not generate new fats. Degumming removes impurities, and winterization is used to remove waxes and other solid substances from oils. Thus, the correct answer is (A) Transesterification and (C) Hydrogenation.
