Question

5.
Removal of high molecular weight triglycerides with high melting points by chilling the oil, so
that oil remains clear and pourable at refrigeration temperatures; is called:
(a) Neutralization
(b) Winterization
(c) Hydrogenation
(d) Rendering​

Answer 1

Answer:

option c is the answer. this process is called as hydrogenation

Answer 2

Answer:

(b) Winterization

Explanation:

It is also known as fractionate crystallization (a type of fractionation). This process is used for oil refinement, which uses solvents and cold temperatures for the separation of desired components such as triglycerides from the oils and fats. The principle of this process is based on the differences in the solubility, volatility, and melting points between desired components and solvents. It is a most useful biotechnological process. The process involves the dissolution of extract in ethanol and then placing the mixture in a freezer for chilling. The compounds will separate due to differences in their melting and precipitation points. The desired compounds with higher melting points will precipitate first, which are further obtained by separation processes.
