Question

The process of straightening an unsaturated fatty acid to create a more solid fat that resists rancidity is called

Answer 1

Answer:

Hydrogenation.

Explanation:

Two main types of fatty acid are unsaturated fatty acid and saturated fatty acid. The saturated fatty acid has single bond in their structure whereas unsaturated fatty acid has double or triple bond.

The hydrogenation may be defined as the addition of hydrogen molecules to the unsaturated fatty acids that makes them saturated. This process in the presence of palladium  that acts as catalyst for the reaction. The increases in saturation level decreases the rancidity as well.

Thus, the answer is hydrogenation.

Answer 2

Answer:

The correct answer is hydrogenation

Explanation:

The process of straightening an unsaturated fatty to produce more saturated and more solid fat is called hydrogenation. In the process of hydrogenation, the hydrogen is added to the liquid unsaturated fats to convert them into solid fat.  

Hydrogenation helps in increasing the shelf life of the oil by resisting rancidity. Most of the trans fat in our diet is made from the process of hydrogenation. Fully hydrogenated oil contains a very small amount of trans fat and is better than trans fat which is partially hydrogenated.
