# What is the process in which hydrogen is introduced to vegetable oils to make them saturated known as?

Jan 2, 2017

$\text{Hydrogenation............}$

#### Explanation:

Hydrogenation of vegetable oils and animal fats is a standard industrial procedure. The more saturated a fat is, the longer its shelf-life. Why? Because a site of unsaturation, an olefinic bond, is potentially a reactive site that can be oxidized.

Of course, these days we are sold on the benefits of unsaturated fats. $\text{A priori}$, an unsaturated fat will yield less energy upon combustion, and the $C = C$ double bond is harder to metabolize than $C - H$ bonds.
