The process of hydrogenation changes the double bonds in unsaturated fatty acids into single bonds, giving the fat a more solid consistency.
<h3>Hydrogenation of fat</h3>
Fat can be defined as one of the main classes of food that is made up of triesters of glycerol and fatty acids or triglycerides.
At room temperature, fats are solids, while those that are liquid at room temperature are called oils.
Fats can be saturated or unsaturated. But an unsaturated fat can be made saturated through the process of hydrogenation.
Hydrogenation of fat can be defined as the addition of hydrogen in the presence of nickel catalyst to form saturated fat.
