Detailed explanation-1: -In the food industry, hydrogen is added to oils (in a process called hydrogenation) to make them more solid, or ‘spreadable’. Hydrogenated oils can be sold directly as ‘spreads’, but are also used in the food industry in the manufacture of many foodstuffs such as biscuits and cakes.
Detailed explanation-2: -Hydrogenation is a chemical process that adds hydrogen to the unsaturated bonds on the FA chains attached to the TAG backbone. In this way, an unsaturated fat can be turned into a saturated fat and increase its melting point (List and King, 2006).
Detailed explanation-3: -The hydrogenation process involves sparging the oil at high temperature and pressure with hydrogen in the presence of a catalyst, typically a nickel compound.
