GENERAL KNOWLEDGE

Detailed explanation-1: -Vegetables and vanaspati are made from vegetable oils using hydrogen gas. It’s added to oils to make products more solid or spreadable because it’s a translucent, odourless, tasteless, combustible gaseous material. As a result, hydrogen gas is employed in the production of vegetable oil and vanaspati.

Detailed explanation-2: -So the above statement “Vanaspati ghee is obtained by the hydrogenation of vegetable oil” is true.

Detailed explanation-3: -The correct answer is Hydrogen. The gas used in the manufacture of Vanaspati Ghee from Vanaspati Oil is Hydrogen. At high pressure, in the presence of nickel catalyst, hydrogen is mixed with vegetable oils which turn them into vegetable ghee. This process is called the hydrogenation of oils.

Detailed explanation-4: -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-5: -In the hydrogenation process, hydrogen gas reacts with liquid oil at elevated temperatures and pressures in the presence of a solid catalyst. The hydrogenation of edible oils is always carried out as a batch process.
