    Cooking oil can be converted in vegetable ghee by the process of

    A)  Hydrogenation

    B)  crystallisation

    C)  Oxidation

    D)  distillation

    Correct Answer: A

    Solution :

    [a] Oils (such as vegetable, olive, sunflower) are liquids at room temperature. 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. The use of hydrogenated helps to prolong the shelf-life of the food and maintain flavour stability.
