Best Answer

The parital hydrogenation of oils and fats reduces the cis double bonds in fats to give them a more solid form at room temperature. As the reduction process takes place at high temperatures, there is thermal isomerization of some of the cis bonds to their trans form.

One of the effects of hydrogenating vegetable oil is to raise the melting temperature, making it a solid instead of a liquid at room temperature.


How are unsaturated vegetable oils hardened?

Unsaturated vegetable oils tend to be liquid at room temperature, but they can also be 'hardened', through a chemical process called hydrogenation, to make them solid at room temperature.


Why is the vegetable ghee is not good for health?

vegetable ghee is more saturated then vegetable oil. More double bonds are present in oil compared to vegetable hence oil is better than ghee. More details can be found in hydrogenation of fats.
