Why is cooking oil a mixture?
Vegetable oils are mixtures of TAGs that are liquid because of their high proportion of UFA: e.g., corn oil (88% UFA), soybean oil (87% UFA), and olive oil (90% UFA). Contrary to vegetable oils, fats contain a higher proportion of saturated fatty acids: e.g., butter (47% SFA), human fat (37% SFA).
What is the characteristic of vegetable oil?
characteristics. Vegetable oils, obtained from such oil-bearing seeds as corn (maize), cottonseed, peanuts, palm nuts (coconuts), and soybeans, are 100 percent fat and remain liquid at fairly low temperatures. They are processed to achieve neutral to yellow colour and to eliminate odour or produce mild odour.…
