Hydrogenated oil is commonly known as “hardened oil”, also known as “vegetable cream”, “Nake creamer”, it can be seen almost everywhere in daily life.
The origin of the name hydrogenated oil:
Hydrogenated oil is also called hydrogenated vegetable oil. It was invented during World War I. At that time, due to frequent wars and lack of supplies, As prices rise, in order to solve the problem of animal oil supply, American scientists use hydrogenation technology to make vegetable oil have the functions of animal oil, thereby replacing animal oil. This is where the term hydrogenated oil comes from.
Animal fat is rich in higher saturated fatty acids, so it often appears in a solid state, while vegetable oil contains more higher unsaturated fatty acids. Therefore, food fried with vegetable oil is not easy to store and is easy to spontaneously dissolve in the air. It deteriorates due to oxidation, causing sour odor and peculiar smell. Since the invention of hydrogenated vegetable oil in 1910, it has been widely used in the food processing and catering industries because it is cheaper than animal-priced oil and is convenient for food storage.
