Problems solved by technology

Cottonseed oil is one of the four traditional edible vegetable oils in China. It exceeds corn oil. It contains a large amount of essential fatty acids and has good shortening properties. It is known as a natural shortening without trans fatty acids. However, due to People misunderstand cottonseed oil. Cottonseed oil has not been well utilized. Essential fatty acids are essential to provide energy for the body. Generally, they are synthesized by themselves or obtained from external objects. Refined cottonseed oil contains a variety of essential fatty acids. , especially the content of linoleic acid in refined cottonseed oil is particularly high, which can effectively inhibit the rise of cholesterol in the blood and maintain the health of the human body. Conventional refined cottonseed oil is generally orange-yellow or brown, and the fatty acid composition contains 23.9% palmitic acid , 2.09% stearic acid, 14.87% oleic acid, 55.24% linoleic acid, and the remaining fatty acid content is less than 1%. The refined cottonseed oil has removed toxic substances such as gossypol and can be eaten by humans, but conventional refined cottonseed oil Contains a certain amount of fat with high melting point, which is not conducive to the absorption and utilization of the human body

Abstract

The invention belongs to the technical field of fine and deep processing of cottonseed oil, and particularly discloses high-linoleic acid cottonseed oil and a preparation method thereof. The high-linoleic acid cottonseed oil contains more than 81% of unsaturated fatty acid and more than 60% of linoleic acid, the linoleic acid content in cottonseed oil stearin is more than 50%, and the unsaturated fatty acid content is more than 30%. The cottonseed oil has the effect of being healthier than common edible oil, and the rising of cholesterol in blood can be inhibited.

Description
