Health-care corn oil and preparation process thereof

Abstract

The invention relates to the technical fields of grease and grease refining processing, in particular to health-care corn oil and a preparation process thereof. The corn oil disclosed by the invention is subjected to the processes of hydration deguming, deacidification, decoloration, deodorization, dewaxing, filtration, filling, finished products acquisition, and the like. When the deodorization is finished, the corn oil is charged with nitrogen at low temperature, and the product quality and the demand on product stability in the processes of production and storage are guaranteed; the deodorization oil temperature of the corn oil provided by the invention is lower than the deodorization oil temperature of common corn oil so that the content of beta-sitosterol and vitamin E is obviously higher than that of common corn oil; and the health-care corn oil has the functions of assisting to reduce blood fat and strengthen immunity.

Description

technical field

[0001] The invention relates to the technical field of oil and oil refining and processing, in particular to a health-care corn oil and a preparation process thereof. Background technique

[0002] Corn oil (also known as corn germ oil) is a high-quality edible vegetable oil. It uses corn germ as raw material and is refined through advanced production processes such as centrifugal separation, degumming, deacidification, decolorization, deodorization, and dewaxing. It contains 86 % of unsaturated fatty acids, of which 56% are linoleic acid, the human body absorption rate can reach more than 97%; the content of saturated fatty acids is 14%. Corn oil is rich in vitamin E, and vitamin E is a natural antioxidant. Vitamin E is specially added to many oily foods to prevent oxidation. Vitamin E has certain effects on human cell division and anti-aging. The vitamin E content in crude corn oil is second only to wheat germ oil, and it still contains 0.8%-1.2% of the oil...
