Abstract

The invention discloses a preparation method of corn oil retaining zeaxanthin, and belongs to the technical field of edible oil production. According to the method, squeezed crude oil and leached crude oil are selected for refining, and the method comprises the steps of corn germ selection, crude oil squeezing, degumming, deacidification, dewaxing, decoloration, molecular deodorization and the like. According to the invention, more beneficial substances such as zeaxanthine in the corn oil, including beneficial components such as vitamin E and sterol, can be retained through a proper corn oil preparation process and a proper refining process, harmful components such as mycotoxin and benzopyrene can be effectively removed, and the nutritional value of the corn oil can be improved.

Description

technical field [0001] The invention relates to the technical field of edible oil production, in particular to a preparation method of corn oil retaining zeaxanthin. Background technique [0002] Zeaxanthin, molecular formula C 40 h 56 O, with a molecular weight of 566.88, belongs to the isoprene class, is an oxygen-containing carotenoid, and is isomers with lutein. Most zeaxanthin found in nature is the all-trans isomer. Zeaxanthin is a new type of oil-soluble natural pigment, which is insoluble in water but soluble in organic solvents. It is a derivative of β-carotene, but it cannot be converted into VA in the body and has no VA activity. Poor light and heat stability, especially light has the greatest impact on zeaxanthin; 3+ and Al 3+ The stability is also poor, but for other ions, acids, bases and reducing agent Na 2 SO 3 Wait for more stable. Widely present in green leafy vegetables, flowers, fruits, wolfberry and yellow corn. Pure zeaxanthin is a crystalline...
