Abstract

The invention provides a preparation method of phytosterin ester rich in oleic acid, which comprises the following steps: firstly, leading seed fat rich in oletic acid and ethanol to perform alcoholysis reaction under the action of catalyst to obtain fatty acid ethyl ester rich in oleic acid; secondly, leading the fatty acid ethyl ester rich in oleic acid and phytosterin to perform the ester exchange reaction under the action of the catalyst, and removing unreacted ethanol and redundant fatty acid ethyl ester so as to obtain crude phytosterin ester rich in oleic acid; thirdly, obtaining primrose yellow to white thick fluid by decoloring the phytosterin ester, i.e. refined phytosterin ester. The oleic acid content of the seed oil is more than 60 percent; and high-content oleic acid reduces the side reaction and improves the yield of the phytosterin ester. The preparation method does not use deleterious organic solvent and produce deleterious materials during the whole preparation, has lower requirement on reaction condition, and is suitable for industrial mass production of food.

Description

technical field

[0001] The invention relates to a preparation method of a food additive, in particular to a preparation method of a phytosterol ester rich in oleic acid. Background technique

[0002] Phytosterols are the basic chemical components of plants, including β-sitosterol, brassicasterol, stigmasterol, campesterol, etc. Their structures are very similar, and they all contain a steroid nucleus, and there is a hydroxyl group at the 3-position of the steroid nucleus. Under certain conditions, sterols can react with fatty acids and their esters to form phytosterol esters.

[0003] At present, phytosterols have a good cholesterol-lowering effect and have increasingly attracted people's attention. Since the structure of phytosterols is similar to that of cholesterol, they can form a competitive absorption relationship with cholesterol in the small intestine, and can replace part of cholesterol to be absorbed, while phytosterols themselves cannot be used in the human body,...
