Glycerin fatty acid ester and preparation method thereof

Abstract

The invention belongs to the technical field of food additives, in particular to anticorrosive food emulsifier glycerin fatty acid ester and a preparation method thereof. The glycerin fatty acid ester is prepared by the following method: esterifying glycerin and A, B and C three kinds of fatty acid serving as raw materials in the presence of an alkaline catalyst, wherein the fatty acid A is propionic acid, the fatty acid B is caprylic acid or capric acid or octyl and decyl acid, and the fatty acid C is lauric acid. The glycerin fatty acid ester after the fatty acid and the glycerin are esterified by certain technology has good anticorrosive effect after being, and has better anticorrosive performance than a product esterified by the single fatty acid and the glycerin. The glycerin fatty acid ester not only can prevent products from deteriorating, but also has the functions of improving quality of the products, delaying the ageing of starch, improving mouthfeel and the like and has superior anticorrosive performance when added into flour food and meat food.

Description

(1) Technical field [0001] The invention belongs to the technical field of food additives, in particular to a preservative food emulsifier glycerin fatty acid ester and a preparation method thereof. (2) Background technology [0002] Food emulsifiers have been widely used in various food fields. They can not only improve product quality and performance, but also delay starch aging and extend product shelf life. my country's meat, rice, pasta and other food industries have developed rapidly, and their products have spread all over the country, but the problems of antisepsis, preventing starch aging, and maintaining the taste of products have always troubled people. At present, enzymes and emulsifiers are generally used in China to prevent the aging of food starch and affect the taste, and food preservatives are usually added for preservation. However, general preservatives usually have certain hazards and problems such as poor use effect and poor safety, so the use effect is...

Problems solved by technology

However, general preservatives usually have certain hazards and problems such as poor use effect and poor safety, so the use effect is not ideal

[0003] At present, there are some emulsifiers on the market that can play a preservative role and improve product performance, such as glyceryl laurate, glyceryl capricate, etc., but their preservative performance is not ideal, and it is difficult to meet the requirements of users, and using them Although it has been reported to have a synergistic effect, its performance still cannot meet the requirements, and there is an increasing demand for safe emulsifiers with stronger anticorrosion properties
