Problems solved by technology

[0003] With the gradual enhancement of consumers' health awareness, the food and food ingredients market is more pursuing clean labels, and too many food additives do not conform to the trend of the times
And there are reports in the literature that synthetic emulsifiers cannot be digested by the human body and will increase the risk of intestinal diseases
Although high oil-carrying microcapsule powder can be prepared from modified starch wall materials without adding synthetic emulsifiers, the smoothness of the product is not good and the taste is notable
The preparation of high oil-loaded microcapsule powder by complex coacervation method has complicated process, limited materials and high cost of raw materials
Microcapsule powder prepared from polysaccharide wall materials, the highest oil loading rate is temporarily maintained at 35% to 45%, and the embedding rate is low

Abstract

The invention discloses a preparation method of high-oil-loading microcapsule powder without adding a synthetic emulsifier. Vegetable protein or animal protein is used as a protein raw material, a protein dispersion solution is prepared, after protein denaturation is promoted through primary heat treatment, ketose or aldose is added, wet-method Maillard reaction is promoted through secondary heat treatment, and a pre-prepared wall material solution is generated. Grease is added, and the balance is supplemented with the micromolecular filler. And carrying out vacuum degassing, high-speed homogenization, high-pressure homogenization, UHT sterilization, spray drying and other processes to produce the high-oil-loading microcapsule powder. The microcapsule powder is high in oil carrying rate, high in embedding rate and good in dispersity, and no synthetic emulsifier is added in the microcapsule preparation process.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for preparing oil microcapsule powder, in particular to a method for preparing microcapsule powder with high oil loading rate, high embedding rate and no synthetic emulsifier added. Background technique [0002] In recent years, the use of microencapsulation technology to broaden the use of oils and fats has gradually become a relatively mature high-tech, which has promoted the transformation of the food industry from low-level agricultural product primary processing industry to high-level industry. Almost all edible oils and fats can be embedded with microencapsulation technology, which converts solid or liquid oils at room temperature into fine solid powders. At present, the microencapsulation system is mainly divided into two types, one is to use amphiphilic polysaccharides, modified starches, and protein wall materials, combined with synthetic emulsifiers a...
