Microencapsulated food preservative and preparation method thereof

Abstract

The invention discloses a microencapsulated food preservative and a preparation method thereof. The microencapsulated food preservative is prepared from the following ingredients in parts by mass: 6-10 parts of glyceryl monostearate, 7-9 parts of stearic acid, 4-6 parts of and sucrose fatty acid ester, 6-10 parts of xylitan monostearate, 4-8 parts of sorbitan monopalmitate, 2-4 parts of benzoic acid, 4-6 parts of sodium benzoate, 4-8 parts of sorbic acid, 10-12 parts of calcium propionate, 5-7 parts of propyl p-hydroxybenzoate, 6-8 parts of dehydroacetic acid, 5-7 parts of sodium dehydroacetate, and 4-6 parts of sodium diacetate. The microencapsulated food preservative disclosed by the invention is high in retention rates in processing cycles of the foods, as well as good in usage effect and stability; moreover, the influence of the preservative on fermented foods is much smaller. Compared with preservative preapred by water-soluble wall-material microencapsulation technologies, the preservative treated by the preparation method disclosed by the invention has greatly enhanced tolerance to water and stirring.

Description

technical field [0001] The invention relates to the field of food addition, in particular to a microcapsule food preservative and a preparation method thereof. Background technique [0002] Adding preservatives is a relatively common method for extending the shelf life of existing foods. Food companies generally add preservatives directly without pretreatment. Because the preservatives used in food must meet the requirements of the scope and amount of use in the Hygienic Standards for the Use of Food Additives of the People's Republic of China. These preservatives have different inhibitory effects on different microorganisms. Usually, the greater the amount of the same preservative added , the better the anti-corrosion effect. Contents of the invention [0003] The invention provides a microcapsule food preservative and a preparation method thereof. The preservative of the invention has a high preservation rate during food processing, has good product use effect and stabi...
