Problems solved by technology

[0012] However, both conjugated linoleic acid and docosahexaenoic acid are long-chain polyene highly unsaturated fatty acids, which are insoluble in water and easily oxidized and decomposed by the external environment, which is not conducive to storage, transportation and application.
This causes great inconvenience to users

Abstract

The invention relates to conjugated linoleic acid and docosahexenoic acid microencapsulated powder. The conjugated linoleic acid and docosahexenoic acid microencapsulated powder comprises a wall material, a capsule core, auxiliary agents, an emulsifying agent or a surfactant, wherein two greases of conjugated linoleic acid and docosahexenoic acid are co-used as the capsule core. A microencapsulated product is obtained by adding the capsule core into the wall material in a solution state, adding the auxiliary agents, the emulsifying agent or the surfactant to carry out emulsification, and spray drying. The conjugated linoleic acid and docosahexenoic acid microencapsulated powder can be used as a health-care food, a nutritional food capable of being taken by direct brewing, a food additive or a nutrient supplement, and has a plurality of functions.

Description

technical field [0001] The invention relates to a microencapsulated powder of conjugated linoleic acid and docosahexaenoic acid prepared by a spray drying method. Background technique [0002] Microcapsule (Microcapsule) refers to a micro-container or package with a polymer wall. Its size generally ranges from 5 to 200 μm, and its shape varies, depending on the raw materials and preparation methods. Microencapsulation technology (Microencapsulation technology) refers to the technology of embedding solids, liquids or gases in tiny and sealed capsules, isolated from the external environment, so that they can be released at a controlled rate only under specific conditions. The process of preparing microcapsules using microcapsule technology is called microencapsulation (Microencapsulation). [0003] Microencapsulation began in the 1930s and is a rapidly developing new technology today. [0004] Microencapsulation methods can be roughly divided into three categories: 1. Physi...
