Problems solved by technology

Although the embedding effect of natural polymer materials in the prior art is better, the embedding rate is low with the increase of drug loading.
And the current evening primrose oil and rosehip oil microcapsule technology is basically limited to spray drying, and the dried products are mesopore, agglomerated products, or flake, rhombus, and needle-shaped after drying and crushing. Severe agglomeration and low degree of dispersion

Abstract

The invention discloses a preparation method of microcapsules composited by evening primrose oil and rosehip oil. The preparation method comprises the steps of picking the evening primrose oil, the rosehip oil and lecithin, conducting vacuum melting, and treating the ingredients as core materials; picking cyclodextrin, Arabic gum and cane sugar, conducting hydration with water, and treating the ingredients as liquid wall materials; mixing the core materials with the liquid wall materials, conducting sufficient emulsification, and obtaining emulsion; making the emulsion be subjected to spray freeze-drying, and obtaining the microcapsules composited by the evening primrose oil and the rosehip oil. According to the preparation method, the spray freeze-drying method is adopted, the drying rate is high, the drying time is short, the production process is simple and flexible, the operation and control are convenient to conduct, and the preparation method is suitable for mass production. The prepared microcapsules are high in oil content, loss of gamma-linolenic acid is reduced to the greatest extent, and oxidative deterioration is not prone to occurring; the microcapsules are good in taste, easy to digest and absorb and high in biological value of functional components; the microcapsules can be eaten directly and can also be prepared into drugs, health products, food additives and cosmetics.

Description

technical field [0001] The invention relates to a preparation method of vegetable oil microcapsules. More specifically, it relates to a preparation method of evening primrose oil and rosehip oil composite microcapsules.
