A kind of preparation technology of β-carotene microcapsule

Abstract

The invention relates to a beta-carotene microcapsule and a preparation technology thereof. The technology comprises the following steps: mixing corn starch which contains beta-carotene crystals and microhole ocentyl succinic anhydride and serves as a core material, an oil phase consisting of plant oil, an antioxidant and the like and a water phase consisting of a wall material, an antioxidant, a dispersant, water and the like according to a ratio, homogenizing to prepare microemulsion, and performing spray drying to prepare beta-carotene microcapsule powder. In a preparation process, no organic solvent needs to be added, and an obtained product keeps the bioactivity, is stable to the photo-thermal property and is extremely high dissolvability in cold water; processing, transportation and storage are facilitated; the safety, the flowability, the taste and the water solubility of the product are greatly improved; the beta-carotene microcapsule is a high-quality health food and food pigment raw material. The yield of the beta-carotene microcapsule prepared by the technology is high, and the preparation method is suitable for batch preparation of the beta-carotene microcapsules; continuous large-scale production is realized.

Description

technical field [0001] The invention relates to the technical field of production of beta-carotene microcapsules, in particular to a preparation process of beta-carotene microcapsules. Background technique [0002] β-carotene is one of the carotenoids and is an edible oil-soluble pigment. Due to the difference in concentration, its color can cover all color systems from red to yellow. It is the most common pigment in nature. Many natural foods such as: green vegetables, sweet potatoes, carrots, spinach, papaya, mango, etc., are rich in β-carotene. β-carotene is an antioxidant with detoxification effect and an indispensable nutrient for maintaining human health. It has significant functions in anti-cancer, prevention of cardiovascular disease, cataract and anti-oxidation, and then prevents aging and aging-induced diseases. Various degenerative diseases. The Food and Agriculture Organization of the United Nations and the World Health Organization Joint Expert Committee on Fo...

Problems solved by technology

For the selection of microcapsule wall materials, leather gelatin or animal gelatin is mostly used in traditional techniques. Although coating can also be completed to a certain extent, and the cost is relatively low, leather gelatin and animal gelatin often contain more Harmful substances such as cadmium, arsenic, and aflatoxin have been unable to meet the current product safety and hygiene standards

In addition, gelatin-coated products have poor fluidity and poor water solubility, especially not conducive to cold water diffusion and poor release, which greatly affects the use effect of the product
