Problems solved by technology

However, this technical solution has two defects: first, the water phase is prepared under normal pressure, which is easy to form a water-air two-phase miscible system, which is not conducive to the close combination of carotenoids and water phase. Carotene aggregates to form large particles or floats up to demulsify and other unstable factors; in addition, due to factors such as surface tension and temperature drop, the oil will aggregate, float on the surface, and adhere to the tank wall, etc. The high-speed shear dispersion on the working surface of the emulsifier, the temperature difference and the relatively long time of passing through the working surface make the oil phase aggregate and form large particles, which has a great impact on the stability and embedding rate of carotenoids
It also overcomes the industry problems of conventional carotenoid products: high loss rate during processing, serious degradation of trans content, and high solvent residue in products

Abstract

The invention provides a preparation method of carotenoid, and belongs to the technical field of carotenoid processing. The preparation method comprises the following specific steps of: performing vacuum inert gas filling positive pressure emulsification stirring blending on carotenoid and / or a diluent and / or a dispersing agent and / or a filling agent, automatically controlling ultrahigh-temperature instantaneous melting, performing inert gas positive pressure protection, directly conveying to an emulsification shearing surface, performing vacuum emulsification, performing rapid cooling and / or performing spray drying, and obtaining a carotenoid emulsion or powder product by preparation. By optimizing the technological process and various limiting conditions of carotenoid preparation, the loss rate of carotenoid can be effectively reduced; the stability and bioavailability of carotenoid are improved; and the carotenoid prepared by the invention has the advantages of small particle size, high all-trans component content and low loss rate.

Description

technical field [0001] The invention belongs to the technical field of carotenoid processing, and in particular relates to a carotenoid preparation method and process flow. Background technique [0002] Carotenoid products are mature products in existing food, medicine, health care products and cosmetics. Carotenoids can not only play a coloring effect, but also have an antioxidant nutritional effect, and some have medical and health effects. [0003] In terms of sources, carotenoids widely exist in nature and can be extracted from natural plants, obtained through microbial fermentation or chemical synthesis. In terms of physical and chemical properties, carotenoids are insoluble in water, have little solubility in oil, and are very sensitive to light, heat and oxygen, which is not conducive to direct application. In the processing of food, medicine, etc., emulsification and embedding technology is usually used to make carotenoids into emulsion or powder products, which is...
