Problems solved by technology

This invention needs to remove a large amount of solvent contained in the system in the protective colloid, which takes a long time and is not easy to remove completely
[0005] In summary, there is still a lack of a simple preparation method in the prior art, and the prepared natural carotene preparation has good water dispersibility, small particle size, and no use of organic solvents, thereby avoiding the problem of organic solvent residues and improving bioavailability. The preparation method of the natural carotene preparation with high degree of strength, good stability and direct use

Abstract

The invention belongs to the technical field of natural pigment, and particularly relates to a preparation method of a natural carotene preparation. The preparation method of a natural carotene preparation provided by the invention comprises the following steps of taking natural carotene, adding a composite emulsifying agent, and performing uniform mixing so as to obtain an oil phase; taking deionized water, adding water soluble polymer materials to the taken deionized water, and performing stirring until the water soluble polymer materials completely dissolve to obtain an aqueous phase; adding the obtained oil phase to the obtained aqueous phase, and performing shearing and emulsifying twice so as to obtain emulsion; and homogenizing the obtained emulsion, wherein the homogenizing pressure is 50-100MPa, and the homogenizing time is 2-4min. The preparation method of a natural carotene preparation provided by the invention is simple, the natural carotene preparation prepared by the method provided by the invention is good in moisture disperse, excellent in stability and convenient to use. In addition, the natural carotene preparation prepared by the method is small in particle diameter, and the bioavailability of the natural carotene preparation can be significantly improved.

Description

technical field [0001] The invention belongs to the technical field of natural pigments, and in particular relates to a preparation method of natural carotene preparations. Background technique [0002] The main source of natural carotene is palm fruit. It is a natural mixed carotene obtained through molecular distillation extraction and concentration. A mixture of carotene, mainly α-carotene, β-carotene and a small amount of γ-carotene, reddish brown paste viscous liquid, with special smell, soluble in oil but insoluble in water, slightly soluble in ethanol, resistant Good heat and acid resistance, slightly poor light resistance. [0003] Chinese patent CN100421650C discloses a preparation method of water-dispersible carotenoid powder, the steps are as follows: dissolve the crude carotenoid crystals in halogenated hydrocarbons or ester solvents containing antioxidants and emulsifiers, and spray Add it into the stirring ethanol or isopropanol to make carotenoids precipitat...
