Abstract

The invention relates to a preparation method of high-concentration capsanthin. The preparation method comprises the following steps: by taking capsanthin with color value of 150-250 as a raw material, adding an equal amount of alcohol solution prepared by an alkali and an alcohol according to a proportion to perform saponification reaction, performing decompression and concentration, distilling to recover the alcohol, then adding ethyl acetate, uniformly stirring, further adding the ethyl acetate into insoluble matters after centrifugal separation, merging the ethyl acetate phases, then adding pure water, uniformly stirring, performing centrifugal separation, then taking supernatant liquid, further adding the ethyl acetate into the pure water phase, uniformly stirring, performing centrifugal separation, then taking the supernatant liquid, merging all the ethyl acetate phases, performing decompression and concentration, and distilling to recover the ethyl acetate to obtain the high-concentration capsanthin. The preparation method provided by the invention has the advantages of simple and convenient process, relatively low cost and high safety, the color value of the capsanthin is improved by 3-5 times, the total content of carotenoids is improved by about 30%, the performances are stable, the range of applications of the capsanthin is expanded, and the raw material is also provided for preparing high-end products of the capsanthin.

Description

technical field [0001] The invention relates to a preparation method of high-concentration capsanthin. Background technique [0002] Capsanthin is a natural pigment extracted from peppers. Its main components are red pigments such as capsanthin and capsanthin, and yellow pigments such as capsanthin, zeaxanthin and cryptoxanthin. The pigments are all carotenoid pigments. Capsanthin has bright color and strong coloring power. It has unique health functions such as improving human immunity, delaying cell and body aging, preventing cancer and losing weight, and has high safety. Widely used in food, beverage, medicine, cosmetics and other fields. [0003] Usually, the color value of capsanthin processed by solvent method is between 150 and 200, and the total content of carotenoids does not exceed 10% of the total weight, and the rest is fatty acid lipids, proteins, sugars, etc. in peppers. To a certain extent, it limits the wide application of capsanthin. Contents of the inv...
