Abstract

The invention discloses a preparation method of a water-soluble paprika red pigment. The preparation method comprises the following steps: adding equal amount of a solution prepared from alkali and alcohol in proportion to an oil-soluble paprika red pigment serving as a raw material, performing saponification under constant-temperature stirring condition; adding an alcohol solvent, stirring, cooling to room temperature, performing centrifugal separation, reducing pressure of a liquid supernatant, heating and distilling the liquid supernatant, recycling alcohol to obtain an alcohol-soluble paprika red pigment; adding an emulsifying agent, mixing uniformly for emulsifying; adding water according to requirement and uniformly stirring to obtain the water-soluble paprika red pigment; dissolving undissolved substances in ethyl acetate, stirring, filtering, recycling ethyl acetate by performing reduced pressure distillation on a filter liquor, and extracting residual paprika red pigment. The use rate of the pigment is over 95 percent, the prepared water-soluble paprika red pigment is stable in performance, is of bright color and is transparent after being diluted, is short in process route, low in device cost, low in operation cost and convenient to store and transport, and can be put into industrialization easily.

Description

technical field [0001] The invention relates to a preparation method of water-soluble capsanthin. Background technique [0002] Capsanthin is a carotenoid pigment present in peppers, which is usually extracted from mature red pepper fruits. It is a non-toxic and safe natural pigment that can improve human immunity, delay cell and body aging, prevent It has unique health care functions such as cancer and weight loss, and is widely used in the coloring of various foods and medicines such as aquatic products, meat, cakes, salads, canned food, beverages, etc., and can also be used in the production of cosmetics. Capsanthin without special treatment is a deep red oil-soluble liquid with bright color and strong tinting power. It is only soluble in organic solvents such as oil or ethanol, and is difficult to dissolve in water, which greatly limits the application of capsanthin. Therefore, water-soluble capsanthin has become a hot topic in the deep processing of capsanthin. [000...
