Abstract

The invention discloses a processing method for improving the quality of capsanthin, and relates to a preparation method of a natural pigment. A low-phospholipid-content freshwater shrimp acid material solution is used as an entrainer, the phospholipid in a capsanthin raw material is extracted by using supercritical carbon dioxide to prepare the high-quality capsanthin finished product. The preparation method comprises the following steps: preparing the capsanthin raw material, performing extracting with rapeseed oil, performing flash evaporation and reduced pressure residue removal, adding a low-phospholipid-content freshwater shrimp acid material, performing supercritical carbon dioxide extraction, performing separation, and obtaining the capsanthin finished product and a high-phospholipid-content freshwater shrimp acid material. According to the technical scheme, the low-phospholipid-content freshwater shrimp acid material solution is selected as the entrainer, the content of phospholipid in the capsanthin can be effectively reduced, and the finished product of the capsanthin has a color value of 256-310, the obtained high-phospholipid-content freshwater shrimp acid material can be used for preparing shrimp oil with high phospholipid content and the reutilization of phospholipid can be achieved.

Description

technical field [0001] The invention relates to a preparation method of natural pigment, in particular to a processing method for improving the quality of capsanthin. Background technique [0002] Capsicum red pigment has bright color, good coloring effect, and has certain health care function, so it has broad development prospects. Capsanthin is a tetraterpenoid orange-red natural plant pigment extracted from peppers, including red components (mainly capsanthin and capsanthin) and yellow components (mainly β-carotene and corn Xanthin), easily soluble in organic solvents such as acetone, ethyl acetate, No. 6 light gasoline, soluble in vegetable oils such as edible oil and rapeseed oil, and insoluble in water. [0003] The current main process is to use single or mixed solvents such as n-hexane, alcohol, acetone, ether, etc. to extract the mixture of capsanthin and capsaicin from red peppers to form a mixed oil, and then recover the solvent by a concentrated method to obtain...
