Abstract

The invention provides a method for producing gardenia yellow pigment, which comprises the following steps of: crushing gardenia fruits, extracting the gardenia fruit powder by using aliphatic hydrocarbon, then filtering the extract, and collecting filter residue; extracting the filter residue by using ethanol solution, and performing vacuum concentration on the extracted solution to obtain firstpigment concentrated solution; diluting the first pigment concentrated solution by using deionized water, performing primary purification by using macroporous resin, and then treating the solution byusing deionized water and ethanol solution as eluent and using an aqueous solvent as extrication solution in turn to obtain extrication solution containing pigment, and performing vacuum concentration on the extrication solution containing the pigment to obtain second pigment concentrated solution; and diluting the second pigment concentrated solution by using the deionized water, then performingsecondary purification by using chromatography resin, and treating the solution by using an aqueous solvent as a mobile phase to obtain the gardenia yellow pigment. The gardenia yellow pigment prepared by adopting the method has lower bitter and odor, and has wider application range.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicines, in particular to a production method of gardenia yellow pigment. Background technique [0002] Gardenia yellow pigment, also known as crocin, is a rare water-soluble carotenoid obtained by extracting, separating and drying the fruit of Rubiaceae gardenia, and is a natural food coloring. Gardenia xanthin has excellent resistance to reduction and microbial resistance, and has a good dyeing effect on starch and protein; at the same time, gardenia xanthin is easily absorbed by the human body and can be converted into vitamin A in the human body. Therefore, Gardenia yellow pigment is a nutritional natural plant pigment. [0003] In the existing production method of gardenia yellow pigment, the original medicinal material of gardenia jasminoides is usually pulverized, followed by degreasing, extracting, filtering, concentrating and purifying in order to obtain gardenia yellow pigment with ...
