(CN104693834B) 1. One method for producing fruit pigment persimon, characterized in, including the steps of: 1) the feedstock processing: will persimon cleaning, crushing; 2) high-pressure micro jet micronization processing: will be crushed persimon, in accordance with 1:5-6 the weight ratio of purified water was added, with a high shear emulsifier processing 10-20min, a rotational speed of 8000-12000r/min, and then processed using a high pressure jet superfine grinding device for 25 Ć, the treatment pressure is 80-120 mpa, processing times of 2-3 times, to yield a cream slurry; 3) fermentation: the step 2) to obtain a paste-like slurry the ultra-high instantaneous sterilization, and then adjusting pH 6.5-7.0, in volume percent to 10-15% of lactic acid bacteria culture fluid species mature access, into the fermenter fermentation, the fermentation temperature at 35-37 Ć, fermentation time 3-4h; 4) extraction: step 3) obtained by the ultra-high instantaneous sterilization fermentation broth, with an equal volume of ethyl acetate was repeatedly extracted from the fermentation broth, the aqueous layer, inacuo to remove ethyl acetate, ethyl acetate layer was repeated several times until a colorless; 5) a macro porous resin absorption purification: selected HP-20 macro porous resin, a method of a wet pretreated column, pH 3.5 with dilute hydrochloric acid to su liquid toner, with a constant flow pump control pigment solution through adsorption column, to be out of the liquid absorbance of the sample liquid was stopped after 10% absorbance was on the pigment solution, washed with pure water several times to wash the resin surface, 90% of the mass fraction of from 3.5 to pH of the solution to ethanol as eluent to pigment solution, liquid vacuum concentrated to remove ethanol the obtained dye, the dye solution to obtain a preliminarily purified; 6) polyamide column adsorption purification: polyamide pretreated wet column packed, step 5) to obtain pigment solution was passed through a preliminary purification polyamide column, mass fraction of from 50% to 0.1% of the mass fractions of methanol and formic acid are mixed solution as the eluent, collecting the colored portion, the eluent was concentrated in vacuo; 7) Sephadexs column purification: Sephadexs pretreated wet column packed, step 6) to obtain a purified sample of over Sephadex column, 50% by mass fraction of 0.1% formic acid in methanol and the mass fractions of mixed solution as the eluent, collecting the colored portion, the eluent was concentrated in vacuo; 8) preparative liquid chromatography separation and refinement: using preparative liquid chromatography separation and purification after the concentration of the pigment solution, to obtain persimon fruit pigment solution; 9) dry: freeze-dried, removing an aqueous pigment solution, to obtain persimon fruit pigment.
