Abstract
The invention discloses an extraction method for pigment of Chrysanthemum Anthocyanidin; fresh Chrysanthemum Anthocyanidinis used as main raw material, and then the pigment is prepared through steps of crushing, immersing with distilled water, leaching, combining filtrates, extracting with diethyl ether, layering, concentrating under reduced pressure, extracting, and drying at constant temperature. According the invention, process flows are simple; cost is low; and the extracted pigment is natural pigment, so that pigment is featured with natural color and good dyeing property, and is mainly used as colorants for beverages, sweets, jams, cakes and so on.
Description
Technical field
The invention belongs to field of fine chemical, relate to a kind of process for extracting of pigment, be specifically related to a kind of process for extracting of four seasons chrysanthemum pigment.
Background technology
Food dye is a kind of of pigment, is to make food change the foodstuff additive of original color to a certain extent.Food dye is divided into two kinds of natural and synthetic; Natural food colour is the pigment that directly from animal vegetable tissue, extracts, and is harmless, synthetic food color; Be to use the aniline dyestuff of separating in the coal tar to process as raw material; The pigment of these synthetic is because of being prone to bring out poisoning, diarrhea even cancer, and is harmful, so can not use more or need not as far as possible.Yellow pigment is a kind of in the natural pigment, and the extraction process of existing four seasons chrysanthemum pigment is complicated, and cost is higher, and the pigment performance of extraction is stable inadequately, and color and luster is dim.
Summary of the invention
Goal of the invention: the present invention provides the process for extracting of a kind of extraction process a kind of four seasons chrysanthemum pigment simple, with low cost in order to solve the deficiency of prior art, and the pigment color and luster of extraction is natural, tint permanence is good.
The technical scheme that the present invention adopts: a kind of process for extracting of four seasons chrysanthemum pigment, said four seasons chrysanthemum pigment extract concrete steps and comprise:
(1) 100-110 part exsiccant four seasons chrysanthemum is pulverized, the dry powder of gained was with 150-160 part zero(ppm) water soaking at room temperature 3-4 hour;
(2) carry out suction filtration after the immersion, filter residue extracted twice in 2-3 hour again with 100-120 part distilled water immersion, merging filtrate behind the suction filtration;
(3) the gained extracting solution uses 30-40 part ether with extracted with diethyl ether 3 times at every turn, discards ether layer after the extraction; Combining water layer, the gained water layer carries out underpressure distillation at 1.30～1.40KPa, gets yellow medicinal extract; At 40-50 ℃ of freeze-day with constant temperature 2-3 hour, the gained powder was four seasons chrysanthemum pigment again.
Beneficial effect: technical process of the present invention is simple, and is with low cost, and the pigment of extraction is a natural pigment, the color and luster nature, and tint permanence is good, mainly is used as the tinting material of beverage, candy, jam and cake etc.
