Abstract
The invention discloses an extraction method for melanin; black glutinous rice is as raw materials; ethanol is as an extracting agent; the extraction method comprises the following steps: adding the black glutinous rice into the ethanol and leaching repeatedly, then filtering, heating obtained filtrate with a water bath, distilling to recover the ethanol, and concentrating under reduced pressure residual liquid to paste, and evaporating with the water bath to obtain the finished products of the melanin. According to the invention, technologies are simple; operations are convenient; the prepared melanin is natural and nontoxic, and is featured with natural color, higher nutritional value, and functions of improving vision, activating blood, tonifying spleen and warming liver after the melanin is used forlong term.
Description
Technical field
The present invention relates to a kind of extraction method of natural pigments, be specifically related to a kind of melanic process for extracting.
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.Melanochrome is a kind of in the natural pigment, and existing melanic extraction process is complicated, and cost is higher.
Summary of the invention
Goal of the invention: the present invention provides the melanic process for extracting that a kind of technology is simple, cost is low in order to solve the deficiency of prior art, and is abundant with melanochrome color and luster nature, nutritive value that this method is extracted.
The technical scheme that the present invention adopts:
A kind of melanic process for extracting is characterized in that: the concrete steps that described melanochrome extracts are:
1) have whisking appliance and condensation reflux device there-necked flask in, add earlier clean, dried black glutinous rice 450-500 part, add ethanol 210-270 part ethanol again, be heated to 70-75 ℃ constantly stirring down, reflux and leached 1-2 hour;
2) leaching liquid is filtered, it is for use to filtrate, and filter residue is used 210-270 part ethanol set by step 1 again) repeat to leach twice;
3) merge three times filtrating, use heating in water bath,, raffinate is evaporated to the thick shape of cream under 70 ℃, use water bath method at last, promptly make melanochrome of the present invention through distillation recovery ethanol.
As preferably, described concentration of ethanol is 50%.
Beneficial effect: the present invention compared with prior art; Its remarkable advantage is: melanic process for extracting technology provided by the invention is simple, be convenient to operation; The melanochrome Nantural non-toxic of preparation, color and luster nature; Have high nutritive value, long-term eating can be played effects such as item invigorating blood circulation, strengthening spleen and warming liver.
