Abstract
The invention discloses a method of extracting tartaric acid by fermenting grape pips, and relates to the technical field of extraction methods. The method comprises the following steps: adding residual grape pips after juicing into tartaric acid fermentation bacteria (dissociants of Gluconoba-cter suboxydans); fermenting for 5-6 days at 30 DEG C; forming tartaric acid by oxygenolysis of glucose by way of 2,5-diketo-D-gluconic acid while forming hydroxyacetic acid, wherein the melting point of tartaric acid is 171-174 DEG C, and the melting point of hydroxyacetic acid is 78-79 DEG C. The tartaric acid is separated and purified according to great disparity of the melting points of tartaric acid and hydroxyacetic acid. The method disclosed by the invention is simple, convenient for actual operation, high in extraction rate and good in product purity, and has good economical benefit.
Description
Technical field
The present invention relates to extracting method technical field, be specifically related to a kind of tartaric method of Semen Vitis viniferae fermented extracted.
Background technology
Tartrate (tartaric acid), that is, 2,3 dihydroxybutanedioic acid, be a kind of carboxylic acid ﹐ be present in various plants ﹐ as grape and the sub-﹐ of Luo Wang be also one of organic acid main in grape wine.As the anti-oxygen agent ﹐ adding in food, can make food there is tart flavour.The purposes of tartrate maximum is drink additive.Also be pharmaceutical industries raw material.In mirror industry processed, tartrate is an important auxiliary agent and reductive agent, can control the formation speed of silver mirror, obtains the very coating of homogeneous.In the winestone that tartrate generally produces from wine making process, extract, yield poorly, efficiency is poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of extraction efficiency high, the tartaric method of the simple Semen Vitis viniferae fermented extracted of method.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of tartaric method of Semen Vitis viniferae fermented extracted, comprise following method, with the remaining Semen Vitis viniferae of squeezing the juice, add tartaric acid fermentation bacterium (dissociant of Gluconoba-cter suboxydans), at 30 ℃ of temperature bottom fermentation 5-6 days, by glucose oxidase, decompose, via 2,5-diketo-maltonic acid, when forming oxyacetic acid, form tartrate, its unresolvable tartaric acid fusing point is 171-174 ℃, oxyacetic acid fusing point is 78-79 ℃, according to both fusing point great disparity difference, carries out separating-purifying tartrate.
The invention has the beneficial effects as follows: the inventive method is simple, be convenient to actually operating, extraction yield is high, and good product purity has good economic benefit.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment 1
A kind of tartaric method of Semen Vitis viniferae fermented extracted, comprise following method, with the remaining Semen Vitis viniferae of squeezing the juice, add tartaric acid fermentation bacterium (dissociant of Gluconoba-cter suboxydans), at 30 ℃ of temperature bottom fermentation 5-6 days, by glucose oxidase, decompose, via 2,5-diketo-maltonic acid, when forming oxyacetic acid, form tartrate, its unresolvable tartaric acid fusing point is 171-174 ℃, oxyacetic acid fusing point is 78-79 ℃, according to both fusing point great disparity difference, carries out separating-purifying tartrate.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
