Abstract
The invention relates to a method for extracting raffinose from cottonseed meal, including following steps: removing the cottonseed rind to get cottonseed kernel, softing the embryo of the cottonseed kernel, dipping the cottonseed oil with solvent-extracted oil, getting cotton dregs; adding 40-100wt.% of carbinol in the cotton dregs, dipping for 20-60 minutes at 0-70 DEG C, after removing the carbinol, getting coarse raffinose; dissolving the coarse raffinose by water or rare acid, controlling temperature at 0-100 DEG C, pH=2-7, filtering, decoloring, concentrating, crystallize, drying, getting extractive raffinose. The invention re-exacts the raffinose after degreasing, ensures to attain the raffinose as well as perfect conttonseed oil, and reduces the dissociative gossypol content in the cotton dregs and improves the cotton dreg quality.
Description
(1) technical field
The invention discloses a kind of preparation method of raffinose, particularly a kind of method of in cottonseed meal, extracting raffinose.
(2) background technology
Existing cotton dregs generally only extract Oleum Gossypii semen, and raffinose, the gossypol of part arranged in the cotton dregs, and the cotton dregs quality is not high.
(3) summary of the invention
The present invention provides a kind of method of extracting raffinose in cottonseed meal in order to overcome the deficiency of above technology, and the one, extracted useful material raffinose, the 2nd, removed deleterious gossypol, improved the quality of cotton dregs.
The present invention realizes by following measure:
The present invention relates to a kind of method of in cottonseed meal, extracting raffinose, it is characterized in that adopting following steps:
(1) get cotton benevolence after cottonseed is peeled off, cotton benevolence is softening rolls embryo, leaches Oleum Gossypii semen with solvent oil, gets cotton dregs;
(2) adding concentration expressed in percentage by weight in the cotton dregs is the methyl alcohol of 40-100%, and leaching is 20-60 minute under 0-70 ℃ of condition, behind the separating methanol, gets the raffinose coarse fodder;
(3) raffinose coarse fodder water or diluted acid dissolve, and controlled temperature 0-100 ℃, PH=2-7 filters, and decolouring concentrates, crystallization, and oven dry gets the elaboration raffinose.
The method of the extraction raffinose of the invention described above, the concentration of described methyl alcohol are 85-98%, and leaching temperature is 40-60 ℃, and leaching time is 20-40 minute.
Operational path is as follows:
The clear seed of high-quality cottonseed-wind-force-peel off-screen-cotton benevolence-soften-rolling embryo-oven dry-6# solvent oil leaching Oleum Gossypii semen-methanol solution leaches raffinose-separating methanol-raffinose coarse fodder-dissolving-cooling-filtration-raffinose solution-decolouring-concentrated-crystallization-oven dry-crushing packing-elaboration raffinose.
The invention has the beneficial effects as follows, carry raffinose after the first degreasing again, obtain raffinose when guaranteeing to obtain high-quality cottonseed oil, and reduce the content of free gossypol in the cotton dregs, improve the quality of cotton dregs.
(4) description of drawings
Fig. 1 is pretreatment technology flow line figure of the present invention
Fig. 2 is extract technology flow line figure of the present invention
(5) embodiment
With the case of handling 150 tons of high-quality cottonseeds day extracting method of the present invention is made specific description below.
The Oleum Gossypii semen yield is 15-20%, and dephenolize cotton dregs yield is 37-42%, and raffinose coarse fodder yield is 0.5-1.0%, elaboration raffinose yield 0.3-0.8%.
Per diem handle 150 tons of high-quality cottonseeds, get Oleum Gossypii semen 22.5-30 ton, get dephenolize cotton dregs 55.5-63 ton, get raffinose coarse fodder 0.75-1.50 ton, get elaboration raffinose 0.45-1.2 ton
Extraction step is divided into the pre-treatment of cottonseed, leaches, and is refining.
One. pre-treatment
Technical process as shown in Figure 1, pretreated Technology requires as follows:
