Embodiment 1

[0012] The treatment process of the cottonseed embryo of the present invention is as follows: using the cottonseed embryo as raw material, leaching with acetone twice for dephenolization and oil immersion, putting the softened and dried cottonseed embryo into the extractor, using 69% Acetone solution is used for extraction, the solvent extraction temperature is 50°C, the volume ratio of cottonseed germ flakes to acetone solution is 1:1.5, and the leaching time is 180 minutes. After the cottonseed germ flakes are drained, they continue to be transported forward. The low-concentration acetone solution pumped into the rectification tower is rectified to obtain an acetone solution with a purity of 90%. The second degreasing extraction is carried out, and the cottonseed germ flakes are extracted again. Evaporate the mixture of the obtained acetone and cottonseed oil to obtain crude cottonseed oil; after cooling, pass it into the acetone turnover warehouse, add anthranilic acid with ...

Embodiment 2

[0014] The treatment process of the cottonseed embryo of the present invention is as follows: the cottonseed embryo is used as raw material, leached twice with acetone for dephenolization and oil immersion, the softened and dried cottonseed embryo is loaded into the extractor, and 79% of the cottonseed embryo is used Acetone solution is used for extraction, the solvent extraction temperature is 40°C, the volume ratio of cottonseed germ flakes to acetone solution is 1:1.1, and the leaching time is 140 minutes. The final cottonseed flakes are drained and continue to be transported forward. The low-concentration acetone solution pumped into the rectification tower is rectified to obtain an acetone solution with a purity of 92%. The second degreasing extraction is carried out, and the cottonseed flakes are leached again. , the mixed solution of the gained acetone and cottonseed oil is evaporated to obtain cottonseed crude oil; after cooling, it is passed into the acetone turnover w...

Embodiment 3

[0016] The treatment process of the cottonseed embryos of the present invention is as follows: taking the cottonseed embryos as raw materials, leaching twice with acetone for dephenolization and oil immersion, putting the softened and dried cottonseed embryos into the extractor, using 88% Acetone solution is used for extraction, the solvent extraction temperature is 25°C, the volume ratio of cottonseed germ flakes to acetone solution is 1:2, and the leaching time is 50 minutes. The final cottonseed flakes are drained and continue to be transported forward. The low-concentration acetone solution pumped into the rectification tower is rectified to obtain an acetone solution with a purity of 98%. The second degreasing extraction is carried out, and the cottonseed flakes are leached again. , the mixed solution of the gained acetone and cottonseed oil is evaporated to obtain cottonseed crude oil; after cooling, it is passed into the acetone turnover warehouse, and the waste liquid d...

Abstract

A process for treating the cotton seed embryo flakes to obtain cotton seed protein used for feed and edible oil includes such steps as extracting from the cotton seed embryo flakes in acetone, rectifying the liquid extract, evaporating to obtain gross cotton seed oil and gossypol anthranilate, cooling the liquid extract, deoiling the cotton seed embryo flakes, continuous vacuum drying to obtain cotton seed protein used to prepared feed, and refining said gross oil to obtain class-two edible oil.

Description

technical field [0001] The invention relates to a treatment process of cottonseed germ, in particular to a process for producing cottonseed protein at low temperature by using cottonseed germ. Background technique [0002] As we all know, my country is a big cotton-producing country, and the cottonseed meal obtained after the cottonseeds are husked and screened to make oil, has restricted its use and dosage because it contains a toxic substance - gossypol. Cotton meal containing gossypol can only be used as low-grade feed or fertilizer, and its use is limited. The content of cottonseed protein after dephenolization is more than 50% (the first grade soybean meal content is 44%), and its main quality index is similar to that of soybean protein. It can completely replace soybean protein and be used in feed, food, biological fermentation and other industries. It has a wide range of uses. Cottonseed protein is a bean protein, which has the characteristics of low fiber, high meta...
