Problems solved by technology

[0004] The problem that adopts above-mentioned technique to exist is: the material that methanol extracts except gossypol and sugars etc., still contains a large amount of crude lipids in protein material and has not been proposed; What adopt is single polar solvent alcohol solvent to carry out, Only anti-nutritional factors soluble in polar solvents can be extracted, and anti-nutrients and lipids soluble in non-polar solvents have no effect

Embodiment 1

[0025] Embodiment one: a kind of cottonseed protein production method that can extract multiple by-products, this production method comprises the following steps:

[0026] 1) The meal powder is stirred and extracted under the action of a solvent. The solvent is a mixed solvent of methanol solution and vegetable oil extraction solvent. The meal powder is obtained by crushing the cottonseed low-temperature cake to a particle size ≤ 3mm. The cottonseed low-temperature cake refers to the cottonseed leaching meal , crush the raw material to a particle size ≤ 3mm. The concentration of the methanol solution of the mixed solvent is 75-90%. The mixing ratio of methanol and vegetable oil extraction solvent in the mixed solvent is 8:2. The mixed solvent of this ratio is used for the extraction of one-time leaching meal, and the extraction temperature is 30- At 55°C, the ratio of meal to solvent or meal to mixed solvent is ≤0.25.

[0027] 2) After extraction, the material is separated fr...

Embodiment 2

[0037] 1) The meal powder is stirred and extracted under the action of a solvent. The solvent is a mixed solvent of methanol solution and vegetable oil extraction solvent. The meal powder is obtained by crushing the cottonseed low-temperature cake to a particle size ≤ 3mm. For the processed cottonseed cake, the raw material is crushed to a particle size of ≤3mm. The concentration of the methanol solution of the mixed solvent is 80%, and the mixing ratio of methanol and vegetable oil extraction solvent in the mixed solvent is 6:4. The mixed solvent of this ratio is used for the extraction of low-temperature machine pressed cake, and the extraction temperature is 30-55°C , the ratio of meal to solvent or meal to mixed solvent is ≤0.25.

[0038] 2) After the extraction, the material is separated from the mixed solution, and the wet meal is obtained after the material is drenched;

[0039] 3) Desolventizing the wet meal, further extruding the wet meal for desolventization, the mo...

Embodiment 3

[0049] 1) The meal powder is stirred and extracted under the action of a solvent. The solvent is a mixed solvent of methanol solution and vegetable oil extraction solvent. The meal powder is obtained by crushing the cottonseed low-temperature cake to a particle size ≤ 3mm. After processing the cottonseed cake, these raw materials are crushed to a particle size ≤ 3mm. The concentration of the methanol solution that configures the mixed solvent is 90%, and the mixing ratio of methanol and vegetable oil extraction solvent in the mixed solvent is 9:1. The mixed solvent of this ratio is used for the extraction of the meal after cottonseed low-temperature puffing and oil extraction. The extraction temperature is 30-55°C, the ratio of meal powder to solvent or meal meal to mixed solvent is ≤0.25.

[0050] 2) After extraction, the material is separated from the mixed solution, and the material is drenched to obtain wet meal;

[0051] 3) Desolventizing the wet meal, further extruding ...

Abstract

A cottonseed protein production method capable of extracting various by-products includes the steps: stirring and extracting meal powder under the action of solvents; separating materials from the solvents after extraction to obtain wet meal; desolventizing the wet meal; drying the wet meal at low temperature; adjusting the water content of the wet meal and continuing removing residual solvents to form a cottonseed protein concentrate product meeting requirements; separating the separated solvents to obtain methanol mixed liquid and cottonseed mixed oil containing solvents for vegetable oil extraction; continuing separating the methanol mixed liquid, recovering methanol and keeping the remaining, namely raw sugar and crude fat mixture; separating the raw sugar and crude fat mixture to obtain raw sugar substances and crude fat substances. The solvents are mixed solvents of methanol solution and the solvents for vegetable oil extraction. Cottonseed meal processed and produced at the low temperature serves as a raw material and can be extracted to obtain cottonseed protein concentrate and raw sugar, the raw fat substances with the yield exceeding raw sugar yield can be obtained, cottonseed oil can be further extracted, and residual oil in the meal is further reduced, so that the field of cottonseed processing has better economical efficiency.

Description

technical field [0001] The invention relates to the technical field of cottonseed processing, in particular to a method for producing cottonseed protein which can obtain concentrated cottonseed protein, crude sugar substances and crude lipid substances after processing. Background technique [0002] Cottonseed protein is a soy protein, which has the characteristics of low fiber, high metabolizable energy, high amino acid digestibility and good palatability, and is a high-quality edible protein. However, since cottonseed contains gossypol, and gossypol is a toxic substance, it has become the focus of the industry to completely remove phenols, increase the content of cottonseed protein after treatment, and reduce various sugars and other anti-nutritional factors remaining in cottonseed protein question. [0003] The invention patent application with the application number 201210483256.3 discloses a cottonseed treatment method. In this treatment method, the cottonseeds are ext...
