Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the examples. The method for producing low-temperature cotton meal by detoxification of cottonseed germ slices of the present invention uses cottonseed germ slices as raw material, followed by methanol leaching process and No. 4 solvent leaching process, methanol leaching process Obtain methanol leaching liquid, and No. 4 solvent leaching process obtains No. 4 solvent leaching liquid and wet meal. The wet meal is desolvated to obtain No. 4 solvent and low-temperature cotton meal. The temperature during desolventization is 50°C and the pressure is -0.05MPa.

[0011] The methanol leaching process refers to: the cottonseed germ slices are added to the extractor, soaked in methanol, the extractor discharges the methanol leaching solution and wet meal, the wet meal is desolvated to obtain dry meal, and methanol is recovered, and the dry meal enters No. 4 Solvent leaching process, the temperatu...

Abstract

The invention discloses a low-cost method for detoxifying cottonseed embryo sheets to produce low-temperature cottonseed meal. The cottonseed embryo sheets are used as raw material, a methanol leaching process and a No.4 solvent leaching process are performed successively, a methanol leaching liquid is obtained in the methanol leaching process, a No.4 solvent leaching liquid and wet meal are obtained in the No.4 solvent leaching process, the wet meal is desolvated to obtain a No.4 solvent and low-temperature cottonseed meal, and during desolvation, the temperature is not higher than 60 DEG C,and the pressure is -0.01 to -0.095 MPa. Because the leaching solvent methanol and the No.4 solvent are advantageous to oil leaching and subsequent extraction of gossypol and edible proteins, the extraction rate is high and the solvent is easy to recover, the preparation process is simplified and the cost is reduced. Especially, the No.4 solvent has low boiling point and low desolvation temperature, low-temperature cottonseed meal can be produced, protein denaturation cannot be easily caused and little effect exists on protein solubility. The method can produce the edible proteins and has highextraction rate.

Description

technical field [0001] The invention relates to the technical field of detoxification of cottonseed germ slices, in particular to a low-cost method for detoxifying cottonseed germ slices to produce low-temperature cotton meal. Background technique [0002] Cottonseed flakes contain cottonseed oil, protein and gossypol. Because gossypol is poisonous, it is necessary to remove gossypol during the protein extraction process. In the process of removing phenols, it is easy to cause protein denaturation, and it is impossible to extract edible protein. In the existing method for removing gossypol from cottonseed kernels, cottonseed kernel raw embryos use ethanol-hexane to leach gossypol and cottonseed oil in a ring extractor to obtain dopedol wet meal, and use a flash type steam flow precipitation drying device to extract gossypol and cottonseed oil The desolventization process combined with the horizontal dryer desolventizes and dries the dolcetol wet meal to obtain dolcetol meal...
