Abstract

The invention discloses a cottonseed protein production technology. The technology comprises the following steps: degreasing unexpanded cotton embryos through 6# solvent oil, carrying out low temperature drying, and processing the dried cotton embryos through a bulking machine to obtain expanded cotton embryos; and carrying out methanol solvent gossypol removal treatment on the expanded cotton embryos, centrifuging the phenol removed cotton embryos, and drying the centrifuged cotton embryos at a temperature of 150DEG C or less to obtain finished cottonseed proteins. The production technology has the advantages of simplicity, less loss, small energy consumption and low cost, obtaining of the high-quality cottonseed proteins with the free gossypol content being smaller than 400ppm and the protein solubility being greater than 55%, and easy realization of continuous industrial production.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a cottonseed protein production process. Background technique [0002] In the process of vegetable oil production, pressing and leaching methods are often used to extract oil. Oil extraction by leaching has the characteristics of low residual oil in meal, good quality of meal, low production cost and suitable for large-scale production. The use of gossypol in cottonseed processing affects the use of gossypol. Gossypol is a toxic substance in gossypol. If gossypol with high content of gossypol is used to make feed, livestock will be poisoned after eating it. The current cottonseed protein production process requires detoxification. The wet meal that has been detoxified by solvents is mostly dried by heating and evaporation to prepare finished protein. Puffing is a process operation of high temperature, high pressure and high shear. During th...
