全脂低温脱酚棉籽蛋白生产实践

棉籽经过清理、剥壳、风选、调质、轧坯、干燥、脱酚等工段生产出全脂低温脱酚棉籽蛋白。该产品棉酚含量小于400 mg/kg, KOH蛋白质溶解度大于60%,蛋白含量不低于43%,是一种综合性价比较高的饲料原料,全过程低温处理保留了棉籽油的营养价值,较好地控制了KOH蛋白质溶解度;与传统棉籽蛋白相比,增强了产品的功能性、简化了生产工艺、降低了生产成本、提高企业市场竟争力。

Production practice of whole fat low temperaturedegossypoled cottonseed protein

The whole fat low temperature degossypoled cottonseed protein was produced from cottonseed by cleaning, decorticating, winnowing, conditioning, flaking, drying and degossypolization. The product was a comprehensive cost-effective feed material with gossypol content less than 400 mg/kg, protein solubility in KOH solution more than 60%, and the protein content not less than 43%.The nutritional value of the cottonseed oil was retained and the protein solubility in KOH solution was well controlled by the whole process low temperature treatment. Compared with the traditional cottonseed protein, it had advantages of enhancing the product functionality, simplifing the production process, reducing the production cost and increasing the market competitiveness of the enterprise.
