Annotation
The article deals with the technological scheme of refining cottonseed oil purified from gossypol. In the experiments, oil samples purified from gossypol containing monoethanolamine (MEA) were refined in two stages using sodium hydroxide. According to the research, the optimal temperature for the refining process was increased from 25 ℃ to 50-55 ℃ at the end of the process, the concentration of the alkaline solution was 200 g/l, and the amount of water supplied to moisten the soapstock was formed 0.5-1.0% by weight of oil. To completely purify the oil from gossypol and its derivatives, urea solutions with a concentration of 20-25% in the amount of 0.3-0.7% are given using capacity (5a) instead of water supplied in the process of alkaline refining. The results of the study showed that high gossypol cottonseed oil was treated with monoethanolamine in the amount of 0.2% by weight of oil, as well as when treated with urea solution in the amount of 0.5% by weight of oil for complete refining of gossypol refined oil, it has been found that positive results such as obtaining oils containing gossypol content of up to 0.002% can be achieved.
