Zusammenfassung:	The invention relates to a method for degrading gossypol in cottonseed oil. The method comprises the following steps: putting cottonseed crude oil which contains the gossypol in a hydraulic cavitation device; carrying out hydraulic cavitation processing on the cottonseed crude oil through circulation, wherein the hydraulic cavitation device comprises a cavitator, and process conditions for carrying out cavitation degradation on the cottonseed crude oil are as follows: inlet pressure is 0.1-0.3MPa, the processing temperature of the cottonseed crude oil is 25-35DEG C, processing time is 2-6h, and flow is controlled to 15-60L/min. The hydraulic cavitation technology is used for degrading the gossypol in the cottonseed oil, and the gossypol can be effectively degraded in the cottonseed oil through the cavitation processing. The method has the advantages of low processing cost and simpleness in operation, does not affect the nutrition ingredients of the cottonseed oil and can guarantee food safety. The highest deg
