Abstract: The research aimed to study the correlation between the sensory evaluation results of cottonseed meal and the chemical test results of its nutritional components and provide theoretical basis for the sensory detection in the production.Six kinds of cottonseed meal from different factories of different areas were collected to determine the contents of crude protein,free gossypol,NDF,ADF,ADL.The results showed that the content of free gossypol in six kinds of cottonseed meal was below the international allowable range and the colour and luster of cottonseed meal had certain correlation with the content of free gossypol.The test results showed that red cottonseed meal had higher content of free gossypol.The content of cotton hull was the main cause that affected the content of crude protein in cottonseed meal,showing an obvious negative correlation.The content of cotton hull and cotton wool showed a positive correlation with the fiber content.Too higher content of cotton hull and cotton wool would affect the quality of cottonseed meal.
