Determination of Gossypol Levels of Cottonseed Meal Produced in the Southeastern Anatolia Region

English (OpenAlex)

The levels of free and total gossypol and the raw nutrient content (crude protein, crude oil, dry matter, crude ash, neutral detergent fiber, and acid detergent fiber) in cottonseed meals that are produced in Southeastern Anatolia were determined in the present study. Gossypol and raw nutrient content analyses were carried out by using the cottonseed meal samples obtained from 12 different cottonseed oil factories located in Diyarbakır, Şanlıurfa, Adıyaman, Batman, Mardin, and Gaziantep. As a result of the present study, free gossypol levels in the cottonseed meal samples were 1937, 1878, 1916, 1845, 1442, and 1528 mg/kg, respectively. The free gossypol contents in the cottonseed meal samples obtained from Diyarbakır, Şanlıurfa, Adıyaman, and Batman provinces were statistically significantly higher when compared to samples obtained from Mardin and Gaziantep (p0.05), except for Gaziantep, where the samples had significantly lower oil and significantly higher protein content (p
