665.0288 AOCS 7th ed. 2017-2019 rev. Ref.
Total gossypol defines gossypol and gossypol derivatives, both free and bound, in cottonseed products that are capable of reacting with 3-amino-1-propanol in dimethylformamide solution to form a diamino- propanol complex, which then reacts with aniline to form dianilinogossypol under the conditions of the test method. Gossypol, gossypol analogs and gossypol derivatives having an available aldehyde moiety are measured by the method. Applicable to crude cottonseed oil and cottonseed soap stock.
