Cyclopropenoid Fatty Acid Content and Iodine Value of Crude Oils from Indian Cottonseed

Abstract

Cyclopropenoid fatty acid (CPFA) and iodine value (IV) of oils extracted from 30 varieties of cottonseed belonging to 4 botanical species, Gossypium arboreum, G. herbaceum, G. hirsutum and G. barbadense, have been reported. The CPFA determined by HBr titration method ranged from 0.66 to 1.51%. The IV of the oils ranged from 93.3 to 111.2. CPFA contents were significantly different among the species and nonsignificant within the species. The mean values of CPFA for different species were 0.67 (G. bar-badense), 0.83 (G. hirsutum), 1.14 (G. berbaceum) and 1.40% (G. arboreum). There was no correlation between IV and CPFA content. © 1982 American Oil Chemists' Society.
