摘要

以土耳其Cukurova地区3个棉花基因型棉花绵(Gossypium hirsutum L.)、Cukurova 1518、PAUM 15和ba119为研究对象，对其油脂的游离脂肪酸、过氧化值、碘值、不皂化物、总类胡萝卜素和生育酚含量及脂肪酸组成等理化性质进行了研究。种子含油量为17.2 ~ 19.6%，其中pam 15为含油量最高的基因型。其他理化性质的范围及其数值如下:棉籽油中游离脂肪酸1.7 ~ 2.8%，过氧化值5.3 ~ 6.0 meq O2 kg-1，不皂化物2.1 ~ 2.3%，碘值102 ~ 110，总类胡萝卜素含量119 ~ 140 mg kg-1，总生育酚含量887 ~ 920 mg kg-1，亚油酸52.00 ~ 55.82%，棕榈酸24.85 ~ 25.63%，油酸14.06 ~ 17.00%，硬脂酸3.01 ~ 3.13%。与其他基因型相比，pam 15的含油量和品质特征最高，更适合作为食用油食用。

Physico-Chemical Characteristic and Fatty Acids Compositions of Cottonseed Oils

In this study, three cotton genotypes of species Gossypium hirsutum L., Cukurova 1518, PAUM 15 and BA 119 were investigated for their some physicochemical properties of oils such as free fatty acids, peroxide value, iodine value, unsaponifiable matter, total carotenoid and tocopherol contents and fatty acids composition in Cukurova region in Turkey. Seed oil content ranged 17.2-19.6% and PAUM 15 was found to be genotype with the highest oil content. The range of other physicochemical properties and their values are as follows; free fatty acids 1.7-2.8%, peroxide value 5.3- 6.0 meq O2 kg-1, unsaponifiable matters 2.1-2.3%, iodine value 102-110, total carotenoid content 119-140 mg kg-1, total tocopherol content 887-920 mg kg-1, linoleic acid 52.00-55.82%, palmitic acid 24.85-25.63%, oleic acid 14.06-17.00%, stearic acid 3.01-3.13% in the cottonseed oils. PAUM 15 was determined to be more suitable for food consumption as edible oil due to its highest oil content and quality characteristics than the others genotypes.
