A study on oil and other chemical composition of seeds for some commercial and brown colored Egyptian cottons
Abstract: This study was conducted to evaluate the physical and chemical properties of oil and some other chemical constituents of seeds in commercial and naturally brown colored Egyptian cottonseeds such as protein, gossypol, ash and moisture contents. The study also covered the determination of refractive index (RI), saponification value (SV), iodine value (IV) and the fatty acids profiles of cottonseed oils. The results revealed that brown cottonseed had lower values of oil content, protein content, refractive index, iodine value and linoleic acid percent. While it had highest gossypol content (5.33%) compared with the while verities. Giza 45 is consider the best Egyptian cotton verities in seed oil content. The data also, clearly revealed that the chemical composition mostly differed significantly among the varieties, especially regarding the seed oil % the average ranged between 16.4% to 24.22%. Also, the results showed that refractive index and saponification values of cottonseeds oil (CSO) had values which were very close to each other. Since, the iodine values (gI2/g oil) ranged from 10585 to 116.62 for the oil of brown cotton and Giza 85 variety respectively, which indicates that the oil of the Egyptian cottonseed belongs to the semi-dry oil of category.
