Title: Assessment For Protein And Oil Quality Of Seed Of Three Local Cottonseed Cultivars
Author: Abdelrahman, Reem Babiker Bashir
Abstract: This study aimed to assess protein and oil quality of three local cottonseed cultivars namely ( Barac 67 B , Barakat and Shambat ) . The study of chemical composition , the classical protein fractions : albumins, globulins, prolamins, glutelins and insoluble proteins, minerals content ( Ca, Mg , Fe , Cu , Zn , Mn , Co) and tannins content in the three cultivars was carried out . In addition, oil characteristics which involved physiochemical characteristics : refractive index , relative viscosity , color , peroxide value, acid value, saponification number and iodine number was carried out . The study showed that the crude protein is high in the three cultivars . The major proportion of protein in this plant seed is in the form of globulins, followed by albumins and lesser amounts of glutelins and prolamins. Globulin is the dominant fraction in the three cultivars especially in Shambat cultivar. Ca and Mg constitute the highest macro elements in the three cultivars. Followed by Fe and Cu in Barac , Zn and Mn in Barakat and Co in Shambat Cultivar . Tannin content is significantly high in Shambat cultivar. The physiochemical characteristics of oil seed cultivars compared well with other edible oils and with FAO /WHO standards.
