    Degumming, alkali refining, bleaching and quality of five genotypes of Jatropha curcas seed oils
    (CCSHAU, 2006) Duhan, Anil; Khabiruddin, Mohammad
    Jatropha curcas can be considered as major non-traditional oil yielding crop, which can grow in adverse climatic conditions. Its seed oil has high commercial importance because of its use as biofuel. Being having good nutritional profile, its oil and defatted seed cake can also be used for edible purpose, after removal of toxic constituents. Before and after refining, different physico-chemical parameters i.e. oil yield, free fatty acid, iodine value, peroxide value, carotenoids value, saponification value, unsaponifiable matter, fatty acid composition, protein in defatted cake and lecithin in oils of five genotypes viz. Hansraj, Urly Kanchan, SKN (Big), Chattarpati and JH-1 (Hisar local) of J. curcas were examined and compared with edible oils of soybean (var. PK-416), sunflower (var. HSFH-848) and groundnut (var. MH-4). It was observed that after refining, different physico-chemical parameters of the various genotypes of J. curcas oils were improved and found comparable with the changes in soybean, sunflower and groundnut oils. The result shows that the refined J. curcas oil have comparable edible utility with that of soybean, sunflower and groundnut oils, but have high potential to be use as biofuel in comparision to soybean, sunflower and groundnut oils.
