Abstract
This study was carried out to use the seashells and sand powders as natural bleaching material to reduce the color of crude soybean oil and compared with synthetic bleaching earth (clay) during their refining process, furthermore study some chemical properties (acid, peroxide and thiobarbituric acid values) of crude soybean oils. In the present study, the color of crude soybean oils under investigation was determined using Lovibond Tintometer (model F) and the percentage of removal of red color were calculated. The results showed that removal of the red color of crude soybean oils treated with seashells and sand powders were higher than bleaching earth and the highest removal was observed with crude soybean oil treated with seashell powder. Observational studies have demonstrated that additives seashells and sand powders to soybean oils as natural bleaching earth during their bleaching process retarded the red color of these oils compared with synthetic bleaching earth (clay) additional seashells and sand powders enhanced the acid, peroxide and thiobarbituric acid values of crude soybean oils.Biography
