Crude vegetable oils contain triacylglycerols as major component and various minor components such as diacylglycerols, monoacylglycerols, free fatty acids, phospholipids, tocopherols, sterols, squalene, color pigments, waxes, aldehydes, ketones, triterpene alcohols and metals that may affect the quality of the final product. The minor components are removed partially or entirely by either physi...

This study describes a catalytic decomposition and crystallization process to recover phytosterols from the waste residue of soybean oil deodorizer distillate (WRSODD). Various solvents were used for the crystallization of phytosterols. The effect of different solvents on the purity and yield of recovered phytosterols was investigated. The composition of WRSODD was analyzed by silica gel column...

The vitamin E analogs δ-tocotrienol (DT3) and γ-tocotrienol (GT3) have significant protective and mitigative capacity against the detrimental effects of ionizing radiation (IR). However, the expense of purification limits their potential use. This study examined the tocotrienol-rich fraction of rice bran (TRFRB) isolated from rice bran deodorizer distillate, a rice oil refinement waste product,...
