Abstract :In the present study, high-performance liquid chromatography insert ignore into journalissuearticles values(HPLC); was used for the separation of tocopherols and triglycerides of processed soybean oil and deodorizer distillate insert ignore into journalissuearticles values(DD);. The results of normal and reversed-phase modes of HPLC revealed that concentrations of tocopherols and triglycerides content were decreased during the neutralization, bleaching, and deodorization processes. The loss of individual tocopherols ranged between 55.16% and 63.25%. During processing, triglycerides containing stearic-oleic-linoleic insert ignore into journalissuearticles values(SOL); moieties and palmitic-palmitic-linoleic insert ignore into journalissuearticles values(PPL); fragments showed greater reduction up to 38.14% and 37.69%, respectively. Among tocopherols and triglycerides; gamma-tocopherol and oleic-oleic-oleic insert ignore into journalissuearticles values(OOO); were found to be in greater concentrations 5.53% and 19.78%, respectively in DD as compared to their counterparts. A maximum reduction of tocopherols was observed in the deodorization step. DD was found to be a rich source of bioactive components; therefore, it could be used for many industrial applications including pharmaceutical formulations, cosmetics, and food industries.
