ANTIOXIDATIVE POTENTIAL OF SUBSTANCES CONTAINED IN COLD PRESSED SOYBEAN OIL AND AFTER EACH PHASE OF REFINING PROCESS

Abstract This study is an investigation of determining the changes of scavenger capacity of DPPH· free radicals through substances contained in soybean cold pressed oil and in oils taken after individual phases of refinement. The content of tocopherols and phenolic compounds was determined. Scavenging of DPPH· was examined and the coefficient of antiradical activity (AE) was counted in order to objectively determine the potential. Cold pressed oil had the highest ability of scavenging of DPPH·. This oil also possessed the largest coefficient of antiradical efficiency (AE = 14.51∙10-3). The largest quantity of tocopherols was observed in crude oil and phenolic compounds in cold pressed oil. It was affirmed that every next stage of refinement causes the decreasing of tocopherols and phenolic compounds content.
Keywords: Soybeans oil, tocopherols, free radical scavenging: DPPH·, antiradical efficiency, refining
