Investigating the Recovery Potential of Protein and Antioxidant Compounds from Sesame Bran using Selected Basic Component Analyses

Ahmet Görgüç, Fatih Mehmet Yılmaz


Sesame bran is an industrial waste which is either not currently evaluated technologically or has limited use as animal feed. In this study, recovery potentials of protein and antioxidant compounds were investigated from three different sesame brans which are emerge as waste from dry and wet processing lines of the sesame - an intensively used input by roasted sesame seed, tahini and tahini halva plants especially in our country. In this context, protein extraction by alkaline method was conducted on brans obtained from three different processing lines (Dry line I, Dry line II and Wet line II). In addition, effects of aqueous solutions (70%, v/v) of acetone, ethanol and methanol on the extraction of phenolic compounds from sesame brans were investigated. Dry processing line sesame bran was found to have lower protein content than wet processing line bran; however, higher protein extraction yield was obtained by dry processing line bran. Phenolic compound extracts of dry and wet processing line sesame brans were found to have higher total phenolic content and antioxidant capacity values (DPPH and ABTS assays) than protein extracts obtained by alkaline method. It was determined that the most effective solvent for the extraction of phenolic compounds from sesame bran was 70% acetone solution; and the results of the ethanol and methanol extracts used as solvents were not significantly different.
