Effects of adsorbents on benzo(a)pyrene, sesamol, and sesamolin contents and volatile component profiles in sesame oil

Abstract

Effects of adsorbent treatments used for reduction of benzo(a)pyrene (BaP) levels in volatile profiles and sesamol and sesamolin antioxidant contents in sesame oil were evaluated. Charcoal-based activated carbons with different mesh sizes and celite were used as adsorbents. Treatment with activated carbons led to reductions in BaP contents of sesame oil. A small charcoal-based activated carbon particle size was more effective for removal of BaP. Celite; however, did not show an effect on the BaP content of sesame oil under the experimental conditions. Volatile profiles of sesame oil were not influenced by addition of any adsorbent, and the sesamol and sesamolin contents were reduced by all adsorbents.
