Antioxidant efficacy of methanolic extracts of peanut hulls in soybean and peanut oils

  • Published:
Journal of the American Oil Chemists' Society

Abstract

Antioxidant activity of methanolic extracts of peanut hulls (MEPH) was evaluated in soybean and peanut oils after accelerated oxidation at 60°C. Results showed that the oils with 0.12, 0.48, and 1.20% MEPH had significantly (P<0.05) lower peroxide values and acid values than the control after storage at 60°C. Moreover, oils with 0.48 and 1.20% MEPH were significantly (P<0.05) superior to 0.02% butylated hydroxyanisole (BHA) in reducing oxidation of both oils. Negative synergism was observed when 0.48 and 1.20% MEPH were mixed with 0.01% dl-α-tocopherol or 0.01% BHA in soybean oil compared to MEPH alone.
