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.="">
