Studies on Applied Property of Antioxidant Extracted from Kaempferi Galanga L.

Abstract

Abstract: Antioxidantextractedfrom Kaempferigalanga L.(AOKGL)showedstrong antioxidative activity inlard peanutoilandfishoil,whichwascon centrationdependent.Theaddition of0.02%ω(AOKGL)couldmakethelard rancidity time 2times longer.The an tioxidative activity in lard by addi ng 0.06%ω(AOKGL)was about the same as that ofω(BHT)=0.02%.Both citrate and ethylenedi amine tetraacetic acid showed marked synergic antiox-idativeactivityforAOKGLinlard.H enceAOKGLwas capabletoinhibitoxidationofalrdwithFe 3+≤310 -6 .

Key words: antioxidant from Kaempferi galanga L.(AOKGL), antioxidative, synergism
