Tertiary butylhydroquinone as antioxidant for crude sunflower seed oil

Abstract

Abstract This study indicates that crude sunflower seed oil is very susceptible to oxidation; thus prolonged storage should be avoided. Protection of the crude oil with a potent antioxidant such as tertiary butylhydroquinone (TBHQ) would seem both practical and beneficial. Discoloration which develops in the crude oil with or without TBHQ can be removed by proper selection of bleaching materials. Additional benefits to be derived from using TBHQ should be investigated by using test methods designed to study subtle flavor qualities of deodorized oils.
