Abstract
The antioxidant activity of 5-caffeoylquinic acid on soybean oil in th e presence of phytic acid at concentration ranges of 50-400 mg/kg oil or citric acid at 200 mg/kg oil was investigated The oil was stored at 55 degrees C for 6 d and monitored by peroxide and conjugated diene m easurements. Both citric and phytic acids do not appear to provide any synergistic effects with 5-caffeoylquinic acid. The results showed th at 5-caffeoylquinic acid may act both as primary antioxidant and metal chelator. (C) 1998 Academic Press Limited.
