Abstract:The changes of acid value, polar substances content and fatty acid composition of soybean oil with different dosages of feruloylphenethylamine (FRP) and feruloyltyramine (FTP) during frying in soybean oil were compared, and the antioxidation properties of FRP and FTP were studied in frying system. The results showed that the soybean oil added with FRP or FTP with dosage 500 mg/kg had the best antioxidation property, which could effectively inhibit the increase of acid value, polar substances content and the oxidative degradation of linoleic acid and linolenic acid in frying oil. |
