摘要

Subcritical water treatment of cereal residues including okara, defatted rice bran, desalted soy sauce lees, sake lees, corn kernel hull, and defatted rapeseed was conducted at 260℃ for 5 min to obtain the antioxidative extracts. The antioxidative activities of the extracts were evaluated using DPPH radical, peroxyl radical, hydroxyl radical, hypochlorite ion, and peroxynitrite ion. The results show that the extracts from the sake lees, corn kernel hull, and defatted rapeseed had differently the antioxidative activities against all radicals and ions. However, the okara, defatted rice bran and desalted soy sauce lees had no activity against the hypochlorite ion.
