Fresh rice bran which stored in a condition for different period was used as material to prepare rice bran glutelin after defatting,and effects of rice bran rancidity on the structure properties of rice bran glutelin were investigated.The results indicated that as storage time of fresh rice bran increased,rice bran glutelin carbonyl and disulfide content increased,and free sulphydryl content of rice bran glutelin decreased,which indicated that storage of rice bran led to oxidation of rice bran glutelin.As storage time of fresh rice bran increas...
