主　　题：Vegetable oil Thermal treatment Minor lipid components Oxidative stability Maillard reaction 

摘      要：Oxidative deterioration of vegetable oils is of great importance in the food *** China,vegetable oils produced via thermal pretreatment are popular owing to their strong oil flavor and enhanced ***,we review:(i)the currently employed thermal treatment methods of oilseeds before oil extraction;(ii)effects of thermal treatments on the physicochemical properties,contents of minor lipid components,and oxidative stability of vegetable oils;and(iii)Maillard model systems that are related to oil and oilseed *** the thermal pretreatment technologies,microwave and infrared radiations are promising,but these are not performed on the same large production scales as *** most oilseeds,thermal treatments increase the yield of extracted oil and content of minor lipid compounds in the oil,such as polyphenols,tocopherols,and *** addition,some Maillard reaction products(MRPs)generated by heating oilseeds have been *** presence of both minor lipids and MRPs in the oil confers improved oxidative ***,the mechanism or relationship between thermal treatment and oxidative stability is yet to be clearly elucidated because vegetable oil oxidation is dependent on variables such as unsaturation,concentration and types of minor lipid components,MRPs,and the potential synergistic effects of these ***,several Maillard reaction models related to thermally treated oilseeds have been established,suggesting that MRPs play a critical role during ***,comprehensive identification of antioxidants and the mechanism by which they inhibit oxidation are *** research can be performed to establish models that would help elucidate the antioxidative mechanisms of MRPs for more *** these models,it will be possible to predict the oil quality after processing,based on the presence of MRPs and oil chemistry.
