To investigate the effect of pretreatment methods on the formation of advanced glycation end products(AGEs)in air-fried fish cakes.Fish cakes were prepared from frozen silver carp surimi,and the fish cakes in the experimental group were treated with three pretreatment methods(pre-frying,pre-frying+freezing,and pre-frying with coating)be-fore air frying,and the direct air-fried fish cake was the control group.The AGEs contents,physicochemical indicators and their correlations in the interior,surface and batter layer of air-fried fish cakes were analyzed.Compared with the samples of control group,the pre-frying and pre-frying+freezing significantly increased the oil absorption(83.83%and 203.48%)in the surface layer of fried fish cakes,which accelerated the Maillard and lipid oxidation reactions,leading to an increase of 120%~151%in CML content.On the contrary,the golden crust formed in the pre-frying with coating group reduced the oil absorption(72.63%and 60.00%)and water loss(3.87%and 0.70%)in the interior and surface layer of the samples,and further decreased the generation of AGEs by weakening the lipid oxidation and the degradation of furosine.And the CEL content decreased by 59.32%.Correlation analysis showed that oxidation reaction and Maillard reaction had a positive correlation with the generation of AGEs in fish cake,and the highest correlation coefficient was found between lipid oxidation and AGEs content.In conclusion,the battered pre-frying not only improved the color of fried fish cakes but also decreased their AGEs contents via depressing the lipid oxidation and Maillard reaction.
