Objective To explore the effects of curcumin and vitamin C supplementation on harmful substances heterocyclic amines (HAAs) and advanced glycation end products advanced glycation end products (AGEs) in Salmon salar roasting process inhibition and the effect of exogenous additives on the flavor of grilled Salmon salar. Methods The concentrations of HAAs and AGEs were determined by high performance liquid chromatography-tandem mass spectrometry, and the inhibitory mechanism of reducing sugar, creatine, creatinine, glyoxal and other precursors and lipid oxidation levels were further determined. The changes of volatile flavor of Salmon salar during baking were analyzed by gas chromatography and ion migration spectrometry. Results Compared with the control group, curcumin and vitamin C showed significant inhibitory effects on HAAs and AGEs (P˂0.05), and the total HAAs inhibition rates were 75.21% and 59.52%, respectively. The inhibition rates of Nε-carboxymethyl-lysine in AGEs were 90.56% and 90.87%, respectively. The inhibition rates of Nε-carboxymethl-lysine were 94.57% and 94.80%. The concentrations of precursors such as reducing sugar, creatine, creatinine and glyoxal were highly correlated with the content of HAAs and AGEs. In addition, volatile flavor analysis showed that the addition of curcumin and vitamin C had a certain effect on the flavor of grilled Salmon salar, and increased the concentration of aroma compounds such as 3-hydroxy-2-butanone, 2,6-dimethyl- 7-octene-2-ol and menthol, which contributed to the overall smell of Salmon salar. Conclusion Curcumin and vitamin C affect the key precursors and intermediates in the formation of HAAs and AGEs, and have a significant inhibitory effect. The development of this study provides theoretical guidance for the control of harmful substances in hot processing of fish products, and provides reference for optimizing the processing technology of fish products.
