The aim of this study was to investigate the effect of chitosan and cooking methods (pan-frying and microwave) on the rate of heterocyclic aromatic amine compounds formation in the fillet of Beluga sturgeon. The experiment was designed in 6 treatments, including T1 (control without chitosan), T2 (fried treatment without chitosan), T3 (sample containing 1% acid soluble chitosan), T4 (fried sample containing 1% acid-soluble chitosan), T5 (sample cooked in microwave without chitosan) and T6 (sample cooked in microwave containing 1% acid-soluble chitosan). The use of acid-soluble chitosan (1%) had a significant effect on moisture content, pH and weight changes during cooking (P<0.05). In the cooked fillet, the HAAs values including PhIP (-5.68-Nd), IQ (-1.16-Nd), MeIQ (-1.66-Nd), and MeIQx (0.7-6.47) were detected. The inhibition rate of chitosan for the heterocyclic compounds in cooked fillet was 57.44 to 63.98%. The results showed that acid-soluble chitosan had a significant effect on cooking indices and reduced production of the heterocyclic aromatic amine compounds on cooked huso fillets.
