Abstract
Summary The effects of different grilling temperatures (220 °C, 250 °C, 280 °C, 310 °C) reaching the central temperature of 70 °C on heterocyclic amines (HAs) formation, moisture content, cooking loss, texture, colour, and sensory properties of grilled grass carp (Ctenopharyngodon idella) were investigated. The grilling condition significantly ( P < 0.05) affected cooking loss, moisture content, heterocyclic amines (HAs) formation, texture, colour and sensory properties. The results showed that 5 kinds of free and 9 kinds of protein‐bound heterocyclic amines were detected. The total amount of protein‐bound heterocyclic amines was much higher than that of the free state. Harman and Norharman, belonging to β‐carboline, constituted over 80% of the total content of heterocyclic amines. Considering the HAs formation and quality attributes, when the grilling condition was 280 °C for 10 min, the total content of HAs was the lowest, and the fish had moderate moisture content, firm texture, bright colour, and high sensory evaluation score.
