The effects of different cooking temperatures (65, 75, and 85 °C) and cooking levels (medium and well) on some quality properties, the formation of heterocyclic aromatic amines (HCAs), and the migration level of bisphenol-A (BPA) in trout fillets cooked by sous-vide were investigated. As a result, as expected, cooking caused a reduction in water content of the samples, whereas pH, TBARS, L*, and b* values increased. Cooking loss values ranged between 14.78 and 20.51%. Whereas IQ, MeIQ, 7,8-DiMeIQx, 4,8-DiMeIQx, PhIP, AαC and MeAαC could not be detected in the analyzed samples, varying levels of IQx (up to 0.16 ng/g) and MeIQx (up to 5.66 ng/g) were detected. It was determined that total HCA amounts ranged between 1.28 and 5.75 ng/g, and all or a big part of the total HCAs belonged to MeIQx. In addition, the migration level of BPA in sous-vide-cooked samples ranged between 4.93 and 27.11 ng/g.
