Abstract
The present study evaluated the effect of chitosan coating enriched with clove oil on rainbow trout (Oncorhynchus mykiss) sensory changes during refrigerated storage at 4°C was done for a period of 15 days. Three different treatments were tested: C1 (control samples), C2 (chitosan coating) and C3 (chitosan + 1 % [v/w] clove EO added). Five experienced panelists, academic staff who were trained in sensory descriptors for cooked fishes, were employed to evaluate the quality of trout fillets during storage. Rainbow trout fillets were assessed on the basis of appearance, taste, texture and odour characteristics using a nine point descriptive scale. Panelists were asked to evaluate on a 5-point hedonic scale ranging from very poor (1) to very good (5) where: 1-very poor, 2-poor, 3-normal, 4-good and 5-very good. Sensory scores of each sample were at “good quality” after processing. Group C3 samples were assessed as the most acceptable products by the panellists.
