In this study, the effects of chitosan extracted from Metapenaeus stebbingi shells on color properties of gilthead sea bream (Sparus aurata) during refrigerated storage (4±1ºC) were examined. The control and treated fillet samples were analyzed periodically for color (L*, a*, b*) analysis. Accordingly, it was determined that chitosan has a positive effect on L* and a* values of gilthead sea bream (p<0.05), while it displayed no effect on b* value (p>0.05). Any significant difference was not detected between chroma and hue values of groups (p>0.05)
