The effects of chitosan (Ch) (Medium molecular weight chitosan) coating combined with natamycin (Ch+ N) on quality of salted kutum (Rutilus frisii kutum) roe (treated with 4% NaCl salt) during refrigerated storage (4±1°C) were studied over a period of 90 days. A solution of Ch (1%, w/v) and Ch+ N (1%, w/v Ch +5 and 10 mg natamycin per Kg salted roe) was used for the coating. The control (salted roe) and the coated roe samples were analyzed periodically (0. 30, 60 and 90 days) for chemical (TVB-N, PV, TBA), remaining salt and pH characteristics. The results indicated that the chitosan coating enhanced the storage quality of the kutum salted roe as compared to an uncoated salted roe (control). Chitosan coating combined with natamycin afforded better protection than chitosan coating for chemical parameters (TVB-N, PV, TBA). Remaining salt was determined lower than 2% for all treatment. The conclusion was showed the combination of chitosan coating and natamycin at a 10 mg per Kg of roe were increased shelf life of the kutum roe.
