For this study, common Kilka was coated with 20% whey protein concentration. Non- coated Kilka also was used as a control. Coated and non-coated samples were then stored at -18 °C for six months. Bacterial, chemical and sensory properties of the samples were determined in each month. Results showed that Coliform, Escherichia coli and P seudomonas bacteria contaminations were negative until the end of storage period in the covered samples. Total bacterial counts and Staphylococcus bacteria count were lower in the test samples compared with the control samples. Humidity, protein, lipid, ash and calorie contents were higher in test samples as compared with the control samples, while peroxide value, free fatty acids, thiobarbitoric acid, TVN and pH were lower in test samples. Taste, odor, color, tissue and overall acceptability were studied in the test and control samples. These specifications had a better quality in test samples compared with the control ones. These factors showed a significant difference in the uncoated samples (control) (p CP - IRAN IN - LG - eng PB - IFRO PG - 132 PT - Orginal research papers YR - 2012
