persian sturgeon (acipenser persicus) is one of the most important fish in caspian sea and demand for its fillets is considerable, study to improve the packaging and protect their quality during storage is necessary. in this study persian sturgeon fillets were packed under 30% vacuum then freezed and effect of this packaging method on decreasing and delaying lipid rancidity was studied by measu...

The scarcity of conventional feed resources and their high price has necessitated exploring cost effective non-conventional ingredients to be utilized to replace the conventional ones like hatchery waste (HW). The chemical composition of HW has revealed its nutrient composition especially higher level of fat (1821%), which pose threat to spoil the quality of of product through rancidity. Hatche...

The effect of aqueous solutions of ascorbic acid (AA) on the rancidity development in Cobia (Rachycentron canadum) fillets during frozen storage was studied. Cobia fillets were treated with ascorbic acid (AA 0.25% and AA 0.5%) then stored at -18°C up to 6 months. Rancidity development was measured by several biochemical indices including free fatty acids (FFA), peroxide value (PV), an...

The aim of the study was to develop a Quality Index Method (QIM) scheme for maatjes herring stored in air and under a modified atmosphere at 4°C and 10°C. The attributes included in this new scheme are: appearance of skin side and bone side, color of the blood, odor (rancidity and other), taste (rancidity and other), aftertaste and texture. The QIM scheme developed proved to be potentially usef...
