Abstract :

Abstract             The efficiency of BHT antioxidant was studied on the fat stability of Great sturgeon (Huso huso)diet comparison under three month's cold condition period. In this research, after preparing primary material and making compound diet pellet it used BHT antioxidant in the scale of 0.05% diet lipid. Some groups of diets were taken as witness chemical Indicators of lipid spoilage (Total lipid, free fatty acid, peroxide value) were investigated during monthly storage period for diets which contain antioxidant and witness. Results showed that total lipid of antioxidant diet in comparison with witness diet only occurs with statistically significant difference in the third month of storage. Quality factors of lipid spoilage (Peroxide value, free fatty acid) showed significant difference between witness diet and antioxidant diet except in the first month of storage. The results of this study indicated that although the lack of antioxidant decreases fat quality diet, the use of mentioned compound decreased the quality drop age of diet indicators during the storage period.
