Abstract:

It is the research on main nutrient components and chemical protein evaluation of Acipenser schrenckii roe that provide reference for deep processing of Acipenser schrenckii roe and scientific basis for exploitation, and comprehensive utilization of Acipenser schrenckii resources. The nutritive components of Acipenser schrenckii roe were determinated by conventional analytical methods. The results showed that the crude protein content of Acipenser schrenckii roe was 26.00%. The 18 amino acids content of Acipenser schrenckii roe was 25.21%. Among these amino acids, the essential amino acids content was 10.16%, and the fraction of essential amino acids was approximately 40.30%. The ratio of essential amino acids to non-essential amino acids was 67.51%. Tryptophane, the first limiting amino acids, scores 92. The unsaturated fatty acids amount of ASO was 62.8%. The EPA and DHA amount of Acipenser schrenckii roe reached to 10.3%. The content of mineral elements, such as Fe and Zn, were high. Its content was 22.07 mg/kg, 18.00 mg/kg, respectively. Acipenser schrenckii roe had the characteristics of high protein, low carbohydrate, and reasonable proportion of amino acid, abundant minerals and abundant unsaturated fatty acid, which had a bright application future.
