| 中文摘要: |
| 利用分析化学方法对水解鱼蛋白、经超滤的水解鱼蛋白、鱼粉、酪蛋白、豆粕的营养成分进行了分析、评价。结果表明，经超滤的水解鱼蛋白的蛋白质含量显著高于未经超滤的水解鱼蛋白的蛋白质含量（P<0.05），超滤减少了水解鱼蛋白的脂肪含量，增加了水解鱼蛋白的灰分含量；水解鱼蛋白、经超滤的水解鱼蛋白、鱼粉、酪蛋白、豆粕氨基酸总量依次为62.24、62.34、50.78、74.33、37.36 mg/100 mg，必需氨基酸占总氨基酸的比值（EAA/TAA）依次为47.41%、49.47%、49.90%、48.41%、49.25%；水解鱼蛋白含有丰富的牛磺酸；水解鱼蛋白和鱼粉含有丰富的碘和硒；水解鱼蛋白和鱼粉中维生素B2和B5含量较为丰富。水解鱼蛋白具有平衡的氨基酸组成，较高水平的牛磺酸和维生素B2、B5、丰富的微量元素碘和硒，是优质的蛋白原料。 |
| 英文摘要: |
| Nutritional compositions of fish protein hydrolysate (FPH), ultramembrane filtered fish protein hydrolysate (UF） FPH, fishmeal, casein, and soybean meal were analyzed and compared in this study. The results showed that the content of protein in ultramembrane filtered fish protein hydrolysate was significantly higher than that in fish protein hydrolysate without ultrafiltration. The lipid content in fish protein hydrolysate was reduced by ultrafiltration and the ash content was increased. The total amino acid in fish protein hydrolysate, ultramembrane filtered fish protein hydrolysate, fishmeal, casein, and soybean meal were 62.24, 62.34, 50.78, 74.33, 37.36 mg/100mg, respectively, and the percentage of essential amino acids to the total amino acids (EAA/TAA) were 47.41%, 49.47%, 49.90%, 48.41%, 49.25%, respectively. Taurine is rich in fish protein hydrolysate. Fish protein hydrolysate and fishmeal also have abundant iodine, selenium and vitamin B2, B5. In conclusion, fish protein hydrolysate is a high quality protein material with balanced amino acids, relatively high contents of vitamin B2 and B5, and abundant microelements of iodine and selenium. |
