A study was made of the biological value of acid and enzymatic hydrolysates from capelin, luminous anchovy and krill. Hydrolysates were obtained with the use of protosubtilin G-10-X or hydrochloric acid. The products were found to contain 39 to 64% of "crude" protein, with about 40% of total nitrogen belonging to non-protein one, 0.47-2.07% of lipids, 29.7-54.3% of mineral substances including 26.6-52.4% of sodium chloride. All the hydrolysates were limited in tryptophan, the deficiency being more demonstrable in acid hydrolysates. Enzymatic hydrolysate from luminous anchovy was rich in sulfur-containing amino acids (score 112%), whereas the remaining products were marked by their deficiency (score 53-90%). The products were rich in lysine, leucine, isoleucine, and aromatic amino acids. The anabolic efficacy was discovered to be the highest for enzymatic hydrolysate from luminous anchovy, exceeding the analogous characteristics for casein. The biological value of hydrolysate from capelin and krill was lower than that of casein. This was supported by the amino acid analysis data. The assimilability of all hydrolysates was established as fairly high. Hydrolysates are employed for manufacturing broth bricks and pastes.
对毛鳞鱼、七星底灯鱼和磷虾的酸水解产物和酶水解产物的生物学价值进行了研究。水解产物是使用枯草杆菌蛋白酶G - 10 - X或盐酸获得的。结果发现，这些产品含有39%至64%的“粗”蛋白，其中约40%的总氮属于非蛋白氮，0.47 - 2.07%的脂质，29.7 - 54.3%的矿物质，其中包括26.6 - 52.4%的氯化钠。所有水解产物的色氨酸含量都有限，酸水解产物中的缺乏更为明显。七星底灯鱼的酶水解产物富含含硫氨基酸（得分112%），而其余产品则明显缺乏（得分53 - 90%）。这些产品富含赖氨酸、亮氨酸、异亮氨酸和芳香族氨基酸。结果发现，七星底灯鱼的酶水解产物的合成代谢功效最高，超过了酪蛋白的类似特性。毛鳞鱼和磷虾水解产物的生物学价值低于酪蛋白。氨基酸分析数据支持了这一点。所有水解产物的同化率都相当高。水解产物用于生产汤块和汤糊。
