【摘要】 通过营养成分的测定和大鼠生长和代谢试验,对上海鱼品厂生产的马面魨鱼蛋白粉进行了营养评价。 测得五份马面鲀鱼蛋白粉的平均营养素含量分别为:蛋白质82.1％,脂肪0.04％,灰分11.38％,钙3.44％,磷2.18％,铁24.6mg％。这个鱼蛋白粉不但蛋白质含量高,而且氨基酸的模式平衡好。每百克粗蛋白中赖氨酸总量达9.4g,其中可利用赖氨酸为8.23g。合硫氨基酸4.5g,色氨酸为1.3g。每百克鱼蛋白粉中舍维生素B₂ 1.27mg,尼克酸1.81mg。以此鱼蛋白粉喂养大鼠,测得蛋白质功效比值为2.97（校正值为2.53）,净蛋白质比率（NPR）为4.29,真消化率（TD）为92.9％,生理价值（BV）为73.7％,净蛋白质利用率（NPU）为68.5％,与酪蛋白对照组相比,除真消化率较低外,其余各项指标均无显著差异。是一个很好的蛋白质补充品。更多还原

【Abstract】 The nutritive quality of Monacanthus Modestus fish Protein Concentrate (FPC) produced by Shanghai Fish Products Factory was evaluated by means of food analysis and animal experiment techniques. The average nutrients contents from 5 samples of Monacanthus Modestus FPC are: protein 82.1%, fat 0.04%, ash 11.38%, calcium 3.44%, phosphorus 2.18%, iron 24.6%. The FPC contains not only high protein content but also a well balanced essential amino acid pattern. The amount of amino acids contained in 16g nitrogen are: total lysine 9.4g, in which the available lysine is 8.23g; sulphur containing amino acids 4.5 g; tryptophan 1.3g. The vitamin B2 in 100 g of FPC is 1.27 mg, that of niacin is 1.81 mg. The protein efficiency ratio (PER) of this FPC is 2.97 (corrected PER is 2.53). The net protein ratio (NPR) is 4.29. The true digestibility (TD) is 92.9%. The biological value (BV) is 73.7%. The net protein utilization is 68.5%. There is no significant difference in these criteria between FPC and casein control group, except its lower digestibility of the FPC. It can be concluded that the FPC tested is a good protein supplement.更多还原
