| 摘 要： | 采用6～10 kD和3 kD超滤膜对猪血红蛋白水解液进行浓缩实验,对超滤前后的多肽类蛋白质、氨基氮、血红素的变化进行分析.实验结果表明:采用3 kD超滤膜对酶解液的浓缩效果较好,浓缩倍数分别达到2.3、2.0、1.9,经冷冻干燥得产物蛋白质多肽含量91%,血红素含量2.9%混合营养物,可以用来制备含量较高的富含血红素肽的混合营养物. |

| Abstract: | The enzymatic hydrolysate of porcine hemoglobin was concentrated with 6～10 kD and 3 kD ultrafiltration membrane in this experiment. The changes of contents of protein, amino nitrogen and hemochrome were investigated. The results showed that 3 kD ultrafiltration membrane was fit for concentrating enzymatic hydrolysate. The multiples of concentration of peptides, amino nitrogen and hemochrome were 2.3, 2.0 and 1.9 respectively. Through refigeration and drying,a substance containing 91% of protein peptides and 2.9% of hemochrome. So it can be used in preparing mixed nutrition substance with abundant hemochrome peptides. |
| Keywords: | ultrafiltration membrane peptides enzymatic hydrolysate |
