摘要: 本实验探讨了工业化生产高浓度IgG含量初乳粉的工艺条件。通过单因素实验研究了中空纤维超滤膜的超滤条件,确定最佳操作条件为:温度25℃、压力0.10MPa。为了能大规模生产更高浓度IgG含量的初乳粉,对超滤浓缩乳清进一步盐析,比较了两种方法,得出辛酸-硫酸铵法所得的冷冻干燥乳粉其IgG含量最高,达到85%左右,但饱和硫酸铵法更适宜大规模生产。

Abstract: The separating conditions of bovine colostrums whey by hollow fiber ultra-filtration were confirmed on the basis of single factor tests as the result of ultra-filtrating temperature 25 ℃ and pressure 0.10 MPa. The purity of IgG extracted by caprylic acid-ammonium sulphate method is higher than that of IgG extracted by saturated ammonium sulphate solution method, reaching 85%. But saturated ammonium sulphate solution method is more feasible for industrial mass production.
