摘要: A method for easily and efficiently separating a sialyllactose material from a milk material by exploiting the pH-dependent interactions between whey proteins and sialyllactose is disclosed. The method comprises concentrating a milk material at a pH of 5.2 or lower to obtain a concentrate, adjusting the pH of the concentrate to 5.5 or higher, and obtaining a low-molecular-weight fraction from the pH-adjusted concentrate. Since the method also allows separation of sialyllactose from lactose and minerals, sialyllactose may be obtained at high purity. The resulting sialyllactose material is highly useful for food, pharmaceutical, and other applications.

摘要: A method for easily and efficiently separating a sialyllactose material from a milk material is disclosed. The method comprises removing proteins from the milk material to obtain a protein-free liquid, adjusting the pH of the protein-free liquid to obtain a pH-adjusted liquid, and concentrating the pH-adjusted liquid by an ultrafiltration (UF) membrane. Since the method also allows separation of sialyllactose from lactose and minerals, sialyllactose can be obtained with high purity, making the sialyllactose material highly useful for food, pharmaceutical, and other applications.
摘要翻译: 公开了一种从牛奶材料中容易且有效地分离唾液乳糖材料的方法。 该方法包括从乳制品中除去蛋白质以获得无蛋白质的液体,调节无蛋白质液体的pH以获得pH调节的液体,并通过超滤(UF)膜浓缩pH调节的液体。 由于该方法还允许唾液乳糖与乳糖和矿物质分离,所以可以获得高纯度的唾液乳糖,使得唾液酸乳糖材料对于食品,药物和其它应用非常有用。
