    摘要： A lactose-containing solution such as a lactose aqueous solution, wherein milk or the like is placed in contact with a β-galactosidase-containing solution, with a dialysis membrane intervening therebetween to decompose lactose in the solution. Thus, a β-galactosidase-free solution of the lactose decomposition product is obtained. This enzymatic reaction is conducted at temperatures not higher than the optimal temperature of used enzyme, preferably 0-10°C, with the amount of enzyme being 30 to 250 units, preferably 62.5-250 units per 1 g of lactose in the lactose-containing solution. The area of the dialysis membrane intervening between the enzyme-containing solution and the substrate-containing solution is preferably selected so that it actually becomes largest with respect to the volume of the enzyme-containing solution used.

    摘要翻译： 将含乳糖的溶液如乳糖水溶液与其中含有β-半乳糖苷酶的溶液接触的乳糖等与介入其间的透析膜分解溶液中的乳糖。 因此，获得了不含β-半乳糖苷酶的乳糖分解产物溶液。 该酶反应在不高于所用酶的最佳温度的温度下进行，优选为0-10℃，酶含量为含有乳糖的1g乳糖中30至250单位，优选62.5-250单位 解。 优选选择介于含酶溶液和含底物溶液之间的透析膜的面积，使其相对于所用含酶溶液的体积实际上变得最大。

    摘要： A lactose-containing solution such as a lactose aqueous solution, wherein milk or the like is placed in contact with a (Beta)-galactosidase-containing solution, with a dialysis membrane intervening therebetween to decompose lactose in the solution. Thus, a (Beta)-galactosidase-free solution of the lactose decomposition product is obtained. This enzymatic reaction is conducted at temperatures not higher than the optimal temperature of used enzyme, preferably 0 - 10 C, with the amount of enzyme being 30 - 250 units, preferably 62.5 - 250 units per 1 g of lactose in the lactose-containing solution. The area of the dialysis membrane intervening between the enzyme-containing solution and the substrate-containing solution is preferably selected so that it actually becomes largest with respect to the volume of the enzyme-containing solution used.
