Abstract: A method of purifying enzymatically isomerized glucose syrups containing fructose. These syrups contain salts which contribute to the ash content, colored bodies, odoriferous materials, and other impurities. To remove these impurities, the isomerized, glucose syrups are treated with a strong acid cation exchange resin in the hydrogen form which removes therefrom a portion of the colored bodies and appreciable quantities of the metallic constituents of the salts. Following this treatment, the syrups are subjected to a carbon treatment which removes the major portion of the colored bodies and odoriferous materials. The syrups are then treated with a weak base anion exchange resin in the free base form, a strong acid cation exchange resin in the hydrogen form, and with a strong base anion exchange resin in the hydroxyl form.

Abstract translation: 一种纯化含有果糖的酶异构化葡萄糖浆的方法。 这些糖浆含有有助于灰分含量的盐，着色体，气味物质和其它杂质。 为了除去这些杂质，异构化的葡萄糖浆用氢形式的强酸性阳离子交换树脂处理，从而从其中除去一部分着色体和明显量的盐的金属成分。 在这种处理之后，对糖浆进行碳处理，除去着色体和气味物质的主要部分。 然后用游离碱形式的弱碱阴离子交换树脂，氢形式的强酸阳离子交换树脂和羟基形式的强碱阴离子交换树脂处理糖浆。
