    摘要： A process for the preparation of long-chain inulin having an average chain length greater than 20 monomer units while simultaneously obtaining glucose and fructose is performed. An aqueous crude inulin suspension with a crude inulin concentration of 20-70% by weight is subjected to enzymatic treatment with inulinase at temperatures of 30.degree.-70.degree. C. During the process the short-chain components are degraded to mono- and disaccharides, and the long-chain inulins are then separated off from the mono- and disaccharides and converted into dry form. The long chain inulins may be separated from the mono- and disaccharides by crystallization by cooling and centrifugation or chromatographically using a strongly acidic cation exchange resin loaded with calcium ions. The long chain inulins can be used as a component in foodstuffs, in conjunction with sweeteners, bulking agents, thickeners, stabilizers, as well as a fat substitute in foodstuffs, a carbohydrate substitute, dietary fiber, as an excipient for pharmacologically active substances, and as an indicator for kidney clearance.

    摘要翻译： 进行平均链长大于20个单体单元同时获得葡萄糖和果糖的长链菊糖的制备方法。 将粗制菊粉浓度为20-70％（重量）的粗制菊糖悬浮液用菊粉酶在30-70℃的温度下进行酶处理。在该过程中，短链组分降解为单糖和二糖， 然后从单糖和二糖中分离长链乳清素并转化为干燥形式。 通过冷却和离心或使用负载有钙离子的强酸性阳离子交换树脂进行色谱分离，可以将长链乳清素与单糖和二糖分离。 长链乳清素可以与食品中的成分，甜味剂，膨化剂，增稠剂，稳定剂以及食品中的脂肪替代物，碳水化合物替代品，膳食纤维，药理活性物质的赋形剂一起用作食品中的组分，以及 作为肾脏清除的指标。
