    • The present invention provides a method for the extraction and isolation of solubilised arabinoxylan depolymerisation products, using arabinoxylan-containing plant material as a starting material. Preferably, such solubilised arabinoxylan depolymerisation product is any one of soluble arabinoxylan, arabinoxylan-oligosaccharides, xylose and arabinose. Said method comprises the mashing of said arabinoxylan-containing plant material in water and treating it with an appropriate concentration of an endoxylanase enzyme preparation in order to enzymatically depolymerise and solubilise a fraction of the arabinoxylans comprised in said plant material, wherein said endoxylanase treatment is followed or preceded by an acid treatment. This acid treatment comprising the incubation of said plant material in an acidified aqueous mash in order to obtain a depolymerisation and solubilisation of another fraction of the arabinoxylans comprised in said plant material. Preferably, said acidified mash is obtained by adding to said mash a strong acid to a final concentration between 0.02 and 0.4 N. The method further comprises the separation from said mashed plant material of a water-solubilised fraction, which comprises at least part of the solubilised arabinoxylan depolymerisation products.
    • 本发明提供了使用含阿拉伯木聚糖的植物材料作为起始原料提取和分离溶解的阿拉伯木聚糖解聚产物的方法。 优选地,这种溶解的阿拉伯木聚糖解聚产物是可溶性阿拉伯木聚糖,阿拉伯木聚糖寡糖,木糖和阿拉伯糖中的任一种。 所述方法包括将所述含阿拉伯木聚糖的植物材料在水中混合并用合适浓度的内切木聚糖酶制备物处理,以便酶促解聚和溶解包含在所述植物材料中的一部分阿拉伯木聚糖,其中遵循所述内切木聚糖酶处理 或之前进行酸处理。 该酸处理包括将所述植物材料温育在酸化的含水糊状物中,以获得包含在所述植物材料中的另一部分阿拉伯木聚糖的解聚和溶解。 优选地,所述酸化的醪液通过将强酸添加至0.02-0.4N的最终浓度而获得。该方法还包括从所述捣碎的植物材料中分离水溶性部分,其包含至少部分 溶解的阿拉伯木聚糖解聚产物。
