一种富含半乳甘露聚糖的可溶性膳食纤维及其制备方法
摘要：
本发明公开了一种富含半乳甘露聚糖的可溶性膳食纤维及其制备方法，所述半乳甘露寡糖的质量百分比为20％～30％。本发明提供的β‑甘露聚糖酶稳定性好，比酶活力高，在食品、饲料等行业中具有很大的应用价值；本发明提供的制备方法的水解率及半乳甘露聚糖转化率高、产物易于分离、最终产品的重均分子量约为24800Da；利用本发明提供的制备方法可以生产含半乳甘露寡糖的可溶性膳食纤维糖浆和糖粉两种产品，且产品收率高，其收率分别为74.2％和72.8％。
摘要（英）：

The invention discloses soluble dietary fibers rich in galactomannan and a preparation method of the soluble dietary fibers. The mass percentage of galactomannan is 20-30%. Beta-mannase provided by the invention is better in stability and higher in activity than enzyme, and has great application value in the trade of foods, feeds and the like. According to the preparation method provided by the invention, the hydrolysis rate and the galactomannan conversion rate are high, products are easy to separate, and the weight-average molecular weight of finished products is about 24800Da; and two kinds of products of soluble dietary fiber syrup and powdered sugar, containing the galactomannan, can be produced by the preparation method provided by the invention, besides, the yield of products is high, the yield of the soluble dietary fiber syrup is 74.2%, and the yield of the powdered sugar is 72.8%.
