【摘要】 本实验用微波法对野皂荚胶进行阶段性降解。通过微波与强氧化剂、KOH的耦合以及微波法与酶法的耦合对黏度较高的野皂荚胶进行高浓度降解,经过微波处理用于酶解的浓度已达10%。微波处理后水解24h,半乳甘露低聚糖的纯度提高到73.8%,单糖含量为26.23%。更多还原

【Abstract】 The stagewise degradation process of G. heterophylla polysaccharide gum assisted by microwave was studied. Through the coupling of microwave treatment with strong oxidizer and KOH, as well as β-mannanase hydrolysis, the high viscosity of the gum was degraded to a lower level, with the concentration increasing from 1% to 10 %. After β-mannanase hydrolyzing the gum for 24 h, the content of galacto-mannan-oligosaccharides is up to 73.8%, while the content of monosaccharide is 26.23%.更多还原
