以芭蕉芋下脚料为原料，采用化学法、物理化学法、酶法、物理酶法、化学酶法和物理化学酶法6种方法制备可溶性膳食纤维（SDF）。作为C.香菇的副产物由纤维素组成，葡萄糖转化为其他单糖，形成SDF中的一系列化合物。处理方法对最终产品的单糖组成、金属离子含量、分子大小分布、结构中的化学键和基团、热性能和颜色都有影响。从安全性、产率高、均一性好、热稳定性好等方面考虑，物理-酶法是从香菇中提取SDF的最佳方法。香菇副产物。所获得的SDF可用作食品工业中的膳食补充剂和添加剂。
Using Canna edulis Ker by-product as raw materials, soluble dietary fiber (SDF) was prepared using six different methods, including chemical, physical–chemical, enzymatic, physical–enzymatic, chemical–enzymatic and physical–chemical–enzymatic methods. As main component in the C. edulis by-product composed of cellulose, glucose converts to other single sugars, which form a series of compounds in the SDF. The treated methods have impact effects on single sugar composition, metal ion content, molecular size distribution, chemical bonds and groups in the structure, thermal property and color of the final product. In view of security, high yield and homogeneity as well as good thermal stability of final product, physical–enzymatic method will be a best choice for the production of SDF from C. edulis by-product. The SDF obtained can be used as dietary supplement and additive in the food industry.
