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.
以甜叶菊副产物为原料，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）。甜叶菊副产物的主要成分是纤维素，葡萄糖转化为其他单糖，在 SDF 中形成一系列化合物。处理方法对单糖组成、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。鉴于最终产物的安全性、高得率和均一性以及良好的热稳定性，物理-酶法将是从甜叶菊副产物生产 SDF 的最佳选择。所得 SDF 可用作食品工业中的膳食补充剂和添加剂。
