Steam explosion (SE) and cellulase treatment are potentially effective processing methods for by-products, for use in high-value applications. The treatment conditions were optimized by response surface methodology, increasing the soluble dietary fiber (SDF) yield by 1.52 and 1.16 times after the SE and cellulase treatments, respectively. The both treatments did not affect the functional groups and crystal types of the polysachharides, but both reduced the crystallinity. The SDF had a porous microstructure, which would increase the specific surface area and facilitates the adsorption of water and glucose, thereby improving its functional properties. SE and cellulase treatment significantly improved the hydration capacity of SDF; the glucose adsorption capacity increased by 1.15 and 1.07 times, respectively. Overall, the modified SDF showed different degrees of advantages in terms of yield, physicochemical and functionality. This study demonstrated that SE and cellulase are effective modification methods for SDF made from by-products.
蒸汽爆破（SE）和纤维素酶处理是用于高价值应用的副产品的潜在有效加工方法。通过响应面法对处理条件进行了优化，蒸汽爆破和纤维素酶处理后，可溶性膳食纤维（SDF）产量分别提高了1.52倍和1.16倍。两种处理均未影响多糖的官能团和晶体类型，但均降低了结晶度。SDF具有多孔微观结构，这会增加比表面积并促进水和葡萄糖的吸附，从而改善其功能特性。蒸汽爆破和纤维素酶处理显著提高了SDF的水合能力；葡萄糖吸附能力分别提高了1.15倍和1.07倍。总体而言，改性SDF在产量、理化性质和功能方面表现出不同程度的优势。本研究表明，蒸汽爆破和纤维素酶是用于由副产品制成的SDF的有效改性方法。
