Abstract
Preparation of soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) using Pinus Koraiensis nut coated-film as raw material, and xylanase in insoluble dietary fiber modification, prepared modified soluble fiber (MSDF) and modified insoluble dietary fiber (MIDF), and determined the dialysis delay index of glucose, cholesterol, sodium cholate adsorption capacity and glucose. Results: the glucose adsorption capacity of MSDF was significantly higher than that of SDF, and the glucose adsorption capacity of MIDF was significantly higher than that of IDF. In the simulated gastric environment, the cholesterol adsorption capacity of modified dietary fiber was improved, and MSDF was significantly higher than SDF. The adsorption capacity of MIDF sodium cholate was significantly higher than IDF, up to 60.73 mg/g, which was 2.98 times that of IDF. The glucose dialysis delay index of MIDF was higher than IDF, and it became stable at 120 min, reaching 21.69%, and increased significantly of 7.24% than IDF. Therefore, xylanase can improve the functional properties of pine fiber film dietary fiber, and the xylanase modification is an excellent modification method on dietary fiber of nut coated-film.
