Modification of Ginseng Insoluble Dietary Fiber by Enzymatic Method: Structural, Rheological, Thermal and Functional Properties

Abstract

In this study, the effects of enzymatic modification using cellulase/xylanase on the composition and structural and functional properties of ginseng insoluble dietary fiber (G-IDF) were evaluated. Fourier transform infrared spectroscopy and scanning electron microcopy showed that enzymatic extraction treatment caused obvious structural alterations in ginseng-modified (G-MIDF) samples, which exhibited more porous and completely wrinkled surfaces. Comparing the peak morphology of G-MIDF with untreated IDF using X-ray diffractometry, the G-MIDF sample exhibited split peaks at a 2θ angle of 23.71°, along with the emergence of sharp peaks at 28.02°, 31.78°, and 35.07°. Thermo-gravimetric analysis showed that G-MIDF exhibited a specified range of pyrolysis temperature and is suitable for food applications involving processing at temperatures below 300 °C. Overall, it was evident from rheograms that both G-IDF and G-MIDF exhibited a resemblance with respect to viscosity changes as a function of the shear rate. Enzymatic treatment led to significant (p < 0.05) improvement in water holding, oil retention, water swelling, nitrite ion binding, bile acid binding, cholesterol absorption, and glucose absorption capacities.

Development of Highly Hygienic Textile by Coating with Encapsulated Ginseng Oil

“…Meanwhile, ginseng oil contains not only ginsenosides but also various components such as aromatic compounds, carbohydrates, and proteins. Therefore, in the ginseng oil spectrum, strong peaks appeared at 2923 cm −1 (C-H stretching), 2852 cm −1 (stretching vibration of the -CH 2 -groups), and 1742 cm −1 (stretching vibration of the C=O group in volatile oils and other carbonyl-containing compounds) [39]. Notably, oils are characterized by strong characteristic peaks in FT-IR spectra.…”

Impact of water combined wet ball milling extraction and functional evaluation of dietary fiber from papaya (Carica papaya L)

“…Epidemiological research conducted on humans and animals has demonstrated that DFs, which are non-starch polysaccharides, exhibit several significant biological properties ( Jiang et al, 2023 ; Jiang, Wu, Ameer, Li, & Ramachandraiah, 2020 ). Among the various health benefits, soluble dietary fiber (SDF) is known to enhance viscosity, lower blood sugar levels, and increase plasma cholesterol.…”
