Jia, Mengyun published the artcileStructural characteristics and functional properties of soluble dietary fiber from defatted rice bran obtained through Trichoderma viride fermentation, Application of (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Trichoderma fermentation soluble dietary fiber defatted rice bran.
Trichoderma viride was utilized to ferment the defatted rice bran (DRB), and soluble dietary fiber was prepared before and after fermentation, named as B-SDF and F-SDF, resp. Optimum fermentation conditions for yield of F-SDF were determined using response surface methodol. (RSM). The yield of F-SDF was significantly increased from 10.5 (weight/weight, %) to 33.4 (weight/weight, %) under the optimal conditions (inoculum size = 10%, pH = 5.8 and time = 41 h). Fourier transform IR spectroscopy (FTIR) demonstrated that both B-SDF and F-SDF had typical characteristics of the IR spectrum of polysaccharides, and X-ray diffraction (XRD) revealed they were mainly substances of amorphous structure. In addition, F-SDF showed looser structure by SEM (SEM) anal., increased mol. weight by high-performance gel permeation chromatog. (HPGPC) anal., and more complex monosaccharide composition by high-performance anion exchange chromatog. (HPAEC) anal. Furthermore, functional properties anal. showed that F-SDF exhibited higher water-holding capacity (WHC), oil-holding capacity (OHC), water solubility (WS) and cholesterol absorption capacity (CAC) than B-SDF. In summary, the present study suggested that SDF from defatted rice bran obtained through Trichoderma viride fermentation has a higher potential to be used as a functional ingredient in foods.
