In this study,high-pressure homogenization assisted with acidolysis treatment was employed to produce BSS cellulose nanofiber(CNF),and the structure was characterized by powder X-ray diffraction(XRD),Fourier-transform infrared(FT-IR) spectroscopy,atomic force microscopy(AFM),high resolution transmission electron microscopy(HTTEM),thermogravimetric analysis(TGA),and ^13 C nuclear magnetic resonance(NMR). Moreover,the structure and properties of CNF were compared with those of BSS insoluble dietary fiber(IDF). The results showed that CNF was in the form of a grid-like micro fiber,and its particle size was obviously reduced,while the crystallinity,thermal stability and solubility were increased. The results indicated that high-pressure homogenization assisted with acidolysis treatment was an effective method to prepare the BSS CNF,which could be a promising biopolymer reinforced material.展开更多
