Starch nanocrystals (SNCs) have a small particle size and large surface area compared with traditional modified starch. In this study, SNCs were chemically modified by succinic anhydride in aqueous alkaline condition. With the ratio of succinic anhydride/SNCs (0.1–0.5) increasing, the degree of substitution of succinylated SNCs increases from 0.0481 to 0.1009, and the zeta potential becomes more negative. The SNCs and succinylated SNCs were characterized by Fourier transform infrared (FTIR), Scanning Electron Microscopy (SEM) and X-ray diffrac...
