Corn bran polysaccharides were extracted using an ultrasonic-assisted method with a yield of 33.50% and then carboxymethylated. The occurrence of modification was confirmed using Fourier transform infrared spectral analysis. The surface of polysaccharide particles became loosened following the carboxymethylation. The effect of sodium hydroxide concentration, reaction temperature, and the reaction time on the degree of substitution was investigated, and the relationship among the substitution degree, total phenolic content and antioxidant activity were studied.
