Abstract: The gelation capacity, rheological properties, structural characteristics, swelling capacity and color of hydrogels obtained from three wheat bran arabinoxylans (WBAX, W9023, W58, W27s) from different wheat cultivars (Zhengmai 9023, Aizhang 58 and Zhoumai 27) were studied. W9023 and W58 gels (Q9023, Q58) were prepared by oxidative crosslinking with laccase at a substrate concentration of 3 g/100 mL. The gelation time of Q9023 and Q58 were 9 and 19 min, respectively. WBAXs presented typical Fourier transform infrared (FT-IR) spectra of arabinoxylans. Scanning electron microscopy (SEM) analysis showed that Q9023 presented a smooth surface topography, while Q58 presented a ridge structure. According to these results, Q9023 showed the most stable structure and good controlled release capability as well as a light color. The study can provide a reference for the modification of arabinoxylan hydrogel in the future.
