“…Carboxymethylation modification has been shown to increase the water solubility and bioactivity of native polysaccharides ( Xie et al, 2021 , Zhao et al, 2022 , Duan et al, 2020 ). Wei et al found that the carboxymethylation of corn fiber gums enhanced the physical stability of pea protein dispersions ( Wei, Lou, Cai, Li, & Zhang, 2022 ). Wang et al further showed that carboxymethylation could increase the water solubility and antioxidant activity of the polysaccharide from Tremella fuciformis ( Wang, Zhang, & Zhao, 2015 ).…”
