The invention discloses a pH-responsive arabinoxylan hydrogel and a preparation method thereof, belonging to the technical field of functional natural macromolecular hydrogel. In the method of the present invention, wheat bran AX is prepared by an alkaline extraction method, and is subjected to carboxylation modification to obtain wheat bran CMAX. CMAX is an anionic polysaccharide, combined with its own structural characteristics (high relative molecular mass, high viscosity, etc.), the Fe 3+ ion gel method used in the present invention prepares ion gel, which not only has high affinity, but also can be combined with The cross-linking of polysaccharides to form pH-responsive functional gels provides the possibility for the delivery of functional ingredients in the human body. The technology is easy to operate, low in cost and good in safety. |
