Embodiment 1

[0063] 1. Extraction of Water-Insoluble Arabinoxylan

[0064] (1) Wheat bran pretreatment

[0065] Take the pulverized wheat bran and add deionized water according to the ratio of material to liquid 1:10 (g / mL), put it in an enzymolysis tank and raise the temperature to 93°C, add 0.6mL of high-temperature amylase stock solution per 100g of wheat bran, and stir for enzymolysis 3h, cool down to the optimal temperature of alkaline protease at 63°C, add 0.8mL of alkaline protease stock solution for every 100g of wheat bran, stir for 3h, heat up to 100°C after the enzymolysis process, keep warm for 10min to kill enzyme, enzymolysis solution with Centrifuge at a speed of 4000r / min for 10min, wash the obtained precipitate three times with deionized water, and freeze-dry to obtain destarch and deproteinized wheat bran.

[0066] (2) Alkaline extraction of water-insoluble arabinoxylan

[0067] Take the prepared destarched and deproteinized wheat bran, mix it with a NaOH solution with ...

Abstract

The invention discloses an araboxylan hydrogel with pH responsiveness and a preparation method thereof, and belongs to the technical field of functional natural macromolecular hydrogel. According to the preparation method, wheat bran AX is prepared by an alkali extraction method, and carboxylation modification is carried out on the wheat bran AX to obtain wheat bran CMAX. CMAX is an anionic polysaccharide; in combination with the structural characteristics (high relative molecular mass, high viscosity and the like) of CMAX, ion gel is prepared by an Fe3+ ion gel method; and the ion gel has high affinity and can be cross-linked with polysaccharide to form functional gel with pH responsiveness, thereby providing possibility for the delivery of functional components in a human body. The technology is simple and convenient to operate, low in cost and good in safety.

Description

technical field [0001] The invention relates to a pH-responsive arabinoxylan hydrogel and a preparation method thereof, belonging to the technical field of functional natural macromolecular hydrogels. Background technique [0002] Wheat bran is a by-product of wheat that makes up approximately 14-19% of the weight of the wheat kernel and is often discarded or sold as animal feed due to its harsh taste. However, wheat bran is rich in nutrients such as dietary fiber (46%), protein (15-22%), minerals and vitamins, and has high nutritional value. Among them, about 70% of the dietary fiber is arabinoxylan (AX), 24% is cellulose, and 6% is β-glucan, and the annual output of wheat bran in my country can reach more than 30 million tons. If it is discarded, it will cause Huge waste of resources. [0003] Arabinoxylan (AX) is a hemicellulose present in the cell walls of cereals, including wheat. They are backbones composed of β-(1-4)-linked D-xylosyl residues, to which α-L-arabinoxy...
