The present invention is directed to a particular arabinoxylan (“AX”) preparation and the finding that this preparation has a beneficial effect on the organization of the intestinal microbial community in the lumen and in particular at the site of the gut mucosa, where it modulates the barrier function of the intestinal surface, primarily by modulating the mucosa-associated microbial community towards a relative increase of health beneficial bacteria, such as bifidobacteria and lactobacilli. It is accordingly a first aspect of the present invention to provide said arabinoxylan preparation characterized in comprising isolated water-soluble arabinoxylans and the use thereof to improve functioning (e.g. barrier function) of the intestinal epithelium. Thus, in a further aspect the present invention provides compositions, both pharmaceutical and nutritional compositions, comprising said arabinoxylan preparations; in particular pharmaceuticals, medical foods, food supplements or food compositions, such as infant formula products, dairy products, bakery products or pastry products. The compositions optionally comprise probiotics such as Bifidobacterium or Lactobacillus.

The preparation method of an anti-intestinal adhesion double-layer biogel provided by the present invention comprises the following steps: S1: preparing chitosan solution in advance; S2: preparing pure methacrylated chitosan; S3: preparing methyl Acrylated chitosan solution; S4: preparation of pure HA-DA-AEMA; S5: preparation of HA-DA-AEMA solution; S6: curing HA-DA-AEMA solution and methacrylated chitosan solution respectively An inner biogel that adheres to tissues and an outer biogel that resists adhesion. The inner layer of biogel that adheres to the tissue can be tightly combined with the surface of the intestine, which can fix the intestinal wound and prevent inflammatory exudation and bleeding. The anti-adhesion outer layer of biogel can avoid adhesion to the tissue. The viscous surface of the inner biogel adheres to the abdominal cavity or other intestinal tracts, avoiding the pain caused by intestinal adhesions to patients.
