The invention relates to the technical field of functional foods, and particularly discloses a
dietary therapy composition for promoting
functional recovery after
spinal cord injury and relieving
neuroinflammation as well as a preparation method and application of the
dietary therapy composition. The preparation method of the
dietary therapy composition comprises the following steps: dissolving corn
protein in an
ethanol solution, adding a
sodium deoxycholate solution, stirring and mixing to obtain a
mixed solution, adding indole-3-propionic acid, stirring until
ethanol is evaporated, putting into a
dialysis bag, adding a PBS
buffer solution, stirring to remove free indole-3-propionic acid, and freeze-
drying to obtain corn
protein-IPA nanoparticles; the preparation method comprises the following steps: adding
ultrapure water into
pectin, mixing and stirring, adding the corn
protein-IPA nanoparticles, continuously stirring uniformly, and freeze-
drying to obtain
pectin-corn protein-IPA nanoparticles, namely the required dietary therapy composition. The dietary therapy composition prepared by the invention can promote the
recovery of motor functions after
spinal cord injury, inhibit the activation of
oxidative stress, relieve
neuroinflammation and promote
axon regeneration.
