The invention relates to a
traditional Chinese medicine composite
peptide composition having the function of improving
gastrointestinal tract functions and a preparation method of the
traditional Chinese medicine composite
peptide composition. The
traditional Chinese medicine composite
peptide composition comprises the following components in parts by weight: 5-13 parts of a
lophatherum herb extract, 4-10 parts of a
radix rehmanniae preparata extract, 4-10 parts of an Asiatic cornelian cherry fruit extract, 6-14 parts of radix angelicae sinensis microcapsules, 6-14 parts of
coix seed microcapsules, 8-16 parts of
casein peptide, 10-20 parts of wheat
oligopeptide, 8-12 parts of
xylooligosaccharide, and 1-13 parts of
inulin. The components of the traditional Chinese
medicine composite peptide composition are in compatibility, so that the effects of mutual promotion and synergistic interaction can be achieved, and the traditional Chinese
medicine composite peptide composition has good effect of improving
gastrointestinal tract functions. Radix angelicae sinensis and
coix seeds are subjected to supercritical CO2 extraction, then the radix angelicae sinensis and the
coix seeds after the supercritical CO2 extraction are entrapped to be made into microcapsules, and traditional Chinese medicines of
lophatherum herbs,
radix rehmanniae preparata, Asiatic cornelian cherry fruits and the like are subjected to pretreatment, extraction concentration and
spray drying so as to be made into extracts, so that main functional components of the medicines are reserved to the maximum extent, the eating amount is notably reduced, besides, the
biological availability of the medicines is greatly improved, the
medicine effect is notably improved, and the purpose of improving the
gastrointestinal tract functions is realized really.
