The invention relates to the technical field of preparation of health-care drinks, and particularly discloses brain
peptide oral liquid capable of tonifying the
kidney, strengthening the
spleen and promoting intelligence and a preparation method of the brain
peptide oral liquid. The brain
peptide oral liquid is prepared from the following raw materials: longan
aril, fructus lycii, mulberries, red dates, poria cocos, fructus alpiniae oxyphyllae, rhizoma zingiberis, peptide components, DHA algal oil, N-acetylneuraminic acid, gamma-
aminobutyric acid,
vitamin B12,
stevioside, concentrated apple juice and
purified water. The preparation method of the brain peptide oral liquid comprises the following steps: mixing longan
aril, Chinese wolfberry fruits, mulberries, red dates, poria cocos, fructus alpiniae oxyphyllae, dried ginger and
purified water, performing decoction, and combining decoctions to obtain a
traditional Chinese medicine extracting solution; adding peptide components and DHA algal oil into the
traditional Chinese medicine extracting solution, uniformly stirring, adding N-acetylneuraminic acid, gamma-
aminobutyric acid,
vitamin B12,
stevioside and concentrated apple juice, adjusting the pH value, and sterilizing to obtain the brain peptide oral liquid. The prepared brain peptide oral liquid for tonifying the
kidney, strengthening the
spleen and developing intelligence has remarkable effects of tonifying the
kidney and strengthening the
spleen.
