The invention relates to a preparation method of an almond peptide oral liquid for inhibiting activity of alpha-glucosidase, the almond peptide oral liquid is prepared from almond peptide nanoparticles, erythritol, glycerol, pectin, citric acid, sodium carboxymethyl cellulose, sodium cyclamate and purified water, and the almond peptide nanoparticles are prepared by embedding almond peptide proline-arginine (PR) and then freeze-drying. The almond peptide PR with alpha glucosidase activity inhibition is embedded, the embedding rate of the almond peptide PR is improved and reaches 88.09%, the particle size of the prepared almond peptide nano-particles is as small as 105.3 nm, the almond peptide nano-particles are stable in character in oral liquid, the alpha glucosidase activity inhibition performance of the almond peptide nano-particles is effectively kept and is not reduced, the stability of an embedded shell is excellent, and the almond peptide nano-particles can be applied to oral liquid preparation. And the
