Low-GI pure plant-based peptide composition as well as preparation method and application thereof

The invention relates to a low-GI pure plant-based peptide composition as well as a preparation method and application thereof. The low-GI pure plant-based peptide composition comprises the following components in parts by mass: 1-10 parts of cereal powder, 0.5-5 parts of tea protein, 0.5-5 parts of coconut protein isolate, 1-5 parts of micrococcus powder, 1-10 parts of DHA algal oil powder, 0.5-5 parts of rice oligopeptide, 1-5 parts of an oriental cherry flower extract and 0.1-5 parts of a stevia rebaudiana extract. Compared with the prior art, the low-GI pure plant-based peptide composition is prepared by strictly screening food raw materials, medicinal and edible traditional Chinese medicines and functional components without toxic and side effects and adopting a one-step granulation and multi-layer coating technology, so that the effects of improving the gastrointestinal function, not damaging the stomach and intestine, realizing positioned release and mild conditioning are achieved; therefore, the funct
