Herba potentillae discoloris and soybean protein peptide beverage capable of lowering blood sugar and preparation method of beverage

The invention belongs to the technical field of foods, relates to a food with a blood sugar lowering function, and particularly relates to a herba potentillae discoloris and soybean protein peptide beverage capable of lowering blood sugar and a preparation method of the beverage. Aiming at overcoming the disadvantages of the prior art, herba potentillae discoloris with the blood sugar lowering function is combined with soybean protein peptide to prepare a functional peptide beverage capable of adjusting the blood sugar of a human body. The product is prepared from the following components in parts by weight: 5-10 parts of a herba potentillae discoloris decoction solution, 8-12 parts of a cortex lycii decoction solution, 6-8 parts of a folium mori decoction solution, 10-20 parts of soybean protein peptide liquid, 1-3 parts of xylitol and the balance of water. According to the herba potentillae discoloris and soybean protein peptide beverage, a technological process is simple, safe and reliable; the prepared product has a better taste; the adopted raw materials are natural and no chemical additive is added; and the problems of an existing blood sugar lowering preparation and an existing method that the preparation method is complicated, the effect of the blood sugar lowering product is not good, the toxic or side effect is greater and the product can not be eaten for a long time are solved.
