Abstract

The invention relates to a method for preparing a bitter gourd solid beverage, in particular to the technical field of food preparations. The method comprises the following steps that pulp and seeds of bitter gourds are separated; the separated pulp of the bitter gourds is prepared into bitter gourd instant powder; the separated seeds of the bitter gourds are prepared into bitter gourd small molecule polypeptide; auxiliary materials are added to the bitter gourd instant powder and the bitter gourd small molecule polypeptide to prepare the bitter gourd solid beverage. According to the method, with the fresh bitter gourds as a raw material, the pulp of the bitter gourds is subjected to homogenization, heat-preservation enzymatic hydrolysis, filtration, concentration and spray drying to prepare the bitter gourd instant powder, and the seeds of the bitter gourds are subjected to degreasing, enzymatic hydrolysis and ultrafiltration classification treatment to prepare the bitter gourd smallmolecule polypeptide; the bitter gourd instant powder, the bitter gourd small molecule polypeptide and the auxiliary materials are mixed to prepare the bitter gourd solid beverage with a blood glucosereducing effect through a wet-method granulation process. The prepared bitter gourd small molecule polypeptide has a blood glucose reducing effect similar to that of acarbose, and has an obvious function of inhibiting alpha-amylase and alpha-glucosidase.

Description

technical field [0001] The invention relates to the technical field of food preparations, in particular to a preparation method of bitter melon solid beverage. Background technique [0002] As a common vegetable, bitter gourd has the characteristics of high efficiency, low toxicity, and stable lipid-lowering and hypoglycemic properties. At present, bitter gourd is mainly consumed in the form of vegetables, which has a single product form and low added value; and fresh products have high moisture content, which is not conducive to storage and transportation, and is easy to breed microorganisms, resulting in short shelf life. In the existing literature, there are only studies on the extraction of active ingredients from bitter gourd pulp, bitter gourd seeds, and freeze-dried powder of bitter gourd and their lipid-lowering and hypoglycemic effects. Because the extraction process of the active ingredient of a single component is complicated, and the yield of the product is low,...
