Abstract

The invention discloses a preparation method of special soybean protein particles for a liquid beverage. The preparation method comprises the following steps of dissolving soybean protein into water; regulating pH by alkali liquor; adding prolease for enzymolysis; performing heating enzyme deactivation to obtain the soybean protein hydrolysate solution; performing shearing homogenization, spray drying and sieving to obtain enzymolysis soybean protein powder; preparing spraying coating liquid: dissolving soybean power phospholipid, sucrose fatty acid ester and calcium chloride into water; performing shearing homogenization to obtain spray coating liquid; performing spraying coating granulation on the obtained enzymolysis soybean protein powder; obtaining the special soybean protein particles. The preparation process is simple; the operation is easy; the method is suitable for mass production; the prepared soybean protein particles are applied to the liquid beverage, and have the functional characteristics of good solubleness, fast dispersion, high stability, low centrifugal sedimentation rate and the like; the original flavor of the soybean protein can be remained.

Description

technical field [0001] The invention relates to a method for preparing soybean protein granules special for liquid beverages, and belongs to the technical field of food raw material processing. Background technique [0002] Protein has rich nutritional value and has the functions of improving human immunity, preventing osteoporosis, preventing cardiovascular and cerebrovascular diseases, and controlling body weight. Usually these proteins are mainly used as food raw materials in the form of powder, and then undergo further processing. In food processing and manufacturing using soybean protein powder, especially in the production of liquid beverages, it is usually dissolved in water, and the ratio of soluble protein contained in the soybean protein powder at this time (NSI: Expressed by the water solubility index of nitrogen) The higher the value, the easier it is to form a wet powder group. The wet powder group shows that after the soybean protein powder meets water, the su...
