Abstract

The invention discloses a method of producing a high protein solid drink by utilizing bean vermicelli wastewater. The method comprises the following steps of: (1) carrying out acid precipitation, that is to say, adding lactic acid into bean vermicelli production wastewater, standing and precipitating, removing supernate, and collecting lower layer of faint yellow size; (2) centrifuging and separating; (3) carrying out size mixing and neutralizing; (4) carrying out enzymatic hydrolysis; (5) deactivating enzyme and sterilizing; (6) dosing; (7) heating and homogenizing; (8) spraying and drying; and (9) pelletizing and refining, that is to say, spraying and drying to obtain a powdery product, and pelletizing and screening in a dry environment to obtain the high protein solid drink with uniform particles, a protein content of more than 12% and a moisture content of less than 5%. The high protein solid drink, prepared by the invention, has good solubility, smooth taste and strong smell. According to the method, provided by the invention, after the protein is directly extracted by the bean vermicelli wastewater, the high protein solid drink is processed, the process flow is simple, the comprehensive utilization rate of bean raw materials can be greatly improved, and the economic benefit of an enterprise is increased.

Description

technical field [0001] The invention relates to a method for producing a high-protein solid beverage, in particular to a method for producing a high-protein solid beverage by using wastewater from bean vermicelli, and belongs to the technical field of deep processing of agricultural by-products. technical background [0002] The raw materials for the production of bean vermicelli mainly include peas, broad beans, and mung beans. As a traditional industry in my country, vermicelli production has a long history and there are many manufacturers, including large-scale enterprises with a high degree of mechanization, and small urban and rural workshops with manual operations. However, regardless of the scale, the starch in the bean raw material is used to make vermicelli, and the protein accounting for 20% to 25% of the raw material weight is not well utilized, and it is all discharged with the waste water and residue produced, which pollutes the environment. It also wastes prec...
