Preparation method of full-nutrient plant-based milk

The invention belongs to the technical field of novel plant-based milk, and discloses a preparation method of full-nutrient plant-based milk. According to the full-nutrient plant-based milk disclosed by the invention, an ultrasonic field treatment technology is used, and an ultrasonic hole effect and a micro-blasting effect are utilized, so that a hydrolysis process of starch macromolecules in plant seeds is regulated and controlled, and dissolution of nutrient substances such as protein, calcium ions, iron ions and zinc ions in the plant seeds is promoted. According to the invention, starch enzymatic decomposition and fat stabilization technologies are used, the prepared full-nutrient milk is completely prepared from plant raw materials, the average particle size is 19.8 microns, and the product tastes smooth and similar to milk. The chenopodium quinoa plant-based milk prepared by the preparation method has shelf stability, and layering can be effectively prevented; the protein content is 2.69%, the calcium
