Abstract

The invention relates to the technical field of natural plant protein solid beverage and particularly relates to a preparation method of fermented walnut soy protein nutrition powder. The preparation method comprises the steps of drying; crushing; adding water and uniformly stirring, sterilizing; adding sugar, skim milk powder and mixed strains, and fermenting; adding a surface active agent and uniformly mixing; and adding dextrin, and spraying and drying. According to the preparation method provided by the invention, the utilization ratio and the processing depth of walnut meals and soybeans are increased, and wrappers and bean dregs in the walnut meals are effectively utilized. According to the preparation method provided by the invention, the simplicity, time saving and labor saving are achieved, the walnut soy protein nutrition powder prepared by the method is high in nutritive value, fine and smooth in mouthfeel, low in cost, cheap, convenient to use, carry and transport, easy to store, long in storage life and can not go bad easily and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of natural plant protein solid beverages, in particular to a preparation method of fermented walnut soybean protein nutrition powder. Background technique [0002] Walnut soybean protein nutrition powder is a new type of health-care and nutritional solid beverage made of walnut meal and soybean as the main raw materials, using bioengineering and fermentation technology. Walnuts are rich in nutrition, edible and medicinal, and rich in amino acids and fatty acids. After the walnuts are cold-pressed, the protein content in the walnut meal reaches more than 40%, the essential amino acid content is high, and it also contains essential phosphorus, magnesium, calcium and other minerals and vitamins A, B, C, E, and zinc , manganese, chromium and other indispensable trace elements for the human body, without cholesterol, is an excellent food raw material. However, walnut meal after cold pressing is generally used...
