Making method of purple sweet potato and soybean high-protein composite beverage

Abstract

The invention discloses a making method of a purple sweet potato and soybean high-protein composite beverage. The making method comprises the following steps of (1) soaking soybeans in a vitamin C solution, taking out the soaked soybeans, cleaning the taken-out soybeans with water, then adding the cleaned soybeans to water, cooking the soybeans at 100 DEG C for 2h, taking out the cooked soybeans,performing pulping, and performing filtration so as to obtain soybean milk; (2) thoroughly cleaning purple sweet potatoes, performing peeling, performing dicing, performing cooking in water of 100 DEGC for 20-50min, performing cooling, performing direct pulping, and performing filtration so as to obtain purple sweet potato juice; (3) thoroughly cleaning fructus momordicae, performing soaking in acane sugar solution of which the mass concentration is 1% for 2h, performing pulping, and performing filtration so as to obtain fructus momordicae juice; (4) mixing the soybean milk with the purple sweet potato juice and the fructus momordicae juice, performing stirring, and performing ultrasonic dispersion; (5) performing homogenizing; and (6) performing sterilization, and performing packaging.The purple sweet potato and soybean high-protein composite beverage provided by the invention is free from additives, and appropriate in sugariness, is in a uniform fluid state, and is free from precipitate, free from impurities, fine, smooth and mellow in mouth feel and high in protein content.
