Abstract
The invention provides a production method of instant nutritious purple sweet potato beverage powder. The production method of the instant nutritious purple sweet potato beverage powder comprises the following steps: (1) sorting, cleaning and peeling purple sweet potatoes; (2) cutting the processed purple sweet potatoes into small pieces being 2-3cm<3>; (3) protecting the color, rinsing and pulping by 4-6% an edible salt solution; (4) carrying out enzymolysis by 0.5-5% compound enzyme at 40-50 DEG C with the pH value being 5.0-6.0 for 1.0-1.5 hours; (5) filtering so as to obtain clear liquid, adding 2-10% of white sugar, 0.1-0.3% of citric acid, 0.1-0.3% of sodium citrate, 0.1-0.3% of pectin and 0.8-1.2% of granulesten, and blending; (6) stirring, carrying out homogenization under the pressure of 500-1000bar, controlling the feeding speed to be 5-1ml / min, and carrying out centrifugal spraying to form powder at the air inlet temperature of 160-220 DEG C and the air outlet temperature of 60-80 DEG C; and (7) packaging the powder into bags, thereby obtaining the instant nutritious purple sweet potato beverage powder. According to the production method, the process is simple; the using amount of amylase and saccharifying enzyme is low; the average relative molecular weight of the instant nutritious purple sweet potato beverage powder is relatively low; the soluble sugar is high in content, and is soluble instantly when being brewed by water; the instant nutritious purple sweet potato beverage powder is bright in color, high in nutritional value, high in market potential, and obvious in economic benefits, and has a large development space.
