Embodiment 1
[0012] Take 800g of fresh purple sweet potato, wash it, peel it, and cut it into 2-3cm with a slicer 3 Small pieces, soaked in 4% salt solution for 30 minutes, rinsed with clean water, controlled to dry, took 600g and transferred to Model 79 temperature-controlled multi-purpose tissue grinder (manufactured by Jiangyin Poly Scientific Research Equipment Co., Ltd.), added 100ml of water, and controlled the temperature at 80°C Beat at high speed for 6 minutes, then cool rapidly to 20-50°C. Adjust the pH of the potato pulp to 5.5, and carry out compound enzymolysis with 8 g of α-amylase and 8 g of glucoamylase at a temperature of 40 ° C. After 1.0 h of enzymolysis, filter it with a plate and frame filter, and take the clear liquid. Weigh 40g of white sugar, 1.2g of citric acid, 1.2g of sodium citrate, 1.2g of pectin, and 4.8g of soybean lecithin into 400g of purple sweet potato clear liquid, stir with IKAW16 electric mixer at 1000rpm, and then mix with IKAT18ULTRA-TURRAX The homo...

Abstract
The invention provides a production method of instant nutritional purple sweet potato beverage powder, the steps of which are: (1) selection, cleaning and peeling of purple sweet potato, (2) cutting into 2-3 cm3 small pieces, (3) using 4-6 % salt solution for color protection, rinsing and beating, (4) enzymolysis with 0.5-5% compound enzyme for 1.0-1.5h at 40-50°C, pH5.0-6.0, (5) filter to obtain clear liquid, add sugar 2-10%, 0.1-0.3% citric acid, 0.1-0.3% sodium citrate, 0.1-0.3% pectin, 0.8-1.2% soybean lecithin for deployment, (6) Homogenize under 500-1000bar pressure after stirring, Control the feeding speed at 5-15ml / min, the air inlet temperature at 160-220°C, and the air outlet temperature at 60-80°C to carry out centrifugal spraying into powder, (7) pack into bags, and obtain instant nutritional purple sweet potato beverage powder. The invention has the advantages of simple process, less dosage of amylase and glucoamylase, low average relative molecular weight of the product, high content of soluble sugar, and instant dissolving. The product has bright color, high nutritional value, great market potential, significant economic benefits, and great room for development.
