Embodiment 1
[0031] A kind of method utilizing bean vermicelli waste water to produce high-protein solid beverage, comprises the steps:
[0032] (1) Acid precipitation: add lactic acid to the pea vermicelli wastewater, adjust the pH value to 4.3, let it settle for 30 minutes, remove the supernatant, and collect the light yellow slurry in the lower layer;
[0033] (2) Centrifugal separation: Centrifuge the collected light yellow slurry at 5000r / min for 10min to collect the lower sediment;
[0034] (3) Slurry neutralization: Add water to the sediment and mix thoroughly, adjust the pH to 7.0 with NaOH aqueous solution, and add water to adjust the concentration so that the soluble solid content of the solution is 12%;
[0035] (4) Enzymolysis: According to the ratio of 1000ml:0.1ml, add amylase to the solution obtained in step (3), and perform enzymolysis for 30 minutes at 70°C and pH value 7.0;
[0036] (5) Deenzyme sterilization: heat the liquid after enzymolysis to 90°C and keep it for 40m...
Embodiment 2
[0047] A kind of method utilizing bean vermicelli waste water to produce high-protein solid beverage, comprises the steps:
[0048] (1) Acid precipitation: Add lactic acid to the waste water from making broad bean vermicelli, adjust the pH value to 5.5, let it settle for 60 minutes, remove the supernatant, and collect the light yellow slurry in the lower layer;
[0049] (2) Centrifugal separation: centrifuge the collected light yellow slurry at 3000r / min for 15min to collect the lower sediment;
[0050] (3) Slurry neutralization: Add water to the sediment and mix thoroughly, adjust the pH to 7.0 with NaOH aqueous solution, and add water to adjust the concentration so that the soluble solid content of the solution is 16%;
[0051] (4) Enzymolysis: According to the ratio of 1000ml:0.2ml, add amylase to the solution obtained in step (3), and enzymatically hydrolyze for 40 minutes at 80°C and pH 7.0;
[0052](5) Enzyme sterilization: heat the liquid after enzymolysis to 95°C and ...
Embodiment 3
[0064] A kind of method utilizing bean vermicelli waste water to produce high-protein solid beverage, comprises the steps:
[0065] (1) Acid precipitation: Add lactic acid to the mung bean vermicelli wastewater, adjust the pH value to 4.5, let it settle for 40 minutes, remove the supernatant, and collect the light yellow slurry in the lower layer;
[0066] (2) Centrifugal separation: centrifuge the collected light yellow slurry at 6000r / min for 5min to collect the lower sediment;
[0067] (3) Slurry neutralization: Add water to the sediment and mix thoroughly, adjust the pH to 7.0 with NaOH aqueous solution, and add water to adjust the concentration so that the soluble solid content of the solution is 8%;
[0068] (4) Enzymolysis: According to the ratio of 1000ml:0.2ml, add amylase to the solution obtained in step (3), and perform enzymolysis for 20 minutes at 75°C and pH 7.0;
[0069] (5) Deenzyme sterilization: heat the liquid after enzymolysis to 90°C and keep it for 40min...
