example 1
[0017] 1) Wash the ripe pumpkin, peel and remove the seeds, and cut the pulp into 2-3mm slices;
[0018] 2) Blanch the pumpkin slices in 0.1% citric acid solution at 80-90°C for 5 minutes;
[0019] 3) Put the blanched pumpkin slices into a beater and crush them, add pure water until the soluble solids are 5%, and make pumpkin pulp;
[0020] 4) Add 0.2% cellulase to the pumpkin pulp prepared in step 3), enzymolysis temperature is 55°C, pH value is 3.5, enzymolysis is 1.5h, then add neutral protease 0.2%, enzymolysis temperature is 55°C , the pH value is 7, enzymatic hydrolysis for 1.5h, and finally add 0.3% α-amylase, the enzymolysis temperature is 55°C, the pH value is 7, and the enzymolysis is 1.5h;
[0021] 5) The enzymolysis solution in step 4) was inactivated at 90°C for 10 minutes, filtered to obtain pumpkin water-soluble dietary fiber extract, and set aside;
[0022] 6) Take step 5) pumpkin water-soluble dietary fiber extract 25%, xylitol 13%, preserved fruit syrup 8%,...
example 2
[0024] Example 2 is the same as Example 1, the difference is that
[0025] 4) Add 0.15% cellulase to the pumpkin pulp prepared in step 3), enzymolysis temperature is 50°C, pH value is 3, enzymolysis is 1h, then add neutral protease 0.05%, enzymolysis temperature is 50°C, The pH value is 7, enzymatic hydrolysis for 1 hour, and finally 0.1% α-amylase is added, the enzymatic hydrolysis temperature is 50°C, the pH value is 6, and the enzymatic hydrolysis is 1 hour;
[0026] 6) Take step 5) pumpkin water-soluble dietary fiber extract 20%, xylitol 10%, preserved fruit syrup 5%, citric acid 0.1%, CMC-Na 0.01%, water balance by weight percentage, deploy out beverage .
example 3
[0027] Example 3, the same example 1, the difference is,
[0028] 4) Add 0.3% cellulase to the pumpkin pulp prepared in step 3), enzymolysis temperature is 60°C, pH value is 4, enzymolysis is 2h, then add neutral protease 0.25%, enzymolysis temperature is 60°C, The pH value is 7, enzymatic hydrolysis for 2 hours, and finally 0.5% α-amylase is added, the enzymatic hydrolysis temperature is 60°C, the pH value is 8, and the enzymatic hydrolysis is 2 hours;
[0029] 6) Take step 5) pumpkin water-soluble dietary fiber extract 30%, xylitol 15%, preserved fruit syrup 10%, citric acid 0.3%, CMC-Na 0.05%, water balance by weight percentage, and deploy the beverage .
