Embodiment 1
[0015] A preparation method of cherry ferment is completed according to the following steps:
[0016] 1. Pre-treatment: clean the ripe cherries, remove pits, and beat;
[0017] 2. Enzymolysis: Mix cherry pulp and water 1:2, add 0.07% 480U / g xylanase and 0.08% 500U / g Novozyme enzyme, enzymolyze at 56°C for 2.5h, and collect the enzyme by centrifugation Solution;
[0018] 3. Substrate preparation: measure the soluble solid content of the enzymolysis solution, add sucrose to make the solid content reach 18%, then add 0.2% yeast extract, 0.1% magnesium sulfate, 0.05% dipotassium hydrogen phosphate, 0.05 % potassium dihydrogen phosphate, 0.1% zinc chloride, to obtain fermentation substrate;
[0019] 4. Fermentation: Heat the fermentation substrate at 100°C to sterilize for 21 minutes, cool to room temperature, inoculate with 0.1% yeast, ferment at 30°C for 12 hours, then inoculate with 0.05% lactic acid bacteria, ferment at 37°C for 27 hours, and finally inoculate at 7°C After f...
