Embodiment 1
[0032] A preparation method of maca wine, which comprises:
[0033] Bacteria expansion culture:
[0034] Inoculate the potato medium with yeast to make the total number of bacteria reach 2×108 / mL;
[0035] Maca glutinous rice wine fermentation:
[0036] Soak the glutinous rice in water at 15-25°C for 20-30 hours, take out the glutinous rice and cook for 15-25 minutes, pour hot water above 85°C at least once during the cooking process; then mix maca powder with glutinous rice, and its maca powder The mass is mixed with the mass of glutinous rice before soaking in a ratio of 1:8 to 12; α-amylase is added to the mixture, and the amount of α-amylase added is 85 to 95 U / ml, and the temperature is maintained at 90 to 98°C at 1.5 to 1.5 U / ml. 2.5h; then add citric acid to adjust the Ph to 4.8-5.2; then add glucoamylase, after the glucoamylase is added, keep it at a temperature of 60-70°C for 1-2h; Adding the yeast cultured above, the amount of yeast added is 0.8-1.2% of the mixed ...
Embodiment 2
[0042] (1) Production of maca powder: fresh maca → wash → slice → dry → grind → maca powder
[0043] (2) Production of maca slices: fresh maca → wash → slice → maca slices
[0044] (3) Expansion culture of strains: take a loop of activated yeast and inoculate into 50 mL of potato culture medium, and culture at 30°C for 24 hours. The total number of bacteria per milliliter measured by hemocytometer was 2×10 8 individual / mL.
[0045] (4) Fermentation of maca glutinous rice wine: glutinous rice → soaking → steaming → adding maca powder and mixing → liquefaction → adjusting acidity → saccharification → sterilization → inoculation → fermentation (4d) → initial wine of maca glutinous rice.
[0046] The ratio of maca powder to glutinous rice is 1:10.
[0047] The glutinous rice is soaked in cold water at about 20°C, the room temperature is controlled at a constant temperature of 25°C, and the soaking time is 24 hours.
[0048] The cooking time of glutinous rice is 15-25 minutes, ...
