Embodiment 1
[0038] Wash and dry 1 kg of purple corn kernels and crush them until they can pass through a 60-mesh sieve. Soak the crushed raw materials in 14 L of water for 1 hour, place the soaking liquid in a constant temperature water bath at 98°C for 30 minutes, and cool it to room temperature. Add 1000U of medium-temperature α-amylase to the medium temperature water bath at 50°C for 20 minutes, adjust the pH value of the enzymolysis solution to 4.5, add 400000U glucoamylase in a constant temperature water bath at 60°C for 4 hours, and sieve the obtained enzymolysis solution with a 180-mesh filter Net filtration, the filtrate was filtered using a 50nm ceramic membrane at a constant temperature with a transmembrane pressure of 0.3MPa to obtain 13.5kg of filtrate, the amount of white sugar added was 0.27kg, citric acid 16.2g, CMC4.05g, sodium alginate 6.76g, 0.6 Degas under MPa pressure, sterilize at 130°C for 5s, and fill. The above process can refer to figure 1 As shown in the flow ch...
Embodiment 2
[0040] Wash and dry 1kg of purple corn grains and crush them until they can pass through a 60-mesh sieve. Soak the crushed raw materials in 6L of water for 1 hour, place the soaking solution in a constant temperature water bath at 60°C for 40 minutes, and cool to room temperature. Add 2000U of medium-temperature α-amylase in the medium-temperature water bath at 50°C for 60 minutes, adjust the pH value of the enzymolysis solution to 4.5, add 200,000U glucoamylase in a constant-temperature water bath at 60°C for 4.5 hours, and pass the obtained enzymolysis solution through an 80-mesh filter Filter the filtrate with a 200nm ceramic membrane and filter it at a constant temperature with a transmembrane pressure of 0.2MPa to obtain 5.6kg of filtrate, with the addition of 0.168kg of white sugar, 7.28g of citric acid, 2.24g of CMC, and 2.8g of sodium alginate. Degas under 0.6MPa pressure, sterilize at 130°C for 5s, and fill. The above process can refer to figure 1 As shown in the flo...
