Embodiment 1
[0050] (1) Litchi treatment: select 5 kg of fresh fairy lychees with nine maturity, uniform color, good shape, and no damage by diseases and insect pests, and prepare sodium chloride, sodium carbonate, sodium bicarbonate, and water at a mass ratio of 5:5:5:1000. Mixed solution, soak lychees in the mixed solution for 60 minutes to remove harmful substances, then rinse with clean water, peel off the shell, remove the core and make a pulp, add 100 mg of immobilized cellulase, mix evenly, and perform enzymatic hydrolysis while ultrasonicating. The ultrasonic power is 50w. The enzymatic hydrolysis temperature is 18°C, the enzymatic hydrolysis time is 4 hours, then squeezed, filtered with a 100-mesh sieve to obtain clarified litchi juice, and the juice yield is tested;
[0051] (2) Sterilization treatment of lychee juice: add sucrose and malic acid to lychee juice, adjust the sugar content to 20 o brix, the pH is 3.8, then add 1g of dimethyl dicarbonate, and treat at room temperatur...
Embodiment 2
[0063] (1) Litchi treatment: select 5 kg of fresh glutinous rice citrus lychees that are nine-mature, uniform in color, good in shape, and free of diseases and insect pests, and prepare a mixture of sodium chloride, sodium carbonate, sodium bicarbonate, and water at a mass ratio of 5:5:5:1000 solution, soak the lychees in the mixed solution for 53.4min to remove harmful substances, then rinse them with clean water, peel off the shell, remove the nucleus and make a pulp, add 142mg of immobilized polygalacturonase, mix well, and ultrasonically, while enzymolysis, ultrasonic The power is 61.2w, the enzymolysis temperature is 19.4°C, and the enzymolysis time is 3.2h, then squeezed and filtered with a 120-mesh sieve to obtain clarified lychee juice, and the juice yield is tested;
[0064] (2) Sterilization treatment of lychee juice: add sucrose and malic acid to lychee juice to adjust the sugar content to 21.6 o brix, pH is 3.8, then add 1.1g dimethyl dicarbonate, treat at room tem...
Embodiment 3
[0076] (1) Litchi treatment: select 5 kg of fresh Huaizhi litchi with nine maturity, uniform color, good shape, and no pests, and prepare a mixture of sodium chloride, sodium carbonate, sodium bicarbonate, and water at a mass ratio of 5:5:5:1000. solution, soak the lychee in the mixed solution for 50.4min to remove harmful substances, then rinse it with clean water, peel off the shell, remove the nucleus and make a pulp, add 172mg of immobilized pectin decomposing enzyme, mix well, and perform enzymatic hydrolysis while ultrasonicating, with the ultrasonic power of 67.6 w, the enzymolysis temperature is 20.3°C, the enzymolysis time is 2.6h, then squeezed, filtered with a 132-mesh sieve to obtain clarified lychee juice, and the juice yield is tested;
[0077] (2) Sterilization treatment of lychee juice: add sucrose and malic acid to lychee juice to adjust the sugar content to 24.4 o brix, pH is 3.8, then add 1.1g dimethyl dicarbonate, treat at room temperature for 5.1h, get ste...
