Example Embodiment
[0019] Example 1
[0020] (1) Take fresh Heibolin, remove the core, squeeze the juice, sterilize at 121℃ for 20min, cool, and filter to obtain Heibolin juice;
[0021] (2) Preparation of yeast suspension: inoculate yeast into broth medium. The specific formula of broth medium is (per liter): peptone 10g, beef extract powder 3g, sodium chloride 5g, and final pH 7. 3±0.1, culture for 48h under the conditions of 37°C and 50rpm stirring speed, take the culture solution and centrifuge at 8000rpm, and centrifuge the wet cells for use;
[0022] (3) Sodium alginate-CaCl of yeast 2 Immobilization: prepare a 4% sodium alginate solution, and then add 3% of its volume to the yeast wet cells prepared in step (2) to prepare a mixed solution, and use a peristaltic pump to pass through a 1mm aperture The needle will add the prepared mixture dropwise to 3% CaCl 2 In the solution, into a ball, and CaCl 2 The solution and the pellets were stored at -4°C for 16 hours. The pellets were taken out, rinsed...

[0032] (1) Take fresh Heibolin, remove the core, squeeze the juice, sterilize at 121℃ for 20min, cool, and filter to obtain Heibolin juice;
[0033] (2) Preparation of yeast suspension: inoculate yeast into broth medium. The specific formula of broth medium is (per liter): peptone 10g, beef extract powder 3g, sodium chloride 5g, and final pH 7. 3±0.1, culture for 48h under the conditions of 37°C and 50rpm stirring speed, take the culture solution and centrifuge at 8000rpm, and centrifuge the wet cells for use;
[0034] (3) Sodium alginate-CaCl of yeast 2 Immobilization: prepare a 5% sodium alginate solution, then add 5% of its volume to the yeast wet cells prepared in step (2) to prepare a mixed solution, and use a peristaltic pump to pass through a 4mm aperture The needle will add the prepared mixture dropwise to 6% CaCl 2 In the solution, into a ball, and CaCl 2 The solution and the pellets are stored at -4°C for 24 hours, the pellets are taken out, rinsed with ...
