Embodiment 1
[0035] Disperse 3.84g of sodium alginate in 200mL of distilled water at 60°C to form a sodium alginate aqueous solution, cool to room temperature at 25°C, add 30.00g of royal jelly, stir well to form a raw material solution; use 1% (v / v) acetic acid to adjust 500mL containing 5.05g CaCl 2The pH of the mixed solution with 2.90g chitosan was adjusted to 4.5, and 75.00g royal jelly was added, centrifuged (1000×g, 4°C, 10min), and the supernatant was taken as a gel bath. The raw material liquid is delivered to the nozzle of the high-voltage electrostatic field (8kV) through the peristaltic pump at a speed of 1mL / min. The No. 8 needle (diameter 0.8mm) with the pointed part is used as the nozzle, and the nozzle is connected to the positive stage. Vertically below and above the gel bath, a stainless steel disc with a diameter of 1cm in the middle is set as the negative electrode, which is connected to the negative electrode of the high-voltage electrostatic field. The needle of the n...

Embodiment 3
[0045] Disperse 5.00g of sodium alginate in 200mL of distilled water at 60°C to form an aqueous solution of sodium alginate, cool to room temperature at 25°C, add 30.00g of royal jelly, and stir well to form a raw material solution; use 1% (v / v) acetic acid to adjust 500mL containing 5.00g CaCl 2 The pH of the mixed solution with 3.75g chitosan was adjusted to 5.0, and 75.00g royal jelly was added, centrifuged (1000×g, 4°C, 10min) to take the supernatant as a gel bath. The raw material liquid is delivered to the nozzle of the high-voltage electrostatic field (8kV) through the peristaltic pump at a speed of 1mL / min.
