Embodiment 1
[0041] The stirring ball mill is used as the reaction device, and the ball milling reaction is carried out by mechanical solid-phase activation method. Pullulan and ε-polylysine are used as raw materials, and the mass ratio is 5:1.5. The mechanical activation time is 5 minutes and the temperature is 25°C. 1. The stirring speed is 415r / min, and the grinding medium is a stainless steel grinding ball of φ5-10mm to prepare the pullulan and ε-polylysine complex. The film-forming solution is prepared according to the ratio that the mass concentration of the compound of pullulan and ε-polylysine is 2g / 100mL, the mass concentration of gelatin is 5g / 100mL, and the mass concentration of glycerin is 1g / 100mL: Dissolve gelatin in distilled water at 80-90°C, cool to 50-60°C, add pullulan and ε-polylysine complex to dissolve, add glycerin after cooling to room temperature, stir evenly, and magnetically stir for 10 minutes. The resulting film-forming solution is poured into a polypropylene p...

[0043] The stirring ball mill is used as the reaction device, and the ball milling reaction is carried out by mechanical solid-phase activation method. Chitosan and ε-polylysine are used as raw materials. The mass ratio is 5:1.8. The mechanical activation time is 10 minutes, and the temperature is 25 ° C The stirring speed was 415r / min, and the complex of chitosan and ε-polylysine was prepared. According to the mass concentration of the complex of chitosan and ε-polylysine is 2g / 100mL, the mass concentration of gelatin is 5g / 100mL, and the mass concentration of glycerin is the ratio of 2g / 100mL to prepare the film-forming solution: first gelatin Dissolve in distilled water at 80-90°C, cool to 50-60°C, add chitosan and ε-polylysine complex to dissolve, add glycerin after cooling to room temperature, stir evenly, and magnetically stir for 10 minutes. The film-forming solution is poured into a polypropylene petri dish, placed at room temperature to form a film for 8-10 hours, and...

[0045] The stirring ball mill was used as the reaction device, and the ball milling reaction was carried out by mechanical solid-phase activation method. Dextran and ε-polylysine were used as raw materials, and the mass ratio was 5:2. The mechanical activation time was 8 minutes, and the temperature was 25°C. The stirring speed was 415 r / min, and the compound of dextran and ε-polylysine was prepared. According to the mass concentration of the compound of dextran and ε-polylysine is 3g / 100mL, the mass concentration of gelatin is 5g / 100mL, and the mass concentration of glycerin is 1g / 100mL to prepare the film-forming solution: first gelatin Dissolve in distilled water at 80-90°C, cool to 50-60°C, add the esterified compound of dextran and ε-polylysine to dissolve, add glycerin after cooling to room temperature, stir evenly, and magnetically stir for 10 minutes. The film-forming solution is poured into a polypropylene petri dish, placed at room temperature to form a film for 8-10...
