Embodiment 1
[0021] 1. Dissolve 3g of chitosan in 300g of glacial acetic acid with a mass concentration of 1.0% to prepare a chitosan solution, add 3g of cellulase (enzyme activity 500u / mg), and carry out enzymatic hydrolysis reaction at 40°C for 4 hours to obtain Modified chitosan solution;
[0022] 2. Dissolve 15g of gum arabic in 2000ml of water to prepare a gum arabic solution, add 9g of cinnamaldehyde, and emulsify and disperse at a high speed for 4min at an emulsification speed of 10000 rpm to obtain an emulsion;
[0023] 3. Add the modified chitosan solution prepared in step 1 dropwise to the emulsion prepared in step 2 (the mass ratio of gum arabic to chitosan is 1:4), stir at 30°C for 30 minutes, and carry out Agglomeration reaction; after the agglomeration reaction, add 0.75g geniposide and solidify at room temperature for 1h;
