Embodiment 1
[0023] 1. Formula
[0024] The raw materials used are as follows: curdlan gum 5g, berberine 5g, asiaticoside 1g, astaxanthin 1g, steviol glycoside 0.08g, vitamin B2 6g, water 100ml.
[0025] 2. Preparation method
[0026] Weigh 5g of curdlan, add it to 100ml of water, and stir on a high-speed mixer at room temperature to form a stable suspension;
[0027] Weigh berberine, asiaticoside, astaxanthin, steviol glycoside and vitamin B2, add to curdlan gum suspension, stir and mix at 50°C to form a uniform dispersion;
[0028] The prepared dispersion was spread on a polytetrafluoroethylene plate, and dried in a 90°C drying oven for 3 hours to form a film;
[0029] The prepared film was irradiated under ultraviolet light for 15 minutes on the front and back sides respectively, and the package was sealed.
