Embodiment 1
[0024] An IgY liposome spray comprises the following components in percentage by weight: 0.5% moisturizing agent, 0.5% preservative, 1% liposome lecithin, 0.5% stabilizer, 2% IgY antibody, and the rest is distilled water. Wherein, the humectant is trehalose, the preservative is 1,2 hexanediol, and the stabilizer is Tween 80.
[0025] The preparation process of liposomal lecithin is to dissolve egg yolk lecithin and cholesterol with hot ethanol to obtain a solution, wherein the concentration of egg yolk lecithin is 10 mg / mL, the concentration of cholesterol is 2 mg / mL, and the temperature of hot ethanol is 40 ° C. The solution was sheared and homogenized for 5 minutes, followed by high-pressure homogenization. The high-pressure homogenization pressure was 30 MPa, and the high-pressure homogenization time was 7 minutes to obtain liposomal lecithin. The average particle size was 88 nm, and the PDI was 0.25. ±0.09.

Embodiment 2
[0033] An IgY liposome spray comprises the following components in weight percentage: 1% moisturizing agent, 1.5% preservative, 2% liposome lecithin, 0.8% stabilizer, 3% IgY antibody, and the rest is distilled water. Wherein, the moisturizing agent is trehalose, the preservative is hydroxyacetophenone, and the stabilizer is Tween 80.
[0034] The preparation process of liposomal lecithin is to dissolve egg yolk lecithin and cholesterol with hot ethanol to obtain a solution, wherein the concentration of egg yolk lecithin is 10 mg / mL, the concentration of cholesterol is 2 mg / mL, and the temperature of hot ethanol is 40 ° C. The solution was sheared and homogenized for 5 minutes, followed by high-pressure homogenization. The high-pressure homogenization pressure was 30 MPa, and the high-pressure homogenization time was 7 minutes to obtain liposomal lecithin. The average particle size was 90 nm, and the PDI was 0.21 ± 0.08.

Embodiment 3
[0042] An IgY liposome spray comprises the following components in percentage by weight: 1.5% moisturizing agent, 1% preservative, 2.5% liposome lecithin, 1% stabilizer, 4% IgY antibody, and the rest is distilled water. Wherein, the moisturizing agent is trehalose, the preservative is hydroxyacetophenone, and the stabilizer is Tween 80.
[0043] The preparation process of liposomal lecithin is to dissolve egg yolk lecithin and cholesterol with hot ethanol to obtain a solution, wherein the concentration of egg yolk lecithin is 10 mg / mL, the concentration of cholesterol is 2 mg / mL, and the temperature of hot ethanol is 40 ° C. The solution is sheared and homogenized, homogenized for 5min, then high-pressure homogenized, and the high-pressure homogenized pressure is 30MPa, and the high-pressure homogenized time is 7min, and the liposomal lecithin is obtained, and its particle diameter is that the average value is 90nm, and the PDI is 0.22±0.05.
