[0048] Embodiment 11 Preparation of Nanoemulsion
[0049] Capsicum oleoresin and Tween 80 were mixed in different mixing ratios (1:3, 1:4, 1:5) and stirred at 150 rpm for 3 minutes. Add chitosan solution to this mixed solution with different addition ratios (0.2%, 0.4%, 0.6%, 0.8%, 1.0%) and stir 3 minutes under the above-mentioned rotating speed, react 1 minute in the water bath of 50 ℃ then, thereby A mixture is produced. Using an ultrasonic device (sonic dismembrator Model 500, Fisherscientific, USA), the mixture was sonicated at 45% amplitude, 3OW and 4°C for 3 minutes to generate an oil-in-water (O / W) nanoemulsion. The addition ratio herein refers to the addition content of capsicum oleoresin and Tween 80 relative to the total amount of chitosan solution. For example, the addition ratio of 0.4% refers to the addition of chitosan solution 100ml in 0.4g of capsicum oleoresin:Tween 80=1:4 mixed solution. Same as above.

[0054] Embodiment 31 The influence of the mixing ratio of capsicum oleoresin / Tween 80
[0055] After heat treatment at 75°C, the particle diameters of the nanoemulsions prepared by the mixing ratios of capsicum oleoresin and Tween 80 of 1:3, 1:4 and 1:5 were measured by the aforementioned method. As the mixing ratio of Tween 80 increased, the size of the nanoemulsions was small, but various nanoemulsions prepared by making the mixing ratio of capsicum oleoresin and Tween 80 1:4 and 1:5 formed a size of 52.1 nm and 13.32nm homogeneous and stable nanoemulsion.
[0056] The stability of the nanoemulsion after heat treatment at 75°C for 15 minutes increases with the mixing ratio of Tween 80. The particle diameter of the nanoemulsion prepared by making the mixing ratio of capsicum oleoresin and Tween 80 1:5 was 16.06 nm, but there was little difference between the particle diameter and the particle diameter before heat treatment. However, the particle size of the nanoemulsion p...

[0057] Embodiment 41 Storage stability with the addition ratio of capsicum oleoresin / Tween 80
[0058] Nanoemulsions were prepared by mixing capsicum oleoresin and Tween 80 in a mixing ratio of 1:4 with 0.2% by weight chitosan solution at addition ratios of 0.2%, 0.4%, 0.6%, 0.8%, and 1.0%, and then The nanoemulsion was stored at 25°C for 7 days. Thereafter, the particle diameter of the nanoemulsion was measured by the method described above. However, an unstable emulsion was formed at an addition ratio of 0.2% and the particle size of some nanoemulsions changed during storage, but a stable emulsion was formed at an addition ratio above 0.4% ( Figure 4 ).
