Wherein, it is better that ★ represents emulsion-stabilizing performance more, and it is poorer that ☆ represents emulsion-stabilizing performance more.
Drawn by table 1 analysis, oxidation inhibitor composition is easily separated out at low temperatures, swims in emulsion surface, cannot play antioxygenation.After adopting modification oxidation inhibitor, stability of emulsion does not affect by emulsion temperature.
Table 2 compares the ageing-resistant performance of emulsion, and after emulsion dries removal moisture naturally, grind into powder puts into baking oven test, temperature 180 DEG C.
The ageing-resistant performance of table 2 emulsion
| Numbering | 0min | 5min | 10min | 15min | 20min | 30min |
| Embodiment 1 | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★☆ |
| Embodiment 2 | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★☆ |
| Embodiment 3 | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★☆ |
| Embodiment 4 | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★☆ |
| Embodiment 5 | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★★ | ★★★☆ |
| Comparative example 1 | ★★★★ | ★★★☆ | ★★☆☆ | ★☆☆☆ | Turn yellow | Redden |
| Comparative example 2 | ★★★★ | ★★★★ | ★★★☆ | ★★☆☆ | ★☆☆☆ | Turn yellow |
| Comparative example 3 | ★★★★ | ★★★★ | ★★★★ | ★★★☆ | ★☆☆☆ | Turn yellow |
Wherein, the ageing-resistant performance that ★ represents emulsion more is better, and the ageing-resistant performance that ☆ represents emulsion more is poorer.
Analyzed from table 2, when oven temperature is at 180 DEG C, it is not clearly that oxidation inhibitor plays a role in emulsion, and adopt modification oxidation inhibitor ageing-resistant performance to significantly improve, the flavescence time obviously delays.
