摘要
对兰锭果色素的稳定性及影响因素进行了研究 ,结果表明 ,该色素在酸性条件下较稳定 ,但其光热稳定性较差 ,Al3+、Zn2 +、Mg2 +可提高色素的稳定性 ,而H2 O2 、VitC、Sn2 +、Fe3+、Cu2 +均大大降低色素的稳定性。黄酮、茶多酚具有辅助成色及增强色素稳定性的作用 。
The stability of pigments from Lonicera caerulea L. and influence factors on it were studied. The results showed, the pigment had higher E value and was more stable in acid condition. With the development of temperature and lighting time, the stability of pigment was obviously decreased. The improvement effect of flavonoid and tea polyphenol on the color and stability of pigment increased in accordance with their contents. In addition, Al 3+, Zn 2+and Mg 2+ could develop the pigment stability, but H 2O 2,VitC,Sn 2+, Fe 3+ and Cu 2+ decreased the stability strongly.
