月季花色素的稳定性及对亚硝酸盐的清除作用研究

研究了月季花色素的溶解性、稳定性及对亚硝酸盐清除作用。结果表明：月季花色素不溶于非极性有机溶剂而溶于强极性有机溶剂，颜色呈棕红色；月季花色素的最大吸收波长为304nm，对光、热、还原剂不太稳定，对酸碱、氧化剂、食品添加剂比较稳定，常见金属离予中Fe^3 、Cu^2 对月季花色素有很大影响；月季花色素对亚硝酸盐具有很大的清除能力，浓度不同、反应时间不同对亚硝酸盐的清除能力有一定的差别。

Study on Stablity and Clearing Nitrite Function of Rose Flowers Pigment

The stability and nitrite clearing function of rose flowers pigment were studied.The results showed that maximunabsorption was observed at wavelength 304nm. Its stability was poor to light, while heat and reduction, while its stability wasgood to acid, alkali, oxidation and food additives. The common metal ions(except Fe3 , Cu2 )showed little obvious effects on thepigment. Moreover, it had better capability of clearing nitrite. The capability of clearing nitrite of the pigment was different withdifferent concentrations and acting time.
