研究了玫瑰色素的稳定性，探讨了不同条件对玫瑰色素稳定性的影响。实验采用分光光度法，测定不同条件下玫瑰色素的特征吸收光谱的变化。确定了各种条件对玫瑰色素稳定性的影响。结果显示，玫瑰色素对温度、pH的耐受性较好，对还原剂稳定，但对氧化剂敏感，在光照条件下也不稳定。蔗糖、柠檬酸、盐等对其稳定性影响不大。因此，玫瑰色素可以作为蜂蜜、啤酒、饮料等食品的特殊风味色素添加剂。

The paper studied the stability of the rose pigment under different condition. The spectro photometry was adopted to determine the change of concentration of rose pigment. Several factors were studied for its effect on the pigment stability. The results showed that the rose pigment was unstable to oxidant and illumination, but rather stable with different temperature, pH, concentration of cane sugar, lemon and salt. Therefore, the rose dye is suitable for the specia...
