摘要
米团花色素是云南省某些地区居民使用的一种传统黄色天然食用色素。本研究表明 ,米团花色素在4 33nm和 32 6nm处分别有一个较强吸收峰。稳定性实验表明 :该色素对酸、热、光、氧化剂过氧化氢 (不加热 )、常见金属离子、食盐及食糖等稳定 ,但在碱性条件或亚硫酸钠存在时不太稳定。此外 ,加入过氧化氢后加热也会引起其吸光值的显著改变。初步确定米团花色素主要为胺类物质。在正常加工条件下 ,是一种较理想的天然食用色素。
The yellow pigment from the flowers of Leucosceptrum canum is a traditional food pigment in some districts of Yunan Province However,its structure and characteristics were unclear In this study,the pigment showed two absorbance peaks at 433nm and 326nm respectively The pigment kept stable under the treatment of acid,light,heat, some metal ions,salt and sugar,and its stability was not affected by hydrogen peroxide without heat treatment,but affected by alkali and reducing agent such as sodium sulfite,and also hydrogen peroxide under heat treatment The results of prelminary analysis showed that this pigment belongs to amines It will be an ideal natural pigment for the food and pharmaceutical industry
