摘要
本文比较了黑米、黑大豆、黑芝麻中天然色素的光谱特征、组成成分、理化性质等，结果表明，３种原料的色素均表现出黄酮类花色苷化合物的光谱特征吸收，都具有苯骈吡喃环的母核结构；在化学组成上均可分离出水溶和醇溶２类组分；对光、温、ｐＨ及金属离子等的反应较为敏感。
The physical and chemical properties of natural pigments in black rice,black soybean and black sesame including spectral characters,composition,photostability,thermostability,resistance to metal ions and effect of medium pH value on absorption were compared in this study.The results were as follows:3 sorts of pigment showed the same spectral absorption characters of anthocyanin with the same basic structure of phenylbenz-opyrylium,which consisted of water-soluble fraction and alcohol-soluble fraction.Light,temperature,pH and some common metal ions strongly influenced the pigment stability.
