红皮萝卜红色素性质的研究

Research on the Properties of the Red Pigment in the Red-Skin-Radish

在常温弱酸性条件下,对红皮萝卜红色素进行提取,并对其红色素性质进行研究,测定了光、热、氧化剂、还原剂、pH值及其常见金属离子Fe3+、Fe2+、Cu2+、Al3+、Ca2+等对色素性质的影响。该色素对光、热稳定性很好,适合于高温杀菌消毒的食品着色剂,具有广阔的应用前景。

Under the condition of the weak acidity and normal temperature, the red pigment of the red-skin-radish is extracted and its properties are studied to determine the influence of the light, heat, oxidizer, reducing agent, pH value and such common metal ions as Fe^3＋, Fe^2＋, Cu^2＋, Al^3＋, Ca^2＋ etc. on the property of the pigment. Such pigment remains a good stability for the light and the heat, and is suitable for the food dyeing agent which is sterilized in high temperature. And this kind of pigment has great practical prospects.
