In this paper N-hexane is used as solvent to extract bixin,and the color value of annatto seeds with different colors of flowers andorigins under various conditions(time and way of storing,etc.
试验用正己烷作溶媒提取红木素和用紫外可见分光光度计测定吸光值的方法,对不同花色、产地的红木树种子及不同成熟度、不同贮存时间、不同贮存方法、不同原料形式等种子的色素色价进行分析比较,结果表明,其间的色素色价有明显差别:产自德宏地区的红花红木种子色素色价远高于西双版纳开红花和白花的红木树种子;种子红木素色素色价随保存时间的延长而降低;避光贮存有利于减慢种子色素的损失;种子破碎后加工会造成色素损失。
