补充资料:紫胶色素
分子式:
CAS号:
性质:动物性天然食用色素的一种。橙黄、橙红至紫红的着色剂。其主要成分为水溶的和非水溶的二类蒽醌衍生物,包括水溶的一族紫胶酸(1accaic acid已知的有A,B,C,D,E五种组分)。可溶于水、乙醇和丙二醇。纯度愈高,水中的溶解度愈小,在酸性时,对光和热较稳定。色调随pH值而变,自橙黄色、橙红色至紫红色。在强碱性溶液中放置,则会褪色。其原料为中药材紫草茸,系紫胶虫(Laccifer lacca)在寄生的豆科、桑科等寄主植物上分泌的紫胶原胶,含色素约6.5%。加水浸泡、洗提得色浆,经酸化、除渣、加氯化钙溶液使形成色素钙沉淀,过滤、加酸再溶、过滤、结晶、精制得鲜红色紫胶色素粉末。用于饮料、糖果的着色。
