摘要: 以马樱杜鹃花为原料,用树脂法提取马樱杜鹃花红色素,并对其理化性质进行研究。结果表明,HPD-200树脂对该色素具有较高的吸附量,用75%乙醇为洗脱剂得到的产品质量好、色价高,且HPD-200树脂重复使用20次后吸附率仅降低1.4%;该色素在酸性条件下具有较好的稳定性,并且对光、热和常用食品添加剂比较稳定,是一种价廉易得、安全可靠、使用方便的天然植物色素,在食品工业中有一定的开发利用价值。

Abstract: A red pigment was extracted from Rhododendron delavayi Franch by resins method,and its characteristics were studied. The results showed that HPD-200 resin has the best performance of absorbing the red pigment. 75% Ethanol solution is optimal for desorbing the adsorbed pigment. After being used for 20 times repeatedly,the adsorption rate of HPD-200 resin is only at a loss of 1.4%. The pigment is stable to acidity,light,heating and common food additives. As a natural plant pigment from Rhododendron delavayi Franch,it has high value of development and utilization for the characteristics of low cost and easy availability,safety and reliability as well as convenience to use.
