摘要: 以毛樱桃为原料,研究了用树脂法提取毛樱桃红色素。结果表明,AB-8树脂对毛樱桃红色素具有较高的吸附量,用50%乙醇为洗脱剂得到的产品质量好,色价高,且AB-8树脂重复使用20次后吸附率仅降低0.98%;该色素水溶性好,在酸性条件下具有较好的稳定性,有一定的耐光性,在适当温度下对热稳定性较好,对低浓度的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: The extraction of red pigment from Pruns tomentosa with resin was studied in this research.The results showed that AB-8 resin had the best performance of absorbing the red pigment.In the course of desorbing the absorbed pigment,50% ethanol was optimal.AB-8 resin was selected during the experiment.After repeating 20 times,the absorption factor was only at a loss of 0.98%.The pigment has excellent water-solubility and stability in acid solution.The light,suitable heat and low density food additions also had no obvious influences on its stability.So the pigment from Solanum nigrum might be used as a good addition.
