摘要
本文研究了树莓红色素的树脂法提取工艺,通过4种树脂对树莓红色素的吸附及不同浓度的乙醇对树莓红色素解吸的比较研究,结果表明,AB-8树脂对树莓红色素具有较高的吸附量,用90%乙醇为洗脱剂得到的产品质量好;产品收率达1.84%。同时,对树莓红色素的性质,稳定性也进行了研究,结果证明此色素有较高热稳定性,光稳定性及一定的抗氧化能力,具有良好的开发价值。
This article investigated the red pigment extraction of raspberry by resin, and the absorption of 4 resin by ethanol of different concentration to red pigment of raspberry. Result indicated that AB-8 resin has high absorption to red pigment of raspberry and yields high qualitative products with 90% ethanol as elute. The red pigment yield reachs 1.84. Meanwhile, the nature and stability of red pigment of raspberry were studied too. Results prove that the red pigment has high fever stability, light stability and anti-oxidant ability relatively. So it has a good development prospect.
