摘要
本研究用GDZQ—聚苯胺酚树脂对甜菊甙提取液进行精制。一次离交后可得透光率>95％,铁含量<5ppm的溶液,干燥后得总甙含量>80％的白色粉末状产品。
The extract solution of stevioside is purified by GDZQ- poly- benzylaminophenol vesins. In one process, the transmittance of the extract solution obtained is over 95%and the iron content below 5ppm. More than 80% white powder products of stevioside is obtained by drying the solution.
