摘要
采用99MJ－1型蜂蜜质量检测仪，以蒽酮作为显色剂，直读测定蜂蜜中蔗糖含量．确定了样品预处理方法和葱酮用量、硫酸浓度、加热显色时间等最佳条件．检测下限0.8μg／L，摩尔吸光系数δ610＝1．980×104，在0.8～20μg／L内符合比耳定律．变异系数3．66％，回收率101．1％．
With Model 99MJ - 1 quality - testing device,anthrone as a colouring agent,one can directly read the content of the surcuose in honey,And are determined the best d conditions for the method to pretreat the honey,the concentration of anthrone and sulfuric acid. The limit of testing is 0. 8 μg/L.The Molar absorption coefficient δ640nm is 1.98 ×104. Beer's law is accorded within the range of 0. 8 to 20μg/L. The variable coefficient is 3.66%. And the recovery is 101. 1%.
