摘　　要：我国对淀粉糖浆灰分的测定一直采用灼烧质量法,实验采用电导法进行了果葡糖浆灰分测定的研究。研究表明:果葡糖浆电导灰分的最佳电导率测定浓度为25%,电导率灰分换算系数为7.93×10-4,果葡糖浆电导灰分计算公式:W灰分=7.93×10-4×(C样液-0.39×C水)。电导灰分法可以替代硫酸灰分法进行灰分的日常测定,该法对于淀粉糖生产企业具有更简便、快捷等优点。The gravimetric method is in common used for determining ash of the starch sugar in China.The determining method of high fructose syrup ash by the conductometric method is discussed in this paper.The most desirable concentration was 25grams of high fructose syrup in 100grams of solution.The conversion coefficient of the conductometric ash,7.93 ×10^-4,is given through a number of tests.The relstionship established for conductometric ash in high fructose syrup is：W 灰分=7.93×10^-4×（C 样液-0.39×C 水）.Conduc-tometric methods provide a simple,rapid and accurate means of determining ash content of high fructose syrup for industry determining,that can be used to replace the gravimetric method.
