【摘要】 5－羟甲基糠醛（5－HMF）是糖液受热过程中糖的分解产物。提出了用高效液相色谱法测定蔗糖溶液中5－HMF的方法，并对制糖工业中的非纯糖液，如清汁、糖浆及糖蜜等样品进行了分析。研究结果表明，5－HMF测定的线性范围为0～50mg／l，平均回收率为99．2％，最低检测浓度为0．02mg／l。更多还原

【Abstract】 5-Hydroxymethylfurfural (5 -HMF ) is a decomposition product of sugars, produced when sugar solution is heated. A HPLC method for the determination of 5-HMF in impure sugar solutions (thin juice, syrup or molasses) is proposed. The calibration curve for 5-HMF gives good linearity over the wide range of 0 ~ 50 mg/l. The average recovery of 5-HMF by the standard addition method is 99. 2 %. Limit of detection is 0. 02 mg/l.更多还原
