摘要:

本实验采用高效液相色谱法(HPLC)检测白酒中甜蜜素含量,获得了空白白酒以及不同甜蜜素浓度酒样的高效液相色谱图。根据甜蜜素浓度和峰面积的线性关系建立了标准曲线,并求出回归方程:y = 0.0008x+0.0147(R2 = 0.9991);对比空白酒样和添加甜蜜素的酒样,差异明显,添加甜蜜素的酒样在7~8min 时有明显的吸收峰,其中甜蜜素浓度为100μg/ml 的酒样峰面积最大,随着甜蜜素浓度的减小,峰面积也逐渐减小;将不同甜蜜素浓度的酒样进行回收率和精密度分析,得回收率范围为97.04%~115%,经重复测定,得到RSD 为4.1%,定性检测下限为1.5 μg/ml,定量检测下限为5.0μg/ml。

Abstract:

A HPLC method was developed for detect cyclamate content in liquor. The regression equation between peak area (y) and cyclamate concentration (x) was established as following: y = 0.0008x + 0.0147(R2 = 0.9991). The recovery rates cyclamate at the spiked amounts of 2 to 100 μg/ml ranged 97% to 115%, and the relative standard deviation (RSD) of 6 repeated detections was 4.1%. The limits of quantitative detection and quantitative detection were 1.5 μg/ml and 5.0 μg/ml, respectively.

Key words: cyclamate, liquor, HPLC, detection
