Abstract
Non-glucosidic cyanogen, which easily break down to liberate toxic cyanide ions, present in sorghum, wheat and fermented grains involved in Chinese liquor fermentation affect its quality and safety, and may endanger public health. In this study, a simple and practical method for the determination of non-glucosidic cyanogen was developed using QuEChERS sample-preparation, combined with spectrophotometry. The QuEChERS extraction solvent, buffer and SPE adsorbents were varied to optimize analyte recovery from spiked samples. Under the optimum conditions, the linear range for cyanide determination was 0.02–0.44 μg/mL, with a correlation coefficient of 0.99 and an LOD of 0.0023 μg/mL. The recoveries of spiked sample (82.11–115.12%) and the relative standard deviations (RSDs; 4.87–9.62%) were considered satisfactory. The method was successfully applied to real samples and was simple, efficient, inexpensive, practical and reliable.
