In 2018, the European Food Safety Authority reiterated the need for continued monitoring and reduction of opium alkaloid contamination on culinary poppy seeds. In this study, we propose acidic potassium permanganate chemiluminescence as an alternative detection strategy for the selective determination of morphine on poppy seeds. Six different brands of poppy seed purchased in Australia were found to contain, on average, between 21 and 210 μg/g of morphine. Seeds removed from poppy capsules within the laboratory contained significantly less morphine than those which underwent traditional industrial processing. A high-throughput sensitive flow injection analysis (FIA) method was also developed which provided results in reasonable agreement with a high-performance liquid chromatography – chemiluminescence method and a limit of quantification of 7.1 × 10−4 μg/g. Complex samples encountered in food analyses typically require separation and selectivity in one or more steps of the analytical workflow (such as sample preparation, column separation and/or detection) to improve the confidence in the determination of the target analyte. To this end, the FIA method developed here offers a simple way for industry to rapidly monitor the morphine content of poppy seeds prior to entry into the consumer market.

酸性高锰酸钾化学发光检测法提取和测定澳大利亚食品级罂粟种子表面的吗啡

2018年,欧洲食品安全局重申需要继续监测和减少烹饪罂粟种子上的鸦片生物碱污染。在这项研究中,我们建议酸性高锰酸钾化学发光作为选择性检测罂粟种子中吗啡的另一种检测策略。发现在澳大利亚购买的六个不同品牌的罂粟种子平均含有21至210μg/ g吗啡。从实验室内的罂粟胶囊中取出的种子所含的吗啡含量比经过传统工业加工的种子少得多。还开发了一种高通量灵敏流动注射分析(FIA)方法,该方法与高效液相色谱法-化学发光法和定量限为7合理地吻合。-4 微克/克。食品分析中遇到的复杂样品通常需要在分析工作流程的一个或多个步骤(例如样品制备,色谱柱分离和/或检测)中进行分离和选择性,以提高确定目标分析物的信心。为此,这里开发的FIA方法为工业提供了一种简单的方法,可在进入消费市场之前快速监测罂粟种子的吗啡含量。
