Abstract:
Moringa stenopetala is considered a superfood due to the many bioactive compounds that it provides to the diet. However, like all edible plants, it is mandatory to guarantee food safety. Thus it is necessary to develop analytical methods that can rapidly and accurately determine hazardous pollutants, to evaluate compliance with food regulations. In this regard, two multi-component procedures were developed trying to cover some of the main organic and inorganic potential contaminants. A microwave-assisted digestion followed by electrothermal atomic absorption spectrometry was used for arsenic, cadmium, and lead determination, while a modification of the QuEChERS protocol followed by gas chromatography-tandem mass spectrometry was employed for the determination of 55 pesticides from different families. Both analytical methods were thoroughly validated according to international guidelines. The analyzed samples obtained from the Uruguayan market showed compliance with both, national and international, food regulations. The holistic approach employed in this research is not commonly presented in the literature, thus constituting a novel way to face food safety.
摘要:
辣木stenopetala被认为是一种超级食品,因为它为饮食提供了许多生物活性化合物。然而,像所有食用植物一样,保证食品安全是强制性的。因此,有必要开发能够快速准确测定有害污染物的分析方法,评估食品法规的遵守情况。在这方面,开发了两个多组分程序,试图涵盖一些主要的有机和无机潜在污染物。采用微波辅助消解,然后用电热原子吸收光谱法测定砷,镉,和铅的测定,同时对QuEChERS方案进行了修改,然后进行了气相色谱-串联质谱法,以测定来自不同家庭的55种农药。两种分析方法均根据国际指南进行了彻底验证。从乌拉圭市场获得的分析样品显示出两者的一致性,国家和国际,食品法规。这项研究中采用的整体方法在文献中并不常见,从而构成了一种新的面对食品安全的方式。
