alpha-Dicarbonyl compounds are of major interest in food chemistry and biochemistry as important precursors of, for example, protein modifications and flavor. Due to their high reactivity most of the published structures were identified and quantitated as stable derivatives after reaction with trapping reagents. However, the present study showed for the first time that the trapping reagents are of
α-二羰基化合物作为例如蛋白质修饰和风味剂的重要前体,在食品化学和生物化学中具有重要意义。由于它们的高反应活性,大多数已公开的结构在与捕获剂反应后被鉴定为稳定的衍生物并定量。但是,本研究首次表明,捕集试剂对最终的定性和定量α-二羰基光谱具有显着影响。作为重要代表,氨基胍和邻苯二胺用于比较捕集特性并监测由Amadori化合物降解产生的二羰基结构。具有还原酮部分的二羰基结构不能被或仅被慢反应试剂如氨基胍不足以检测到。另一方面,
