美拉德反应以重要方式影响加工食品中风味和颜色的形成。还原糖和氨基酸最终会与稳定的最终产物发生反应。为了阐明复杂的形成途径,已经发表了大量实验。α-二羰基化合物被认为是重要的关键中间体。在目前的工作中,对赖氨酸存在下的美拉德葡萄糖降解进行了重新研究。用邻苯二胺捕获α-二羰基化合物,得到稳定的d-阿拉伯-己基-2-己糖(葡糖酮),N 6-(3,6-二脱氧己基-2-ulos-6-基)-1-赖氨酸的喹喔啉,1-deoxy- d - erythro-2,3-己二糖(1-脱氧葡糖酮),3- deoxy- d-赤-己基-2-ulose(3-脱氧葡糖酮),乙二醛(乙二醛),2-氧丙醛(甲基乙二醛),3,4-二羟基-2 -oxobutanal(苏糖松),1-hydroxy-2,3-butanedione(1-deoxythreosone),4-hydroxy-2-oxobutanal(3-deoxythreosone),4
