3-Dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (DDMP) exists in many foods, and its effect on taste is controversial. The aim of this study was to clarify whether DDMP has bitter taste or not. For this purpose, DDMP was synthesized from maltol instead of from glucose for the first time. In contrast, DDMP derived from glucose was also prepared and further purified. Their structures were identified
2,3-二氢-3,5-二羟基-6-甲基-4 H-吡喃-4-酮(DDMP)存在于许多食品中,其对味道的影响是有争议的。这项研究的目的是澄清DDMP是否具有苦味。为此目的,DDMP首次由麦芽酚而不是葡萄糖合成。相反,还制备了源自葡萄糖的DDMP,并进一步纯化。它们的结构通过NMR和MS鉴定,并且被认为是相同的物质。感官分析表明,源自麦芽酚的DDMP无味。进一步的研究表明,美拉德反应中的一些杂质使DDMP产生了葡萄糖味苦味。
