摘要：
A coffee flavor improver of a solution that contains aroma compounds emitted in grinding roasted coffee beans, the solution being a propylene glycol solution or a combination thereof, that gives an aroma perceivable in grinding roasted coffee beans and includes in a total ion chromatogram obtained through EI mode at 70 eV using a GC/MS and using polar columns, the chromatogram has peaks for 2-methylfuran, 2-methylbutyl aldehyde, isovaleraldehyde, 2,5-dimethylfuran, 3-hexanone, 2-vinylfuran, pyridine, 2,5-dimethylpyrazine, 2-ethyl-6-methylpyrazine and 3-ethylpyridine, the ratio of the total area of all the peaks having a retention index not more than that for acetoin to the total area of all the peaks in the chromatogram, and the ratio of the total area of all the peaks having a retention index larger than that for acetoin to the total area of all the peaks in the chromatogram are fall within a specified range.
