Abstract

It was investigated to identify the volatile compounds of commercial vinegars by dynamic headspace sampling GLC-mass spectrometry, and additionally to evaluate the difference of sensory odor properties among vinegars such as brewed, cider, brown rice and persimmon vinegars. Thirty compounds were identified in four kinds of vinegar, which were composed of 9 carbonyl compounds, 12 esters, 6 alcohols and 3 acids. 3-Hydroxy-2-butanone could be merely detected in some of vinegar samples, and persimmon vinegar was characterized to include more various alcoholic compounds compared to the other kinds of vinegar. 3-Methyl-1-butanol was not detected from any samples of brewed vinegar, but from the most of cider, brown rice and persimmon vinegars. Persimmon vinegar has shown high strength of background odor intensity, and consequently was appeared to be inferior in background (p<0.05) and overall(p<0.01) odor preference scores to cider, brewed and brown rice vinegars.
