Correlation analyses of the compounds in kokuto shochu and rum

Abstract

The correlation between eighty-four volatile compounds in kokuto shochu and rum were analyzed. In kokuto shochu, the compounds to indicate a correlation with fatty acid esters were acetaldehyde, 2-nonanone, n-propyl alcohol, isoamyl alcohol, and β-phenethyl alcohol; the correlations between fatty acid esters are generally high. In rum, the number of the correlations (r² ＞｜0.5｜) in industrial rum was more than that in agricol rum, and all of the correlation signs (r² ＞｜0.5｜) in industrial rum were positive. In this report, the overall trend of the compounds showing a high correlation were given consideration, and the compounds showing a higher correlation (r² ＞｜0.9｜) in rum are primarily mentioned.
