  • 摘要:

    We measured 57 items of chemical components in 76 Ginjo-shu participating in a sake contest hosted by Akita Prefecture, and analyzed whether those items in each sake may correlate with a comprehensive evaluation or the assessment of a sensory test. The analysis revealed that, although there is no correlation between a comprehensive evaluation and glucose, a significant correlation at a 0.1% level was found between the comprehensive evaluation and the following items: citric acid, succinic acid, ethyl n-caproate, i-butanol, n-butanol, ethyl acetate, proline, histidine, asparagine, glycine, threonine, cysteine, serine, ornitine, ethanol amine, and the reverse phase chromatography components (RT2. 1, RT13. 4, RT17. 6, RT21. 5, RT24. 6). We did multiple correlation analyses by establishing a comprehensive evaluation and 57 items as a target variable and an explanatory variable, respectively. As a result, a multiple correlation equation was obtained relating the comprehensive evaluation to ethyl n-caproate, proline, valine, RT17. 6, hydroxylysine, carnosine, RT21. 5, taurine, phosphoserine, and pyruvic acid. The multiple correlation coefficient was r = 0. 9028, and the contributing ratio was 81.5%.
