【摘要】 陶坛贮存对白酒的陈酿老熟起到重要作用。通过对枝江自产浓香原酒贮存过程中的酒精度、香味物质、酒损进行连续8年的跟踪检测,结果表明,原酒在陶坛贮存过程中发生一系列的物理化学变化:酒精度逐渐降低;总酸逐渐升高,总酯逐渐降低,其中,乳酸乙酯下降最为明显;平均每年的酒损耗率达到8.17‰。本试验为研究白酒在贮存过程中的变化提供参考。更多还原

【Abstract】 Pottery jar storage plays an important role in the aging of Baijiu. Through tracking and testing of the alcohol content, aroma substances, and liquor loss of Zhijiang Nongxiang Baijiu during the eight-year storage in pottery jars, we found that a series of physical and chemical changes occurred in the liquor during the storage: the alcohol content gradually decreased; the total acids gradually increased; the total esters gradually decreased, among which the content of ethyl lactate decreased most obviously; the average annual liquor loss rate was 8.17 ‰. The final results have provided reference for the study on the changes of Baijiu during storage.更多还原
