干邑白酒具有复杂的挥发性化合物成分，有助于其感官特征。这项工作的重点是间歇蒸馏工艺，特别是专门用于干邑白兰地蒸馏的传统上分两步进行的科涅克白兰地酒蒸馏过程中通过化学反应特别产生的挥发性化合物。这项研究的目的是表征在蒸馏过程中形成的这些挥发性化合物。在典型的干邑蒸馏过程中，已对馏出液和锅炉内部进行了采样。对这些样品的分析使我们能够进行质量平衡，并指出几种类型的挥发性化合物，其数量在蒸馏过程中急剧增加。这些化合物通过其化学家族来区分。已经发现第一蒸馏步骤对于形成挥发性化合物是决定性的。此外，显示在该过程中生成了2种酯，3种醛，12种去甲肾上腺素和3种萜烯。这些结果表明，在干邑白酒中发现的一些挥发性化合物是由于高温引起的化学反应在蒸馏过程中形成的。这些发现为专业蒸馏人员提供了重要的指示，以提高产品的质量。

Evolution of Volatile Compounds during the Distillation of Cognac Spirit

Cognac wine spirit has a complex composition in volatile compounds which contributes to its organoleptic profile. This work focused on the batch distillation process and, in particular, on volatile compounds specifically produced by chemical reactions during the distillation of Cognac wine spirit, traditionally conducted in two steps with charentais pot stills. The aim of this study was to characterize these volatile compounds formed during distillation. Sampling has been performed on the distillates and inside the boiler during a typical Cognac distillation. The analysis of these samples allowed us to perform a mass balance and to point out several types of volatile compounds whose quantities strongly increased during the distillation process. These compounds were distinguished by their chemical family. It has been found that the first distillation step was decisive for the formation of volatile compounds. Moreover, 2 esters, 3 aldehydes, 12 norisoprenoids, and 3 terpenes were shown to be generated during the process. These results suggest that some volatile compounds found in Cognac spirit are formed during distillation due to chemical reactions induced by high temperature. These findings give important indications to professional distillers in order to enhance the product’s quality.
