葡萄酒行业和消费者都认为葡萄酒的香气是产品质量的重要属性。2,4,6-三氯苯甲醚存在是葡萄酒工业中的一个重要问题,因为它们的感官阈值较低。TCA,特别是2,4,6-TCA异构体,被认为是引起葡萄酒难闻气味的主要物质,也被称为“软木污染”,一些研究[1,2]。这种发霉气味来自软木塞材料,被葡萄酒消费者直接感受到,定义为类似于湿纸板、蘑菇、泥土味等[1]。在这项工作中,我们将演示在分析时间5s内直接从瓶塞中检测TCA。

INTRODUCTION
The wine industry and consumers themselves deem that wine aroma is an
important attribute of product quality. The presence of halo-anisoles is
an enological problem in wine industry because of their low sensory
threshold. TCA, particularly the 2,4,6-TCA isomer, is considered as main
substance responsible for unpleasant odour of wine also known as “cork
taint”, mentioned in some researches [1,2]. This musty, mouldy odour of
tainted wine originating from the cork material is directly detected by
consumers of wine and is defined as similar to wet cardboard, mushrooms,
earthy smell, etc [1]. In this work we will demonstrate the detection
of TCA directly from the cork stoppers in analytical time 5s.
