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.
葡萄酒行業和消費者都認為葡萄酒的香氣是產品質量的重要屬性。2,4,6-三氯苯甲醚存在是葡萄酒工業中的一個重要問題，因為它們的感官閾值較低。TCA，特別是2,4,6-TCA異構體，被認為是引起葡萄酒難聞氣味的主要物質，也被稱為“軟木污染”，一些研究[1,2]。這種發霉氣味來自軟木塞材料，被葡萄酒消費者直接感受到，定義為類似于濕紙板、蘑菇、泥土味等[1]。在這項工作中，我們將演示在分析時間5s內直接從瓶塞中檢測TCA。
