Abstract

Cigar is a flavor-dependent cash crop. However, the key aroma compounds of tobacco leaves are less studied. In this study, we used molecular sensory science to explore the key aroma compounds of cigar tobacco leaves from three different origins in Yunnan, China. The results showed that a total of 33 aroma compounds were quantitatively analyzed in the three tobaccos, among which there were eight key aroma components in YXYY, eight in DHYY, and four in PEYY with odor activity value (OAV)≥1 and flavor dilution (FD)≥2. Through recombination and omission experiments, the key aroma actives were further identified as phytol, acetic acid, isovaleric acid, 3-methylpentanoic acid, and (E)-5-isopropyl-8-methylnona-6,8-dien-2-one in YXYY, styrene, (E)-5-isopropyl-8-methylnona-6,8-dien-2-one, irisone, and phytol in DHYY, and acetic acid, styrene, and phytol in PEYY. In conclusion the present study revealed the key aroma compounds and their differences in cigar tobacco from three different origins. It provides insights for a comprehensive exploration of the unique flavors of cigars.

基于分子感官科学的三种雪茄烟叶关键香气成分解码。

雪茄是一种依赖口味的经济作物。然而，对烟叶主要香气成分的研究较少。在本研究中，我们利用分子感官科学对云南三种不同产地雪茄烟叶的主要香气成分进行了研究。结果表明，3种烟草共定量分析了33种香气成分，其中YXYY中有8种关键香气成分，DHYY中有8种，PEYY中有4种关键香气成分，香气活性值(OAV)≥1，风味稀释度(FD)≥2。通过重组和遗漏实验，进一步确定YXYY和苯乙烯中的主要香气活性为叶绿醇、乙酸、异戊酸、3-甲基戊酸和(E)-5-异丙基-8-甲基壬基-6,8-二烯-2- 1，DHYY中的主要香气活性为叶绿醇、苯乙烯和叶绿醇。总之，本研究揭示了三种不同产地雪茄烟叶的主要香气成分及其差异。它为全面探索雪茄的独特风味提供了见解。

期刊介绍： Frontiers in Chemistry is a high visiblity and quality journal, publishing rigorously peer-reviewed research across the chemical sciences. Field Chief Editor Steve Suib at the University of Connecticut is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to academics, industry leaders and the public worldwide. Chemistry is a branch of science that is linked to all other main fields of research. The omnipresence of Chemistry is apparent in our everyday lives from the electronic devices that we all use to communicate, to foods we eat, to our health and well-being, to the different forms of energy that we use. While there are many subtopics and specialties of Chemistry, the fundamental link in all these areas is how atoms, ions, and molecules come together and come apart in what some have come to call the “dance of life”. All specialty sections of Frontiers in Chemistry are open-access with the goal of publishing outstanding research publications, review articles, commentaries, and ideas about various aspects of Chemistry. The past forms of publication often have specific subdisciplines, most commonly of analytical, inorganic, organic and physical chemistries, but these days those lines and boxes are quite blurry and the silos of those disciplines appear to be eroding. Chemistry is important to both fundamental and applied areas of research and manufacturing, and indeed the outlines of academic versus industrial research are also often artificial. Collaborative research across all specialty areas of Chemistry is highly encouraged and supported as we move forward. These are exciting times and the field of Chemistry is an important and significant contributor to our collective knowledge.
