Abstract

Abstract Gas chromatography-ion mobility spectrum (GC-IMS) is used to analyze and compare the differences in aroma among different tobacco samples. The aroma substances in tobacco samples in Jilin Changchun are the richest, while those in Guangdong Nanxiong are the lowest. The concentrations of aroma substances such as decanal, 1-hydroxy-2-propanone, and 2-methylbutanol were the highest in Guangdong Nanxiong of the three. The concentration of 1-hexanol, cyclohexanone, pentanoic acid, and other aroma substances in Fujian Nanping was high. The concentration of 2-acetylfuran, 2-octanol, isopentanol, 3-methylvaleric acid, phenylacetic acid, and other aroma substances in Changchun area of Jilin Province was low. Through principal component analysis and similarity research, both tobaccos can be distinguished by their production areas and grades from the same.

Highlights

Tobacco is considered to be a plant factory that can provide a variety of chemical components
Aroma substances in tobacco samples from different regions were analyzed by Gas chromatography-ion mobility spectrum (GC-Ion mobility spectrometer (IMS))
The red part in the atlas of JNCC and FJNP is significantly higher than the blue part, and the red part was very dark, which indicated that the content of aromatic substances in Jilin Changchun (JNCC) and Fujian Nanping (FJNP) was higher than that in Guangdong Nanxiong (GDNX)

Summary

Introduction

Tobacco is considered to be a plant factory that can provide a variety of chemical components. The traditional method is very complex, which is mainly based on liquid chromatography or the quantitative determination of organic small molecules using gas chromatography with flame ionization detection [16,17,18,19,20,21]. These methods require complex sample pretreatment process and the equipment used is very large. GC-IMS technology was used to study the contents of aroma substances in different grades of tobacco from different regions and to analyze the similarity between every sample
