基于电子眼和电子鼻的不同包装片烟醇化品质差异分析
Differences in aging quality of tobacco strips packaged by different methods based on electronic eyes and electronic noses
摘要
Abstract
To investigate the effects of conventional and nitrogen-filled packaging on the quality of aged tobacco strips,a rapid tobacco quality identification method based on electronic eyes and electronic noses was developed.IRIS electronic eyes and Heracles NEO ultra-fast gas-phase electronic noses were used to determine the color and volatile components of tobacco strips with different packaging methods and aging durations.The data obtained was analyzed by Principal Component Analysis(PCA)and Discriminant Factor Analysis(DFA).The results showed that:1)The main colors of two types of packaging of aged tobacco strips were similar,i.e.yellow to brown,but the nitrogen-filled packaging delayed the color browning of the tobacco strips.2)Eighteen major differential compounds including ethanol,n-propanol and pyridine were identified from the aged tobacco strips packaged by the different methods using the established volatile component fingerprints.The results of relative odor activity value(ROAV)analysis of the major differential compounds indicated that β-damascenone was a major differential aroma component in tobacco strips and myristicin was an important modifying agent.3)Both packaging method and aging time affected the aging quality of the tobacco strips.In the Guangdong warehouse,the aging rate of tobacco strips packaged by the conventional method was relatively fast,and the acetic acid and pyrazine contents increased with the aging time.The nitrogen-filled aging could improve the quality of the tobacco strips to a certain extent,but the undesirable odor compounds such as pyridine and m-xylene would accumulate due to the poor air permeability.Overall,the electronic eyes and the electronic nose techniques and their combination could quickly and effectively differentiate between tobacco strips with different packaging methods and aging time.关键词
