Methods for quality control of tobacco flavor based on P&T-GC/MS fingerprinting technology
摘要
Abstract
The quality stability of tobacco flavor was comprehensively evaluated using a P&T-GC/MS fingerprinting method,which involved the integration of the angle-cosine similarity,peak matching,and multivariate T2 control charts.The findings suggested the following:The optimal pretreatment conditions for purge trapping involve a purge time of 14 minutes,a purge temperature of 40℃,and a desorption temperature of 200℃.Under this condition,the RSD of the characteristic peaks of the volatile components ranged from 1.36%to 6.98%,which indicated that the precision of the method was good.Fingerprint mapping combined with angle-cosine similarity and peak matching analysis could quickly identify tobacco flavor samples with changes in chemical components and effectively monitor the quality stability of tobacco flavor;combined with peak matching and multivariate T2 quality control charts,problems such as mismixing of samples and changes in substance content could be detected in time and the quality stability of tobacco flavor could be effectively monitored.This could help to further analyze the causes of changes in chemical components.关键词
