Abstract：In order to study the effect of alcohol-soluble extract of burley tobacco with different molecular weight on cigarette flavorings,ultrafiltration membrane with different pore sizes(3.5 ku,7 ku,8-14 ku and 25 ku)was used to separate the alcohol-soluble extract of burley tobacco,the volatile aroma components of alcohol-soluble extract and membrane separation products of tobacco were analyzed by gas chromatography-mass spectrometry(GC-MS),and the membrane separation products were evaluated for cigarette flavoring.The results showed that a total of 53 volatile aroma components were identified by GC-MS.Among them,the total volatile component content of 8-14 ku membrane separation products was the highest(113.75 mg/g),and the composition kinds was the highest(38 kinds).A comprehensive evaluation model of aroma quality was established by principal component analysis.The quality of 8-14 ku membrane separation products was the best,followed by 7 ku membrane separation products,and alcohol-soluble extract was the lowest.The results of sensory evaluation showed that 8-14 ku membrane separation products had the best aroma enhancement effect,which could reduce irritation and impurity,and improve aftertaste;Followed by 7 ku membrane separation products,which had less impurity and irritation,more comfortable aftertaste;Alcohol-soluble extract and 3.5 ku membrane separation products had the lowest sensory evaluation scores.In summary,the optimal group of alcohol-soluble extract of burley tobacco suitable for cigarette flavoring is 8-14 ku membrane separation products.
