膨胀工艺对烟丝质量的影响

Effects expansion process on tobacco quality

以烟丝为研究对象,分别以感官评价和气质联用测定烟丝香味成分,判定不同碳膨胀工艺技术条件对膨胀烟丝物理加工质量、感官质量的影响及其变化趋势。结果表明,烟丝经不同温度二氧化碳膨胀、HT处理和塔管板烘丝后,其香味成分的变化趋势和感官质量的变化基本一致,但二氧化碳膨胀后的烟丝香味成分和感官质量降低趋势更明显。二氧化碳膨胀后烟丝的含水率有一定的提高,进而促进了烟丝膨胀效果的提高。烟丝二氧化碳膨胀最佳温度为250℃,较佳浸渍时间为120 s,烟丝填充值为6.8 cm 3/g。

To analyze the chemical composition and aroma composition of tobacco before and after expansion in order to develop a carbon dioxide expansion process for producing high-quality tobacco.The influence of different carbon expansion technology conditions on the physical processing quality and sensory quality of expanded tobacco was determined and the trend of change was determined by the single factor test method.After different temperature of carbon dioxide expansion,HT treatment and drying,the variation trend of tobacco aroma composition and sensory quality were basically the same,but the variation trend of tobacco aroma composition and sensory quality decreased more obviously after carbon dioxide expansion.The moisture content of tobacco after carbon dioxide expansion increased to some extent,which promoted the expansion effect of tobacco.The best expansion temperature of tobacco carbon dioxide was 250℃,further confirming that the better soaking time of carbon dioxide was 120 s,and the filling value of tobacco was 6.8 cm 3/g.
