摘要
为解决目前复烤工艺存在的复烤后片烟含水率标准差大、易产生水渍烟、烟草香气物质流失、烤片机出现滴水等问题,在烤片机回潮区设置蒸汽加水复合回潮复烤、纯蒸汽直接复烤方式进行试验,研究其对烤片机烟草复烤片烟理化特性、感官特性及香气成分的影响.结果发现,与蒸汽加水复合回潮复烤相比,纯蒸汽直接复烤可以明显降低复烤片烟的含水率标准差,并明显减少水渍烟的产生,使片烟水分分布更均匀.此外,纯蒸汽直接复烤方式可以有效防止复烤片烟醇类、醛类、酯类、挥发性酸类等香气成分的流失.综合评价表明,纯蒸汽直接复烤是更优的烤片机回潮复烤方式,可以有效控制复烤加工后片烟含水率,有利于卷烟工业企业后续的仓储醇化作业,进而实现"保香提质"加工目标.
Abstract
In order to solve the problems of high standard deviation of moisture content in redried tobacco,the production of water stained to-bacco,loss of tobacco aroma substances,and dripping in the curing machine in the current redrying process,steam and water composite redry-ing,and pure steam direct redrying methods were set up in the moisture regain area of the curing machine to conduct the experiments.The effects of these methods on the physical and chemical properties,sensory characteristics,and aroma components of redried tobacco in the cu-ring machine were studied.The results showed that compared with steam and water combined moisture regain,pure steam direct redrying could obviously reduce the standard deviation of moisture content in redried tobacco,and obviously reduce the production of water stained tobacco,making the distribution of moisture content in tobacco more uniform.In addition,the pure steam redrying processing method could effectively prevent the loss of aroma components such as alcohols,aldehydes,esters,and volatile acids in redried tobacco slices.Comprehensive evalua-tion showed that pure steam direct redrying was a better way for the machine to regain moisture and redry tobacco,which could effectively con-trol the moisture content of the tobacco after redrying processing,and it was beneficial for the subsequent storage and aging operations of ciga-rette industry enterprises,thereby achieving the goal of"aroma preservation and quality improvement"processing.
