Effects of Different Redrying Methods on the Quality of Redried Tobacco Slices
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.
