Effect of Propylene Glycol and Its Polymer in Cut Tobacco as Humectant

Abstract:

In order to find new tobacco humectants，taking Propylene glycol as a control，we studied the effects of PPG and（PG+PPG） group on the moist-keeping and humidity resistance of cut tobacco. The results indicated that PG+PPG400 had better moist-keeping and humidity-resistant effects than propylene glycol under the conditions of RH（40±2）% and RH（80±2）% ，respectively. PG+PPG400 had more advantageous to the improvement of sensory quality（especially aroma and comfort） of cigarette than propylene glycol. The pyrolysis test for PPG400 at 650℃ showed that its cleavage products contained a variety of aroma components in cigarette smoke and some special flavorous ketone and alcohols compounds.
