Fruity monomer transfer behavior analysis in wall-heated cigarettes
To quantify the aroma availability of fruity monomer fragrance materials in wall-heated cigarettes,based on gas chromatography-mass spectrometry(GC-MS)technology and olfactory sensory threshold determination,the transfer distribution,fragrance contribution,and mouth-release behavior of fruity monomer fragrances in wall-heated cigarettes were studied.The research found that:1)There is a significant difference in the fragrance contribution value(D-value)of fruity monomer fragrance materials,with the highest D-value of γ-octanolactone(12,485.0),which is 100,000 times that of benzyl alcohol(0.1);2)The mainstream smoke transfer rate of fruity monomer fragrances is not high,about 7%to 37%,but the loss of high-boiling point fragrances is mainly due to condensation entrapment,while the loss of low-boiling point fragrances is mainly due to air loss during puffing;3)The mouth-release amount of fruity monomer fragrances shows two trends with increasing puffing sequence:one is a decreasing trend,and the other is an increasing-decreasing trend.Among them,ethyl caprylate,ethyl caprate,ethyl caproate,ethyl acrylate,and ethyl benzoate show a decreasing trend,while ethyl cinnamate,γ-heptalactone,γ-octalactone,and γ-decalactone show an increasing-decreasing trend.
