Embodiment 1

[0027] Perilla scape has the herbal aroma of perilla. It is an important heat-not-burn cigarette additive. It can make the smoke soft and delicate, make the aftertaste pure and comfortable, and can obviously improve the smoke quality. Heat-not-burn cigarette rods were added with 0.1% perilla scape, kept at 22°C and 45% relative humidity for 48 hours, and smoked with a single-channel smoking machine with a suction volume of 60 mL and a suction duration of 1 s. The puffing interval is 100 s, and the puffing curve is bell-shaped; the smoke is diluted (dilution factor 500 times) and then introduced into the ELPI, and the 12-stage filter membrane pre-equipped on the ELPI is used to capture the cigarette smoke aerosol. 2 cigarette smoke aerosols; then place each stage of filter membrane in 12 10mL glass bottles, add 10.0 mL of dichloromethane solution in turn, ultrasonically extract for 5 min, take it off, and extract the solution through a 0.22 μm organic phase micro-membrane Filtr...

Embodiment 2

[0032] Palmitic acid is a flavoring additive for heat-not-burn cigarettes, which has the effect of making the smoke soft and delicate. Add 0.5% palmitic acid to heat-not-burn cigarette rods, equilibrate at 25°C and 44% relative humidity for 60 hours, and smoke cigarettes with a single-channel smoking machine with a suction volume of 20 mL and a suction duration of 4 seconds. The puffing interval is 60 s, and the puffing curve is bell-shaped; the smoke is diluted (100 times the dilution factor) and then introduced into the ELPI, and the 12-stage filter membrane pre-equipped on the ELPI is used to capture the cigarette smoke aerosol, capturing 20 Cigarette smoke aerosol; then put each filter membrane in 12 10mL glass bottles, add 2.0 mL ethanol solution in turn, ultrasonically extract for 10 min, take it off, filter the extraction solution through a 0.22 μm organic phase micro-membrane, add Deuterated palmitic acid internal standard solution, then measured by GC-MS to obtain the...

Embodiment 3

[0037]Eugenol has a strong clove aroma and is an important flavoring ingredient in heat-not-burn cigarettes. Heat-not-burn cigarette rods were added with 0.005% eugenol, equilibrated at 30°C and 60% relative humidity for 40 hours, and smoked with a single-channel smoking machine with a suction volume of 100 mL and a suction duration of 2 s. The puffing interval is 30 s, and the puffing curve is square; the smoke is diluted (dilution factor 2000 times) and then introduced into the ELPI, and the 12-stage filter membrane pre-equipped on the ELPI is used to capture the cigarette smoke aerosol. 15 cigarette smoke aerosols; then each level of filter membrane was placed in 12 10mL glass bottles, 25.0mL ethanol solution was added in sequence, ultrasonically extracted for 20 min, removed, and the extraction solution was filtered through a 0.22 μm organic phase micro-membrane, Add deuterated p-cresol internal standard solution, and then measure by GC-MS to obtain the concentration of eu...

Abstract

The invention relates to a method for measuring distribution of perfume of a heat-not-burn cigarette in smoke aerosol having different particle sizes, and belongs to the technical field of novel tobacco product perfuming. The method includes adding perfume into the heat-not-burn cigarette; suctioning the cigarette according to a required suction mode; capturing particles having different particlesizes in cigarette smoke aerosol by utilizing an electronic low-pressure impactor (ELPI); performing treatment; and then measuring perfume by adopting a gas chromatograph-mass spectrometer (GC-MS) toobtain a distribution situation of the perfume in cigarette smoke having different particle sizes. The method provides technical support for development of a perfume formula and accurate perfuming ofthe heat-not-burn cigarette.

Description

technical field [0001] The invention belongs to the technical field of flavoring of novel tobacco products, in particular to a method for measuring the distribution of heat-not-burn cigarette spices in smoke aerosols with different particle sizes. Background technique [0002] Heat-not-burn cigarettes heat tobacco containing atomizers by means of charcoal heating, electric heating, etc., and components such as smoking agents and flavors in tobacco sublimate and condense to produce aerosols. The flavors in them determine the sensory quality of the smoke. At present, relevant researchers have shown that the chemical composition of different properties in aerosols will have different distributions depending on the size of the aerosol particles, and aerosol particles with different particle sizes enter the respiratory system and deposit in different parts, such as residues in the mouth, nasal cavity and lungs. Most of the large-size aerosol particles remain in the mouth and nasa...
