Embodiment 1

[0019] Weigh a certain amount of complex ZnCl 2 (lut) 2 , ZnCl 2 (etpy) 2 , ZnCl 2 (acpy) 2 , dissolved in ethanol after mixing, applied to the cigarette part of heat-not-burn tobacco (or reconstituted tobacco substrate or reconstituted tobacco), the application ratio of the three complexes is 0.01% of the tobacco weight. Put it into a constant temperature drying oven to balance for 24 hours . Heated to 180°C with the heating chamber for HNB tobacco, collected the flue gas with a hand-held gas sampler, and measured the chemical composition of the flue gas with a headspace GC-MS instrument. It was found that there were 3-ethylpyridine, 3,5- Lutidine, 3-acetylpyridine three aroma substances.

[0020] After the above-mentioned heat-not-burn tobacco is made, the heat-not-burn tobacco is inhaled in a non-heated state, and the gas inhaled into the mouth does not show the characteristic smell of 3-acetylpyridine, 3-ethylpyridine and 3,5-lutidine. Fragrance and bitterness; but ...

Embodiment 2

[0022] The spice 3,5-lutidine and the complex ZnCl 2 (lut) 2 Dissolved in ethanol, respectively applied to the cigarette part of the heat-not-burn tobacco (reconstituted tobacco), the dosage is 1 / 10,000 of the weight of the reconstituted tobacco, and respectively made into experimental sample and control sample heat-not-burn tobacco. Heated to 180 ℃ with the heating chamber of HNB tobacco, and smoked the smoke at the same time. It was found that the smoke of the experimental sample with the complex could experience the unique aroma of pyridine substances, and it was relatively uniform; while the flavor was applied For the control sample of 3,5-lutidine, the aroma of pyridine substances in the first puff is very prominent and bitter, and the aroma characteristics of pyridine substances decrease sharply as the number of puffs increases.

Embodiment 3

[0024] Weigh a certain amount of complex ZnCl 2 (lut) 2 , ZnCl 2 (etpy) 2 , ZnCl 2 (acpy) 2 , dissolved in ethanol after mixing, applied to shredded tobacco, the application ratio of the three complexes is 0.5% of the tobacco weight, smoked on a smoking machine after being made into cigarettes, and the total particulate matter on the Cambridge filter is extracted with ethanol, and the GC-MS The chromatograms measured by the instrument. It can be seen that the three complexes are cracked when the cigarette is smoked, and three aroma substances, 3-ethylpyridine, 3,5-lutidine and 3-acetylpyridine, are released to the particulate phase of the smoke.

[0025] After the above-mentioned cigarettes are made, smell and distinguish the smell of cigarettes, and the smell of cigarettes does not reflect the unique smell of 3-acetylpyridine, 3-ethylpyridine and 3,5-lutidine; but if 3-acetylpyridine , 3-ethylpyridine and 3,5-lutidine instead of the above-mentioned complexes, the smell ...

Abstract

The invention discloses application of a pyridine zinc complex in a tobacco product. The chemical structure formula of the pyridine zinc complex is ZnCl2(Py)2, wherein Py is pyridine, alkyl pyridine or acetyl pyridine. When the complex of pyridine type materials is applied in the tobacco product, the special fragrance characteristic of the pyridine type materials can be greatly reduced, the fragrance is soft and is not prominent, the release of the pyridine materials is continuous and stable, the pyridine type materials can be effectively released to tobacco smoke, damage during placing and storing is avoided, and the quality stability of the product can be improved. The application of the pyridine zinc complex in the tobacco product particularly solves the technical problem of the release difficulty of a pyridine type spice when tobacco is heated and not burnt.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to the application of a pyridine zinc complex in tobacco products. Background technique [0002] Pyridine aroma substances are an important class of tobacco aroma components. From the perspective of flavor release, traditional cigarettes only have a high temperature at the burning end, and the flavor release area gradually advances to the filter end as the burning end advances, so the smoke in each puff is relatively uniform; while for heat-not-burn tobacco That is to say, the entire tobacco part is placed in the heating chamber, and it is basically in a heating state of 150°C to 350°C during the smoking process. The added spices are basically released in the first 1-2 puffs, so the smoke of each puff is relatively smooth. Inhomogeneous, especially low-boiling, high-volatility fragrances. For heat-not-burn tobacco, there is a large gap between its smoke aroma and tradi...
