Preparation of low-temperature fraction for improving smoking quality and application of low-temperature fraction in cigarette heating

Abstract

The invention belongs to the technical field of heated cigarettes, and particularly relates to a preparation method of a low-temperature fraction for improving smoking quality and application of the low-temperature fraction in heated cigarettes. The preparation method comprises the following steps that tobacco raw materials comprise 25 wt% of Ru-zhou tobacco leaves in Pingdingshan of Henan Province, 15 wt% of Guizhou Anshun Pingba tobacco leaves, 25 wt% of Guangxi sun-cured yellow tobacco leaves, 25 wt% of Sichuan Sifang sun-cured red tobacco leaves and 25 wt% of Maryland tobacco leaves; and the tobacco raw materials are extracted, carbohydrates and amino acid substances are prepared, the carbohydrates and the amino acid substances are subjected to a Maillard reaction, a Maillard reaction product is filtered by a 0.1-0.3 million ultrafiltration membrane under the conditions that the temperature is room and the operating pressure is 0.16-0.18 MPa, and the obtained product is the low-temperature fraction. When the tobacco flavor disclosed by the invention is added into a heated cigarette for smoking, smoke can be obviously rounded, aroma can be improved, offensive odor can be covered, smoke plumpness and aroma components can be increased, smoking quality can be improved, and taste can be improved. Meanwhile, alkaloid is converted into a free state through Maillard reaction, and the release amount of NNK in smoke is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of heated cigarettes, and in particular relates to a preparation method of a low-temperature fraction for improving smoking quality and its application in cigarettes. Background technique [0002] According to existing literature reports, more than 6,000 chemical components have been identified in traditional cigarette gas. It can be decomposed or combined under certain conditions, so it can be seen that reducing the heating or combustion temperature can significantly reduce the release of harmful components in the smoke. In addition, the sidestream smoke generated after traditional cigarettes are lit (mainly the smoke that escapes from the smoldering end of the cigarette during the puffing interval) will cause passive smoking by non-crowds and arouse disgust among non-smokers. [0003] Smokers are eager to smoke less harmful cigarettes, and non-smokers want to avoid the hazards of passive smoking. The abov...

Problems solved by technology

[0007] In order to increase the smoke concentration and improve the smoking quality of heated cigarettes, the present invention uses natural tobacco raw materials for Maillard reaction, and then performs membrane separation to obtain low-temperature fractions to solve the problem of heavy chemical smell and controlled release of flavors and fragrances in heated cigarettes. The problem of too fast, endowing the product with a characteristic fragrance style, increasing the chemical composition of the smoke, is a new type of low-temperature spice that can obviously round the smoke, enhance the aroma, and cover up the miscellaneous gas
