preparation example Construction

[0041] The preparation method of the temperature-lowering and flavor-enhancing microcapsules provided by the present disclosure includes the following steps:

[0042] Step (1): Dissolving the wall material raw material in dichloromethane to obtain a precursor solution, wherein the wall material raw material includes polypropylene carbonate and polybutylene carbonate, and the quality of polybutyl carbonate is polycarbonate The mass ratio of the propylene ester is 30%-50%, and the mass ratio of the wall material raw material to dioxymethane is 1:(20-30).

[0043] The mass ratio of the wall material raw material and dioxymethane in step (1) can be 1:25.

[0044] Step (2): Put the content into the precursor solution, stir evenly to obtain the first solution, wherein the mass ratio of the content to the wall material raw material is 1:(2-4), and the content is nicotine and flavoring material for tobacco and at least one of natural extracts.

[0045] Step (3): mix polyvinyl alcoho...

Embodiment 1

[0058] 2g of PPC and 0.6g of PBC were dissolved in 50mL of dichloromethane, then 1g of sweet orange oil was added and stirred evenly to obtain the first solution. An aqueous solution (500 mL) of 2 wt % polyvinyl alcohol and 0.5 wt % Span 80 was added to the Soxhlet reactor, followed by the above-mentioned first solution, and the reaction was stirred at 800 rpm and 20 kPa vacuum for 3 h. After the reaction, the solid product was collected by centrifugation, washed with water, and dried to obtain sweet orange oil microcapsules.

[0059] The sweet orange oil microcapsules were added to the filter rod, and then composite rolled to obtain a four-section ( image 3 Shown) finished cigarette, wherein 60mg sweet orange oil microcapsules are added in the cigarette filter stick.

Embodiment 2

[0061] Dissolve 2g of PPC and 0.8g of PBC in 50mL of dichloromethane, then add 0.8g of apple essence, and stir evenly to obtain the first solution. An aqueous solution (500 mL) of 2 wt % polyvinyl alcohol and 0.5 wt % Span 80 was added to the Soxhlet reactor, followed by the above-mentioned first solution, and the reaction was stirred at 800 rpm and 20 kPa vacuum for 3 h. After the reaction is finished, the solid product is collected by centrifugation, washed with water, and dried to obtain apple essence microcapsules.

[0062] The apple flavor microcapsules were added to the filter rod, followed by compound rolling to obtain a four-section ( image 3 Shown) cigarette finished product, wherein add 60mg apple essence microcapsules in the cigarette filter rod.

Abstract

The invention discloses a cigarette, a cooling and aroma-enhancing microcapsule and a preparation method and application thereof. The cooling and aroma-enhancing microcapsule comprises a wall material and content, the wall material comprises polypropylene carbonate and poly (butyl carbonate), the mass of poly (butyl carbonate) accounts for 30%-50% of the mass of polypropylene carbonate, the content is at least one of nicotine, tobacco flavor and natural extract, and the mass ratio of the content to the wall material is 1: (2-4). The cooling and aroma-enhancing microcapsules are applied to the filter stick to prepare the composite filter stick, a polylactic acid film cooling unit in the prior art is replaced, and the composite filter stick is applied to heating non-combustion cigarettes, so that the processing technology is simpler, more convenient and more efficient.

Description

technical field [0001] The invention relates to the field of cigarette manufacturing, more specifically, to a cigarette, temperature-lowering and flavor-enhancing microcapsules, and a preparation method and application thereof. Background technique [0002] Existing heat-not-burn cigarettes generally have the problem of high flue gas temperature. Moreover, due to the limitation of heating temperature and insufficient cracking of tobacco substances, the release of heat-not-burn cigarettes is only about 5% of that of traditional tobacco. Therefore, heat-not-burn cigarettes still have problems such as insufficient smoke and low aroma. [0003] In recent years, the development of slow-release cooling materials has become a research hotspot in the field of new heat-not-burn cigarettes. Most of the commercially available heat-not-burn cigarette products adopt a multi-stage cigarette design to process the smoke generated by the core section. The cooling unit of the multi-stage ci...
