Embodiment 1

[0032] This embodiment provides a method for preparing temperature-controlled heat-conducting multifunctional microcapsules for cigarettes, which includes the following steps:

[0033] (1) Add 2wt% type A gelatin and 2wt% gum arabic to water at 50°C, mechanically stir and mix evenly to obtain a wall material solution;

[0034] (2) Add high thermal conductivity graphite micropowder to caprylic acid glyceride, add mass ratio of 3:10, control temperature at 50°C, add 2wt% SDS as a dispersant, mix evenly, and use it as a mixed core material;

[0035] (3) Slowly add the mixed core material into the wall material solution at a mass ratio of 1:1, add 1wt% Tween 65, and emulsify and homogenize with a high-speed homogenizer at a shear rate of 10000r / min. The shearing time is 5min to form an O / W emulsion;

[0036] (4) Keep the stirring state of 600r / min, adjust the pH of the O / W type emulsion with 10% acetic acid to be 4.0, keep the temperature at 50°C, keep the constant temperature fo...

Embodiment 2

[0040] Such as figure 1 As shown, this embodiment provides a method for preparing temperature-controlled heat-conducting multifunctional microcapsules for cigarettes, which includes the following steps:

[0041] (1) Add 2wt% ordinary gelatin and 2wt% gum arabic to water at 50°C, mechanically stir and mix evenly to obtain a wall material solution;

[0042] (2) Add γ-caprolactone to the oily solvent decyl acetate as a taste-enhancing and flavor-enhancing substance, and add a mass ratio of 1:4 to obtain an oily mixed solvent after mixing evenly. Add graphene, and oily mixed solvent The mass ratio of adding is 1:10. The temperature is controlled at 50°C, and 1wt% sodium carboxymethylcellulose is added as a dispersant, mixed evenly, and used as a mixed core material;

[0043] (3) Slowly add the mixed core material into the wall material solution, the mass ratio is 1:1, add 1wt% Tween 85, emulsify and homogenize with a high-speed homogenizer, and the shear speed is 11000r / min , t...

Abstract

The invention relates to the technical field of cigarettes, in particular to a temperature control type heat conduction multifunctional cigarette microcapsule and a preparation method thereof. According to the invention, a composite core material containing a heat conduction material and a oily solvent and a wall material are subjected to condensation and curing reaction to prepare the microcapsule, the microcapsule can be directly added in the preparation process of tobacco sheets / tobacco shreds or in a finished product, and in the low-temperature cigarette smoking process, when the temperature reaches 160 DEG C or above, the wall material of the microcapsule is successively fused and broken, and releasing composite core material is released. The heat conduction material and the oily solvent can improve the heat transfer effect, and meanwhile, the oily solvent in the composite core material and the flavor-enhancing and aroma-enhancing substance which can be selectively added can be volatilized due to heating, so that the sensory quality during smoking is enhanced.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to a temperature-controlled heat-conducting multifunctional microcapsule for cigarettes and a preparation method thereof. Background technique [0002] In recent years, heat-not-burn tobacco products are rapidly emerging as an important product in new tobacco products. The heating temperature of heat-not-burn cigarettes is generally lower than 350°C. Compared with traditional cigarettes, the amount of smoke is small, the amount of aroma is insufficient, and the taste is light. It is often necessary to add a large amount of smoking agent and flavoring substances; Poor heat transfer performance causes uneven heat transfer, resulting in less smoke and aroma release. In the prior art, commonly used heat-conducting materials are basically various carbon materials and metal materials. Compared with expensive metal materials, cheap carbon materials are more suitable. However, the colo...
