Embodiment 1

[0027] Weigh 100g of flue-cured tobacco powder and place it in a 1L Erlenmeyer flask, add 300mL of 90% ethanol, ultrasonically extract for 4 hours at an ultrasonic frequency of 40KHz and a temperature of 50°C, after standing and settling, first filter through a sand core funnel and then Filter the filtrate with a microporous membrane with a pore size of 0.45 μm, and concentrate it by rotary evaporation under reduced pressure to obtain the initial tobacco extract; the initial extract is refined and extracted by molecular distillation to obtain the final tobacco essential oil. The molecular distillation conditions are as follows: feed rate 5m L / min, vacuum degree 18Pa, sample injection temperature 80°C, heating temperature 80°C, cooling temperature 10°C, rotation speed 350r / min.

Abstract

The invention discloses a preparation method of a tobacco substrate realizing non combustion after being heated and containing microcapsule. The preparation method comprises the following steps: selecting tobacco, and preparing tobacco essential oil; diluting the obtained tobacco essential oil by adopting an atomizing agent, thus obtaining a microcapsule core; respectively weighing gelatin and Arabic gum, and respectively adding gelatin and Arabic gum into water, thus obtaining gum solutions; weighing the microcapsule core, adding the microcapsule core into the gelatin solution, carrying out emulsifying, adding the Arabic gum solution into the emulsified liquid, and carrying out emulsifying again, thus obtaining new emulsified liquid; adjusting the pH of the emulsified liquid; adding glutamine transaminase into the emulsified liquid, thus obtaining cured microcapsule, washing the microcapsule, filtering the microcapsule, and carrying out freeze drying to obtain solid microcapsule powder; and adding the solid microcapsule powder into water for dispersing, uniformly coating a tobacco substrate body with the dispersion liquid, and carrying out drying to finally obtain the tobacco substrate containing the microcapsule. The tobacco substrate provides good satisfaction for consumers, and is large in smoke amount, high in aroma concentration, and remarkable in tobacco intrinsic scent, and thus the quality of cigarettes realizing non combustion after being heated is promoted.

Description

technical field [0001] The invention relates to the technical field of tobacco, and more specifically relates to a preparation method of a heat-not-burn tobacco substrate containing microcapsules. Background technique [0002] Heat-not-burn cigarettes provide consumers with nicotine and characteristic tobacco aroma through heat-not-burn tobacco to meet consumers' needs, and at the same time can greatly reduce the release of tar and harmful substances in mainstream smoke, which is the future development of the tobacco market. important trends. The design of heat-not-burn tobacco raw materials is very different from that of traditional cigarettes. Relevant experiments have shown that ordinary cigarettes without special treatment cannot provide satisfactory smoke volume and aroma when used in ordinary smoking utensils. [0003] The patent document with the application publication number CN103181613 provides a method for preparing electric dry distillation tobacco sheet. In th...
