Abstract

The invention relates to a method for preparing a tobacco extract microcapsule through supercutical fluid, and belongs to the technical field of tobaccos. The preparing method includes the following steps that tobacco leaves are subjected to supercritical CO2 extraction; an extract in a separation kettle and a wall material solution are delivered to a coaxial nozzle arranged at the top of a spraydrying tower, a tobacco extract in the extract and the wall material solution are emulsified at an outlet of the coaxial nozzle, then the product is sprayed downwards, spray drying is carried out, andthe tobacco extract microcapsule is obtained. The preparing method is easy and convenient to operate and short in preparing time, the process from extracting to microcapsule preparing is completed through one step, the stability of the product is remarkably improved, the shelf life of the product is prolonged, the preparing method can be widely used for flavoring of various tobacco products, andthe quality of flavored products is improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for preparing tobacco extract microcapsules with a supercritical fluid. Background technique [0002] As the world continues to pay attention to the health of cigarette consumers, the living environment of traditional cigarettes is becoming increasingly severe. In order to meet the needs of consumers, especially the global tobacco giants represented by Philip Morris began to develop new tobacco products as early as the 1980s Especially since 2014, with the release of Philip Morris' heat-not-burn cigarette product iqos, it has swept the global market in one fell swoop. In China, research on heat-not-burn cigarette products has also been accelerated since 2015. [0003] Heat-not-burn cigarettes deliver nicotine and the characteristic aroma of tobacco by heating but not burning tobacco, so as to achieve the smoking effect of traditional cigarettes. At the same...
