A kind of tobacco extract and preparation method thereof

Abstract

The invention relates to a preparation method of tobacco extract, comprising the following steps: 1) using pectin lyase and cellulase to enzymatically treat tobacco; 2) mixing the product of step 1) with a solvent, performing ultrasonic extraction, and then Separate the supernatant from the product; wherein, the solvent contains 15-25% propylene glycol, 5-15% glycerin, 40-60% ethanol, and 15-25% water; 3) Concentrate the supernatant in step 2) under reduced pressure , concentrated until no solvent is distilled off to obtain a concentrate; 4) mix the concentrate with propylene glycol at a weight ratio of 1:1 to 5 to obtain a mixture, carry out molecular distillation on the mixture, and collect the distilled light components. The tobacco extract is used in e-cigarette liquid with improved sensory quality.

Description

technical field [0001] The invention belongs to the field of tobacco, and in particular relates to a tobacco extract and a preparation method thereof. Background technique [0002] With the increasing emphasis on smoking and health issues and the continuous strengthening of tobacco control efforts, the development environment of tobacco products has undergone major and profound changes. New tobacco products such as e-cigarettes and heat-not-burn cigarettes have developed rapidly due to their low harm and environmental impact. According to statistics, in 2017, the global new tobacco product market size was about 17.1 billion US dollars, a year-on-year increase of 38.7%. [0003] In the prior art, the e-cigarette liquid used for smoking e-cigarettes mainly uses propylene glycol and glycerin as solvents. Traditional cigarette tobacco extract aroma raw materials have problems such as low miscibility, sugar and macromolecular impurities, and easy burnt when applied to e-cigaret...

AI Technical Summary

Problems solved by technology

[0006] (2) Use a specific solvent to extract the enzyme-treated product in a targeted manner, and extract the tobacco aroma components that can be dissolved in glycerin and propylene glycol, so as to solve the problem that the general tobacco extract is difficult to dissolve evenly in the e-cigarette liquid of the propylene glycol and glycerin solvent system The problem;
