Abstract

The invention discloses burdock root ethanol extract and the application thereof in tobacco. The preparation process of the burdock root ethanol extract comprises the following steps that a, burdock root is subjected to impurity removal and is cleaned and sliced; b, the slices are dried under the temperature of 30-60 DEG C; c, the slices are smashed to realize the mesh of 10-100; d, ethanol is added to the smashed burdock root; e, the smashed burdock root is subjected to ultrasonic extraction for 45-75 minutes; f, the smashed burdock root is filtered, and filtrate is kept; g, the filtrate is concentrated, the volume after concentration is one seventh to one fifth of the volume before concentration, the burdock root ethanol extract is prepared and stored in the normal temperature. The application of the burdock root ethanol extract in tobacco comprises the following steps: a, the burdock root ethanol extract is sprayed to tobacco shreds, the weight of the concentrated solution is 0.1%-0.2% of the weight of the tobacco shreds; b, the tobacco shreds are processed into cigarette finished products. The burdock root ethanol extract and the application thereof in tobacco have the beneficial effects that the smoking quality of the cigarettes is improved under the condition that the original property of the cigarettes is not changed.

Description

technical field

[0001] The invention relates to a plant extract and its application in tobacco, in particular to a burdock root ethanol extract and its application in tobacco. Background technique

[0002] Burdock is a biennial herb of the Compositae family. It is a good homologous plant for medicine and food. It contains a variety of biologically active substances. It is widely used in the pharmaceutical industry. It is reported that the fructan extracted from burdock root has strong antitussive effect according to the activity study, which is equivalent to the non-narcotic cough suppressant commonly used in clinical practice. The research of burdock in China is mainly in the aspects of chemical composition determination, medical treatment, comprehensive processing and utilization.
