Description

Preparation method of cigarette filter tip additive and application of cigarette filter tip additive in filter tip

Technical Field

The invention belongs to the technical field of cigarettes, and particularly relates to a subcritical extraction preparation method of radix glycyrrhizae snow mountain and application of the radix glycyrrhizae snow mountain in a filter tip additive.

Background

With the increasing health awareness of consumers, cigarette products must pay more attention to the requirements of low harm, safety, health and the like. In the innovation process of new cigarette products, cigarette products with low tar and low harm are developed to meet diversified demands of psychology, physiology, health and the like of consumers, reduce the harm of cigarette smoke to the health of the consumers to the maximum extent, and become the core content of tar reduction and harm reduction of cigarettes. However, in production practice, the cigarette tar and harm reduction inevitably causes the loss of the quality and quantity of partial aroma in the cigarette, so that the original smoking comfort of the cigarette is reduced, the smoking taste is distorted, the smoking throat comfort of the cigarette is slightly insufficient to a certain extent, and the 'body fluid', 'sweet' and 'moist' feelings are reduced; therefore, it is necessary to improve the smoking comfort of cigarettes and enhance the market competitiveness of cigarettes through related technologies.

Radix Glycyrrhizae in snow mountain is also called radix Gentianae Macrophyllae, radix Ginseng alba, radix Panacis Quinquefolii, radix scrophulariae, radix Glycyrrhizae, radix scrophulariae, and radix Codonopsis; lijiang na is called 'thick bow' in western language; is prepared from plants of Labiatae (Lamiaceae) genus Phlomis with thick rhizome and serial lumps; the plant is produced in inter-forest grassland, under forest or on grass slope with elevation of 2700-3000 m in Yunnan West, eastern Tibet and West of Sichuan, and is a sweet plant specially produced in Yunnan West. The Xueshan liquorice is a traditional Tibetan medicine commonly used by Tibetan nationalities in Yunnan, is used as a medicine by root blocks, and is used for treating sore throat, abdominal distension (food poisoning), stomachache, diarrhea, wind-cold type common cold and the like; has effects of clearing heat from throat, relieving cough, eliminating phlegm, invigorating stomach, and invigorating spleen. However, the subcritical extraction method of the glycyrrhiza uralensis from the snow mountain and the application of the glycyrrhiza uralensis to cigarettes are not reported.
