Description

A preparation method for preparing extract from herbal medicine and its application as tobacco additive

technical field

The invention relates to a method for preparing an extract from Sanqi flower and Zhuru as raw materials, and the application of the extract as an additive for cigarettes.

Background technique

Cigarettes are a special food. Generally speaking, their fragrance comes from tobacco leaves, and smoke is produced by burning and inhaling, which stimulates the smokers' olfactory organs and satisfies the smokers' physiological requirements. However, in addition to the pleasant taste substances produced by the tobacco leaves during the smoking process, it will also bring some unpleasant miscellaneous gas, astringent feeling, stimulation and so on. Therefore, cigarette companies are required to develop cigarette additives that can compensate for aroma, reduce irritation, and effectively relieve physical and respiratory symptoms caused by smoking while maintaining cigarette satisfaction. It has become one of the core competitiveness of tobacco companies.

China has extremely rich herbal resources, and many aroma components derived from herbal medicines have medicinal or health functions. The combination of different herbal aroma components can be understood as a traditional Chinese medicine compound, which has at least part of the traditional Chinese medicine compound. Panax notoginseng has significant effects of calming the liver, eliminating phlegm, and relieving asthma, and Zhuru has the effect of clearing away heat and resolving phlegm. According to the theory of traditional Chinese medicine, Zhuru can be combined with Panax notoginseng to strengthen the clearing of heat pathogens in the lungs. Introducing the combination of two flavors of herbal aroma components into cigarettes to develop functional cigarettes with special fragrance and reduced smoking hazards will have significant economic and social benefits.
