Preparation and adding methods of additive capable of reducing HCN and CO content of cigarettes

Abstract

The invention discloses preparation and adding methods of an additive capable of reducing HCN and CO content of cigarettes. The additive for cigarette is prepared by a stage extraction or direct water extraction method, wherein thamnolia vermicularis asahina serves as a raw material. The adding method comprises the following steps of: fully stirring and uniformly dissolving one or more of the prepared first additive, the prepared second additive and the prepared third additive in 95 percent ethanol of which the weight is 5 to 20 times that of the additive; freezing the mixture for 5 to 15 hours at the temperature of between -5 and -20 DEG C; taking out and suction-filtering the mixture to obtain a filtrate; taking the filtrate of which the weight is 0.01 to 0.05 percent of that of tobaccoshreds, and adding the 95 percent ethanol until the total weight of the ethanol and the filtrate is 2 percent of the weight of the tobacco shreds; uniformly mixing the ethanol and the filtrate; uniformly spraying the mixture onto the tobacco shreds; and balancing the tobacco shreds for 48 hours under the conditions that the temperature is 22 DEG C and the humidity is 60 percent. An active ingredient is extracted from the thamnolia vermicularis asahina with excellent effects and serves as the additive. The additive is applied to the production of cigarettes to reduce the content of harmful components, namely HCN and CO, of the cigarettes.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and mainly relates to a method for preparing a functional additive for tobacco by extracting natural plants. Background technique [0002] Snow tea has medicinal value such as promoting body fluid and quenching thirst, clearing heat and detoxifying, calming liver and reducing fire, nourishing yin and moistening lung and lowering blood pressure. Snow tea is chewed slowly, its taste turns from bitter to sweet, with endless aftertaste, and the smell effect is very fast. Lijiang snow tea is rich in genus acid, scale acid, capric acid, mannitol, amino acids, multivitamins and trace elements, and it also contains D-arabinitol and mannitol. [0003] Snow tea produced in Lijiang, Yunnan has a long history. As early as the Ming Dynasty, snow tea has become a tribute treasure of Mu’s chieftain. Now there are many companies in Lijiang that produce boxed products and beverages. It is a good gift for relativ...
