Problems solved by technology

However, the method of directly cutting the whole dandelion herb into shreds is not easy to operate in the specific production process. The root of dandelion is not easy to cut into shreds, and the fluffy balls formed by the white pappus on the seeds are not easy to handle. The leaves of dandelion are narrow and small. The silk machine is not fully suitable, and the direct addition of dandelion plants may affect the smoking quality of cigarette products
In addition, the plant extracts produced by relatively simple and extensive extraction and processing methods often have high impurity content and poor quality stability

example 1

[0019] Take 0.8 kg of dried and crushed aerial parts of dandelion, heat them with 95% ethanol at 70°C to extract twice, the ratio of solid to liquid is 1:4 and 1:3 respectively, and a total of 4.2 kg of extract is obtained. The extract was concentrated to 617 g under reduced pressure, the vacuum degree was -0.09 MPa, and the temperature of the water bath did not exceed 50 °C. The concentrated solution was refrigerated and left to stand for 2 hours, vacuum filtered with a micron filter membrane, and the filter residue was washed with a small amount of ethanol to obtain a total of 699 g of filtrate. The filtrate after dewaxing is further concentrated under reduced pressure until it has no alcohol smell. At this time, the concentrated liquid presents two immiscible phases. It is placed in a liquid separation device and allowed to stand fully. The lower water phase is a clear dark brown liquid, and the upper layer is The oil phase is a viscous opaque liquid extract, but since the ...

example 2

[0021] 25 kg of dried whole dandelion herb purchased in the Chinese herbal medicine market, crushed to about 20 meshes; using a steam heating extraction tank with a volume of 200 L to extract twice, adding 80% ethanol 5 times and 4 times the weight of the raw material respectively, heating After the temperature stabilized to 60°C, count the time and extract for 2 hours each time; a total of 196 kg of extract was obtained. Concentrate the extract solution to 15 kg with an external circulation evaporator, the vacuum degree is -0.08 MPa, and the temperature is 40-45 °C. Put the concentrated solution in a cold storage (0-6°C) and let it stand overnight. Immediately after taking it out, use a three-legged centrifuge to dewax it, and obtain 12.8 kg of dewaxed filtrate. The filtrate was concentrated under reduced pressure using a rotary evaporator with a volume of 20 L, the vacuum degree was -0.09 MPa, and the temperature was not higher than 65 °C, and about 4 kg of the concentrated ...

Abstract

The invention discloses a method for preparing dandelion absolute oil and an application of the dandelion absolute oil in cigarettes. The method for preparing the dandelion absolute oil comprises the following steps of dandelion raw material obtaining, drying and smashing, solution extracting, extract liquid concentration, cold storage and standing, dewaxing through centrifuge, liquor concentration, freezing and standing and separation, wherein the process of liquor concentration is conducted until no alcohol smell exists, and the absolute oil is obtained after separation. The dandelion absolute oil is applied to cigarette production as spice for the cigarettes. When the cigarettes are burnt and smoked, the smoke concentration is improved, flavor is rich, foreign flavor and stimulation are reduced, and the content of parts of harmful ingredients in cigarette smoke can be reduced. The method for preparing the dandelion absolute oil is characterized in that a refined preparation technology for dandelion extract is provided, through an appropriate separation purification technology, the dandelion extract undergoes refined processing, and therefore the product quality and the effects are improved obviously. The method has the reference value for refined processing of natural spice. The method for preparing the dandelion absolute oil and the application of the dandelion absolute oil in cigarettes have the advantages that production raw materials are abundant and easy to obtain, the production technology is simple and easy to operate, the product quality is stable and easy to control, the production cost is not high, and therefore practical production significance and value are achieved.

Description

technical field [0001] The invention relates to plant extract finishing and its application, in particular to dandelion absolute and its application in tobacco. The application of this technology does not change the existing processing technology of cigarettes, can improve the smoking quality of cigarettes, and reduce the harmfulness of cigarettes. Background technique [0002] As the tar content of domestic cigarette products continues to decrease, problems such as reduced cigarette aroma, weakened style characteristics, and poor comfort have been caused to varying degrees. In order to improve the overall quality of cigarette products, it is a main solution to develop new flavors with remarkable effects and stable quality or to finely process traditional flavors. Among them, natural flavors have become the focus of research and development in recent years because of their rich fragrance, vivid fragrance, safety and environmental protection. [0003] my country is rich in ...
