Abstract

The invention provides a preparation method for reducing the content of nicotine in a Yunnan tobacco extract refined substance. The preparation method comprises the following steps of: pretreating raw materials, shearing by a high-speed shearing machine, centrifuging by a centrifugal machine, adsorbing by macroporous resin, cleaning the macroporous resin, eluting by the macroporous resin, concentrating eluent under vacuum and the like. According to the method disclosed by the invention, the nicotine content can be obviously reduced, the nicotine content of a prepared product is reduced by 80% or more, and the contents of aroma substances such as megastigmatrienone, triethyl citrate, 3-hydroxy-beta-dihydrodamascone, phenylacetic acid, 2-oxo-alpha-ionol and the like are increased to different degrees. Moreover, the product has special fragrance different from that of a traditional Yunnan tobacco extract refined product, and the product obtained by the invention is rich in sweet fragrance, long in fragrance, rich and diversified in fragrance, mellow, natural, stable and lasting in fragrance, and good in compatibility with various spices, and can be widely applied to blending of medium-grade and high-grade essence.

Description

technical field [0001] The invention relates to the technical field of extraction and separation of plant active ingredients, in particular to a preparation method for reducing the content of nicotine in refined Yunyan extract. Background technique [0002] With the development of social economy and the improvement of living standards, people pay more and more attention to their own health. Reducing coke and harm, and reducing the harm of smoking to human body have become one of the eternal subjects of cigarette product development. It is an important spice used for flavoring cigarettes. The conventional preparation method of Yunyan refined product is that Yunyan extract is dissolved in ethanol, frozen and filtered, and concentrated under reduced pressure. [0003] However, because Yunyan extract contains nicotine, and nicotine is easily soluble in ethanol, this causes the nicotine in Yunyan extract to be transferred to the refined product of Yunyan extract substantially, so...
