Preparation method of tea absolute oil for cigarettes

Abstract

The invention provides a preparation method of tea absolute oil for cigarettes. The preparation method comprises the following steps: (1) tea leaves are smashed to be in the specification of 10-20 meshes; (2) an ethanol solution is added, and dynamic countercurrent extraction is performed; (3) an extracting solution is subjected to reduced pressure concentration, and a concentrated tea solution is obtained; (4) the concentrated tea solution is extracted multiple times with ethyl acetate, ethyl acetate phases are collected and subjected to reduced pressure concentration, and a tea extract is obtained; (5) ethanol is added to the tea extract, ethanol precipitation is performed, and an ethanol precipitation liquid is obtained; (6) the ethanol precipitation liquid is filtered through a ceramic membrane and subjected to reduced pressure concentration, and the tea absolute oil is obtained. The provided method is simple, efficient, energy-saving and environment-friendly; the prepared tea absolute oil has almost real and strong fragrance and can enrich the aroma of cigarettes, improve the fragrance quality and aftertaste in an oral cavity and endow the cigarettes with peculiar style characteristics after being added to the cigarettes.

Description

technical field [0001] The invention relates to a preparation method of tobacco absolute, in particular to a preparation method of tobacco tea absolute. Background technique [0002] Tea leaves mainly come from the buds and leaves of the Theaceae plant tea, which, as a medicinal and edible plant, has become an indispensable means of living in people's daily life. my country is also the earliest country in the world to cultivate, make and drink tea. The research on tea aroma and its components has a history of nearly 100 years. According to relevant literature reports, more than 600 volatile substances related to tea aroma have been identified. Although different tea varieties have different aroma types, but They all have a certain material basis, and it is precisely because of the balance between various aromas and the differences in the proportions of various aroma components that the aroma characteristics of different teas are formed. [0003] It can be seen from the cur...

AI Technical Summary

Problems solved by technology

Due to the use of high-temperature distillation, this method can easily lead to the destruction of heat-sensitive aroma components in tea leaves, which in turn affects the aroma characteristics of the final product; the patent number is: ZL201210181152.7 Tea raw materials are applied to tobacco flakes after deproteinization treatment

Although this method has undergone deproteinization treatment, the cellulose, gum and other substances still contained in it will have a certain negative impact on the smoking taste of the tobacco sheet; the patent number is: ZL201510472142. After extraction with ether, ethyl acetate and n-butanol, it is separated by normal phase chromatography column and prepared by high performance liquid chromatography to finally obtain tobacco humectant

The process is cumbersome, the product yield is low, and the amount of organic solvent is large, which is easy to cause pollution
