Abstract

The invention relates to a cigarette alfalfa extract and a preparation method thereof. The extract is prepared through the following steps: selecting alfalfa and cutting into small sections; adding an extraction solvent and controlling temperature to perform primary extraction to separate extracting solution; then adding the extraction solvent into alfalfa residue after primary extraction and controlling the temperature to perform secondary extraction to separate extracting solution; after mixing the extracting solution obtained by the two steps, roughly filtering with a screen; adding active carbon into the roughly filtered extracting solution to decolorize; vacuuming and concentrating the decolorized extracting solution; filtering concentrated solution with a 100 nm ceramic film, wherein the obtained filtrate is the alfalfa extract. The alfalfa extract can improve the cigarette quality, has the advantages of safety and economy, can increase the amount of aroma, improve the smoke concentration, and soften and smoothen smoke, has effects of increasing smoke lasting feeling and promoting salivation, has a clear oral cavity and small stimulus and can be used as a novel cigarette flavor.

Description

technical field [0001] The invention relates to a method for preparing cigarette essence and fragrance, in particular to an extract of alfalfa for tobacco and a method for preparing the same. Background technique [0002] Alfalfa (Medicago sativa), also known as alfalfa, alfalfa or alfalfa, abroad, alfalfa, also known as buffalo herb, is part of the Papilionacae plant family. Alfalfa is widely grown all over the world. It is native to Central Asia, Western Asia, and the Eastern Mediterranean region, but was first found in Medea, Spain, Italy, and France. It is a cultivated plant in my country and is widely distributed in Northwest and North China provinces. [0003] Alfalfa is a perennial herbaceous leguminous plant of the genus Medicago. It has always been widely cultivated around the world as pasture grass for ruminants and livestock. It can also be used as a wild vegetable for human consumption. There is another record of traditional Chinese medicine: alfalfa is bitter...
