Problems solved by technology

And the main characteristic composition of clove is eugenol, adopts existing preparation method to obtain the content of eugenol the highest can only reach 85%, and its purity is lower
In addition, a good spice extraction method provides the basis for essence purification, while the general volatile oil extraction method, namely steam distillation, requires high temperature, which will cause the heat-sensitive substance eugenol in the essential oil to deteriorate.
Therefore, it is necessary to choose an extraction method that can extract in a low temperature environment and ensure sufficient extraction, and can effectively obtain high-purity eugenol. However, there is currently no better method that can achieve the above effects

Abstract

The invention provides a microcapsule double-aqueous-phase extraction method of tobacco clove oil, and applications thereof. The extraction method comprises the following steps: putting cloves into an ultrasonic extraction device, performing ultrasonic extraction by adopting an ethanol water solution as a solvent to obtain a clove extracting liquid, filtering, and adding a cyclodextrin capsule wall material and inorganic salt or inorganic base, evenly stirring and standing and layering; filtering and separating a cyclodextrin microcapsule layer, adding absolute ethanol into the cyclodextrin microcapsule layer and stirring for 30-60 min, and releasing a capsule core; and then filtering and separating the mixed solution to obtain an ethanol layer, and performing decompression distillation until no ethanol is distilled, thus obtaining the tobacco clove oil. The purification method is simple, mild in conditions, and environment-friendly, the purified clove oil selectively retains the characteristic component eugenol of cloves, another two main components, eugenol acetate and caryophyllene, obtained through common vapor distillation can be removed, the invention provides a method for separating and purifying eugenol from clove oil, and the eugenol is used for covering up miscellaneous gas in a cigarette and improving the aroma quality.

Description

technical field [0001] The invention relates to a method for preparing cigarette essence and fragrance, in particular to a microcapsule aqueous two-phase purification method and application of clove oil for cigarettes. Background technique [0002] Clove is an evergreen tree belonging to the genus Myrtaceae. Clove oil has a special and strong spicy aroma, and is widely used in food additives, tobacco, flavoring agents and other fields. Clove oil is an important raw material for blending spicy and sweet aromas in tobacco flavors, and can enhance the pleasant flavor of tobacco. [0003] Generally, clove oil is prepared by steam distillation, but when clove oil is extracted by conventional steam distillation, since the specific gravity of clove oil is close to that of water, the collected volatile oil and water cannot be separated well, so it is generally necessary to use organic solvents such as petroleum ether Carry out further extraction, extraction process is complicated, ...
