Problems solved by technology

[0003] Jujube contains organic acids, triterpene glycosides, alkaloids, flavonoids, sugars, vitamins and sitosterols, etc. Jujube is rich in citric acid, tartaric acid, malic acid and gluconic acid, etc. The extracts of jujube and jujube are A traditional flavoring for tobacco, which can correct the aroma and improve the aftertaste. Because most of their aroma substances are located in the jujube skin, and the jujube skin is dense, the traditional extraction method has poor extraction effect on the aroma substances of jujube and wild jujube. , and the impurity content is high, the dissolution effect is poor, and the use is restricted

Abstract

The invention relates to a preparation method of a jujube extract and an application thereof, belonging to the technical field of separation and extraction of active ingredients from natural products. The preparation method comprises the following steps: taking raw materials, namely red jujubes and zizyphus jujubes, removing kernels, crushing, mixing, adding cellulase for enzymolysis, increasing the temperature, performing the enzymolysis while stirring, then performing microwave extraction, centrifugation and adsorption elution, and then concentrating to get a product, namely the jujube extract, which is used as an aroma additive for cut tobacco. According to the preparation method disclosed by the invention, the enzymolysis and the microwave extraction methods are adopted, so that the extraction temperature is reduced, the extraction time is shortened, and the extraction effect is improved; the jujube extract is used as a spice for the tobacco and can enable tobacco aroma to be thick and permeable, cover miscellaneous gas and improve the quality of a tobacco product; and furthermore, the method has the advantages of uncomplicated equipment, easiness in operation and no pollution.

Description

technical field [0001] The invention relates to a preparation method and application of jujube extract, belonging to the technical field of separation and extraction of active ingredients of natural products. Background technique [0002] With the development of the economy and the improvement of living standards, people have higher and higher requirements for their hobbies—cigarette products. Aroma and taste are very important internal qualities of tobacco products. Flavoring can make up for the problems on the cigarette leaf group It can improve the aftertaste, cover up the miscellaneous gas, make the aroma of cigarettes thicker and fuller, and improve the quality of tobacco products. [0003] Jujube contains organic acids, triterpene glycosides, alkaloids, flavonoids, sugars, vitamins and sitosterols, etc. Jujube is rich in citric acid, tartaric acid, malic acid and gluconic acid, etc. The extracts of jujube and jujube are A traditional flavoring for tobacco, which can c...
