[0024] Example 1 Preparation of jujube fragrance base

[0025] 1) Jujube pretreatment: select high-quality jujube varieties from Xinzheng to remove mildew and moth-eaten fruit; rinse repeatedly with running water to remove the sediment and impurities attached to the surface of the jujube; drain the cleaned jujube and dry at 60°C Bake for 1 hour, then bake at 80-90°C until the jujube gives off a burnt aroma, take it out to cool, remove the core, and cut into granules for later use;

[0026] 2) Ultrasonic extraction: Weigh 1000g of jujube granules, add 50% ethanol three times its weight, and ultrasonicate for 1 hour at 50-65°C with 100% power, repeat the extraction twice, combine the two filtrates, and set aside;

[0027] 3) Concentration of jujube extract: Concentrate the jujube extract with a vacuum rotary thin film evaporator, in which the temperature of the water bath is 50°C, the pressure is 0.095Mpa, and concentrated to 30-35 degrees Baume to obtain the jujube extract;

Abstract

The invention discloses a jujube flavor base, and a preparation method and application thereof. The preparation method for the flavor base comprises the following steps of: 1) performing pre-treatment on jujubes to obtain jujube particles; 2) adding ethanol and performing ultrasonic treatment to obtain jujube extract liquid; 3) performing rotary evaporation and concentration to obtain jujube extract; and 4) performing molecular distillation, separation and purification to obtain a light-component substance, an intermediate-component substance and a heavy-component substance, and performing extraction, overnight standing, filtration and filtrate concentration on the intermediate-component substance to obtain the jujube flavor base. The jujube flavor base of the invention can be used for preparing natural perfume materials for cigarettes and foods, also can be directly used as the natural perfume material, is prepared from the jujubes serving as the raw material, not only has the advantages of transparency, colorlessness, high liquidity and sweet perfume, also has the nutritional and healthcare effects of the jujubes, can be added into the cigarettes to effectively reduce miscellaneous odors in tobacco leaves, improve suction flavor and remaining taste, improve the natural fragrance of the tobacco leaves, comfort throats and treat pharyngitis, and also can be added into the foods to achieve the effects of increasing the flavor and making pure the flavor.
