example 1

[0012] The first step is to add 1 kg of chopped dry mulberry leaves to the extraction tank with a condensation cooling device, add 6 kg of water, fully soak the mulberry leaves and water, check the smoothness of the condensation cooling water and the pipeline, heat, Boiling (adding water in the process), condensing the steam to collect 6 kg of volatile oil and water;

[0013] The second step is to pump the volatile oil and water to the reverse osmosis membrane device to remove impurities and pre-concentrate;

[0014] The third step is to input the pretreated volatile oil and water into the chromatographic column for adsorption and separation in the chromatographic column; after the adsorption is completed, 3 kg of 65% ethanol is used for elution of the chromatographic column, and the eluent is collected;

[0015] The fourth step is to concentrate the eluent in a vacuum rotary evaporator, the concentration temperature is 70°C, the vacuum degree is -0.09Mpa, the eluate is concen...

[0019] The first step, in the extraction tank with condensation cooling device, add 3 kilograms of chopped dry mulberry leaves, add 20 kilograms of water, fully soak the mulberry leaves and water, heat, boil (add water in the process), Condensate steam to collect 25 kg of volatile oil and water;

[0020] The second step is to pump the volatile oil and water to the reverse osmosis membrane device to remove impurities and pre-concentrate;

[0021] The third step is to input the pretreated volatile oil and water into the chromatographic column for adsorption and separation in the chromatographic column; after the adsorption is completed, 3 kg of 65% ethanol is used for elution of the chromatographic column, and the eluent is collected;

[0022] The fourth step is to concentrate the eluate with a vacuum rotary evaporator, the concentration temperature is 70°C, and the vacuum degree is -0.095Mpa, and the eluate is concentrated to 200 grams, and sealed for storage.

Abstract

A preparation method of a mulberry leaf volatile oil and application thereof to cigarette perfuming are disclosed. The invention provides the preparation method of the mulberry leaf volatile oil and application thereof. According to the invention, the mulberry leaf volatile oil is obtained by the following steps: condensing and collecting volatile oil-containing water by a water distillation method, pre-treating with a reverse osmosis membrane to remove impurities, and adsorbing with an adsorption chromatographic column, eluting and concentrating. The mulberry leaf volatile oil provided by the invention is added to tobacco shreds, so as to make the tobacco aroma full and rich and modify the tobaccos to make the smoke gentle and fine; and the mulberry leaf volatile oil has obvious effects of masking odor and improving aftertaste comfort. The mulberry leaf volatile oil has good solubility properties, is applied to tobacco flavoring, has good effects, and serves as a novel and important natural flavor for tobacco flavoring.

Description

technical field [0001] The invention belongs to the field of preparation method and application of spices for tobacco, and in particular relates to the separation and extraction of mulberry leaf volatile oil by means of water distillation and adsorption chromatography and its application in cigarettes. Background technique [0002] Mulberry leaves are the dry leaves of the Moraceae plant Mulberry, which has high economic value, nutritional value, and medicinal value. Mulberry trees are planted in most parts of my country, especially in Jiangsu and Zhejiang provinces, where there has been a long history of planting mulberry and raising silkworms. my country has several million mu of mulberry gardens and is the largest mulberry planting country in the world. Mulberry leaves contain a variety of active ingredients, mainly flavonoids, alkaloids and polysaccharides, and other steroids, volatile oils, amino acids, vitamins and trace elements. Among them, flavonoids, alkaloids, p...
