Embodiment 1

[0012] Accurately weigh 0.5 kg of dried whole herb of centipede, chop it and soak it in 5 kg of water for 10 hours. Then place it in a steam distillation device, adopt steam distillation to extract for 6 hours, collect the oil phase part in the distillate, and obtain 1.0 g of water centipede volatile oil. Re-distill the remaining distillate after distillation and collect the distillate. Add 0.5 kg of sodium chloride to the distillate for salting out, then extract with ethyl acetate, concentrate the above extract under reduced pressure in a water bath at 70°C, and obtain 1.5 g of reddish-brown oily substance as water-soluble volatile components of centipede .

[0013] Spray the extracted water centipede volatile oil and water-soluble volatile components of the water centipede according to the ratio of 0.012% of the cut tobacco weight on the sample cut tobacco according to the conventional flavoring process, and roll it into a cigarette stick, and hold it at a constant temperat...

Embodiment 2

[0015] Accurately weigh 10 kilograms of dried whole herbal centipede, chop it and soak it in 40 kilograms of water for 20 hours. Place then in steam distillation device, adopt steam distillation method to extract 12 hours, collect the oil phase part in the distillate, obtain 25.3 grams of water centipede volatile oil. Re-distill the remaining distillate after distillation and collect the distillate. Add 2 kg of sodium chloride to the distillate for salting out, extract with petroleum ether (30-60), concentrate the above extract under reduced pressure in a water bath at 55°C, and obtain 40.8 g of reddish-brown oily substance that is water-soluble volatile components.

[0016] The extracted water centipede hair oil and the water-soluble volatile components of water centipede are respectively sprayed on the sample cut tobacco according to the routine flavoring process in the proportion of 0.05% of the cut tobacco weight, and rolled into cigarettes, and kept at a constant tempera...

Embodiment 3

[0018] Accurately weigh 1 kg of dried whole herb of centipede, chop it and soak it in 4 kg of water for 24 hours. Then place it in a steam distillation device, adopt steam distillation to extract for 6 hours, collect the oil phase part in the distillate, and obtain 2.1 grams of water centipede volatile oil. Re-distill the remaining raffinate after distillation and collect the distillate. Add 0.5 kg of potassium chloride to the distillate for salting out, then extract with ether, and concentrate the above-mentioned extract under reduced pressure in a water bath at 60°C to obtain 4.0 g of reddish-brown oily substance that is a water-soluble volatile component of centipede.

[0019] Spray the extracted water centipede volatile oil and water-soluble volatile components of water centipede according to the ratio of 0.05% of the cut tobacco weight on the sample cut tobacco according to the conventional flavoring process, and roll it into a cigarette stick, and keep it at a constant t...

Abstract

The invention discloses a method for extracting water-soluble volatile components from Kyllinga brevifolia comprising the following steps: chopping dry Kyllinga brevifolia and soaking for 4-36hours, extracting for 1-12hours in a steam distillation device, receiving oil phase parts of a distillate to obtain the Kyllinga brevifolia volatile oil; redistilling residual distillate after the distillation and receiving the distillate, extracting the distillate by organic solvent after the distillate salting out, vacuum concentrating the extract at a temperature of 50-70 DEG C in a water-bath and obtaining oil-like components which are Kyllinga brevifolia volatile components. The Kyllinga brevifolia water-soluble volatile components have finer and softer aroma and better application effect in tobacco flavoring comparing to the volatile oil extracted by conventional steam distillation method, moreover because the antioxidant ability of the Kyllinga brevifolia volatile components is greatly stronger than the volatile oil extracted by conventional steam distillation method, the harm of smoking to health can be reduced in the tobacco flavoring application, which accords with the long-run development trend of the tobacco industry.

Description

technical field [0001] The invention relates to a method for extracting water-soluble volatile components from natural tobacco spices, in particular to a method capable of extracting water-soluble volatile components from water centipedes. Background technique [0002] Volatile oil is an important raw material for blending tobacco flavors and is widely used in tobacco flavors. At present, the production of volatile oil adopts the traditional steam distillation process, and generally only the oil phase part of the distillate is collected as the product of volatile oil. The biggest disadvantage of this process is that the water-soluble volatile components in the raw materials are not easy to extract. The volatile components of plants can be divided into two categories, one is oxygen-free terpene compounds, which are insoluble in water, have no significant aroma, and are not the aromatic components of volatile oil. The other type is oxygenated terpenoids, which are usually no...
