Embodiment 1

[0013] Accurately weigh 0.6 kg of dried spirit herb, chop it and soak it in 4 kg of water for 12 hours. Then it was placed in a steam distillation device, extracted by steam distillation for 6 hours, and the oil phase part in the distillate was collected to obtain 2.0 g of the volatile oil product of Herba Lingensis. Re-distill the remaining distillate after distillation and collect the distillate. Add 0.05 kg of sodium chloride in the distillate, then extract with an organic solvent with a weight ratio of ether: dichloromethane=60: 40, and the extract is concentrated under reduced pressure at 50 ° C in a water bath to obtain 4.2 grams of reddish-brown oil. Ling vanilla water-soluble volatile oil product.

[0014] Spray the extracted water-soluble volatile oil and volatile oil of the herb linguine according to the ratio of 0.015% of the weight of the shredded tobacco on the sample shredded tobacco according to the conventional flavoring process, and roll it into a cigarette s...

Embodiment 2

[0016] Accurately weigh 4 kg of dried spirit herbs, chop them and soak them in 20 kg of water for 20 hours. Then place it in a steam distillation device, adopt the steam distillation method to extract for 12 hours, collect the oil phase part in the distillate, and obtain 13 grams of volatile oil product of Herba Lingensis. Re-distill the remaining distillate after distillation and collect the distillate. 2 kg of sodium chloride was added to the distillate, and then extracted with dichloromethane. The extract was concentrated under reduced pressure in a water bath at 50° C. to obtain 20.0 g of a reddish-brown oily substance, which is the water-soluble volatile oil product of Herba Esperifolia.

[0017] Spray the extracted water-soluble volatile oil and volatile oil of the herb linguine according to the ratio of 0.05% of the weight of the shredded tobacco on the sample shredded tobacco according to the conventional perfuming process, and roll it into a cigarette stick, and keep ...

Embodiment 3

[0019] Accurately weigh 1 kg of dried spirit herb, chop it and soak it in 8 kg of water for 24 hours. Then it was placed in a steam distillation device, and extracted by steam distillation for 6 hours, and the oil phase part in the distillate was collected to obtain 3.5 grams of volatile oil product of Herba Lingensis. Re-distill the remaining distillate after distillation and collect the distillate. 0.2 kg of potassium chloride was added to the distillate, and then extracted with chloroform, and the extract was concentrated under reduced pressure in a water bath at 70°C to obtain 6.0 g of a reddish-brown oily substance, which is the water-soluble volatile oil product of Herba Linguian.

[0020] Spray the extracted water-soluble volatile oil of Herbs lingering and Herbs lingering volatile oil in proportion to 0.02% of the weight of shredded tobacco, and spray them on the sample shredded tobacco according to the conventional flavoring process to make cigarettes, and keep them a...

Abstract

The invention discloses a method for extracting water-soluble volatile components from lysimachia foenumgraecum comprising the following steps: chopping dry lysimachia foenumgraecum and soaking for 2-36hours, extracting for 0. 5-12hours in a steam distillation device, receiving oil phase parts of a distillate to obtain the lysimachia foenumgraecum 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 50-80 DEG C in a water-bath and obtaining oil-like components which are lysimachia foenumgraecum volatile oil. The lysimachia foenumgraecum water-soluble volatile oil has 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 lysimachia foenumgraecum 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 flavorings for tobacco, in particular to a method capable of extracting water-soluble volatile oil from spirit herbs. Background technique [0002] Lingxiang (Lysimachia foenum-gracum Hance), also known as Linglingxiang, vanilla, and lavender, belongs to the family Primulaceae and is a perennial herb. It is distributed in deep mountain forests or valleys in Yunnan, Guangdong, Guangxi, Sichuan, Guizhou and other places in my country. Next to the damp place. In recent years, a large number of varieties have been introduced and cultivated in Guangxi and other places, and the cultivation area has continued to expand. Among them, the Lingxiang herb produced in Dayao Mountain, Guangxi is the most authentic, with a unique and long-lasting fragrance and high economic value. Ling vanilla is sweet, light, and flat in nature, and has the functions of promoting qi, reli...
