Problems solved by technology

However, Burley tobacco extract has a typical aroma of Burley tobacco, which is generally used in mixed cigarettes and is not suitable for flue-cured tobacco.
[0003] As consumers pay more attention to smoking and health issues, low-tar cigarettes have become an inevitable trend in the development of cigarettes. While the amount of tar is reduced, the aroma and texture of low-tar cigarettes become weaker, the aroma of cigarettes becomes smaller, and the sense of satisfaction is greatly reduced. , which has a large gap with the long-term demand of consumers

Embodiment 1

[0015] A preparation method of burley tobacco extract, comprising the following steps:

[0016] (1) Take Burley tobacco, add water at a weight ratio of 1:12, and extract volatile oil by steam distillation to obtain Burley tobacco volatile oil A.

[0017] (2) After extracting the volatile oil, filter, filtrate B for later use, add water to the filter residue at a weight ratio of 1:10 for reflux extraction, reflux for 2.0 hours, filter while hot, and filtrate C for later use, and the filter residue can be directly used in the production of reconstituted tobacco leaves by the papermaking process.

[0018] (3) Filtrates B and C are combined and concentrated at 42°C to a density of 1.202g / cm 3 , to obtain Burley tobacco extract D.

[0019] (4) After adding 3.0 times the weight of ethanol with a mass fraction of 95% to the Burley tobacco extract D, settling and filtering, the filtrate was concentrated under reduced pressure to a density of 0.926 g / cm 3 , to obtain Burley tobacco c...

Embodiment 2

[0022] Weigh burley tobacco extract and add 0.06% to the low-tar cigarette leaf group formula (6mg / cigarette) with a price of 10 yuan, adjust the moisture content of shredded tobacco to about 12.5%, roll it into cigarettes, and put it in at a temperature of 22°C±1 , The relative humidity is 60% ± 2% in a constant temperature and humidity box for more than 48 hours to balance as sample 1 of the present invention, please evaluate the suction group to evaluate the suction. Under the same conditions, the same shredded tobacco was sprayed with the same amount of distilled water, and rolled into cigarettes as sample 2 of the blank control. Please refer to Table 1 below for the evaluation results.

Abstract

The invention relates to a preparation method of a burley tobacco extract. The preparation method comprises the following steps of adding water into burley tobacco according to the weight ratio of 1:12, and obtaining volatile oil A by adopting a water vapor distillation method; extracting and filtering the volatile oil, obtaining filter liquor B for standby, adding water into filter residues according to the weight ratio of 1:10 to backflow and extract for 2.0+ / -0.1h, filtering while hot, and obtaining filter liquor C for standby, wherein the filter residues can be directly applied in paper-making process reconstituted tobacco production; merging the filter liquor B and C, concentrating to the density of 1.200+ / -0.006g / cm<3> at the temperature of 30-45 DEG C, and obtaining the burley tobacco extract D; adding ethyl alcohol with the mass fraction of 95 percent into the burley tobacco extract D, then settling, filtering, vacuum concentrating the filter liquor to the density of 0.930+ / -0.006g / cm<3>, and obtaining a burley tobacco concentrate E, wherein the weight of the ethyl alcohol is threes times that of the burley tobacco extract D; adding the burley tobacco volatile oil A into the burley tobacco concentrate E, and uniformly mixing to obtain the burley tobacco extract. The burley tobacco extract prepared by the invention has more obvious effects in stimulation reduction, aroma enhancement, smoke smoothness, smoke concentration increase and the like, the residual taste of cigarettes can be improved, and the low-tar cigarette sensory quality can be obviously improved.

Description

technical field [0001] The invention belongs to the technical field of preparation and application of tobacco spices, and specifically refers to a preparation method of burley tobacco essence extract. Background technique [0002] Burley tobacco, safflower species. Mainly used as a raw material for blended cigarettes, it can also be used in cigars, pipe tobacco and chewing tobacco. Burley tobacco has higher moisture content, thin and light leaves, loose but not rough tissue structure, strong elasticity, high filling value, good flavor absorption performance, higher nicotine and total nitrogen content than flue-cured tobacco, stronger smoke, and lower sugar content , has a strong absorption capacity. The main cultivated varieties in my country include Eyan series and Dabai series. The burley tobacco extract prepared from burley tobacco belongs to the aroma of burley tobacco, which can effectively supplement the aroma of tobacco, correct the taste and taste of tobacco, and ...
