preparation example Construction

[0021] A method for preparing an extract of broad bean flower for tobacco, characterized in that: the method for preparing the extract of broad bean flower for tobacco comprises the following steps:

[0022] A. Dry and pulverize the commercially available broad bean flower medicinal material and pass through a 60-120 mesh screen to obtain broad bean flower powder;

[0023] B. Extract broad bean flower powder and citric acid aqueous solution at a material-to-liquid ratio of 1:15 to 30 at a temperature of 80 to 100°C for 2 to 5 hours, and filter to remove the residue to obtain the broad bean flower primary extract;

[0024] C. Concentrate the initial extract of broad bean flower in step B to a solid content of 25-35%, add 95% ethanol solution, stir evenly, and set aside for 16-24 hours at 4°C for alcohol precipitation, and then use a ceramic membrane to filter, Concentrate the filtrate under reduced pressure until there is no ethanol smell to obtain the broad bean flower extract...

Embodiment 1

[0031] A. The broad bean flower medicinal material available in the market is dried and pulverized, and passed through a 100-mesh sieve to obtain broad bean flower powder.

[0032] B. Use citric acid aqueous solution with a pH of 5.0 as the extraction solvent, put broad bean flower powder and citric acid aqueous solution into an extraction container according to the ratio of solid to liquid 1:30, extract at a temperature of 90°C for 3 hours, and filter to remove the residue to obtain broad bean Flower initial extract.

[0033] C. Concentrate the initial extract of broad bean flower in step B to a solid content of 25%, add 95% ethanol so that the volume fraction of ethanol reaches 70% after the system is evenly mixed, and stand at 4°C for 16h to carry out alcohol precipitation. Then select a 0.5 μm ceramic membrane for filtration treatment, and concentrate the filtrate under reduced pressure until it has no ethanol smell, which is the broad bean flower extract of the present in...

Embodiment 2

[0035] A. Drying and pulverizing the commercially available broad bean flower medicinal material and passing through a 120-mesh sieve to obtain broad bean flower powder.

[0036] B. Use citric acid aqueous solution with a pH of 6.0 as the extraction solvent, put broad bean flower powder and citric acid aqueous solution into an extraction container according to the ratio of solid to liquid 1:25, extract at a temperature of 100°C for 3 hours, and filter to remove the residue to obtain broad bean Flower initial extract.

[0037] C. Concentrate the initial extract of broad bean flower in step B to a solid content of 35%, add 95% ethanol so that the volume fraction of ethanol reaches 80% after the system is evenly mixed, and stand at 4°C for 18h for alcohol precipitation. Then select a 0.4 μm ceramic membrane for filtration treatment, and concentrate the filtrate under reduced pressure until it has no ethanol smell, which is the broad bean flower extract of the present invention. ...

Abstract

The invention provides a preparation method of a broad bean flower extract liquid for tobacco, wherein the preparation method includes the steps of (1) drying and crushing commercial broad bean flower medicine, and sieving the medicine for later use; (2) with a citric acid water solution as an extraction solvent, performing extracting the broad bean flower powder under certain conditions, and filtering the extract to remove residues to obtain a broad bean flower primary extract liquid; and (3) performing alcohol-extraction, ceramic membrane filtration and pressure-reduced concentration to the broad bean flower primary extract liquid to obtain the broad bean flower extract liquid for tobacco. In the invention, the broad bean flower extract liquid is developed as a tobacco additive for the first time, so that the advantages of simple operation, economy and practicability, and convenience of production and conversion are achieved. The broad bean flower extract liquid, when being added to tobacco or filter tips, not only is an effect that the quality of the tobacco improved, but also the damage caused by smoking to human body can be reduced, thereby achieving potential damage reducing effect.

Description

technical field [0001] The invention relates to the technical field of cigarette essence and fragrance, in particular to a preparation method of broad bean flower extract for tobacco. Background technique [0002] With the development of low-tar cigarettes, the aroma of cigarette products is filtered and diluted, which will inevitably cause a large loss of aroma, which is difficult to meet the needs of consumers. At the same time, there are problems such as dry smoke, increased irritation, and reduced throat comfort. Affects the style and smoking quality of cigarettes. A challenging problem facing the tobacco industry is to reduce tar while maintaining sufficient flavor and comfortable smoking taste in cigarettes. At present, while many cigarette factories carefully deploy cigarette formulas, most of them adopt the method of adding various flavor enhancers and corrective agents to make up for the defects of cigarette fragrance and taste. Natural plant flavors have the adva...
