Example Embodiment

[0016] Example 1

[0017] Take 50 g of dried Astragalus root slices, add 500 mL of water, soak at room temperature for 1 h, heat and boil under normal pressure for 1 h, filter, and extract the filter residue twice with the same amount of water under the same conditions, and combine the three extracts , distilled and concentrated under normal pressure to obtain natural tobacco stem flavoring agent I.

Example Embodiment

[0018] Example 2

[0019] Take 50 g of dried Astragalus root slices, add 500 mL of 95% ethanol, soak for 1 h at room temperature, microwave for 0.5 h under reflux, filter, and extract the filter residue twice with the same amount of 95% ethanol under the same conditions, and combine the three extractions liquid, distilled and concentrated under normal pressure to obtain natural tobacco stem flavoring agent II.

Example Embodiment

[0020] Example 3

[0021] Take 50 g of dried slices of Astragalus root, add 500 mL of a mixture of water, ethanol and 1,2-propylene glycol, the mass fractions of water, ethanol and 1,2-propylene glycol are 50%, 45% and 5% respectively, soak at room temperature 1 h, ultrasonically oscillated for 1 h, filtered, and the filter residue was extracted twice with the same amount of water, ethanol and 1,2-propanediol mixture under the same conditions. Natural tobacco stem flavoring agent III.

[0022] Application comparison example

[0023] Take 5 g of natural tobacco stem flavoring agent I, II, and III, respectively, dilute with 10 g of 80% ethanol, spray the dilution evenly into 1 kg of expanded cut stems, seal the cut stems, and place them at room temperature for 6 hours. The proportions of 3%, 5%, and 8% (mass fraction) are uniformly mixed into the cut tobacco of the flue-cured type cigarette formulation. The control is the same kind of untreated expanded cut stems of the same k...

Abstract

The invention discloses application of an astragalus extract in stem strings or reproduced tobaccos. The application is characterized in that the astragalus extract is added into the stem strings or the reproduced tobaccos, so that the wood gas and the irritation of the stem strings or the reproduced tobaccos can be obviously reduced, the doping rate of the stem strings or the reproduced tobaccos in a medium-grade and high-grade cigarette formula is increased, and the smoke quality of cigarettes is not influenced; and the astragalus extract is prepared from astragalus by the process of solvent soaking, extraction and concentration. The application has the outstanding characteristics that new astragalus application is developed by the conventional solvent and the common extraction method; and a new natural stem flavoring agent is provided.

Description

technical field [0001] The invention relates to the field of tobacco additives, in particular to the application of an extract of Astragalus membranaceus in shredded stems or reconstituted tobacco leaves. The extract is applied to shredded tobacco stems or reconstituted tobacco leaves, which can significantly reduce the woody gas and Stimulation, increase the blending ratio of cut stems or reconstituted tobacco leaves in cigarette formula, without affecting the smoke quality of cigarettes. Background technique [0002] Tobacco stems, the main veins of tobacco leaves, account for about 25% to 30% of the weight of tobacco leaves. my country is a big tobacco producing country, producing hundreds of thousands of tons of tobacco stems every year. The main components of tobacco stems are cell wall substances, accounting for more than 40%, including cellulose, hemicellulose, pectin and lignin. When the tobacco stems are burned, the thermal cracking of these substances will produc...
