Cigarette filter rod capable of reducing content of volatile carbonyl compounds in cigarette smoke and preparation method of cigarette filter rod

The invention discloses a cigarette filter rod capable of reducing the content of volatile carbonyl compounds in cigarette smoke and a preparation method of the cigarette filter rod. The cigarette filter rod is characterized in that mesoporous alumina particles capable of obviously reducing the content of the volatile carbonyl compounds in the cigarette smoke are added in a common cellulore filter rod to form the binary or ternary compound cellulore filter rod. The grain size of mesoporous alumina is 20-60 meshes, the average pore size of the mesoporous alumina is 10nm to 30nm, the BET surface area of the mesoporous alumina is 100-300 m<2> / g, and the crystal form of the mesoporous alumina is gamma-type alumina. The additive amount of the mesoporous alumina in the binary compound filter rod of each piece of cigarette is 10-40 mg / piece, and the additive amount of the mesoporous alumina in the ternary compound filter rod of each piece of cigarette is 70-120 mg / piece. Because of a specific acid environment of the smoke and molecular structure features of the carbonyl compounds, the mesoporous alumina can perform preferential adsorption on the volatile carbonyl compounds in the cigarette smoke by virtue of an electrostatic adsorption function and a nano-pore confinement effect, thereby achieving the purpose of alleviating the harm of the cigarette.

Laminaria japonica polysaccharide, its preparation method and application

The invention discloses a laminaria japonica polysaccharide, which is prepared by a method in the steps of: adding water into crushed laminaria japonica, adjusting the pH value to 1-4, conducting extraction for 2-5h at a temperature of 100-120DEG C; carrying out filtration so as to obtain an extracting solution, the pH value of which is adjusted to 6.3-7.0 by potassium-containing alkali, concentrating the extracting solution to a concentrated solution with solid content of 35-48%; adding ethanol into the concentrated solution and mixing them well, then leaving the solution to stand at a temperature of 4DEG C for 4-12h, and performing filtration so as to obtain a polysaccharide precipitate; implementing freeze drying, thus obtaining the laminaria japonica polysaccharide. The laminaria japonica polysaccharide, accounting for 0.01-1.0% of cut tobacco by mass, can be prepared into a solution. And the laminaria japonica polysaccharide solution can be added into cut tobacco or a filter tip through sprinkling so as to obviously enhance cigarette smoking quality, and reduce stimulation on a nasal cavity and throat. Accordingly, the laminaria japonica polysaccharide enables fine and smoothsmoke, soft mouthfeel, maintained aroma, and no side effect. The laminaria japonica polysaccharide provided in the invention has the advantages of no fishy smell, high extraction rate, easy acquisition, low cost and good oxidation resistance.

Wintergreen extraction method, cigarette comprising same and preparation method thereof

The invention discloses a wintergreen extraction method, a cigarette comprising same and a preparation method thereof, solving the technical problem of increasing cigarette aroma. The wintergreen extraction method comprises: refluxing and extracting, filtering and concentrating. In the cigarette comprising the wintergreen extractive, wintergreen extractive accounting for 0.001-20% of tobacco shred mass is added in the tobacco shred of the cigarette. The preparation method of the cigarette comprising the wintergreen comprises: dissolving wintergreen extractive by ethanol; evenly spraying onto the tobacco shred; naturally airing; and preparing into the cigarette by the common cigarette technology. Compared with the prior art, the invention contains the wintergreen extractive in the tobacco shred; in the smoking process, wintergreen extractive can enter the human body along with main smoke flow and is adsorbed by the human body through blood circulation so as to perform the functions of stimulating heart, lowering blood pressure, expanding blood vessels, improving immunity, resisting aging, strengthening, resisting fatigue, resisting pregnancy, performing antibiosis and the like; thecigarette has faint scent, full and pure smoke, has after sweetness and no offensive taste and can improve the smoking quality of cigarettes.
