The invention discloses a laminarin. The laminarin is extracted and obtained by the following method: smashing kelp and then adding water, and extracting for 2-5 hours at the temperature of 105-125 DEG C; filtering to obtain extract, and concentrating the extract so as to obtain a concentrated liquid in which the content of solid substances is 35-45%; adding ethanol in the concentrated liquid forevenly mixing, and then standing for 4-12 hours at the temperature of 0-4 DEG C, and filtering so as to obtain polysaccharide precipitate; and carrying out freeze drying to obtain the laminarin. The laminarin the mass of which is 0.01-1.0% of pipe tobaccos is prepared into a solution, and then the laminarin solution is added in the pipe tobaccos or a filter tip through a spraying mode, thereby effectively reducing the content of free radical in main steam smoke of cigarette and also improving the smoking quality of cigarette, wherein the content of the free radical is reduced by more than 18%. The laminarin has the functions of reducing stimulation effect on nasal cavity, throat and the like, leading smoke to be smooth, leading mouth feel to be soft and maintaining aroma, and has no any side effects. The laminarin has no fishy smell, high extraction efficiency and low cost, and is easy to obtain.

The present invention relates to a preparation method of popping beads for tea-baked cigarettes, comprising the following steps: step (1), preparing an oil bath reactant; step (2), extracting tea-baked fragrance; step (3), preparing tobacco Use popping beads. The invention can remove smoke irritating or miscellaneous substances such as macromolecular substances, and obtain pure roasted aroma substances. The compounding of tea roasted aroma substance and baicalin in the present invention can significantly reduce the content of free radicals in smoke, and the obtained popping beads for cigarettes can also improve the roasted aroma and smoking taste of cigarettes, and can effectively improve the flavor of cigarette products. The quality of roasting aroma, reducing the amount of miscellaneous gas, improving the comfort and coordination of cigarettes, can greatly improve the flavor and taste of rich cigarettes.

The invention discloses a porphyra polysaccharide which is prepared by the following method steps: smashing porphyra and extracting for 2-5 hours in water with pH value of 1-5 and temperature of 100-120 DEG C; filtering, regulating the pH value of extract to 6.3-6.7 with potassium-containing alkali, and concentrating the extract until the content of solid substances is 40-50%, so as to obtain a concentrated liquid; adding ethanol in the concentrated liquid for evenly mixing, and then standing for more than 8 hours at the temperature of 4 DEG C so as to obtain polysaccharide precipitate; and carrying out re-dissolution and freeze drying on the polysaccharide precipitate, so as to obtain the porphyra polysaccharide. The porphyra polysaccharide the mass of which is 0.01-1.0% of pipe tobaccosis prepared into a solution, and then the porphyra polysaccharide solution is added to the pipe tobaccos or a filter tip through a spraying mode, thereby effectively reducing the content of free radical in main stream smoke of cigarette and also improving the smoking quality of the cigarette. The porphyra polysaccharide has the functions of reducing stimulation effect on nasal cavity, throat and the like, leading smoke to be smooth, maintaining aroma and improving the quality of tobacco products, and has no any side effects. The porphyra polysaccharide has high extraction efficiency and low cost, is easy to obtain and can meet industrial application.
