Tobacco wrap paper aqueous dip-coating containing tea extract

Abstract

The invention provides a tobacco wrap paper aqueous dip-coating containing tea extract, which is prepared by using the following technical scheme of: (1) immersing pulverized black tea in boiling water for 0.5-10 h, filtering, taking filter liquid a, and concentrating the filter liquid a until the viscosity measured by using a coating 4 viscosity cup is 30-40 s; (2) in another container, firstly heating 100 parts of water to 80-100 DEG C and then mixing 18 parts of carboxymethylcellulose, 8-12 parts of cassava starch, 8-12 parts of guar gum with water and stirring to form a cross-linking mixed liquid b; and (3) stirring and mixing the products of steps (1) and (2) in the ratio of 1:(0.8-1.5) to obtain the aqueous dip-coating for wrap paper. The aqueous dip-coating for wrap paper can be well adhered to the wrap paper to reduce harmful substances in cigarette smoke; water is used as a solvent, the problem of residual volatile organic solvent after coating does not occur, and the invention has the advantages of energy saving, safety, no pollution and safer smoking.
