Abstract

The invention discloses application of Dendrobium officinale polysaccharide to cigarettes. The amount of used Dendrobium officinale polysaccharide is 0.002-0.02 percent of weight of cut tobacco in the cigarettes. The preparation method of the Dendrobium officinale polysaccharide comprises the steps of: cleaning and drying Dendrobium officinale, crushing the dried Dendrobium officinale, extracting in water to obtain extract, cooling the extract, conducting centrifugal separation and vacuum suction filtration and vacuum-concentrating filtrate to obtain concentrated solution; and conducting ethanol precipitation to the concentrated solution, collecting sediment and freeze-drying the sediment to obtain the Dendrobium officinale polysaccharide. After the Dendrobium officinale polysaccharide is applied to the cigarettes, when the cigarettes are smoked, the smoke is mellow and full, the fineness and the softness are increased, the dry sensation is reduced and the quantity of aroma is increased.

Description

technical field [0001] The invention relates to the field of preparation and application of plant polysaccharides, in particular to the application of dendrobium officinale polysaccharides in cigarettes. Background technique [0002] Cigarette flavoring and moisturizing technology has always been the key to highlighting the characteristic aroma and personalized style of tobacco products. Moisturizing performance is an important factor affecting the aroma, flavor and smoking comfort of cigarettes. It is an important basis and basis for building the core technology of Chinese cigarettes. Assure. At present, the moisturizing performance of cigarettes is mainly improved by adding propylene glycol, glycerin and other substances as humectants in China, but the moisturizing effect is not obvious enough, and there are still problems such as rapid water dispersion, low smoke moisture, and high irritation. my country, such as Zhejiang Province, is rich in characteristic plant resourc...
