Extraction method of polysaccharides from morinda officinalis how and application thereof in cigarette

Abstract

The invention provides a method for extracting polysaccharides from morinda root and the application of the polysaccharides in cigarettes. The method for extracting the polysaccharides comprises the steps as follows: morinda root is dried, and pulverized into powder of 10 to 100 meshes; the morinda root powder is immersed and extracted by adding water at 50 to 100 DEG C; subsequently, the mixtureof the morinda root powder and water is filtered and the filtrate is concentrated; the concentrated filtrate is added to ethanol to ensure the ethanol to account for 80 percent in volume; the mixtureof the concentrated filtrate and the ethanol are allowed to be settled out and filtered, thus getting the raw polysaccharides; the raw polysaccharides are put in water for redissolution; a sevag reagent 0.1 to 1 time of the raw polysaccharide solution in volume is added, and is shaken and allowed to be separated into layers; the mixture of the thick sevag and protein on the lower layer is removed; the pH value is adjusted to 9 to 10 with ammonia; oxydol 30 percent of the solution in mass is added slowly until the solution is turned into straw yellow; after the solution is decolored, the solution is condensed before ethanol with the concentration from 95 to 100 percent is added, the volume percentage of the ethanol is kept to be 80 percent; the solution is allowed to be settled out for 24 to 48 hours, thus getting the polysaccharides from morinda root through filtration.

Description

technical field [0001] The present invention relates to the extraction of plant polysaccharide and its application, in particular to the extraction method of Morinda officinalis polysaccharide and its application in cigarettes. The application of this technology does not change the existing processing technology of cigarettes, can improve the sensory quality of cigarettes, and reduce the harmfulness of cigarettes. Background technique [0002] As the problems of smoking and health attract more and more attention, it is an inevitable development trend of cigarettes to improve the smoking safety of cigarettes, increase health care functions, and reduce harmful components in cigarette smoke. Therefore cigarette varieties such as ginseng cigarettes and peppermint cigarettes have appeared on the market, that is, materials with unique functions or tastes such as ginseng and peppermint have been added in shredded tobacco. [0003] Morinda officinalis is a famous and precious tradi...

Problems solved by technology

However, the influence of different process conditions, such as temperature, solid-liquid ratio, extraction time and concentration ratio on the yield of polysaccharides, has not been considered.

Hydrogen peroxide, as an oxidative decolorizing agent, has been reported for the extraction and purification of plant polysaccharides, but there is no relevant report for the extraction and purification of Morinda officinalis polysaccharides
