Method for producing flavoring for tobacco using waste tobacco leaf as raw material

Abstract

The invention discloses a method for producing a spice for cigarettes by using waste tobacco as a raw material. The method comprises the following steps: adding 5 to 10 percent of amino acid by weight into 5 to 15 percent of the waste tobacco by weight generated during threshing and re-drying, then adding 60 to 95 percent of solvent by weight into the mixture, placing the mixture into a normal-pressure reaction kettle, stirring the mixture evenly, adjusting the pH to be between 8.0 and 9.5, and then making the mixture react for 3 to 4 hours at a constant temperature of between 90 and 105 DEG C under the conditions of stirring, heating and condensing reflux; and after the reaction is ended, quickly filtering the hot reaction product, and decompressing and condensing the filtrate to obtain a spice product for the cigarettes, wherein the solvent comprises water, propylene glycol and ethylene glycol, and the ratio of the propylene glycol to the ethylene glycol to the water is 1-6:1-6-1. The spice for the cigarettes has the characteristics of obvious flue-cured tobacco note, fresh fragrance and sweetness, fragrance and sweetness of paste, fragrance of licorice, roasting fragrance, acid fragrance, and the like. When the spice is added into a tobacco product, the spice can enhance and enrich cigarette fragrance, fineness and softness, mellowness, smoke, and the like, and can promote internal quality of the cigarettes.

Description

technical field [0001] The invention relates to a preparation method of spices, in particular to a method for producing tobacco flavors by using waste tobacco leaves as raw materials. technical background [0002] With the reduction of tar in cigarettes, one of the challenges facing the tobacco industry today is to reduce tar while maintaining sufficient flavor in cigarettes. Since the Maillard reaction is an important reaction in the formation of tobacco characteristic aroma, the research on the application of Maillard reaction products in tobacco flavoring has attracted much attention at home and abroad. Preparation of tobacco flavor enhancer by Maillard reaction has become an important way to reduce tar while maintaining cigarette flavor. Onishi A.Nishi et al. conducted research on the application of Maillard reaction in tobacco flavoring earlier. At present, most of the tobacco flavors added to tobacco in our country are formulated with various natural flavors and synt...

Problems solved by technology

U.S. Patent (3,920,026) discloses a "tobacco flavoring agent", which mainly uses carbonyl compounds such as valine and dioxylacetone or pyruvic acid to prepare tobacco flavoring agents, but there are also aromas that are not realistic and natural. The improvement of tobacco quality is also limited. In addition, the variety is relatively single, and there is no room for choice; Chinese patent (CN 1 039776C) discloses "a method for preparing tobacco spices". Alkaline, enzymatic hydrolysis, centrifugal separation, carbonyl ammonia reaction and other steps to produce spices, it can be seen that the process route of this method is lengthy, complicated and time-consuming

Chinese patent (CN 1415717A) discloses "the method of producing tobacco spices with tobacco extract as raw material". High standard

[0003] In short, as the public has higher and higher requirements for reducing tar and harm of cigarettes, the production process and varieties of tobacco flavor raw materials that are suitable for reducing tar and reducing harm of cigarettes and improving the quality of cigarettes are not yet available. Relatively few, can choose the leeway also not big, have hindered the further development of tobacco industry to a certain extent, for this reason the industry department hopes that relevant scientific and technical personnel, provide a kind of preparation method of cheap and good quality simple and easy flavoring for tobacco, And can produce a wide variety of tobacco flavors to promote the technological progress of the tobacco industry
