Problems solved by technology

[0005] At present, China has begun to study and use bio-fermentation to transform tobacco extracts. For example, CN101497844A reports a method for preparing tobacco spices by using microbial fermentation coffee. Mild and taste-improving effect, but the dominant bacteria used in this method has a wide variety, and the production conditions are difficult to control in the industrial production process, so it is not suitable for large-scale industrial production

Abstract

The invention discloses bacillus methylotrophicus, which is called bacillus methylotrophicus VJ4-1 and is collected with the collection number CCTCC NO:M 2012004. The invention provides a cimicifuga foetida tobacco extract for biologically transforming bacillus methylotrophicus and an application of a tobacco coffee extract to tobacco. Coffee can be used for producing a natural tobacco spice, i.e., a tobacco coffee extract by fermenting with a microorganism strain. A method disclosed by the invention has the advantages of simple process, wide raw material source, environmentally-friendly and harmless production process and good industrial use prospect; and the obtained natural spice extract can be directly applied to cigarette flavoring, has the advantages of capability of coordinating smoke, increase in light sweet flavor, fruit flavor, smoke fineness and flexibility, reduction in simulation, reduction in impure gas and improvement on smoking flavor, and can be mixed and blended with other tobacco essences and spices for use.

Description

technical field [0001] The invention relates to the technical field of spices for tobacco, in particular to a preparation method and application of bacillus methanolate and coffee extract for tobacco. Background technique [0002] In tobacco products, the aroma and taste of tobacco are very important. Flavoring and ingredients are the key links in the cigarette process and one of the effective means to improve the product style and improve the quality of cigarette aroma. At present, flavors for tobacco can be divided into chemically synthesized flavors and natural flavors, both of which have their own limitations. In recent years, natural plant flavors have become the focus and focus of research and development because of their natural harmlessness and easy availability of raw materials. The development of plant-extracted spices has limitations due to the limited available plant resources. It is a good idea to apply microbial fermentation engineering to the biosynthesis of ...
