Abstract

The invention discloses a Bacillus methylotrophicus strain VJ4-1 of which the preservation number is CCTCC No:M 2012004. The invention provides a tobacco angelica sinensis extract prepared by using microbe Bacillus methylotrophicus and conducting biotransformation and an application of the angelica sinensis extract in tobacco. According to the invention, by applying the fermented and purified tobacco angelica sinensis extract in cigarettes, the extract is in harmony with the smoke, increases the sweet aroma and the sweetness after taste, reduces the irritancy, reduces miscellaneous gases, strengthens the penetrability, makes the smoke soft and smooth, reduces the drying degree, make the aftertaste good, and improves the tasting; the method has the advantages of simple process, mild reaction conditions, low pollution, high concentration of the products, simple extraction steps, clean production, environmentally friendly product, safety and reliability, wide sources of main raw materials, extremely low cost, and nature, and has an industrial production prospect.

Description

technical field [0001] The invention relates to the technical field of spices for tobacco, in particular to a method for preparing Bacillus methanolate and angelica extract for tobacco. Background technique [0002] In tobacco products, the aroma and taste of tobacco are very important. Adding spices is a key link in the cigarette process, and it is also an effective means to improve the product style and improve the quality of cigarette aroma. Tobacco flavors can be divided into chemical synthetic flavors and natural flavors. In recent years, natural spices, especially Chinese herbal medicine extracts, have become the focus and hotspot of ingredient research and development because of their Chinese characteristics, natural harmlessness, and easy availability of raw materials. [0003] Angelica (Radix Angelicae Sinensis), also known as Qingui, Yungui, etc. At present, the medicinal material Angelica sinensis refers to the root of the Umbelliferae plant Angelica sinensis. ...
