Abstract

The invention provides a method for preparing fermentation malt extract for cigarettes, belongs to the technical field of tobaccos, and relates a method for preparing perfume. The method comprises the following steps of: 1) preparing malt extract by preprocessing malt, and preparing a culture medium; 2) sterilizing the culture medium; 3) inoculating, namely inoculating saccharomyces cerevisiae into the culture medium; 4) fermenting; and 5) separating to obtain the fermentation malt extract for the cigarettes. In the method, the fermentation malt extract for the cigarettes is produced by utilizing the saccharomyces cerevisiae, so the fermentation malt extract has the faint scent of the malt and pleasant sweet and mellow fragrance; and by adding the fermentation malt extract into the cigarettes, the faint scent and soft smoke can be increased, and the irritation of the cigarettes is reduced. In the method, by using the microbial fermentation technology, a new path of producing natural perfume for the cigarettes economically, efficiently and directionally is opened up, the novel perfume for the cigarettes which cannot be produced by the conventional production method for the perfume is developed, and a new variety of the perfume for the cigarettes is developed.

Description

technical field [0001] The invention relates to a method for preparing tobacco spices, in particular to a method for preparing fermented tobacco malt extract. 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 one of the effective means to improve the product style and improve the quality of cigarette aroma. It can provide consumers with some aroma and Cigarette products with satisfying taste. At present, most of the tobacco flavors added to tobacco in my country are prepared by traditional methods, that is, mixed with natural extract monomers and synthetic monomers. The aroma is monotonous, the improvement of tobacco is insufficient, and the effect of improving the smoking quality of cigarettes is not obvious. [0003] Malt is obtained from the mature fruit of the gramineous plant barley (Hordeum vulgare L.) after germination and drying. It is rich in sug...
