Problems solved by technology

[0003] Sun-cured tobacco is similar to flue-cured tobacco in terms of shape, chemical composition, smoke, and taste. Its characteristic smoke has the best compatibility with flue-cured tobacco aroma, which can effectively increase the aroma of low-tar cigarettes and make up for the lack of aftertaste of low-tar cigarettes. However, the direct application of untreated sun-yellow tobacco in low-tar cigarettes will lead to a decrease in the elegance of the cigarette aroma, insufficient sweetness, unpleasant taste, and problems such as smoke irritation and miscellaneous gas

Abstract

The invention discloses a yellow sun-cured tobacco which is prepared by the following steps of: (1) adding 10-16 times of 90-95 percent of alcohol into the threshed and aired yellow sun-cured tobacco, performing reflux extraction at the temperature of 85-95 DEG C for 2-3 hours, filtering after extraction, wherein the filtrate is subjected to vacuum concentration to form the concentrated solution with the density of 0.97-0.99g / cm<3>; (2) adding 8-12 times of 65-75 percent of alcohol into the filtered yellow sun-cured tobacco, performing reflux extraction at the temperature of 90-95 DEG C for 2.5-3.5 hours, and filtering after extraction; and (3) drying the filtered yellow sun-cured tobacco in the step (2) to the moisture content of 12-15 percent, spraying the concentrated liquid obtained in the step (1), adding the additive according to 0.6-1 percent of the weight of the yellow sun-cured tobacco, baking at the temperature of 40-60 DEG C for 20-40 minutes, and obtaining the yellow sun-cured tobacco. The interior quality of the yellow sun-cured tobacco is improved, the application ratio of the yellow sun-cured tobacco in the low tar cigarette is improved, and the interior quality of the low tar cigarette is improved.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a sun-cured tobacco and a preparation method thereof, and also relates to a low-tar cigarette containing the sun-cured tobacco. Background technique [0002] As consumers pay more attention to smoking and health issues, low-tar cigarettes that are less harmful to the human body have become an inevitable trend in the development of cigarettes. Facing the large-scale attack and subtle penetration of foreign cigarette brands, Chinese-style cigarettes need to participate in international competition. It is necessary to adapt to the existing "low-tar" game rules. Therefore, increasing the development of low-tar cigarettes is not only an inevitable requirement for the industry to achieve "cigarette level", but also a means for enterprises to grasp the future development trend of the cigarette market. An important opportunity for the structure and benefits of ci...
