Method for treating American burley tobacco

Abstract

The invention discloses a method for treating American burley tobacco, comprising the steps of: adding internal materials to burley tobacco leaves in twice in a loosening and moisturizing step and a charging step respectively, carrying out dry treatment on the tobacco leaves in a burley tobacco dryer, and adding external materials and then directly mixing with flue-cured tobacco and aromatic tobacco in a formulation of a product; wherein, in the loosening and moisturizing step, reducing sugar, humectant, Maillard reaction intermediate and plant extracting liquid are added to internal material liquid, the moisture content of the moisturized tobacco leaves is 24-28%, the tobacco leaves are stored in a storage tank for 2-4h and discharged, then liquorice paste liquid and cocoa powder liquid are added on line in the charging step, and after charging, the moisture content of the tobacco leaves is 32-38%. The method ensures that Maillard reaction can be fully carried out on a burley tobacco sheet, improves aromatic characteristics and aromatic amount of the treated burley tobacco and effectively reduces pungency and miscellaneous gas at the same time.

Description

Technical field: [0001] The invention relates to a method for treating American burley tobacco. Background technique: [0002] Burley tobacco belongs to Nicotiana (Nicotiana), a type of safflower tobacco (N.tabac-un). Because the stems and veins of Burley tobacco are milky white, it is more accurate to call it White Burley tobacco (White Burley tobacco). Burley). It originated in Ohio, USA. Compared with other types of tobacco leaves, Burley tobacco leaves are larger and thinner, with loose tissue, strong elasticity, high filling power, and good suction capacity, which can absorb a large amount of liquid added during processing. Burley tobacco has high total nitrogen and nicotine content, low sugar content, low tar release when burning, strong smoldering fire retention, and white ash. The leaves have a special aroma, and the Burley tobacco has a particularly good aroma retention performance after being processed with additives. Due to these characteristics, it is helpful ...

Problems solved by technology

However, this patent does not explain the basis for the selection of spices to be applied twice in the lining. It only elaborates the method from the proportion distribution of the amount of material added. Although it can solve the problem of uniform moisture content of Burley tobacco sheets and uniform absorption of material liquid to a certain extent However, since the first feed liquid contains additives such as cocoa and licorice that are not easily absorbed by Burley tobacco sheets, it will block the pores of the leaf cells during the full absorption process of the stored leaves, which is not conducive to the second feed liquid The full absorption of the second feed liquid will not only affect the addition amount of the secondary feed liquid and reduce the suction performance of Burley tobacco, but also easily cause the second feed liquid addition to be not uniform enough, which will reduce the treatment effect of the subsequent Burley tobacco roasting process on Burley tobacco sheets
