Method for treating tobacco stem

Abstract

The invention relates to the field of tobacco, and more particularly relates to a method for treating tobacco stem, comprising the steps of: soaking the tobacco stem into the mixed solution of NH3.H2O and H2O2; filtering and washing filter residue; and roasting the washed filter residue. The invention also provides the best technical condition for the treatment of the tobacco stem: the tobacco stem is soaked into the mixed solution of 1.5% of NH3.H2O and 1.0% of H2O2 for 1h at 60 DEG C; and the ratio between liquid and material is 1:10. Compared with the untreated tobacco stem, the treated tobacco stem respectively reduces the content of cell wall material, lignin and total nitrogen by 12.71%, 2.14% and 1.24%; the filling quantity is increased, and impurity gas is reduced by sensory smoking; therefore, the method not only can increase the filling quantity of the tobacco stem, but also obviously reduces the content of lingo-cellulose the smell of lignin of the tobacco stem and improves the using value thereof, thus having industrial application prospect.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a method for processing shredded tobacco stems. Background technique [0002] Tobacco stems are a by-product of the tobacco industry. my country's tobacco industry generally adds cut tobacco stems to cigarette formula after swelling. However, the main component of cut tobacco stems is cell wall substances, accounting for more than 40%, including cellulose, hemicellulose, pectin and lignin. Thermal cracking of such substances will produce more low-level aldehydes, catechols, alkyl catechols, and methanol, etc., which will seriously affect the smoking quality of cigarettes, resulting in that the blending ratio of expanded cut stems in cigarette formulas is generally not high. However, a large number of tobacco stems are still discarded every year, resulting in waste of natural resources and environmental pollution. Therefore, it is of great significance to improve the availability of cut t...

Chinese Patent No. 1694628A discloses "Methods for Reducing Nitrogen-Containing Compounds and Lignin in Tobacco" which provides the process of using sodium hydroxide to treat tobacco leaves and tobacco fiber raw materials to produce reconstituted tobacco leaves. It is necessary to extract and separate the tobacco fiber raw materials first, and then Alkali oxygen treatment is carried out on the fiber part, and then separated, the process is more complicated

Sodium hydroxide is used to treat tobacco raw materials in the above alkali treatment process, which is easy to cause burning sensation
