Processing technology for lowering pectin content in cut stem

Abstract

The invention provides a processing technology for lowering pectin content in a cut stem, which comprises the following steps of: A) sieving and peeling: cutting a thick stem into even stem sections of 8-10mm, sieving according to the thickness, enabling the thick stem section of which a diameter is less than 2.38mm to directly enter the next working procedure, peeling and polishing the thick stem of which a diameter is more than or equal to 2.38mm, and removing the bast part of a tobacco stem by mechanical force; B) chemical stem cleaning and dipping: after the tobacco stem is cleaned with sodium metaphosphate contained citric acid solution of which the pH (potential of hydrogen) is 3.0+/-0.5, keeping the temperature of 50-60DEG C, and dipping for half hour; C) washing the stem with clean water; D) after feeding, pressing and cutting off the stem; and E) drying and storing the stem. Compared with the cut stem prepared by the traditional technology, the cut stem prepared with the method disclosed by the invention has the advantages that the physical behavior does not have obvious difference, but the aesthetic quality is obviously improved, the irritation is reduced, and the miscellaneous qi is reduced. After the cut stem is added into rolled cigarettes, the cigarette sucking comfort can be improved, and the tar content is lowered.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a processing technology for reducing pectin content in shredded stems. Background technique [0002] Tobacco belongs to the family Solanaceae. The thick and hard veins of the tobacco leaves are the tobacco stems, which account for 25-30% of the leaf weight. During production and processing, the tobacco stems generally need to be removed. Along with the huge cigarette output, hundreds of thousands of tons of tobacco stems are wasted every year, and a considerable part is prepared into shredded stems. Shredded stems can significantly improve the filling property of shredded tobacco, increase the fuel performance of cigarettes, and play a role in reducing the amount of tar and nicotine in cigarettes. It is an important raw material for cigarettes. [0003] The main chemical components of cut stems are basically the same as those of tobacco leaves, but due to the differen...

Problems solved by technology

At present, chemical and biological treatment methods are mainly used to improve the sensory quality of cut stems. For example, Chinese patent 200410079645.5 discloses a chemical stem washing method, which uses an aqueous solution containing ammonia (amine)-based chemicals to treat tobacco. Stems can improve the sensory quality of cut stems, but the efficiency of chemical treatment is low, and the quality of cut stems is limited; Chinese patent 200510104443.6 discloses a compound enzyme preparation and a process for using the compound enzyme preparation in the production of tobacco stems, using six enzymes Soak the tobacco stems in the formulated compound enzyme solution to improve the quality of cut stems; Chinese patent 201110118604.2 discloses a method for improving the quality of newly produced tobacco stems, which uses vacuum rehydration and artificial fermentation to improve the quality of tobacco stems; Chinese patent 201110199168.6 Disclosed is a Bacillus subtilis preparation used for treating tobacco stems. This microbial preparation can significantly improve the aroma, pleasantness and other qualities of cut stems, reduce miscellaneous gas and irritation, reduce smoke concentration and strength, and change aftertaste. To get comfortable, so as to further increase the blending amount of shredded stems in cigarettes, to achieve the purpose of reducing harm, reducing coke, and reducing cigarette production costs

Although the effect of the above-mentioned biological treatment process is good, it puts forward new requirements for the process, thus increasing the production cost
