Description
Method for Improving the Quality of Tobacco Stem by Combining Steam Explosion and Anaerobic Treatment Technology
Field of the Tnvention
The present invention relates to a method for improving the quality of tobacco stem by combining steam explosion and anaerobic treatment technology, which belongs to the field of tobacco processing.
Background to the Tnvention
Tobacco stern is an important component of tobacco leaves, which typically accounts for about 1⁄4 of the mass of a whole tobacco leaf. In the tobacco stem, the content of cellular wall substances. such as cellulose, hernicellulose, lignin. and pectin, is about 438% of the mass of dry matter. A relatively high content of cellulose, hemicellulose, lignin. and pectin makes the tobacco stem irritating strong source of irritant. It has a strong impure odor, can cause choking when inhaled and harsh to taste, and has a small quantity of aroma, which limits its percentage of use in a cigarette formulation.
Statement of Invention
The object of the present invention is to provide a method for improving the quality of tobacco stern by combining steam explosion and anaerobic treatment technology so as to improve the practical application value of tobacco stem in cigarette production and lower the cost of cigarette production.
The object of the present invention is attained by: a method for improving the quality of tobacco stem by combining steam explosion and anaerobic treatment technology, which combines steam explosion and anaerobic treatment technology to treat tobacco stem so as to effectively reduce the discomfort, such as its woody flavour, choking and coughing, caused by lignin and cellulose contents in the tobacco stem, and improve the quality of tobacco stem, said method comprising the following steps of: a) Using a steam explosion machine to perform steam explosion on the wetted tobacco stem; b) Placing the exploded tobacco stern into a sealed container, adding anaerobic microbes, and forming an anaerobic environment inside the container by vacuuming or introducing an inert gas for anaerobic treatment; c) Retrieving the tobacco stern from the anaerobic treatment container for rapid dehydrating treatment at low temperature, such that water content of the tobacco stem is controlled at 20 30%; d) Lastly, shredding the dewatered tobacco stern for use in cigarette production.
The above steam explosion method is: using a saturated steam as the working medium, and implementing thorough explosion on the tobacco stem by adjusting the pressure of the saturated steam and the duration of the pressure action.
The above anaerobic microbe is lactobacillus, The temperature of the above dehydrating treatment at low temperature of the exploded tobacco stem after anaerobic treatment is below 60°C.
The above steam explosion pressure is 0.8 MPa, and the steam pressure is kept constant for 20 seconds. In the above Step b, the anaerobic treatment is carried out in such a way: adding activated lactobadillus into the exploded tobacco stem through even spraying, then placing it into a sealed container, forming an anaerobic environment inside the container by introducing CO2 gas via an inlet pipe for 2 minutes to drive out the air inside the container thereby creating an anaerobic environment within the container, carrying out the anaerobic treatment away from light at room temperature, and the treatment lasts 7 days. In the above Step c, the tobacco stem is dried with a gas flow at 40°C.
The present invention has the following advantageous effects: in the case of steam explosion, high pressure steam permeates among large molecules of cellulose and lignin in structural tissues of the tobacco stern, and due to the rapid loss of pressure external to the tobacco stem, the highly pressurised steam inside the tissues is instantaneously released such that the tobacco stem is broken. As a result, the ligno-cellulose structure is separated and the tobacco stem structure becomes loose after the explosion, which is favorable for the permeation of and conversion by anaerobic microbes in the subsequent anaerobic treatment. At the same time, the high pressure and high temperature environment of steam explosion in the present invention can further effectively achieve the conversion of substances, such as cellulose, hemicellulose, and pectin, in the tobacco stem, and reduce the woody flavor, choking and coughing caused by lignin and cellulose in the tobacco stem. At the same time, the steam explosion can also increase the content of reducing sugar in the exploded tobacco stern. and improve the smoking quality of tobacco stem. The application of anaerobic treatment can further promote the conversion of cellulose and hemicellulose in the exploded tobacco stem, increase the content of small molecule organic acids and alcohols in the tobacco stern, and lessen the irritant aspect of nicotine. The combination of steam explosion and anaerobic treatment on tobacco stem can effectively improve the quality of tobacco stem, thcrease the amount of tobacco stem that can be added in the cigarette production. and is important for lowering the cost of cigarette production.
Detailed Description of the Preferred Embodiment(s) A method for improving the quality of tobacco stem by combining steam explosion and anaerobic treatment technology, which combines steam explosion and anaerobic u'eatment technology to treat tobacco stern so as to effectively reduce the discomfort, such as its woody flavor, choking and coughing, caused by the lignin and cellulose in the tobacco stem, and improve the quality of tobacco stem, said method comprising the following steps of: a) Using a steam explosion machine to perform steam explosion on the wetted tobacco stem; b) Placing the exploded tobacco stem into a sealed container, adding anaerobic microbes, and forming an anaerobic environment inside the container by vacuuming or introducing an inert gas for anaerobic treatment; c) Retrieving the tobacco stern from the anaerobic treatment container for rapid dehydrating treatment at low temperature, such that water content of the tobacco stem is controlled at around 20 30%; d) Lastly, shredding the dewatered tobacco stem for use in cigarette production.
The steam explosion method is: using a saturated steam as the working medium, and implementing thorough explosion on the tobacco stern by adjusting the pressure of the saturated steam and the duration of the pressure action. The anaerobic microbe is lactobacillus. After the anaerobic treatment, the exploded tobacco stem should be immediately dewatered at low temperature and the treatment temperature is below 60°C.
The steam explosion pressure is 0.8 MPa, and the steam pressure is kept constant for 20 seconds. In the above Step b. the anaerobic treatment is carried out in such a way: adding activated lactobacillus into the exploded tobacco stern through even spraying, then placing it into a sealed container, forming an anaerobic environment inside the container by introducing CO2 gas via an inlet pipe for 2 minutes to drive out the air inside the container thereby creating an anaerobic environment within the container, carrying out the anaerobic treatment away from light at room temperature, and the treatment lasts 7 days. In the above Step c, the tobacco stem is dried with a gas flow at 40°C.
The basic guarantee for the implementation of said method is to first perform steam explosion on the tobacco stem, and then subject the steam exploded tobacco stem to anaerobic treatment. As well as improving the quality of tobacco stem, steam explosion can make the structure of tobacco stem loose and facilitate the subsequent anaerobic treatment and process.
Moreover, the processing conditions of high pressure and high temperature thereof also sterilize the raw material prior to the anaerobic treatment of tobacco stem. Therefore, anaerobic treatment needs to be performed immediately after the steam explosion so as to reduce the degradation and conversion of the exploded tobacco stem by microbes in the air that could affect its quality. At the same time. direct sunlight should be avoided in the anaerobic treatment process.
Preparation example:
Take 5 kg of tobacco stem that has gone through regular processes, including refining and alcoholisation. use a steam explosion machine to perform explosion treatment on the tobacco stem, the explosion working medium is saturated steam, the explosion pressure is 0.8 MPa, and the pressure is kept constant for 20 seconds. After the steam explosion of the tobacco stem, immediately add activated lactobacillus into the exploded tobacco stem through even spraying, then p'ace it into two tO L g'ass Mariotte bottles (the air vent at the mouth of the Mariotte bottle is sealed with silicone or acrylic sealant. both the bottle mouth and lower opening of the Mariotte bottle are sealed with rubber plugs, glass tubes are installed on the rubber plugs, one end of the glass tube extends 1 cm into the bottle, the other end is connected with a latex tube, and the latex tube is equipped with a control clamp). In use, open up the latex tube at the mouth of the bottle by unclamping the clamp, introduce CO2 gas for 2 minutes through the glass tube at the lower opening of the bottle, and gradually drive out the air in the bottle. When the gas introduction is completed, first close the glass tube on the mbber plug at the mouth of the bottle and then close the glass tube at the inlet such that an anaerobic environment is formed in the glass bottle, perform anaerobic treatment at room temperature away from light, and the treatment duration is 7 days. Dry the above treated tobacco stem with a gas flow at 40°C, and then shred, carry out cigarette processing according to a cigarette formulation, and the amount of added stem shreds can be increased by 4 7%. The organoleptic evaluation of the smoking shows that when the amount of steam explosion and anaerobic treatment treated stem shreds is increased in the cigarette, the sensoiy quality of the cigarette does not have a noticeable difference from that of the original cigarette formulation.
The steam pressure as described herein is gauge pressure.
