Description
Technical Field
The invention relates to the field of paper-making reconstituted tobacco, in particular to a method for improving the quality of paper-making reconstituted tobacco products by adopting tobacco raw materials as Maillard reactant carriers.
Background
The reconstituted tobacco is a sheet or filiform regenerated product prepared from waste tobacco materials such as tobacco powder, tobacco stems, tobacco shreds and the like in the cigarette making process as raw materials and used as cigarette filler. The reconstituted tobacco originated in the 50 th of the 20 th century, and the development of the reconstituted tobacco goes through 3 stages of a rolling method, a thick pulp method and a paper making method. Compared with the tobacco leaves reproduced by the roller pressing method and the thick paste method which are produced at present, the tobacco leaves reproduced by the paper-making method have unique advantages, including small density and high filling value; the mechanical processing resistance is good, and the filament forming rate is high; the combustion speed is high, and the tar release amount is low; good product plasticity and the like. At present, the processes adopted by various production enterprises are slightly different, and basically, a typical two-step method is slightly improved, stems and powder are extracted by water, the extracted tobacco powder and the tobacco stems are mixed and pulped, the pulp is sent to a paper machine for making and forming, two kinds of extraction liquid are prepared, mixed and coated on a sheet base after being treated by means of concentration and the like. The main procedures comprise raw material pretreatment, extraction, concentration, pulping, papermaking, coating, post-treatment and the like.
Although the proper amount of reconstituted tobacco is added into the cigarette, the raw materials of the tobacco leaves can be saved to the maximum extent, and the cost of the cigarette is effectively reduced; on the other hand, the physical properties and chemical components of the cigarette can be adjusted and improved to a certain extent according to the will or requirements of people, thereby being beneficial to improving the internal quality of the cigarette. However, compared with the traditional cut tobacco, the taste still has certain problems, the most obvious expression is that the wood gas is obvious, the irritation is difficult to cover, and therefore, the adding proportion is not high generally. Compared with the paper-making process and quality at home and abroad (tobacco science and technology, 2002), Chenzhuanggang and the like find that the imported sheets have lighter wood gas, certain tobacco original fragrance, smaller irritation and slightly paper flavor, and are relatively poor in domestic production; the content of important aroma components in the imported slices is obviously higher than that of the domestic slices. The results of the research on the release amount of main harmful substances in the smoke of the domestic and international paper-making tobacco sheets and the evaluation on the harmfulness of the smoke (modern scientific instruments 2010) show that the domestic paper-making tobacco sheets have a high CO/tar ratio and relatively low release amounts of phenol, ammonia and NNK, and the imported products show that the release amounts of benzo [ a ] pyrene and CO are low. It can be said that the domestic reconstituted tobacco leaves are not much different from foreign tobacco leaves in the tar and harm reducing technology, but have a certain difference from foreign tobacco leaves in the internal smoking quality.
The Maillard reaction has various species and different fragrance, and is widely applied to tobacco products as a flavoring agent. Usually, it can be obtained by selecting an appropriate reaction substrate, and controlling the reaction conditions, reaction time and reaction environment. The tar content is not obviously increased after the reactants are added, and adverse effects on the taste and other qualities are not brought. The tobacco powder as the leftover material of common cigarette enterprises has the characteristic of more sufficient aroma compared with tobacco stems, and the morphological particles can be ground into powder, so the tobacco powder is a good tobacco natural aroma substance carrier. Based on the characteristics, how to improve the use efficiency of the tobacco powder so as to improve the sensory quality of the reconstituted tobacco is very important. Therefore, the invention firstly considers that the tobacco raw material is ground into powder, then the tobacco powder and the reaction raw materials such as amino acid, sugar and the like are subjected to Maillard reaction, and finally the tobacco powder suspension loaded with Maillard reaction products is coated on the reconstituted tobacco substrate. The method for improving the quality of the paper-making reconstituted tobacco products by adopting the tobacco raw materials as the Maillard reactant carrier provides reference for domestic research and development of reconstituted tobacco and improvement of sensory quality.
Disclosure of Invention

the mesh number of the screen is 200 meshes and 400 meshes;
the tobacco powder is powder which passes through a 200-mesh screen and does not pass through a 400-mesh screen, the particle size distribution range is 200-400 meshes, the particle size is too large, the tobacco powder is not uniform in coating, and the smoking taste is influenced; the particle size is too small, and the particles are easy to permeate the substrate and cause loss during coating.
(2) Taking 1-10 parts by weight of amino acid, 10 parts by weight of aldose and 5-40 parts by weight of tobacco powder obtained in the step (1), dissolving propylene glycol and water in a weight part ratio of 1: 1-10 to obtain a solution, adjusting the pH value to 7-8, pouring the solution into a Maillard reaction bottle, carrying out Maillard reaction at 60-130 ℃ for 6-10 hours, and standing for later use;
(3) adding the Maillard reactant in the step (2) into a reconstituted tobacco coating liquid; the weight proportion of the added Maillard reactants is 5-20%;
(4) and (4) coating the coating liquid in the step (3) on a reconstituted tobacco substrate, drying by an oven, perfuming by a drying cylinder, and finally slicing to prepare a reconstituted tobacco finished product.
Preferably, the tobacco raw material is ground into powder by a grinding machine, and the powder is completely sieved by a 200-mesh sieve, and the particle size distribution is 200-400 meshes.
Further preferably, the amino acid is at least one selected from lysine, phenylalanine, cysteine, valine and glycine; the aldose is fructose and/or glucose.
In some embodiments of the present invention, the reconstituted tobacco coating liquid is prepared by the following steps: (a) respectively adding water into the tobacco raw materials for extraction; the tobacco raw material is at least one of tobacco stems, tobacco powder, broken tobacco leaves and tobacco ash; (b) respectively carrying out solid-liquid separation on the extracted slurry in the step (a) through a double-screw pulp extruder, a 600 high-concentration disc mill and a single-screw squeezer, feeding the solid-phase slurry into a 750 high-concentration disc mill, feeding the solid-phase slurry into a slurry tank, and finally carrying out pulp making through a pulp flowing box to obtain a reconstituted tobacco substrate; c) and (c) removing impurities and concentrating the collected liquid phase extract after extraction in the step (a) and carrying out alcoholization feeding to prepare the reconstituted tobacco coating liquid.
Compared with the traditional coating liquid, the coating liquid prepared by adding a certain mesh of tobacco powder in the Maillard reaction has the most intuitive effect of improving the smoking taste of the reconstituted tobacco. Especially when the ratio of the tobacco powder to the Maillard reactant is the above-mentioned preferred addition amount, the sensory quality of the reconstituted tobacco is greatly improved.
The method has simple treatment process, can well meet the requirements of the reconstituted tobacco production process, can directly carry out amplification batch production, and has good industrial application prospect.
