Description

The invention relates to a technology for processing tobacco waste.

A known method of producing reconstituted tobacco, comprising grinding the tobacco material, extracting it with water to separate the extract from the meal, suspending the meal in an aqueous liquid, using water itself or aqueous solutions of alcohols or sugars, exposing the suspension to release pectin by introducing into it acid salts of phosphoric acid or other pectin hydrolyzing reagent, suspension formation, introduction of tobacco extract and pectin cross-linking into it that as a water soluble salt of alkaline earth metals, preferably calcium, and drying (US 5339838, 1994).

The disadvantages of this method are the production of reconstituted tobacco with deliberately impaired organoleptic properties with respect to the starting material and unreasonably increased duration of the process.

The technical result of the invention is to improve the organoleptic properties of reconstituted tobacco and reduce the duration of the process.

This result is achieved by the fact that in the method for producing reconstituted tobacco, which involves grinding tobacco material, extracting it to separate the extract from the meal, suspending the meal in an aqueous liquid, exposing the slurry to release pectin, forming the slurry, introducing the tobacco extract and cross-linking pectin into it reagent and drying, according to the invention, grinding and extraction of tobacco material is carried out simultaneously by periodically depressurizing the ext ktsionnoy mixture below the pressure of saturated vapor at the temperature of the extractant the extraction, suspending seed meal is carried out in an aqueous solution of at least one acidic salt of a polybasic acid food, and as a crosslinking agent pectin used edible polyhydric alcohols.

The method is implemented as follows.

Tobacco material is prepared by removing impurities from it and mixed with one of the traditional extractants, for example, water, a water-alcohol solution or a non-polar liquefied gas. In the obtained extraction mixture, the pressure is periodically depressurized to a value below the saturated vapor pressure of the extractant used at the extraction temperature under traditional process parameters (RU 2255788, 2005). As you know, this leads to intensive destruction of the extracted raw materials and the release of its cellular contents into the extract (Zhuravskaya-Skalova D.V., Kvasenkov OI. New technology for the extraction of biological raw materials. // Collection of materials of the scientific-practical conference "Integration of fundamental and applied Research - the basis for the development of modern agricultural and food technologies "- Uglich: RAAS, 2007, p.111-112).

Since the destruction of the cellular structure of raw materials in this case occurs in the extractant, and not outside it, as in the closest analogue, the aromatic substances of the tobacco material cannot enter the environment, which eliminates their loss.

The implementation of the grinding of raw materials in the process of extraction is expected to reduce the duration of the process. In addition, grinding by shock waves in a liquid medium, in contrast to mechanical grinding, provides the most complete destruction of the cell membranes of tobacco material, which reduces the duration of the extraction itself.

After extraction is complete, the phases are separated by any known methods.

The resulting meal is suspended in an aqueous solution of one or more acidic salts of polybasic acids, which are food in accordance with SanPiN 2.3.2.1293-03. The concentration of the solution and the phase ratio are selected according to well-known recommendations for obtaining reconstituted tobacco with desired organoleptic properties (Puzdrova N.V. Theoretical substantiation and development of a system for evaluating and regulating the quality of smoking products. Abstract of thesis. Ph.D. - Krasnodar: KubGTU-OAO "Pogarsky Cigarette and Cigar Factory", 2004, p.15-16).

As you know, all aqueous solutions of acid salts of polybasic food acids hydrolyze protopectin (Donchenko L.V. Technology of pectin and pectin products. A manual for university students - M .: DeLi, 2000, pp. 32-40). Therefore, the creation of an additional effect on the suspension for the release of pectin substances in the proposed method is not required, which is expected to reduce the duration of the process. In addition, the raw material ground by the method described above has a more developed surface of the solid phase, which additionally accelerates the hydrolysis of protopectins and, accordingly, reduces the duration of this stage and the entire technological process. It should also be noted that the reduction of this stage allows to reduce the hydrolysis of pectin substances proper, while maintaining their high molecular weight and reducing the effect of deep hydrolysis products on the organoleptic properties of the target product.

Upon reaching the specified content of pectin substances in the suspension, determined by the required physical characteristics of the target product, the suspension is formed by known methods, for example, by applying to a breathable surface, injected into it by known methods, for example, by irrigation or spraying, a previously isolated extract and polyhydric alcohol classified as food in accordance with SanPiN 2.3.2.1293-03, and dried by known methods.

In the drying process, the ether crosslinking of the free carboxyl groups of pectin substances with polyhydric alcohol takes place with the formation of a skeleton system that ensures the preservation of the given product with the given shape.

The surface of the tobacco material, developed during hydraulic grinding, provides moisture removal faster than the closest analogue, which not only reduces the duration of the process, but also reduces the thermal effect on the target product, providing a reduction in the changes in the native substances of the tobacco material that affect its organoleptic properties. In addition, the replacement of the reagent at the stage of crosslinking of pectin substances from an alkaline earth metal salt with a polyhydric alcohol allows you to maintain a sense of the native taste and strength of the smoke of the target product,

Thus, the proposed method allows to obtain reconstituted tobacco with a shorter duration of the process and improve its organoleptic properties.
