Definitions

  • the present invention relates to a process for the preparation of reconstituted tobacco, flavored by fermentation, and the flavored reconstituted tobacco obtained by this process and the tobacco mixtures comprising it.
  • the reconstitution consists in transforming this debris into a sheet which is then chopped and reincorporated in the tobacco tobacco mixtures or used as an envelope for cigars (undercoats and capes).
  • This sheet can be obtained by grinding, attrition or disintegration of the debris and then mixing with a binder and various additives (reinforcing fibers, fungicides, humectants, flavors, various fillers), spreading the paste obtained on an endless metal strip, drying , winding and, if necessary, splitting of the sheet in the form of strips.
  • various additives reinforcing fibers, fungicides, humectants, flavors, various fillers
  • FIG. 1 gives the conventional diagram.
  • tobacco debris from threshing or chopping the leaves is collected and after sieving, mixed with water, for example in a digester 1, which makes it possible to extract the water-soluble products.
  • the soluble products are then separated from the insoluble, for example, by passing the pulp obtained through a screw press 2.
  • the insoluble products are therefore dissociated from the soluble products in order to treat them separately.
  • the fibers pass, for example, through a refiner 3 before passing through a paper machine 4 to form a sheet of tobacco fibers or base sheet.
  • the products soluble in aqueous solution from the pressing that is to say the strong liquor, are concentrated, for example, in a vacuum evaporation device 5, before being reincorporated in the base sheet to form a reconstituted leaf.
  • the reconstituted sheet is then treated in a drying device 6.
  • This reconstituted tobacco leaf will then be cut into sheets similar to tobacco strips which are reintroduced into tobacco tobacco mixtures.
  • These sauces may include humectants, such as glycerin or propylene glycol, sugars, such as glucose or invert sugar, flavorings, such as cocoa, licorice or fruit extracts, or synthetic flavorings or additives.
  • humectants such as glycerin or propylene glycol
  • sugars such as glucose or invert sugar
  • flavorings such as cocoa, licorice or fruit extracts
  • synthetic flavorings or additives such as cocoa, licorice or fruit extracts.
  • the flavoring is carried out for example by spraying "sauces" before or after the drying of the tobacco.
  • these sauces or juices are added to the impregnation liquor.
  • the major drawback of these sauces or juices comes from the fact that substances foreign to tobacco, and therefore taste properties, are introduced into tobacco "notes" which are not identical to those of tobacco.
  • the present invention aims to also use fermentation to improve the aroma of tobacco but avoiding the aforementioned drawbacks.
  • the invention thus provides a process for the preparation of flavored reconstituted tobacco from tobacco particles in which these particles are mixed with water to obtain, on the one hand, an aqueous solution (called "strong liquor") containing the water-soluble products.
  • tobacco particles and, on the other hand, insoluble products, the strong liquor is separated from the insoluble products, the strong liquor is concentrated, sheets are made from said insoluble products and said concentrated strong liquor is incorporated into said leaves so to obtain, after drying, reconstituted tobacco leaves, characterized in that before concentration, said seed is sown strong lacquer with yeast and the yeast is removed after fermentation.
  • tobacco particles are called parenchyma debris, and / or fragments of ribs or ribs and / or tobacco dust produced during the various manipulations and treatments during the transformation of the natural tobacco leaf into a smoking product. .
  • the strong liquor can be subjected to other treatments to remove constituents deemed undesirable, but these other treatments which are not concerned by the present invention will not be described.
  • microorganisms have also been used to reduce the content of other components in tobacco, such as nicotine (FR-A-2 437 794, US-4 140 136, US-4151 848).
  • the method according to the invention makes it possible to flavor the sides, in particular the parts of the leaves which are usually without aroma relative to the parenchyma of the leaves and therefore to enhance these parts, and this without introducing notes foreign to the notes of tubac himself.
  • the function of the yeast with which the strong liquor is sown is, on the one hand, to compete with the undesirable contaminating natural flora, on the other hand, to use the assimilable substrates contained in the strong liquor, mainly reducing sugars, to produce components. flavorings.
  • the yeasts used preferably come from strains chosen from the genera Candida, Kluyveromyces or Saccharomyces, for example, from Candida Pseudotropicalis, Candida utilis, Kluyveromyces fragilis, Saccharomyces diastaticus, Saccharomyces cerevisiae, preferably Kluyveromyces fragilis and Saccharomyces cerevisiae, selected for their good flavoring of the strong liquor without nutrient supply, and their heat resistance, necessary during the process.
  • yeasts can come from cultures of strains in a synthetic medium or from the recycling of yeasts at the end of a previous fermentation.
  • the strong liquor, before sowing, should preferably have a refractometric index of between 1% and 15%, preferably between 4% and 12%, its initial sugar concentration should preferably be between 5 and 20 g / l.
  • the strong liquor in general, with a view to its flavoring, can be fermented without adding any external component, although these may be useful under certain particular conditions.
  • This strong liquor is seeded with yeast so that the seeded liquor has an initial concentration of yeast of between 0.25 and 60 g / l, preferably between 1 and 50 g / l.
  • the fermentation conditions obviously depend, to a large extent, on the yeast used and on the characteristics of the strong liquor. Fermentation is aerobic.
  • the fermentation can be carried out in fermenters of the type known for the fermentation of yeasts, that is to say in fermenters provided with a stirring and aeration device, and with a temperature regulation.
  • the fermentation temperature depends on the yeast used and is generally between 20 ° and 50 ° C. preferably between 30 and 45 ° C.
  • Agitation of the medium is carried out by any means, for example a pumping system circulating the liquor by an external loop, at a rate, for example, from 10 to 20 m 3 / h, or by a conventional agitation system such than a propeller driven by a motor (125-175 rpm).
  • This agitation also allows better diffusion of the injected oxygen.
  • Oxygen injection is carried out, for example, by injecting air through a ring pierced with holes located at the bottom of the fermenter, at a rate between 0.1 and 0.5 vvm (1 volume of oxygen / volume of liquor / minute), preferably 0.3 vvm.
  • Fermentation usually lasts from 1 h to 6 h, preferably 2 to 3 h.
  • the fermentation product is purified.
  • the fermented strong liquor is separated from the yeasts, for example, by centrifugation, which stops the fermentation.
  • the efficiency of the separation of the yeasts and the liquor is enhanced by treatment, after centrifugation, in a self-cleaning clarifier.
  • the purified strong liquor is then concentrated with a view to impregnating the base sheet.
  • the separated yeasts can be recycled as an inoculum for the following fermentations or can be used, for example, as animal feed.
  • the tobaccos which can be treated by such a reconstitution papermaking process are, in particular, all the "Virginia” type tobacco, "Bright” tobacco, coming from Brazil, China, Malawi, South Korea, Thailand, Philippines, Canada, India, Italy, Japan, USA, clouds, Zambia.
  • This flavoring treatment of strong liquor produces a reconstituted tobacco with characteristic and original organoleptic qualities.
  • the present invention also relates to the reconstituted flavored tobacco obtained by the process as well as the mixtures of this reconstituted tobacco with tobacco of different origins.
  • the reconstituted tobacco thus obtained was the subject of tasting tests by a group of specialists. Thanks to these tests, for cigarettes made up only of reconstituted flavored tobacco, we could see an improvement in certain "Virginie” notes, better “roundness” and better “balance”.
  • the fibers are separated by passage through a press 12, the strong liquor which undergoes aromatization.
  • the fibers leaving the press 12 are treated according to the conventional method to form a base sheet.
  • the strong liquor passes through a screen 20 before being treated in one of the fermenters 21 or 22 which include a stirring device and an air injection device.
  • the strong liquor passes through a centrifuge 23, then through a self-settling clarifier 24, before its concentration in an evaporation device 17.
  • the yeast is recovered at the outlet of the centrifuge and / or of the clarifier in a storage tank 25 for reuse for another fermentation or for recovery.
  • the strong flavored liquor is re-impregnated in the base sheet in the paper machine.
  • the yeast used comes from a strain Saccharomyces cerevisiae, selected as previously described; it is cultivated in a synthetic culture medium of the following composition:
  • the reactor used is a 5,000 I tank fitted with a device for circulating cold or hot water to be able to regulate the temperature. Air is injected by a crown pierced with numerous holes and located at the bottom of the tank. Agitation is ensured by a pump recirculating the liquor by an external loop at the rate of 14 m 3 / h.
  • the temperature is regulated at 36 ° C.
  • the aeration obtained is 0.3 vvm.
  • the 3,600 liters of strong liquor are inoculated with 8.7 kg of yeast, an initial concentration of 2.42 g / l.
  • Fermentation was stopped after 2 hours, including 20 minutes of centrifugation.
  • the refractometric index of the liquor was then 4% and the residual sugar concentration of 6.5 g / I.
  • the panel of tasters was able to highlight, for the cigarettes corresponding to this product, an improvement in the "Virginia” notes such as “floral”, “smoked wood” and “hay”.
  • the product had better "roundness” and better "balance”.
  • the yeast used is Saccharomyces cerevisiae, recycled after a previous fermentation.
  • the reactor used is practically the same as in Example 1.
  • the liquor was seeded with 7.87 kg of dry yeast, giving an initial concentration of 1.64 g / l.
  • Agitation is ensured by a driven propeller by a motor running at 150 rpm.
  • the temperature is regulated at 37 ° C.
  • the ventilation is fixed at 0.3 vvm, the air injection is carried out in the same way as in Example 1, but the oxygen transfer is improved by the addition of counterpales on the generators of the tank.
  • the purification is carried out by centrifugation, and the centrifuged strong liquor is then treated in a self-shedding clarifier (Westphalia @ ).
