Definitions

  • the invention relates to a process for the preparation of tobacco in which initially insoluble protein constituents and protein subunits are broken down into soluble protein fragments by enzymatic treatment and then the soluble constituents are dissolved in water and the solution obtained is separated from the treated tobacco and tobacco, prepared by this process .
  • the object of the inventive method is to achieve a processed tobacco whose content of protein components and their subunits is considerably reduced, but whose content of other soluble components is not reduced as far as possible.
  • the inventive method is characterized in that from the separated solution by metabolic assimilation caused by microorganisms and subsequent separation of the Biomass protein components and protein subunits and low molecular nitrogen compounds are eliminated and the solution components remaining in the residual solution are added to pretreated tobacco.
  • low-molecular nitrogen compounds such as amines, ammonia, nitrate and, if present, nitrite
  • the enzymatic treatment is advantageously carried out in a mixture of crushed tobacco and water in a weight ratio of 1: 3 to 1:12, preferably 1: 5. Crushed, dried, green tobacco or shredded tobacco waste can be used. If the tobacco is used in powder form, a weight ratio of tobacco to water of 1: 3 to 1: 5 is sufficient.
  • the enzymatic treatment in a slurry is advantageous because it promotes an intensive action of the enzyme on the protein components and protein subunits. On the other hand, if you use whole tobacco leaves or strips - that is, stripped tobacco leaves - you need a weight ratio of tobacco to water from 1: 8 to 1:12, preferably 1:10.
  • the optimal conditions for enzymatic treatment with regard to the tobacco-water ratio, the pH value, the solution and the treatment temperature depend on the enzyme used in each case. You may find them by trying.
  • the optimal treatment temperature for most enzymes is between 30 0 C (degrees Celsius) and 70 ° C. Many enzymes, including proteases, have an optimum at 37 ° C. There are also proteases that are most active at much higher temperatures, such as detergent enzymes.
  • the optimum pH value for many enzymes is between pH 7.0 and pH 7.5. However, the exception of the P ro- acidic proteases, such as pepsin, the pH optimum is between 1.5 and 4.
  • the optimal pH is preferably adjusted with 1 N KOH ( 1 normal potassium hydroxide solution) or 85% H 3 PO 4 (phosphoric acid).
  • the enzyme is used at a concentration which is selected so large that at the optimum for the used active enzyme treatment temperature ranging between 30 0 C and 70 ° C, optimum pH and stirring continuously before the enzyme 9/10 lost its original activity, the tobacco content of insoluble proteins and protein subunits is reduced to 20 to 40% (percent), preferably 33%, of the initial value.
  • the desired protein reduction is not achieved by the specified enzyme breakdown, then a higher enzyme concentration is expediently used; if the desired protein reduction is achieved before the specified enzyme degradation has taken place, then the enzyme concentration was set unnecessarily high and can be reduced for later batches. So it is easy to find the concentration that is advantageous for the enzyme used by trying. If the enzyme concentration is found to be optimal, the protein reduction can be done less by stopping the treatment prematurely. Then the enzyme was not used.
  • Enzymes with proteolitic activity can be used; most bacterially and mycologically formed proteolitic enzymes are suitable here. It can be pure enzymes or enzyme mixtures. A selection of suitable enzymes is given in TABLE 1 at the end of the description.
  • the separated solution is expediently sterilized and then inoculated with a culture of microorganisms which has the ability to assimilate protein and protein subunits, mainly amino acids, and has been brought into its exponential growth phase and, with the addition of sugar, favorable living conditions for them Culture is kept until at least 95% of the dissolved protein fragments and other low-molecular nitrogen compounds are used as building materials for the cell's own protein of the microorganisms. Then the metabolic assimilation is stopped by separating the biomass.
  • Sterilization and use in the exponential growth phase ensure that the selected culture is selective and is not contaminated by other microorganisms. Stopping metabolic assimilation ensures that only the desired reactions are caused.
  • Flavorings desired in tobacco smoke are formed when the tobacco burns off through the decomposition of certain amadori compounds, which in turn arise during the thermal reaction of certain amino acids with sugar. These amino acids may not be present in the tobacco treated and mixed with the residual solution in amounts sufficient for optimum aroma formation. The salaries could be replenished by adding such amino acids or Amadori compounds. But from the viewpoint that as no F remd- the tobacco materials are to be added, and also from a cost point unfavorable.
  • the invention therefore proposes to destructively hydrolyze the proteins contained in the separated biomass, the hydrolysis conditions being chosen so that those amino acids, such as tryptophan, which cannot be converted into such amadori compounds with reducing sugar and heating (Maillard reaction), which release tobacco flavors during thermal decomposition, are selectively destroyed, and then the other amino acids are reacted with reducing sugar in amadori compounds, such as, for example, aspartic acid, leucine, arginine, threonine, glutamine, glycine and valine, and that the amadori compounds thus obtained are pretreated Tobacco can be added.
  • amadori compounds such as, for example, aspartic acid, leucine, arginine, threonine, glutamine, glycine and valine
  • the solution constituents remaining in the residual solution and / or the amino acids separated from the biomass and / or the amadori compounds obtained therefrom are preferably added to the pretreated tobacco in finely divided form in an aqueous medium with subsequent drying of the enriched, pretreated tobacco.
  • a recycled, suitably as a smoking product tobacco is achieved, which is characterized by a protein content of from 2 up to 1 0, preferably 3, dry weight per cent and a AmadoriENSsgehalt from 0.1 to 10, preferably 5.0, dry weight per cent.
  • the amadori compounds are those that release tobacco flavors when thermally decayed.
  • Cigarettes made from such tobacco gave the analytical values given in TABLE 2 at the end of the description.
  • the pretreated tobacco that is the pressed strips, was dried in flowing warm air to a residual moisture content of 18% (percent) and stored.
  • the tobacco mixture to be prepared, the solution and the pretreated tobacco were analyzed analytically. This resulted in analytical values as in TABLE 3.
  • TABLE 3 shows that 58 percent by dry weight of the proteins present in the tobacco mixture to be processed has been broken down and the breakdown products have been converted into the solution.
  • the solution prepared in this way was sterilized in an autoclave at 105 ° C. under pressure and then relieved of pressure and cooled to 30 ° C. and transferred to a 20 l fermenter.
  • the 30 ° C, prepared solution was inoculated with 600 ml (milliliter) of a culture of Candida utilis NCYC 707 which is in its exponential growth phase.
  • the inoculated solution was left in the fermenter for 8 hours with aeration and stirring.
  • the pH was first stabilized to pH 5.5 with KOH (potassium hydroxide) and later with citric acid.
  • the proteins, amino acids, nitrates and nitrites were broken down by metabolic assimilation.
  • the biomass was centrifuged off. This gave 2.25 l of biomass with a solids content of 16%, corresponding to 360 g of anhydrous biomass.
  • the supernatant obtained by centrifugation - the so-called residual solution - contained the tobacco alkaloids in the originally present concentration, but beyond that only traces of soluble nitrogen compounds.
  • the total volume of the residual solution was 9.75 liters, which were kept at 20 ° C. until later use.
  • the filtered-off biomass was boiled with 1 1 6N hydrochloric acid under reflux for 15 hours in a round bottom flask.
  • the biomass disintegrated and the proteins were destructively hydrolyzed, the amino acid tryptophan being destroyed to such an extent that it was no longer detectable analytically after the hydrolysis.
  • the hydrolyzate was separated from the biomass residues by filtration, the excess hydrochloric acid escaping.
  • the dry residue which consisted largely of amino acids, was mixed with 100 ml of water and the insoluble residue was filtered off. An amino acid mixture with a water content of about 50% was obtained.
  • This amino acid mixture was adjusted to pH 7 with NH 4 0H (ammonium hydroxide) and 100 g of glucose were added and the mixture was boiled under reflux in a round-bottomed flask for 2 hours, the round-bottomed flask browning and amadori compounds being formed. The still hot contents of the flask were washed out with the previously obtained residual solution, so that the soluble amadori compounds passed into the residual solution.
  • NH 4 0H ammonium hydroxide
  • the tobacco thus obtained had or had its full original aroma and contained alkaloid nitrogen, that is to say nicotine, in the original concentration.
  • alkaloid nitrogen that is to say nicotine
  • the content of protein nitrogen was reduced by 58% and the content of amine, ammonia and nitrate nitrogen by 90% compared to the original content in the tobacco used.
  • Example 1 the Candida utilis NCYC 707 were used as microorganisms.
  • Other microorganisms which have the ability to assimilate proteins and protein subunits and which can be used instead of the Candida utilis NCYC 707 are in TABLE 5
