The taste of tea, coffee and lime-flower tea can be modified; the additives may be used in meat, esp. smoked meat, and cocoa.

Description

  

  
 



   II est bien connu que le tabac destine à la   preparation    de cigarettes, par exemple, est essentiellement constitué par un melange de   different    types de tabac, ledit   melange      etant    néces- saire pour produire un goût et un   arose    caractéristique lorsque le tabac est fumé.



   Les tabacs pour cigarettes qu'on trouve actuellement dans le commerce sont en effet constitues pour la plupart par des melanges de tabac de Virginie, de Maryland ou Kentucky, et de   differents    types de tabac dans lesdits   melanges    sont variables et sont fonction du   gout    et de l'arôme qu'on   desire    obtenir. Une pratique couramment employée aujourd'hui consiste à ajouter auxdits melanges des substances additives telles par exemple des substances aromatisantes et humectantes.



   Par l'utilisation selon la présente invention on peut mettre   9    la disposition du consommateur un tabac a fumer qui   presente    des caractères organoleptiques améliorès par rapport au tabac de base.



   La présente invention consiste en effet en l'utilisation comme agents aromatisants pour l'aromatisation d'un tabac d'origine naturelle ou artificielle d'au moins un compose chimique   synthé-    tique de formule:
EMI1.1     
 dans laquelle chacun des restes RÚ et R2 représente soit un reste monovalent   derive    d'un hydrocarbure aliphatique   saturn    ou instauré, linéaire ou ramifié ou d'un hydrocarbure aliphatique cyclique, soit l'un d'eux représente un reste acyle et l'autre un reste monovalent indiqué ci-dessus ou l'hydrogène. conjointement avec au moins un compose cétonique et ou aldéhydique appartenant à l'un des groupes définis ci-après:

  :
EMI1.2     
 dans laquelle R  et R4   reprasentent    soit des restes alcoyles soit l'un d'eux   l'hydrogène    et l'autre un reste alcoyle;
 B
 R5-CO-R6 III dans laquelle chacun des restes   R,s    et R6   reprasente    soit un reste monovalent derive d'un hydrocarbure aliphatique   saturn    ou instaure. linéaire ou ramitié ou d'un hydrocarbure aliphatique cyclique. soit l'un d'eux représente l'hydrogène et l'autre un reste monovalent tel qu'indiqué ci-dessus:
 C   R5-CO-[CHn=CHn]m-CO-[CHn=CHn]@-[CO]@-R6    (IV) contenant des liaisons simples ou doubles dans les positions indi   quees    par les pointillés. et dans laquelle:
 i) les indices m et p représentent un nombre entier compris
 entre zéro et 10,
 ii) n vaut un ou 2.



   iii) q vaut zero ou 1. et
 iv) les substituants   RS    et R6 ont le même sens que celui indiqué
 pour la formule III;
 D divers:

   2-acétonyl-3-isopropyl-6-méthyl-tétrahydropyranne,
 1-acétyl3-3-isopropényl-cyclopentane,
 4-méthylthio-2-butanone,
 phénylacétaldéhyde et
 cinnamaldéhyde.



   Les composes mentionnés ci-dessus ont   Cte    divisés en groupes qui tiennent compte de leur analogie de structure chimique plutôt que de leurs propriétés organoleptiques, cellesci peuvent en effet être   tres    variées et sont fonction de la nature des autres composants du mélange aromatisant considéré.



   Les composes chimiques dont l'utilisation constitue l'objet de la présente invention peuvent être mis à la disposition des aromatiseurs sous une grande variété de formes. Il est préférable d'utiliser lesdites compositions sous forme de solution. Cependant, la nature chimique du compose considéré, sa solubilité, sa stabilite détermineront la forme de la composition dans laquelle il pourra être employé.



   Une   méthode    couramment employee pour procéder à l'aroma- tisation du tabac consiste   Åa    asperger une solution alcoolique des composes aromatisants considérés sur du tabac déjà   couple.    A cet effet des mélanges   d'alcooleau    ou de propylènegycol constituent des solvants convenables.



   Les proportions suivant lesquelles ces composés peuvent   etre    utilisés pour produire des effets aromatisants, peuvent varier entre des limites très éloignées les unes des autres et   dependent    tout particulièrement de l'effet recherché et de la nature même du produit que l'on utilise. C'est ainsi que, par exemple, des proportions de l'ordre de 100 ppm par rapport au poids total du produit   Åa    aromatiser peuvent déjà produire des effets organoleptiques intéressants. Ces proportions peuvent aller jusqu'a 5 ou 10% du poids total du produit   Åa    aromatiser.



     II    est bien entendu que les proportions données ci-dessus ne représentent pas des limites absolues et des concentrations représentent rieures ou infé- à celles supèrieures peuvent etre   utilises.   



   Dans la description indiquées suivante des composes faisant partie des groupes indiques plus haut on donne d'abord la formule structurale. suivie par une liste des membres du groupe spécifique des propriétés excellentes pour cette dite utilisation.



     Immediatement    après la designation chimique de chaque membre, on a indiqué la source commerciale ou les   references    de litterature donnant la méthode de leur préparation. Les produits disponibles dans le commerce sont identifiés par l'abréviation  p.c. . et ils peuvent être achetés chez Fluka AG. Buchs SG, Suisse; Eastman

   L'utilisation suivant l'invention est illustrée d'une manière plus détaillée par les exemples suivants.



  Exemple 1:
 On a   prepare    une composition aromatisante en mélangeant les
 ingrédients suivants (parties en poids): acétylpyrazine à 10% *.. .............. ..... .. 0.15 2,6,6-triméthyl-1-trans-crotonoylcyclohex-1-ène à 10% *. 0.10 p-méthyl-acétophénone.. 0,65   α-ionone à 10%*. 0,65    géranylacétone.. 0,15 hexahydropseudoionone. 0,05 rhum....... ........ 3,85 alcool éthylique à   95% ..    4.40
 10,00 *dans l'alcool éthylique à 95%
 On a aspergé un mélange de tabacs du type    american    blend (100 g) avec 10 g d'une solution   9      100    de la composition aromatisante précitée dans de l'alcool à 95%.

   Le goût des cigarettes préparées avec du tabac ainsi   aromatii    a été défini comme etant   caractérisé    par une note verte, fleurie, boisée, légèrement fruitée. 



  
 



   It is well known that tobacco intended for the preparation of cigarettes, for example, consists essentially of a mixture of different types of tobacco, said mixture being necessary to produce a characteristic flavor and aroma when the tobacco is smoked.



   The tobacco for cigarettes currently on the market are in fact made up for the most part by mixtures of tobacco from Virginia, Maryland or Kentucky, and different types of tobacco in said mixtures are variable and are a function of taste and taste. the aroma we want to obtain. A practice currently employed today consists in adding to said mixtures additive substances such as for example flavoring and humectant substances.



   By use according to the present invention, a smoking tobacco can be made available to the consumer which exhibits improved organoleptic characteristics over the basic tobacco.



   The present invention in fact consists in the use as flavoring agents for flavoring a tobacco of natural or artificial origin of at least one synthetic chemical compound of formula:
EMI1.1
 in which each of the radicals RÚ and R2 represents either a monovalent residue derived from a saturated or established aliphatic hydrocarbon, linear or branched or from a cyclic aliphatic hydrocarbon, or one of them represents an acyl residue and the other a monovalent remainder indicated above or hydrogen. together with at least one ketone and or aldehyde compound belonging to one of the groups defined below:

  :
EMI1.2
 in which R and R4 represent either alkyl residues or one of them hydrogen and the other an alkyl residue;
 B
 R5-CO-R6 III in which each of the residues R, s and R6 represents either a monovalent residue derived from an aliphatic saturn or instaurated hydrocarbon. linear or branched or a cyclic aliphatic hydrocarbon. either one of them represents hydrogen and the other a monovalent residue as indicated above:
 C R5-CO- [CHn = CHn] m-CO- [CHn = CHn] @ - [CO] @ - R6 (IV) containing single or double bonds in the positions indicated by the dotted lines. and in which:
 i) the indices m and p represent an integer included
 between zero and 10,
 ii) n is one or 2.



   iii) q is zero or 1. and
 iv) the substituents RS and R6 have the same meaning as indicated
 for formula III;
 D various:
 8-hydroxy-8.9-dihydrocarbon.



   piperitone.



   2-acetonyl-3-isopropyl-6-methyl-tetrahydropyran,
 1-acetyl3-3-isopropenyl-cyclopentane,
 4-methylthio-2-butanone,
 phenylacetaldehyde and
 cinnamaldehyde.



   The compounds mentioned above have been divided into groups which take into account their similarity in chemical structure rather than their organoleptic properties, these can in fact be very varied and depend on the nature of the other components of the flavoring mixture considered.



   The chemical compounds the use of which constitutes the object of the present invention can be made available to flavorers in a wide variety of forms. It is preferable to use said compositions in the form of a solution. However, the chemical nature of the compound considered, its solubility and its stability will determine the form of the composition in which it can be used.



   A commonly used method of flavoring tobacco is to sprinkle an alcoholic solution of the flavoring compounds under consideration on already paired tobacco. For this purpose, mixtures of alcohol or propylene glycol constitute suitable solvents.



   The proportions according to which these compounds can be used to produce flavoring effects, can vary between very distant limits from one another and depend very particularly on the desired effect and on the very nature of the product which is used. Thus, for example, proportions of the order of 100 ppm relative to the total weight of the product to be flavored can already produce interesting organoleptic effects. These proportions can range up to 5 or 10% of the total weight of the product to be flavored.



     Of course, the proportions given above do not represent absolute limits and concentrations greater or less than those above may be used.



   In the following description given of the compounds belonging to the groups indicated above, the structural formula is first given. followed by a list of members of the specific group of excellent properties for this said use.



     Immediately after the chemical designation of each member, the commercial source or literature references giving the method of their preparation are indicated.
