Definitions
- ABSTRACT This disclosure is directed to a tobacco flavor enhancer from the reaction of valine with a sugar, other hydroxycarbonyl compound, or dicarbonyl compound.
- the reagents are heated in the presence of a solvent, optionally including a catalyst in the form of a flavanoid or hydroxyacid.
- a solvent optionally including a catalyst in the form of a flavanoid or hydroxyacid.
- the reaction mixture can be used directly in tobacco compositions, or can be stripped, and either or both the volatile and nonvolatile portion can be used in tobacco compositions.
- Japanese Patent No. 9,239/71 discloses the preparation of specific condensates of sugars with amino acids, which are added to tobacco products. As the tobacco is smoked the condensates are thermally decomposed and a fragrance is released.
- a further object is the production of useful substances from the reaction of an amino acid, preferably valine, and a sugar or carbonyl compound, to provide tobacco compositions incorporating such substances.
- This invention is directed to a tobacco composition cifically it relates to the reaction of an amino acid with a sugar or carbonyl compound at an elevated temperature in the presence of a solvent.
- the reaction may be carried out with or without the inclusion of a substance acting as a catalyst, which has the effect of enhancing the aroma and flavor of the tobacco to which the mixture is applied.
- the amino acid employed in the process of this invention is primarily valine, but mixtures of amino acids such as those derived by hydrolysis of proteins with a high valine content may also be used. Either optical isomer of valine is suitable in this invention.
- the reagent with which the amino acid is reacted in the process of this invention may be a sugar or other carbonyl compound.
- Preferred sugars are pentoses such as xylose, and hexoses such as glucose or fructose.
- Disaccharides such as maltose, or higher polysaccharides such as rafflnose may be used, but reducing sugars are preferred due to the shorter times and lower temperatures necessary for, running the reactions.
- Other carbonyl compounds which may be used in place of sugars are, for example, hydroxyketones, such asdihy- 2 droxyacetone, or dicarbonyl compounds such as pyruvaldehyde.
- the catalyst used-in the method of the invention may be a flavanoid, such as quercetin or rutin, or a hydroxyacid,.such as ascorbic acid.
- the solvent used for carrying out the reactions specified according to this invention may be any convenient liquid, such as polyhydroxylic solvents, mineral or vegetable oils, or water.
- polyhydroxylic solvents such as glycerol or propylene glycol are preferred, since their boiling points are in the temperature range useful in the method of the invention, and they are compatible with existing methods of tobacco processing.
- the amino acid and carbonyl compound are added to the solvent, the catalyst added, and the mixture heated to lO0-200C (preferably l20200C) for 0.5 to 5 hours, depending on the combination of materials used.
- a condenser may be employed, but is not always necessary. The re-;
- the molar ratio of amino acid tocarbonyl compound can be from about I 10.5-10, with a ratio of l:4-5 being optimum in most cases.
- the weight ratio of amino acid to the solvent used may be about 111-200, but ratios 'of' 1110- are preferred. Weight ratios of catalyst to amino acid may be 0-100 percent, but levels of 0.510 percent are preferred.
- reaction temperature for reducing sugars, hydroxycarbonyl compounds or dicarbonyl com-' pounds is l50160. This range of temperatures usually results in reaction times of 45 to 60- minutes. Higher temperatures tend to produce objectionable, burnt aromas, and lower temperatures produce inconveniently long reaction times. In the case of nonreducing sugars, such as sucrose or rafflnose, reaction rates are much lower, and higher temperatures, longer reaction times, or a combination of these must be employed.
- reaction mixtures prepared according to this invention are useful in tobacco as such, or can be further treated by passing the solution slowly through a steamjacketed column under vacuum, trapping the volatile materials in cold traps, and collecting the'solution containing the nonvolatiles separately. This is known as the stripping operation.
- the volatile portion of the reaction mixture is useful in improving the fragrance of tobacco and tobacco products, and in reducing throat irritation.
- the nonvolatile portion of the reaction mixture is useful especially in poorer tobaccos or those which have been aged for shorter than normal periods of time.
- the usefulness of this material derives principally from its ability to reduce or mask the green-grassy taste associated with these tobaccos.
- Another property of the nonvolatile part of the reaction mixtures is the enhancement of desirable flavor notes of the particular tobacco to which it is applied, while suppressing undesirable harsh, or irritating properties.
- the stripping operation is not absolutely necessary, especially if some of the more volatile materials are allowed to escape during the reaction. Nearly all of the desirable properties produced during smoking tobacco products containing these mixtures are attributable to the nonvolatile portion.
- reaction mixture may be improved by extraction with an immiscible solvent
- the above properties of the reaction mixtures are also applicable in the case of reconstituted tobacco productsv Undesirable taste properties of these tobaccos are often encountered, which are related to the green taste of poor tobaccos, or the papery taste of stem material.
- the additive has the effect of masking these undesirable tastes, reducing throat irritation and sting, and enhancing natural tobacco taste.
- the unstripped reaction mixture can be applied to tobacco in an amount equivalent to about 0.001 to 2.0 percent, based on the amount of amino acid used at the beginning of the reaction and the 4
- the following specific examples serve to illustrate the procedure used in preparing the flavorants and flavor enhancers described in this disclosure.
- EXAMPLE II A mixture of 20 g L-valine. 2 g rutin, and 24 g D- glucose was added to 200 ml glycerol and heated to 160 for 1 hour, using a reflux condenser to prevent loss of volatiles. When cooling, the mixture was passed slowly through a stripper which consisted of a steamheated glass coil connected in series to a receiving flask, two liquid air-cooled traps, and a vacuum pump. The volatile materials stripped off in the coil were trapped, and then washed out of the traps with ether. After separating and reextracting the water present in the traps, the combined ether solutions were dried over sodium sulfate, and a total solids determination showed that the volatiles weighed 470 mg.
- the nonvolatile portion of the reaction which included the glycol solvent, had a slightodor of chocolate, and weighed 253 g.
- the material which has been stripped of volatiles is also applied at these levels, but usually somewhat higher than the unstripped material.
- the volatile portion which collects in the traps during the stripping operation is useful at about 0.001 to 0.05 percent, based on its total solids content, which is determined while in ether solution.
- the methods of applying these materials are known to those practiced in the art, but basically consist of spraying or dipping, preferably theformer.
- One very convenient method is the incorporation of the material into the casing formulation and applying during the customary casing operation.
- Another method is to mix the material with ethanol or other suitable solvent and to incorporate into the top-dressing, which is then applied in the normal manner.
- EXAMPLE XV A mixture of 20 g DL-valine, 157 g D-glucose, 0.20 g rutin and 600 g glycerol was heated to 160 in an open reaction vessel, and maintained at this temperature for 1 hour, with continuous stirring. The mixture, on cooling, was diluted with 500 ml water and extracted with three 200 ml portions of ether. The aqueous-glycerol solution was heated on a steam bath for 2 hours to remove remaining traces of ether. The resulting solution had a specific gravity of 1.213. Dialysis of an aliquot against distilled water, using regenerated cellulose tubing as the semipermeable membrane, showed that 18.6 g of browning pigments were contained in the total solution.
- Example XVI EXAMPLE XVII
- the volatile portion from Example II was diluted to 50 ml with 95% ethanol.
- a 0.1 ml aliquot of this solution was diluted to ml with 50% aqueous alcohol and sprayed onto 100 g of low grade Virginia tobacco.
- Cigarettes made from this tobacco had an accented Virginia tobacco taste.
- EXAMPLE XVIII A solution of 0.05 g of the nonvolatile (stripped) portion from Example II, in 1 ml of 50% aqueous alcohol, was sprayed onto 100 g of low grade Virginia tobacco. Cigarettes made from this tobacco exhibited a reduction of the green-grassy taste noticed in the control cigarettes. The mixture also produced a rounding of the flavor and a much smoother smoke.
- Example XIX The procedure of Example XVIII was repeated using a low grade Burley tobacco. The cigarettes made from this tobacco displayed a reduction in impact and sharpness when compared to a control, and the desirable burley fragrance was enhanced.
- Example XX The procedure of Example XVIII was repeated using reconstituted tobacco. The cigarettes prepared from this tobacco, when compared to control cigarettes, had
- Example XXI The procedure of Example XX was repeated, except that a solution of 0.1 g of the nonvolatile portion in 1 ml 50% aqueous alcohol was used. Cigarettes prepared from this tobacco exhibited enhanced tobacco taste, along with reduced throat irritation and mouth pepperiness.
- EXAMPLE XXII A solution of 0.1 g of the mixture prepared as set forth in Example XI, in 2 ml 50% aqueous alcohol, was sprayed onto I00 g of a cased and cut commercial blend of tobaccos and evaluated as in Example XVI.
- the smoke from cigarettes thus prepared showed a noticeable reduction in impact and amplitude, and a slight reduction in the oak-leaf taste associated with reconstituted tobacco.
- the flavor showed less pepperiness and was somewhat sour.
- EXAMPLE xxm A solution of 0.1 g of the mixture prepared as set forth in Example XIV, in 2 ml 50% aqueous alcohol, was sprayed onto g of a commercial blend of tobaccos and evaluated as in Example XVI. The cigarettes produced a slightly lower impact and amplitude of flavor than the untreated control, with an increase in sour-green notes.
- EXAMPLE XXIV A solution of 12 mg of the pigments isolated as described in Example XV, in 2 ml of a 50% aqueous alcohol solution, was sprayed onto 100 g of unflavored cut tobacco, and cigarettes prepared accordingly. The smoke produced by these cigarettes was described by the flavor panel as having a lesser degree of harshness and irritation than a similarly prepared control, with better balance, and more sweet taste and tobacco fragrance.
