Description
(54) SMOKING ARTICLES CONTAINING THAUMATIN OR MONELLIN
(71) We, TATE & LYLE LIMITED, a British Company, of Sugar Quay, Lower
Thames Street, London, EC3R 6DQ, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to the use of naturally occurring protein sweeteners as flavour modifiers or enhancers for tobacco smoke.
A proteinaceous material obtained from the fruit of Thaumatococcus daniellii, known as thaumatin, is a potent sweetener having a sweetness of two or three orders of magnitude higher than sucrose. In the mouth, thaumatin exhibits a distinctive long-lasting sweetness coupled with a lingering aftertaste reminiscent of liquorice. Another protein sweetener, known as monellin, is obtained from the fruit Dioscoreophyltum cumminsii. Monellin is about a quarter to half as sweet as thaumatin.
Various combinations of thaumatin or monellin with other sweeteners and s-veetness-modifiers have been reported.
Most surprisingly, we have now found that in smoking articles such as cigarettes, incorporation of thaumatin or monellin within the article itself, preferably out of contact with the mouth, causes a distinct improvement in the flavour of the tobacco smoke, the perceived flavour being smoother and more "rounded" and less harsh, with no detectable sweetening effect.
According to the present invention we provide a tobacco-containing smoking article, containing the sweet protein thaumatin and/or the sweet protein monellin at a location in the interior, whereby smoke passed to the mouth contacts the thaumatin and/or monellin. We also provide a method of smoothing and reducing the harshness of a tobacco-containing smoking article in which thaumatin and/or monellin is incorporated into the article at a location where it will come into contact with the smoke passing to the mouth.
The smoking article thus contains a sweet protein, namely thaumatin or monellin, impregnated in the fabric of the article.
The protein may be in a position so as to come into contact with the mouth, so that the protein is actually taken into the mouth to exert its effect on the smoke flavour. However, in a preferred embodiment of the invention, the protein is in the article at a location where it does not contact the mouth. We have found that, provided the protein contacts the smoke on its way to the mouth, the desired effect is achieved. This is particularly surprising, since studies with radio-labelled protein have shown that substantially all the protein in a filter tip remains in position and is not carried to the mouth by the smoke. On average, about 95% of the protein has been found to remain in situ during the smoking of a cigarette and yet produce the desired cooling and smoothing effect on the smoke. The effect is especially noticeable with American tobacco.
The smoking article may be a cigarette, cigar or pipe, and the sweet protein may be incorporated at any point in the structure of the article through which smoke passes on its way to the mouth, but which preferably is not itself in contact with the mouth. In cigarettes, the sweet protein is conveniently incorporated in the filtertip, particularly an inner cartridge between the main fikertip and the tobacco, contrasting with any use of protein in which the end of the filtertip which is inserted in the mouth is itself treated with protein. In a tobacco pipe, the protein is conveniently incorporated into a cartridge or filter to be inserted in the stem of the pipe. Small cigars, of the type having a holder or tip, can be treated in the same way as cigarettes.
Large cigars without a holder or tip, on the other hand, must have the protein incorporated internally, for example by impregnating tobacco in one end of the cigar.
The impregnation is conveniently effected using an aqueous solution. Alternatively a dry powder, e.g. freeze-dried powder, can be incorporated in the tip and then moistened to distribute it evenly throughout. The use of a tip is preferred, as the filter medium, generally cellulose acetate, appears to adsorb the protein efficiency and the size of a conventional filter tip is sufficient for uptake of the required amount of protein. After impregnation, the article may be dried in air, preferably below 50"C.
The protein does not appear to have any useful effect when burned and therefore should preferably be incorporated into the smoking article so that it does not come into direct contact with the burning tobacco.
We have found that the effect is produced by quite small amounts of protein. For example, a noticeable improvement in the roundness and smoothness of the tobacco smoke of a cigarette can be achieved by incorporating into the filter tip from 0.1 to 0.8 mg of thaumatin, preferably about 0.4 mg. The effect is provided by the free protein itself or by its aluminium adduct as disclosed in our British
Patent Applications 17831/75 and 5719/76
(Cognate), subsequently Serial No. 1,501,409.
Monellin gives a comparable effect in amounts of from 0.25 to 2.0 mg, preferably about
1.0 mg.
As a standard cigarette contains about 0.75 g of tobacco, the ratio by weight of sweet protein to tobacco is conveniently from 1:7500 to 1:940, preferably about 1:1880 for thaumatin and from 1:3000 to 1:375, preferably about 1:750 for monellin. Accordingly, larger smoking articles should contain correspondingly larger amounts of protein. For example a small cigar containing about 1.8 g of tobacco should preferably contain about 1 mg of thaumatin, while a slim panatella containing from 2 to 3 g of tobacco should preferably contain from 1.1 to 1.6 mg of thaumatin.
The effect was judged in blind trials in which tasters were asked to distinguish between five cigarettes, one or more of which was treated. The results were reproducible and showed that at the levels indicated thaumatin and monellin were both effective in smoothing and improving the flavour of the smoke. In comparison tests, other sweeteners such as sucrose, saccharin, dihydrochalcones and
Aspartame had no effect or produced a strange or unpleasant taste. Similarly other proteins such as casein and albumen produced nauseating tastes or had no effect. Amino acids, such as glycine (itself sweet) and lysine, and polysaccharides, such as alginate, also had no effect.
We have also found that the sweet protein can extend and potentiate certain flavours.
Thus, for example, incorporation of thaumatin or monellin at the above-mentioned levels into a conventional mentholated cigarette, causes the menthol flavour to be increased and made longer lasting. Alternatively the same degree of menthol flavour can be obtained by using less menthol if the protein is incorporated.
Conversely, we have also found that oil of peppermint or one of its aioma-producing components, such as menthol, can potentiate the smoothing and rounding effect of the protein, when used at levels below which its own flavour is detectable. In general, up to half the protein can be substituted by a similar weight of peppermint oil or an aromaproducing component thereof, or a mixture of the two. Thus, for example the effect of 0.4 to
0.5 mg of thaumatin in a filter tip can be obtained by using 0.2 mg of thaumatin plus 0.1 to 0.2 mg of peppermint oil or plus 0.1 mg of menthol and 0.1 mg of peppermint oil.
However, 0.2 mg of thaumatin alone had a small effect and 0.2 mg of peppermint oil or menthol alone had no discernible effect at all.
For comparison, it will be realised that a mentholated cigarette generally contains about 5 to 10 mg of menthol.
Thus, according to one embodiment of the present invention, we provide a cigarette containing a sweet protein as defined above, in which less than 1 mg of oil of peppermint and/or an aroma-producing component thereof is also incorporated. The cigarette advantageously contains from 0.1 to 0.4 mg of thaumatin or 0.25 to 1.0 mg of monellin, together with from 0.1 to 0.4 mg of oil of peppermint and/or one of its aroma-producing components especially menthol.
Example 1.
Cigarette with 2-part filter.
Cigarettes were produced experimentally by cutting open conventional 2-part filter cigarettes (e.g. "Embassy" and "Benson and
Hedges", both Registered Trade Marks) and wetting the inner part of each filter (i.e. the part which contacts the tobacco) with 0.2 ml of an aqueous solution of thaumatin
(2.0 mg/ml). The treated filters were dried in a current of air and the cigarettes reassembled.
Example 2.
Cigarette with single filter.
Cigarettes containing a single filter were cut
open and the inner end of each filter was treated with 0.25 ml of an aqueous thaumatin solution (1.6 mg/ml). The filters were dried in a current of air and the cigarettes reassembled.
Example 3.
Examples 1 and 2 were repeated, but using solutions of monellin (4 mg/ml and 3.2 mg/ml respectively).
Example 4.
Example 1 was repeated using solutions of thaumatin (1 mg/ml) containing menthol (1 mg/ml) or peppermint oil (1 mg/ml) or a mixture of the two (each 0.5 mg/ml).
Example 5.
The outer (mouth end) part of a 2-part filter is removed and the outer surface of the inner part is moistened with 0.1 ml of water or a 0.1% by weight aqueous solution of aluminium sulphate. Powdered thaumatin (0.4 mg) was then applied to the moistened surface and the filter dried. The cigarette was then reassembled.
Example 6.
Example 5 was repeated using a 10:1 by weight dry mix of cellulose or cellulose acetate and thaumatin (4.4 mg).
Example 7.
Filter.
An aqueous solution of thaumatin (2 mg/ ml) is applied to extruded cellulose acetate filaments which are dried and cut into conventionally sized filter tips for cigarettes, each containing approximately 0.4 mg of thaumatin.
