Smoke-generating mixture

The invention relates to a smoke-generating mixture (hereinafter also referred to as smokable mixture) .

Furthermore, the invention does not relate to a method for improving the flavor of tobacco smoke, in particular _s, iedoch exclusively, reconstituted tobacco. The reconstituted tobacco can be any of the various types which have been described so far.

In pending British patent applications 13861/70 and 13H64 / 7O it is illustrated how the puff aroma of

109845/1632

Tobacco substitute material v / ie of smoke-producing carbohydrate, modified di carbohydrate, v / ie. it according to the in british The methods described in U.S. Patent 1,113,979 were obtained from aldol condensation products as obtained in accordance with pending British patent application 22270/69, and also of tobacco, can be improved by adding to the smokable gene, velches these smoke-producing substances, Protein and a conjugated polyunsaturated isoprenoid or its derivative added.

It was also found that adding a conjugated polyunsaturated isoprenoid itself, i.e. without accompanying protein, the smoke aroma of tobacco as such increases. This finding is of particular benefit in enhancing the flavor of smokable mixtures which are reconstituted Exhibit tobacco.

According to the invention, a smokable mixture is created, which tobacco and a conjugated polyunsaturated isoprenoid or its derivative, v / obei the ratio of isoprenoid to tobacco in the range from 1:50 to 1: 750, preferably from 1:60 to 1: 500.

As already mentioned, the invention is particularly useful to improve the smoke aroma of smokable mixtures

109845/1632

based on reconstituted tobacco.

The conjugated polyunsaturated isoprenoid is preferably a carotenoid. But it can also be a derivative of Be vitamin A.

The invention provides smokable tobacco-based mixtures with added carotenoids to enhance the smoke flavor of tobacco, which is advantageously reconstituted tobacco.

The carotenoid is preferably carotene or a derivative of carotene. Suitable carotenoids include • X-carotene, P -carotene, mixtures of -X- and ß-carotene with γ-carotene,

Lycopene, 15 .15 -dihydro - ^ - carotene, 4.4 -diketo-15 »15 dihydro - / * - carotene, Apocarotenal and apocarotinic acid derivatives, bixin, canthanxanthin and other xanthophylls.

A naturally occurring mixture of isomers, which consists of 855'ό ρ-carotene and 15 / ^ ° ί -carotin, can be used with advantage, but pure ck- or β- carotene is also suitable.

The smokable mixtures according to the invention can, in addition to tobacco or reconstituted tobacco, other ingredients included, which are normally found in smokable mixtures

used to give them the desired. physical To impart properties and firing characteristics. For example The mixtures can be glow-controlling catalysts, substances to improve the cohesion and the Ash coloring, nicotine, flavorings, drugs or humectants and film-forming binders. Alkali metal compounds can be used with advantage as glow-controlling catalysts, and salts of ammonia, alkali metals or alkali metal can be used as an ash improver. Alkaline or alkaline earth carbonates or porous fillers can add to the smokable Mixtures are incorporated in order to give them an open structure and to facilitate combustion.

In particular, additional connections can include

1. Fillers, for example calcium carbonate, magnesium carbonate. :

2. Humeetants or humectants, for example Glycerin, ethylene glycol, polyethylene glycol.

3 » Film-forming agents, for example methyl cellulose, sodium carboxymethyl cellulose, pectins, gums.

4. Smoldering catalysts, for example potassium citrate, Calcium carbonate, magnesium carbonate.

5. Ash retaining agents, for example citric acid, sodium hydrogen phosphate, tobacco extracts.

6. Solanesol, other similar non-conjugated poly-

isoprenoids and their derivatives (for example esters, acids and hydroxyl derivatives) can be added be to eiii sweet aroma of the "burning mixture and to give a pleasant aftertaste to the mouth of the tusk.

The carotene or other conjugated polyunsaturated isoprenoid is advantageously sprayed from solution onto the shredded, 'A tobacco-containing substrate. There "appears to be a synergism between tobacco and isoprenoid.

The invention will be explained in more detail with reference to the following exemplary embodiments, in which all parts and percentages are given refer to the G-ewioht.

Examples 1 and 2 illustrate the effect of carotene on a smokable mixture based on reconstituted tobacco. An improvement in the tobacco-like nature of the cigarette is observed, with a reduced side impression of the reconstituted tobacco.

Example 3 illustrates the effect of adding carotene on the levels of a normal cigarette containing chimney-treated or smoked tobacco. Examples 4, 5 and 8 pointers

109 845/1632

the effect of various amounts of carotene and Examples 6 and 7 optionally illustrate others used conjugated polyunsaturated isoprenoids.

The smoke quality of the cigarette is improved by the addition of isoprenoid, whereby a desired sweetness Note is noticeable in the smoke aroma. In each of the examples, the flavor and aftertaste of the product are used assessed by a delegation of smokers. Furthermore, in each example, those ingredients are those which are not soluble are to be regarded as finely divided *

example 1

1.34 parts of glycerin and 0.78 parts of potassium citrate, dissolved in 4 parts of distilled water are mixed with 1.92 parts of sodium carboxymethyl cellulose dissolved in 96 parts hot, distilled water, mixed. 6.73 parts of magnesium carbonate (Magnesite), 3 * 86 parts calcium carbonate and 5 »39 Parts of ball-milled tobacco are added to the above mixture and the whole is stirred until homogeneous (about 1 hour),

The slurry is poured onto glass plates and dried and gives a PiIm of 0.15 mm thickness, which is of the plates are removed, cut up and shredded. Bas Fiberized material is made with 0.001 parts of carotene in 35 parts

109845/1632

Carbon tetrachloride is sprayed and the solvent is allowed to evaporate. viexin & as treated fiber material is processed into cigarettes and smoked, it shows the improved characteristics of the tobacco taste and aftertaste, while masking the side impression, which is connected with the working method of the reconstitution .

Example 2

1.34 parts of glycerol and 0.78 parts of potassium citrate, dissolved in 4 parts of distilled water, are mixed with 1.92 parts of sodium carboxymethyl cellulose dissolved in 96 parts of hot distilled water. 6.73 parts of magnesium carbonate (magnesite), 3 _f 86 parts of calcium carbonate and 5 _t 39 parts of ball-milled tobacco are added to the above mixture and the whole is stirred until homogeneous (about 1 hour).

The slurry λ '/ ird is poured onto glass plates and dried, resulting in a film 0.15 mm thick, which removed from the plates, cut up and frayed. The fiberized material is 0.08 parts carotene in 35 parts Carbon tetrachloride is sprayed and the solvent is allowed to evaporate. When the treated frayed good too Cigarettes are prepared and smoked, so it shows improved, Characteristics of the tobacco taste and aftertaste, with the secondary impression in connection with the operation of the Reconstitution is masked
