"Process for influencing the taste properties

of tobacco smoke.es "

The invention relates to a method for influencing the palatable Properties of tobacco smoke, which makes it possible within wide limits the flavor note in particular of a cigarette tobacco mixture, possibly also one Artificial tobacco foil or a neutral film, even when it fades, does not develop any components that have a negative effect on the taste To influence supporting substance.

It has already been proposed (German patent specification 1 131 580), Manufacture synthetic tobacco fibers in that a predetermined tobacco mixture an extraction treatment-under successive Extraction of water-soluble and alcohol-soluble flavorings, is subjected, through which all flavorings are obtained from to produce a dry extract of these substances and an extract made of cellulose or tylose material To mix in the carrier material, whereupon the mixture is made into strips of cross-section the natural fiber is spun.

This known method is used for the purpose of producing an artificial tobacco, which free from the woody or cellulose components

of tobacco is, and not the systematic manipulation of Taste characteristics of a given tobacco or tobacco blend.

On the other hand, this latter object is based on a known method (American patent specification 3147485) which a tobacco blend or the material from which a Cigarette filter exists or the cigarette paper determined Organic compounds should be added to avoid the inevitable differences in the nature of the Mixture components based differences of a given tobacco mixture contained in the cigarette to blend.

According to the invention, for the first time, the addition of from tobacco isolated substances for influencing the taste of tobacco blends are proposed in order to reduce the existing effect which primarily determines the aroma of the cigarette Mixture components and thus either the natural one

Total aroma of the cigarette with the same proportion of it To improve mixture components or, under certain circumstances, reduce the amount of expensive components in the tobacco mixture, without that being replenished by these additives

Flavor of the smoke is adversely affected.

The flavoring substances which are added according to the invention can be determined by examining the tobacco steam distillates in question They can be isolated from these distillates, but it is also possible to use these substances after their chemical determination by examining the tobacco water vapor distillates has taken place to produce synthetically, without then starting out from ifatur tobacco for their production got to.

These substances are used in appropriate amounts may fluctuate within relatively wide limits, and depending on their composition 5-500 parts to 1 million (ppm) can be added.

As a first group of the goal suspensions of the new procedure corresponding, in some cases such new substances, their presence in tobacco and their effect on the aroma of tobacco smoke were found to be the VinyTbenzenes, the in the 3.4.-position by hydroxyl groups, methoxy groups and the methylenedoxy groups are disubstituted, as well as those whose Vinyl group have been hydrated to the corresponding secondary alcohol group, particularly the following compounds to call:

1. 1-Hydro3cy-2-methoxy-4-vinylbenzene

2. 1-Hydroxy-2-methoxy-5-vinyl benzene

3. 1.2.-Dimethoxy-4-vinylbenzene

4. 1.2.-Methylen-dioxy-4-vinylbenzene

5. 4-Hydroxy-5-methoxy-a-phenaethyl alcohol

These substances are used alone or in a mixture in the tobacco proportional amounts of between 5 and 500 ppm, preferably 10 to 100 ppm, are added.

A second group that can be isolated from the steam distillate Clay substances that determine the aroma of tobacco smoke, includes the following compounds:

1. 4 2 · .6 · .6'-Trimethylcyelonexanone- (4 ^f ) -ylidene- (1 ^r ) -butene- (2) and the corresponding alcohol

This group of substances is already present in smaller amounts of the order of 2 to 120 ppm, which are added to the tobacco Effective in terms of the objective of the new procedure.
