DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
The present invention relates to tobacco products or materials resembling tobacco products which are provided with natural substances known per se having an antioxidative effect and/or naturally identical synthetic products thereof and are intended for smoking, and to processes for the preparation of these products.
BACKGROUND OF THE INVENTION
The human body is exposed to a natural basic burden of toxic substances and is therefore confronted with a multiplicity of mutagenic and carcinogenic substances which, in the course of intrinsic metabolism, are even partly formed by the latter itself.
Man, however, has various defence mechanisms available on an immunological, cellular and genetic plane in order e.g. to counteract an allergic reaction, cell damage or a mutation event in the area of genetic information. Thus, in the cells, for example, so-called "repair systems" exist with whose aid changes in genetic material can be recognized and eliminated.
For a long time, it was assumed that there is a direct causal relationship between the action of possible risk factors such as e.g. various products of incomplete combustion, different radiations and/or electromagnetic fields, some plant protection agents and wood preservatives, certain mineral fibres (e.g. asbestos) and certain metabolic products of mould fungi (e.g. aflatoxin) on the human body and carcinogenesis. The fact that the majority of people who are exposed to these risk factors do not have the symptoms to be expected has led, however, to a rethinking in risk assessment. Thus the size of the cancer risk can no longer be defined on its own by the potential harmful substance or exposure factor. It must rather be assumed that it is the result of a multifactorial interrelationship between a multiplicity of substances/mechanisms which have an effect and the burdened body. It is further regarded as confirmed that several mutation events are necessary at certain sites in the genome in order that an abnormal cell having uncontrolled growth can be formed from a normal body cell.
Particular importance is ascribed to the body's own defence system, which can also be individually affected by the way of life. Thus, e.g. the absorption of food in the body initiates a number of chemical reactions in which substances having mutagenic and antimutagenic effects are in a close interrelationship with one another.
In the meantime, chemical compounds have been identified which have a protective action against substances having a mutagenic effect, such as e.g. different vitamins, mustard oils and beta-carotene. Naturally occurring plant phenols contained in foodstuffs, such as e.g. hydroxycinnamic acids and their compounds are also discussed as antimutagenic and anticarcinogenic substances of different intensity on account of their antioxidative properties (Karl Herrmann, "Hydroxyzimtsaure-Verbindungen als biologisch aktive Inhaltsstoffe von constituents of foodstuffs!, Ernahrungs-Umschau 38, No. 4, pp. 148-154 (1991)). These findings are supported, inter alia, by epidemiological results, which enable an inverse relationship to be detected between the consumption of fruit and vegetables and various carcinoses.
The term "tobacco products" used in this description is to be understood as meaning both cigarettes, cigarillos and tobacco cartridges (so-called tobacco-"rolls") with or without a filter and fine-cut and pipe tobacco, which consist entirely or proportionally of tobacco and/or another smokable material, and also smoking materials resembling tobacco products, such as, for example, "Kretek" cigarettes with addition of up to 50% by weight of smokable spices, or pure, tobacco-free plant cigarettes.
It is known that the consumers of smokable tobacco products also absorb a multiplicity of organic compounds, of which some have a toxic potential for the human body and others, on the other hand, can reduce this. In the discussion about the health-endangering properties of tobacco products, for a long time in particular the mutagenic and cancer-promoting ac
