Cigarettes as Tobacco Products
Tobacco as a consumer product is a very unique plant material. It can not be attributed to a group of plant products, conventional flavoring matter. By the nature of consumption and the effect on the human body it is very different from the rest of the taste of vegetable origin and contain alkaloids (tea, coffee, etc.). The quality of tobacco in taste and pharmacological relationship only partly depends directly on its chemical composition. To a large extent it is determined by the combustion and distillation, which are formed from the components of tobacco in his burning and absorbed by the body during smoking.
Due to the different nature of combustion, which depends not only on the physical-chemical properties of tobacco, but also on the conditions of the flow of air to the burning zone, obtained qualitatively and quantitatively different mixtures of products of combustion and destructive distillation. These differences are reflected both in taste and in the physiological action of tobacco smoke on the human body. In addition nicotine tobacco contains substances that are depressing the nervous system. In general deleterious effect on the human body has no nicotine, and the combustion products of tobacco - tobacco smoke. In the combustion of tobacco produced two types of jet smoke: the main and side. The main stream smoke is formed in the burning cone of tobacco products during the puff, pass through the extrusion and tipping out of the end product. Side stream is formed at the time between puffs and released into the environment. The main stream of cigarette smoke is composed of tightly condensed aerosol, which is a sub-micron particle size of wet down to 0.3 microns, which is often called condensate or tar.
The peculiarity of tobacco is physiological strength, which accounts for its narcotic effect. Physiological strength tobacco increases with nicotine in it. As a rule, high-quality raw materials and in the higher grades of tobacco products, nicotine is less than in medium and low grades. Physiological strength of tobacco smoke is a property that allows you to ensure saturation of the smoker and the normal duration of the intervals between smoking cigarettes, cigarettes, etc. For an objective assessment of quality of tobacco products must be in sufficient detail to determine not only the physical and chemical structure of the tobacco, but also the products of combustion and destructive distillation.
Tobacco products have a wide range, as well as a wide variety of flavors and aromatic properties. The greatest demand among tobacco products belongs to cigarettes. Cigarettes can be of the first, second, third, fourth, fifth, sixth and seventh grades. The higher is the class of cigarettes, the harder and more intense aroma and taste of smoke are, less nicotine content and richer look and feel. At lowering grade of cigarettes, their strength flavor is increasing. Flavor strength tobacco smoke is a measure of the degree of irritation of tobacco smoke on the airways smoking. The most popular cigarettes brands are Kent, Winston, Parliament, Camel cigarettes. Their quality along with cheap cost have earned smokers' recognition for many decades.
The aroma of tobacco smoke is improved by adding shredded tobacco, alcoholic solutions of essential oils, synthetic substances such as vanilla, food essences and similar substances - air fresheners. This process is called aromatization of tobacco. To soften the taste of tobacco smoke tobacco leaf before cutting impregnated with aqueous solutions of substances that are rich in carbohydrates, which the combustion affect the taste and the aroma of smoke.
