Abstract

1312786 Tobacco compositions IMPERIAL CHEMICAL INDUSTRIES Ltd 19 April 1971 [23 March 1970] 13863/70 Heading A2C A smoking mixture comprises reconstituted tobacco and protein, the amount of protein to tobacco being in the range 1:2 to 1:50. Suitable proteins include the animal proteins albumin, casein, gelatine, peptone, haemoglobin or wool protein, and the vegetable proteins derived from maize (zein), wheat (glutin and gliadin), soyabean or groundnut. In the examples, aqueous slurries of ball milled tobacco together with glycerol, sodium carboxymethyl cellulose, calcium and magnesium carbonates, one of the proteins casein, gliadin or groundnut protein, and either potassium citrate or bentonite, were cast to form a sheet of reconstituted tobacco.

Description

The holder of the patent: Imperial Chemical Industries Limited, London (Great Britain) 'ni mim \ wnw m *' um »mMM.mi ¦¦nwmii-i m i uuwEgwww .miniimiij.1. l ji ¦¦ ¦¦liuiii.iipm ¦MwniuuMiumuMj.jmniw ^ —i — www — ww ^^^^ »Smoking agent The subject of the invention is a smoking agent containing regenerated tobacco from crushed waste tobacco and other known ingredients, such as organic smoke substances, binders and additives improving the physical properties and combustion. British patent specification No. 1,312,483 shows the effect of the addition of protein on the improvement of the aroma and taste properties of the smoke of the burnt smoke-producing substance, constituting the smoking substance. a substitute ingredient for tobacco, such as, for example, carbohydrates and modified carbohydrates, prepared as described in British Patent No. 1,113,979, or certain aldol condensation products. The protein reduces or completely eliminates the characteristic aftertaste and foreign smoke odor of a non-tobacco smoke and gives the smoke an aftertaste and aroma similar to that of tobacco smoke. It has been surprisingly found that the incorporation of the protein into tobacco regenerated from waste crushed tobacco formed into In the form of a sheet by means of binding agents and then crushed to give it a general use form, it significantly improves the quality of the smoke during combustion, giving it the taste and aroma of natural tobacco containing no foreign admixtures. This finding was surprising as it is known that the burned protein produces a very unpleasant, specific digital odor which is completely unlike that of tobacco smoke. According to the invention, a smoking agent consisting of tobacco regenerated from waste material. Crushed tobacco and other known ingredients, such as organic smoke, binders and additives for improving physical properties and combustion, are characterized by the addition of protein in a protein to tobacco weight ratio of 1: 2 -50, preferably 1: 8-26. Particularly suitable are animal proteins such as albumin, casein, gelatin, peptones, hemoglobin and wool protein, or vegetable protein such as corn protein (zein). wheat (glutin, gliadin), soybeans and peanuts. There are also suitable proteins derived from acid or enzymatic hydrolysis, especially casein from acid or enzymatic hydrolysis. Protein is preferably used in the state of clean, free from residual grease. The smoking composition of the present invention preferably contains, in addition to protein and smoke-producing substance, which includes regenerated tobacco, also other additional ingredients usually used in smoking substances, which affect the physical properties and the process of smoking. combustion, e.g. components that maintain the flame, improve the cohesiveness and color of ash, nicotine, aromas, medications and humectants. Ammonium, alkali metal, or alkaline earth metal salts are preferred. , ... "...,. As film forming binders, preferably methyl cellulose, sodium carboxymethyl cellulose, pectins, resins are used. In order to obtain an open texture and facilitate the combustion process, alkali metal or alkaline earth metal carbonates and other blowing fillers are used. The smoking according to the invention may contain various additional ingredients normally found in known smoking agents, such as: calcium filler, magnesium carbonate; humectants, e.g. glycerol, ethylene glycol, polyethylene glycol; film forming agents - <| ze, eg » methylcellulose, sodium carboxymethylcellulose, pectins, resins; boiling regulators, potassium hpfacitate, calcium carbonate, magnesium carbonate; ash cohesion promoters, e.g. citric acid, sodium hydrogen phosphate, tobacco extracts; agents which impart a sweet smoke flavor and aftertaste during smoking, for example, unconcined polyisoprenoids or their ester, acid or hydroxyl derivatives. In order to improve the physical, aroma and taste properties, the smoking agent may also additionally contain as an ingredient in a minor proportion one or more carbohydrates, such as fiber cellulose, starch or sugar. The invention is illustrated by the examples below, in which the parts and percentages are denote parts and percentages by weight. Ingredients which were not used as a solution were used after thorough grinding. In each example, the taste and smell of the smoke of the smoking agent were assessed by a tasting committee of smokers. Example 1 A solution of 1.34 parts of glycerol and 0.7 parts of potassium citrate in 4 parts of distilled water was mixed with a solution of 1.92 parts of dough. sodium boxymethyl cellulose in 96 parts of hot distilled water. A mixture of 6.73 parts of magnesium carbonate (magnesite), 3; 86 parts of calcium carbonate, 0.2 parts of casein protein, extracted with petroleum ether at 30 ° C for 48 hours and 5.18 parts of waste tobacco ground in a ball mill, added to the previously obtained solution and stirred for about 1 hour until a homogeneous suspension was obtained. The resulting suspension was poured onto glass plates and dried to form a film about 0.15 mm thick, which was then The resulting smoking agent was made into cigarettes which, when smoked, showed a better tobacco odor and flavor than cigarettes of the same blend but containing no protein. Example II. A solution of 1.34 parts of glycerol and 0.78 parts of potassium citrate in 4 parts of distilled water was mixed with a solution of 1.92 parts of sodium carboxy methyl cellulose in 96 parts of hot distilled water. A mixture of 6.73 parts of magnesium carbonate (magnesite), 3.86 parts of calcium carbonate, 0.6 parts of casein protein skimmed with petroleum ether and 4.78 parts of waste tobacco milled in a ball mill is added to the previously prepared solution and stirring for about 1 hour until a homogeneous suspension was obtained ... The obtained suspension was poured onto glass plates and dried to obtain a film with a thickness of about 0.15 mm, which was then shredded. The smoke was made into cigarettes. which, when smoked, had a taste and odor similar to that of cigar and pipe tobacco and which differed significantly from that of the same blend but containing no protein. Example III. A solution of 1.8 parts of glycerol in 4 parts of distilled water was mixed with a solution of 2.4 parts of sodium carboxymethyl cellulose in 96 parts of distilled water. A mixture of 5.98 parts of magnesium carbonate (magnesite), 3.74 parts of calcium carbonate, 0.4 parts of peanut protein, degreased by extraction with petroleum ether, 1.0 part of bentonite and 4.98 parts of tobacco the waste material, ground in a ball mill, was added to the previously prepared solution and stirred for about 1 hour until a homogeneous suspension was obtained. The slurry obtained was poured onto glass plates and dried to form a film approximately 0.15 mm thick which was then ground. Cigarettes were produced from the obtained smoking material which, when smoked, gave the aroma and flavor of cigar and pipe tobacco. Example 5 A solution of 1.8 parts of glycerol in 4 parts of distilled water was mixed with a solution of 2.4 parts of sodium carboxymethyl cellulose in 9 parts. distilled water. A mixture of 5.98 parts of magnesium carbonate (magnesite), 3.44 parts of calcium carbonate, 1.78 parts of casein protein, 1.0 parts of bentonite and 3.6 parts of waste tobacco ground in a ball mill. added to the previously obtained solution and stirred for 1 hour, until the obtained suspension was poured onto glass plates 40 and dried to obtain a film with a thickness of about 0.15 mm, which was then shredded. which, when smoked, gave the aroma and flavor of cigar and pipe tobacco. . . . ¦ 45 Example VI. A solution of 1.8 parts of glycerol, in parts of distilled water, was mixed with a solution of 2.4 parts of sodium carboxymethyl cellulose in 96 parts of distilled water. A mixture of 5.98 parts of magnesium carbonate (magnesite), 3.44 parts of ec, T 50 of calcium carbonate, 0.4 parts of gliadin, 1.0 part of bentonite and 4.98 parts of waste tobacco ground in a ball mill was added to the previously of the resulting solution and stirred for about 1 hour until a homogeneous suspension was obtained.
