The invention relates to a smoking material with cereal grain components.

From DE-OS 22 10 255 a method for processing low-wood nocturnal tobacco plants, for example cereal grains, for tobacco substitutes is known. at In the process described there, a homogeneous pulp is formed from the plant matter, which is supplemented by additives, shaped into a tobacco substitute and is dried.

However, the intended deformation does not lead to a cereal product that can be described as "expanded".

Processes for expanding a starch-containing dough product are known from US Pat. No. 2,701,200 but do not recognize any connection to the production of a smoking material.

Finally, the US-PS 35 24 451 should be mentioned from which it is known by the filling capacity of tobacco to increase an expansion process.

The invention is based on an object To produce smoking material from which cigarettes and cigars as well as pipe tobacco can be produced, whereby the taste and aroma should not differ from pure tobacco, on the other hand but the tar and nicotine content is lower.

This object is achieved according to the invention by the In the characterizing part of claim I specified features.

Refinements result from the subclaims.

The following examples are intended to illustrate the advantages of the present invention. For these examples, the bulk density of the tobacco stretchers according to the invention was determined by weighing a known volume of the expanded material - as previously described. In all cases, however, the bulkhead weight was less than 0.40 g / cm ¹ , when determined with the 12 sieve.

example 1

5 ml (20% by weight) of an aqueous calcium chloride solution and 2.5 ml were added to 13 g of shredded puffed rice (20% by weight) of an aqueous potassium carbonate solution. The treated material was exposed to air dried and then 70 mm Zlgaretten in made by a small cigarette machine. The average weight of the cigarette was 0.34 g and that average pressure drop across the 70 mm was 45.4 mm water column. Under standard FTC conditions became one with every cigarette on the smoke machine average number of moves of 3.5 received.

Example 2

The bulk weight was determined from the total puffed rice which had previously been stored at a relative humidity of 50 to 60% until an equilibrium moisture content of 8 to 10% was reached. The puffed rice was then ground in a mixer (Warlngblender) and sieved. Various particle sizes were collected and the bulk density was determined by weighing 50 cm ^{1 of} the uniformly packed material. Packing was accomplished by tapping the bottom of the container at intervals during packing so that the particles sagged to SO. No external pressure was applied to the particles. The densities of the material are shown in Table I. As a comparison, the densities of selected tobacco are shown in Table II.

These tests show that the puffed rice smoking material is very expanded and low in density Bulk weight is. Compared to tobacco, which is commonly used to fill cigarettes.

Example 3

The filling capacity of puffed rice was determined. The shredded puffed rice was brought to a size of 32 strips (schnitzel) per 2.54 cm and thus corresponded very well to tobacco strelves or tobacco shreds. In order to measure the filling capacity of the Zlgarettenfüllmaierlals, a measuring device was used which consisted of a 100 ml graduated cylinder, which had an inner diameter of 25 mm and was provided with a piston, the diameter of which was about 24 mm. The weight of the piston movable in the cylinder was 802.5 g. A 3 g sample was placed in the cylinder and the piston was placed over it. The gravitational force acting on the piston and thus the tobacco corresponded to a pressure of 0.162 kg / cm ² . The fill value of the sample is the volume value to which the 3 g sample has been pressed by the plunger after an exposure of 3 minutes. This pressure is almost the same as that normally exerted by the cigarette paper on the tobacco in the cigarette.

According to this method, the filling capacity of the puffed rice was determined to be 40.3 ml per 3 g sample at a moisture content of 9.22 *.

Example 4

Cigarettes were made from shredded puffed rice by mixing 20 vol .- * or 50 vol Vol .- * rice with 80 vol .- * or 50 vol .- * conventional cigarette tobacco. From the Tabek / Puffrels-Mlschung cigarettes were made. The resulting 65 mm long cigarettes were combined with a 20 mm long 3.3 / 39,000 cellulose acetate filters connected and the finished cigarettes smoked under FTC standard conditions. The following results were obtained:

The material thus treated was air-dried and 70 mm cigarettes were made in a cigarette machine. The average twist of the cigarettes was 0.36 g and the average pressure drop over the 70 mm length was 6.4 mm water column. Under the standard FTC conditions, an average puff number of 4.0 was obtained when smoking the cigarette automatically.

Example 6

It was the bulk weight of the entire puffed wheat, which was previously at 50 to 60 * relative humidity up to Equilibrium moisture content of 8 to 10% had been stored. The puffed wheat was then in ground and sifted in a mixer. Numerous particles were collected, and of this it became the Bulky weight determined by weighing one evenly packed material of 50 cm ³ .

than comparable cigarettes made only from tobacco. Example 17

A hexane extract from smoke-treated tobacco was obtained. In the subsequent concentration of the extract by removing the hexane, the extract was dissolved in ethanol and shredded popcorn with a bulk density of 0.05 g / cm ^! given up. The ethanol “could then evaporate. The amount of extract obtained from 1 g of tobacco was sprayed onto 1 g of shredded popcorn. The treated tobacco was mixed with recycled tobacco. The composition was 75% popcorn and 25% (vol.) Tobacco. This mixture was used to make cigarettes. The panelists found that the cigarettes burned satisfactorily and were certain to be smoked with a lower degree of irritation when compared to cigarettes made from recycled tobacco.

Example 18

Shredded popcorn with a bulk density of 0.05 g / cm ¹ was mixed with ordinary pipe tobacco. One mixture contained 12.5% by volume popcorn and the other mixture contained 25% by volume. The evaluation by the test persons was carried out as indicated below.

«Ben:

no difference between ordinary pipe tobacco and the mix with 12.5% by volume popcorn; the 25% popcorn mix appeared slightly milder and had no off-taste. Both mixtures burned less than the usual pipe tobacco.

Example 19

Conventional cigarettes were cut open and the tobacco removed. A lot of 171.4 g of this Tobacco was extracted with ethyl alcohol and the alcohol was then removed, leaving 46.8 g of extract were obtained. This extract was brought into solution with 500 ml of ethyl alcohol. About 55 ml of the The extract in the alcohol solution was mixed with 265 ml of ground popcorn. The size of the popcorn was such that the particles passed through a 10-mesh sieve but remained on a 20-mesh sieve and

the bulk density measured was 0.065 g / cm ³ . The alcohol was then allowed to evaporate over a period of a few days. This left a brown coating on the ground popcorn.

The coated popcorn was then in volume ratio of 50:50 with the same cigarette tobacco mixed from which the extract was obtained. The mixture was rolled into cigarettes, on a top hand operated device using top cigarette paper. Cellulo acetate filters were added to the cigarettes scheduled. The finished cigarettes were tested and found to be very soft, non-irritating, free from nasal burning and very tasty.

Example 20

Bulk weight measurements were carried out on popcorn, this beforehand at a relative humidity of 50 to 60 "* until an equilibrium moisture content is reached 8 to 10% had been stored. The popcorn was ground in a mixer and sifted. Various particle sizes were collected and the bulk density thereof became determined by weighing a 50 cm 'volume of uniformly packed material.

The bulk density of puff triticale was determined, again with storage beforehand a relative humidity of 60 *. until the achievement an equilibrium moisture content of about 8% took place.

Triticale is a well-known hybrid of wheat (genus TriticunO and rye (genus Seeale),

The determination was carried out as indicated in Example 2. The results and comparative results are in the Tables XIX and XXI listed:

The results show the high expansion and the low bulk density compared to tobacco, the usually used to fill cigarettes.

Example 35

It became the filling capacity of puff triticale like Im Example 3 described determined.

The 3 g sample with a moisture content of 8.30% had a fill capacity of 42.4 ml.

Example 36

Shredded puff tritlcale turned into cigarettes by mixing 20% by volume or 50% by volume of triticale

with 80% by volume or 50% by volume of conventional tobacco manufactured. The 65 mm long cigarettes were fitted with a 20 mm long 3.3 / 39,000 cellulose acetate filter. The results are shown below:

20 VoI, - * Cigarettes containing Puff-TriUcale were made smoked by experts in comparison with cigarettes containing pure tobacco. 45% of the people gave the test cigarettes the before train or but made no difference between the Test and control cigarettes in terms of preference.

35% stated that the test cigarettes were milder selenium, while 25% saw no difference in mildness ten. A better overall taste was the test ziga save awarded to 30%.

In summary, it is stated that the described, expanded Materlallen and according to the invention Tobacco has numerous benefits.

J3 From an economic point of view, it's not just that resulting lower tobacco consumption beneficial, but also the reduction in nicotine. The so-called tar proportions are also lower, as the TPC content is generally lower than that of tobacco. The Nlkotin- Free expanded grains are easy to manufacture, easy to obtain, relatively low in cost, and do not affect the taste or aroma of tobacco products. The expanded material does not crumble, it falls

* "> when smoking the cigarette do not stick together and do not impede the burning or drawing.
