Smoking content substance containing fruit matter {SMOKABLE FILLER MATERIAL CONTAINING A FRUIT MATERIAL}

For a long time, filler materials suitable for use as tobacco substitutes have been proposed. And very few studies have been made on the use of substances extracted from fruits. Where fruit is used, the fruit is generally a minor component added to provide sugars and amino acids or can be found, for example, in British patent specification 1,412,878 for fruits as structure-formers. The main organic combustor, for example the main fuel material in this specification, is selected from waste products of rice hulls, straw, sesame or husks, for example cereals or tree nuts.

For example, inorganic non-combustible binders such as Portland Cement may be used. The above can also be used in combination.

If the binder is an alginate, in particular monovalent alginate, in the treatment step, the pH of the slurry should be maintained in the range of above 5 and below 3, for example 3-5, in order to improve the binding properties of the alginate. This can be achieved, for example, by adding a basic substance such as sodium carbonate or an acidic substance such as citric acid to neutralize the slurry or by equilibrating the fruit and mineral content contents.

Fruity substances are suitably, for example, fruit residues produced in the preparation of fruit juices, fruit fasts, fruit purees, powdered extracts of fruits or liquid extracts of fruits, all fruits, dried fruits, fruit pulp, fruit condensates. It is a substance extracted from one or more fruits. If liquid extracts are used, the extracts are preferably not purely sugars from the fruit. Mixtures of each class are also acceptable. For example, a fruit liquid or syrup is mixed with the mineral contents, dried, and granulated grains of the fruit material into granules are advantageous for some fruit derivatives in terms of ease of processing.

The fruit powder or condensate is mixed with water until each is completely dissolved. The pulp from the fruit is finely divided and the fiber is properly milled so that the fiber is still intact. The fibers can be separated from the liquid so that the ratio of fiber to liquid is changed as needed. In the case of utilizing dried fruits, the fruits are preferably boiled in water. In the case of utilizing high sugar fruits, they are boiled well, filtered and then mixed to produce a homogeneous mixture or fast so that, for example, the ratio of organic acid and sugar is lost.

The extrudates are rods, strands, filaments or sheet materials that are then chopped to provide the contents material. Entwining or twisting the strands or filaments is desirable to provide an air passage if the extruding material does not allow the extraction of air or smoke following it. Other downstream flow treatment techniques may also be used to enhance the pressure drop if required as extruded rods. Various extrusion forms are described in the PCT application, which is taken herein by reference.

In addition, the smoke content material also includes a burn additive to enhance the smoking performance of the content material. Depending on the nature of the contents, the combustion additive may be either a combustion enhancer or a combustion retardant.

The following examples are described below to facilitate understanding of the present invention.

Example 1

The general process is described below.

Initially, water, glycerol and choke are mixed thoroughly using a Silvererson mixer until a homogeneous slurry is produced. Fruit powder or condensate is mixed separately with a small amount of water and mixed until completely dissolved. If dry fruits are used, the fruits are boiled in tap water for 20-30 minutes and mixed in a food processor until a homogeneous fast is produced. Percolation to remove organic acids and sugars may be desired depending on the sugar content of the fruit.

Add fruit fasts or fruit solution to the chalk slurry and mix. It is known that a low pH has a detrimental effect on the binding properties of sodium alginate or ammonium alginate binders, after being chopped, resulting in poor quality sheet materials that cannot be used to operate reliably through tobacco makers due to their reduced strength. Therefore, it is important to control the pH, depending on the alginate binder used.

Finally, the binder gradually adds more water to the mixture as needed. The final viscosity of the slurry should ideally be between 150,000 and 250,000 centipoise.

The slurry in the following example is cast in a drum casting machine to produce a consistent sheet. The resulting sheet is stored at approximately 60% RH for 24 hours prior to the shredder operation using a Hauni tobacco shredder or paper type shredder. After the strands have been adjusted for 48 hours, the material is ready to be made into tobacco in a cigarette maker.

Example 2

As a representative sample, three classes of fruit are used to produce a smoking content material. Pineapple condensate (75 ° BRIX) from HAX Limited, London, UK, powdered mango extract from Key Ingredients Limited, Cheltenham, and raisins (whole fruit) from Tesco supermarket Each is processed separately and chopped appropriately. Each proportion of the material is: 7.5% fruit material, 12.5% sodium alginate binder, 70% coarse choke mineral content and 10% glycerol aerosol former.

Each chopped material is constructed of a 5CU paper wrapper with 24.70mm diameter, 64mm length tobacco with a 20mm cellulose acetate filter and 0.55% potassium citrate combustion additive added thereto. This tobacco composition can in this case be directly contrasted with a king size, full flavor, Virginia style control cigarette.

Cigarettes are smoked on standard equipment with a 35 ml inhalation of 2 seconds per minute. Statistical relative numbers of cigarettes are smoked (see Procter, C et al., “The Analyst” (October 1988, 113, 1509-1513)). In this case, the average of four ports and one pad per port. Take five cigarettes.

The smoke emissions from the main stream are shown in Table 1, along with the rate of attainment reduction in emissions compared to the control cigarette (see Table 2).

Example 3

The other experimental mixture produced had the following samples.

As can be seen from the above sample, the smoking content material according to the present invention has substantially a significant smoke emission advantage.

The table shows a sharp dilution especially in the smoke emissions of the main stream and the side stream.

Moreover, the material is also well implemented in conventional tobacco production situations and does not require modification of existing devices.

Low smoke in the nitrogen extraction compound is obtained. Surprisingly, a low dry particulate content of the smoke is also obtained. Despite the high level of non-combustible mineral content, substantially smoke aerosols occur mainly containing glycerol and water.

The final product also provides a product of low nitrogen and average ammonia nitrogen (shown in Table 4).

Example 4

The general process is described below.

Dry mixtures are prepared from choke (50%), dried or powdered fruit (20%), pregelatin starch (20%), and hydrooxypropyl cellulose (10%). The mixture is then sent to an extruder where water and glycerol (3-5%) are pumped into the extruder. The extruder barrel is heated at points along the barrel to produce a temperature in the heated extruder zone, which is generally at 70, 100, 110, 120 and 130 ° C. In general, the pressure at the die is about 30 bar and in any case should be less than 100 bar. The squaw contour of the extruder must be such that sufficient energy is applied to the mix to produce a blown extrudate as the material exits the extruder die. The extrudate formed is in the form of a tube or foam sheet. Ideally, the tube would have a very small diameter hole running longitudinally through the center.

The extrudate is conveyed away from the extruder die with a suitable suction system.
