Abstract
The present invention relates to a reconstituted vegetable sheet suitable for use in a device for heating tobacco without burning the tobacco, said reconstituted vegetable sheet comprising one or two fibrous carriers obtained by a paper making process and comprising vegetable fibres, a vegetable extract and a solid additive.
Description
Technical Field
The present invention is in the field of devices for heating tobacco without burning it, and the subject of the invention is reconstituted vegetable pieces obtained by a papermaking process and containing solid additives.
Background
To avoid the formation of harmful constituents during the combustion of tobacco, a number of devices have been developed for heating tobacco without combusting the tobacco. As an example, applications published under the numbers WO 2016/026810 and WO 2016/207407 describing this device can be mentioned. In these devices, tobacco is combusted by heating it at a temperature below the combustion temperature, which results in the formation of an aerosol. The aerosol generated during heating of the tobacco replaces cigarette smoke, has favorable organoleptic properties, and is inhaled by the user. This therefore allows the user to inhale the aroma of the tobacco, while greatly reducing the user's exposure to harmful ingredients.
Conventional tobacco is not suitable for use in such devices because it does not produce a large amount of aerosol with favorable organoleptic properties. Reconstituted tobacco is more suitable for use in these heating devices because it can produce a large amount of aerosol with favorable organoleptic properties.
However, it is still important to have good control over the amount of tobacco aroma in the aerosol formed so as not to create a sense of frustration among users of the heating device. It is also advantageous to provide a user of the heating device with a scent other than tobacco.
In order to diversify the aroma and control its content in the aerosol, solid additives may be added to the reconstituted tobacco. However, this poses the problem of loss of the solid additive added to the reconstituted tobacco.

-1 or 2 fibrous carriers comprising plant fibers,
-a plant extract, and
-a solid additive.
If the reconstituted plant sheet of the invention comprises 1 fibrous carrier, the additive is attached to the carrier by means of a plant extract. Thus, the loss of additives from the reconstituted plant pieces of the invention is advantageously minimized.
If the reconstituted plant sheet of the invention comprises 2 fibrous carriers, the additive is entrapped between the 2 fibrous carriers and the plant extract makes it possible to attach the 2 fibrous carriers to each other. Thus, loss of additives from the reconstituted plant pieces of the invention is minimized.

2) Characterization of reconstituted tobacco sheets
The weight content of dry matter of plant fiber, plant extract and plant dust in the reconstituted plant pieces is shown in the table below.
The reconstituted plant pieces were subjected to the Buroma cut test.
The loss of plant dust was 2.6%, very low.
The reconstituted tobacco sheet obtained is then shredded so as to be smokable without burning. The sensory properties of the resulting aerosol are satisfactory to the user.
Example 2: reconstituted tobacco sheet, wherein n is 2
1) Obtaining reconstituted tobacco sheets
Basis weight of 32g/m was obtained by feeding tobacco into a paper machine2Two fibrous carriers of (4).
Then, 2.7g of peppermint dust was dusted onto the wet side of one of the two fibrous carriers. The thus obtained spread fibrous support is then dried.
Then, stacking of the second fiber carrier and the scattered and dried fiber carrier is performed by attaching the wet side of the second fiber carrier and the surface of the scattered and dried fiber carrier in contact with the plant dust to form a sandwich of fiber carriers in which the dust is trapped between the two fiber carriers.
Then, Rapid is used
The apparatus dries the sandwich of fibrous support.
Then, the interlayer of the dried fibrous carrier was impregnated with 3.64g of the tobacco extract and glycerin to obtain an interlayer of the impregnated fibrous carrier.
The sandwich of impregnated fibrous supports was then dried at 90 ℃ for 540 seconds.
2) Characterization of reconstituted plant pieces
The weight content of dry matter of plant fiber, plant extract and plant dust in the reconstituted plant pieces is shown in the table below.
The reconstituted plant pieces were subjected to the same Buroma cut test as the reconstituted plant pieces of example 1.
The loss of dust was 4.9%, very low.
The obtained reconstituted plant pieces are then chopped so as to be smokeable without burning. The sensory properties of the resulting aerosol are satisfactory to the user.
