Low bulk density composition for making a tea beverage having reduced dust or fines
The present disclosure relates to an infusion product for making a beverage, such as a tea or tea-like drink. In order to produce the composition of the present disclosure, plant materials are contacted with a solvent to remove an extract. The remaining plant materials are then formed into a fibrous structure or network, such as a sheet or fibrous layer. The extract may be further treated or concentrated and then reapplied to the plant materials. In accordance with the present disclosure, the resulting sheet or layer is then reduced to discrete pieces having a unique particle size distribution. Through the process of the present disclosure, a composition is produced that not only has a minimal amount of fines and dust, but can also have a relatively low bulk density.
1. A composition configured to produce a beverage or broth by soaking the composition in a liquid, the composition comprising:
a fibrous structured matrix material formed from insoluble residue of plant materials contained in a porous container, and
wherein the fibrous structured matrix material has been treated with a plant extract, and
the plant material comprising materials obtained from a tea plant, an herbal tea plant, a fruit, a vegetable, a spice, or mixtures thereof, the composition being in the form of discrete pieces of the fibrous structured matrix material, the discrete pieces have a particle size distribution such that when the composition is subjected to a sieve test using a RETSCH sieve shaker AS200, less than about 25% of the pieces pass through a sieve having a square mesh size of 1 mm, less than about 1% of the pieces pass through a sieve having a square mesh size of 0.5 mm, and wherein greater than about 50% of the pieces fail to pass through a sieve having a square mesh size of 2 mm, wherein the composition has a bulk density of less than about 0.2 g/cm 3 .
2. The composition as defined in claim 1 , wherein the plant material contained in the composition comprise materials obtained from a tea plant and wherein less than 10% of the pieces pass through a sieve having a square mesh size of 1 mm and wherein greater than about 60% of the pieces fail to pass through a sieve having a square mesh size of 2 mm.
3. The composition as defined in claim 1 , wherein the fibrous structured matrix material is formed from insoluble residue of plant materials comprising a black tea blend, white tea blend, yellow tea blend, oolong tea blend, pu-erh tea blend, or mixtures thereof.
4. The composition as defined in claim 1 , wherein the fibrous structured matrix material is formed from insoluble residue of plant materials comprising a green tea blend.
5. The composition as defined in claim 1 , wherein the fibrous structured matrix material is formed from insoluble residue of plant materials comprising a rooibos tea blend.
6. The composition as defined in claim 1 , wherein the discrete pieces have a particle size distribution such that less than about 0.8% of the pieces pass through a sieve having a square mesh size of 0.5 mm.
7. The composition as defined in claim 4 , wherein the discrete pieces have a particle size distribution such that less than about 5% of the pieces pass through a sieve having a square mesh size of 1 mm.
8. The composition according to claim 1 , wherein the fibrous structured matrix material formed from insoluble residue of plant materials comprises a blend of different plants.
9. The composition as defined in claim 1 , wherein the fibrous structured matrix material formed from insoluble residue of plant materials and the plant extract are obtained from at least one common plant.
10. The composition as defined in claim 1 , wherein the fibrous structured matrix material formed from insoluble residue of plant materials comprises at least 70% of plant materials obtained from one plant.
11. The composition as defined in claim 1 , wherein the plant extract comprises at least 70% of a plant extract obtained from one plant.
12. The composition as defined in claim 1 , wherein at least about 70% of the plant materials used to form the structured matrix material are obtained from a tea plant or an herbal tea plant.
13. The composition as defined in claim 1 , wherein at least about 70% of the plant extract is obtained from a tea plant or an herbal tea plant.
14. The composition as defined in claim 1 , wherein the composition comprises pieces obtained from the structured matrix material combined with pieces of a natural tea blend or a natural herbal tea blend.
15. The composition as defined in claim 14 , wherein from about 20% to about 98% of the pieces contained in the composition are produced from the fibrous structured matrix material formed from insoluble residue of the plant materials.
16. The composition as defined in claim 1 , wherein the pieces contained in the composition comprise shreds obtained from the fibrous structured matrix material formed from insoluble residue of the plant materials.
17. The composition as defined in claim 1 , wherein the pieces contained in the composition are in the shape of a figure.
18. The composition as defined in claim 1 , wherein more than 50% of the discrete pieces have a length or largest dimension of from about 2 mm to about 10 mm.
19. A composition configured to produce a beverage or broth by soaking the composition in a liquid, the composition comprising:
a fibrous structured matrix material formed from insoluble residue of plant materials contained in a porous container, and
