Completely-soluble solid particle(s) based on dietary fibre(s)
A completely-water-soluble solid particle is based on at least one aroma and a support comprising water-soluble dietary fibers. The particle has a hardness of at least 0.2 GPa.
1. Method for producing completely-water-soluble solid particles that include at least one hydrophobic aroma on a support that consists of water-soluble dietary fibres, said method comprising:
preparing a mixture of powdered water-soluble dietary fibres selected from the group consisting of inulin, oligofructoses, and mixtures thereof and said hydrophobic aroma in the absence of a hydrophilic solvent or water under conditions effective to obtain a semi-solid mass that consists essentially of said dietary fibres and said hydrophobic aroma,
extruding the semi-solid mass through a die to form filaments,
cooling the filaments, and
calibrating the filaments to obtain solid particles of a desired size, wherein the particles have a hardness of at least 0.2 GPa.
2. Method according to claim 1 wherein when the hydrophobic aroma is in solid form, the hydrophobic aroma is incorporated as such in the mass, or is dissolved or dispersed in a hydrophobic solvent.
3. Method according to claim 2 , wherein the hydrophobic solvent is selected from the group consisting of triacetin, vegetable oils, and mineral oils.
4. Method according to claim 1 , wherein an initially hydrophilic aroma is incorporated in the mass after having been made hydrophobic.
5. Method according to claim 1 , wherein hydrophobic aroma is in a liquid form.
6. Method according to claim 1 , wherein said extruding is carried out at a temperature of about 30-130° C.
7. Method according to claim 1 , wherein said conditions effective to obtain a semi-solid mass comprise a temperature of about 35° C.
