PROCESS FOR THE SHAPING OF ALKALINE (EARTH) METAL BENZOATE PARTICLES
The invention relates to a process for the shaping of alkaline (earth) metal benzoate particles in which the particles make a spinning motion. Preferably, alkaline metal benzoate extrudate containing 5-40 wt.% water is introduced into a spheronizer so that the cylindrical rods obtained via extrusion...

| description | The invention relates to a process for the shaping of alkaline (earth) metal benzoate particles in which the particles make a spinning motion. Preferably, alkaline metal benzoate extrudate containing 5-40 wt.% water is introduced into a spheronizer so that the cylindrical rods obtained via extrusion are transformed into spherical particles by a spinning motion. As such, particles are obtained that have a smearability that is strongly reduced compared with that of the particles before spheronizing, for instance a smearability that is lower than 50 %, preferably lower than 40 %. Other mechanical properties, such as crushability, bulk density and harness, are also significantly improved. Benzoates are often used as preservatives in foodstuffs, such as for instance soft drinks. |
