EINKAPSELUNG VON AKTIVSUBSTANZEN
A process for preparing free-flowing and, during handling, dust-free microparticles. The particles are at least 90% by weight, have a diameter of 100-400 mum, and contain one or more active ingredients in a glassy matrix. Generally, the process of the invention comprises the steps of (1) preparing a...

| description | A process for preparing free-flowing and, during handling, dust-free microparticles. The particles are at least 90% by weight, have a diameter of 100-400 mum, and contain one or more active ingredients in a glassy matrix. Generally, the process of the invention comprises the steps of (1) preparing an aqueous solution of the matrix materials, (2) mixing the flavor into the aqueous solution with stirring to form an emulsion or suspension, (3) spraying the emulsion in a spray drying tower under a supply of hot air to quickly create a semi-solid skin allowing outtake of moisture (water), and (4) subsequently subjecting the resulting particles to continued drying at lower temperatures in a fluid bed. |
