SPRAY-DRIED COMPOSITIONS AND METHOD FOR THEIR PREPARATION

摘要

One object of the invention is a spray-dried composition comprising an activ e ingredient dispersed in a carrier comprising a combination of a wall-forming carbohydrate material with from 1 to 30% by weight of agar agar relative to the dried weight of the composition. The composition of the invention presen ts an advantageous behavior in an aqueous or highly moist environment wherein t he mobility of the active agent is restricted in the gelled carrier, thus preventing the release of the agent unless shear of heat are applied. Anothe r object of the invention is a process for the preparation of the spray-dried composition.
