Title: (EN) Orally administrable compositions comprising cation cross-linked polysaccharide and a polymer digestible in the lower gastrointestinal tract
Abstract: front page image
(EN)

Orally administrable compositions comprising cation cross-linked polysaccharides are provided. The compositions have the ability to mask the taste and delay the release of an active material included therein. A novel method for the preparation of the compositions is also provided. The cation cross-linked polysaccharide is preferably selected from alginic acid and demethylated pectin and the composition further comprises a digestible polymer, preferably chosen from starch, starch derivatives, α-glucans, peptides and polypeptides.
