  According to the present invention hydrocolloid compositions are provided comprising anionic polysaccharides as well as an amount of peptide material. These hydrocolloid compositions can suitably be used to gel and/or viscosify aqueous systems. Interactions between said anionic polysaccharides and said peptides in aqueous systems result in cross-linked polymer networks. According to the present invention the peptides are typically obtained by hydrolysing protein compositions and optionally subsequently isolating or purifying a cationic fraction therefrom. The use of the present gelled and/or viscosified aqueous systems in e.g. foodstuffs, beverages, encapsulates and pharmaceutical and/or cosmetic compositions are disclosed herein.

  [EN] According to the present invention hydrocolloid compositions are provided comprising anionic polysaccharides as well as an amount of peptide material. These hydrocolloid compositions can suitably be used to gel and/or viscosify aqueous systems. Interactions between said anionic polysaccharides and said peptides in aqueous systems result in cross-linked polymer networks. According to the present invention the peptides are typically obtained by hydrolysing protein compositions and optionally subsequently isolating or purifying a cationic fraction therefrom.

  [FR] L'invention concerne des compositions d'hydrocolloïdes comprenant des polysaccharides anioniques ainsi qu'une quantité définie de substance peptidique. Ces compositions d'hydrocolloïdes peuvent être utilisées de manière appropriée pour gélifier et/ou viscosifier des systèmes aqueux. Des interactions entre les polysaccharides anioniques et les peptides dans des systèmes aqueux permettent d'obtenir des réseaux polymères réticulés. Selon l'invention, les peptides sont généralement obtenus par hydrolysation de compositions de protéines, puis éventuellement par isolation ou purification d'une fraction cationique de celles-ci. L'invention concerne en outre l'utilisation des systèmes aqueux gélifiés et/ou viscosifiés dans, par exemple, des aliments, des boissons, des produits encapsulés et des compositions pharmaceutiques et/ou cosmétiques.
