The present invention is directed to a homogeneous, thermoreversible gel comprising carrageenan wherein the carrageenan has a viscosity of less than 10 cP at 75 OC when measured in a 0.10 molar aqueous sodium chloride solution containing 1.5% by weight of the carrageenan based on the weight of all components in the solution, and optionally at least one of a plasticizer, a second film former, a bulking agent, and a pH controlling agent, wherein the gel has a solids content of at least 40%. The present invention is also directed to processes for the preparation thereof, as well as to variety of products containing the gel including edible products, soft capsules, hard capsules and solid forms encapsulating powders, tablets, caplets, etc.
L'invention concerne un gel thermoréversible homogène comprenant du carraghénane. Le carraghénane présente une viscosité inférieure à 10 cP, à 75 ·C, lorsqu'il est mesuré dans une solution de chlorure de sodium aqueuse de 0,10 ; contenant 1,5 % en poids de carraghénane, en fonction du poids de tous les composants de la solution, et éventuellement, au moins un agent plastifiant, un second agent de formation de film, un agent gonflant, et un agent de contrôle de pH. Le gel présente une teneur en solides d'au moins 40 %. L'invention concerne également des procédés pour la préparation de celui-ci, ainsi qu'une variété de produits contenant ce gel, notamment des produits comestibles, des capsules molles, des capsules dures et des formes solides encapsulant des poudres, des comprimés, des comprimés-capsules, etc..
