Abstract: In the present invention, gelled polymeric compositions for controlled release are described, which admit the incorporation of a range of chemical, pharmaceutical or food substances, in order to be a transport towards the gastrointestinal tract. The gelled polymeric compositions as described in the invention are used as the basis for the preparation of, for example: excipients, vehicles, coatings, films, hydrogels, among others, thus being highly profitable for the development of products for the pharmaceutical industry and/or the food industry.

Abstract: The present invention provides processes that promote the solvation of calcium ions in macromolecular matrices. Processes in which the relationship, concentration, physicochemical conditions at each stage and preparation methods allow to obtain a stabilized soluble product, based on calcium salts and polymers. The present invention does not result in the deposition of crystals of the salts used, and exceeds the commercial calcium formulations so they are of great utility for their application in the food, pharmaceutical and/or cosmetic industry.
