Hydrocolloids are a large group of polymeric substances, which include mainly polysaccharides and some proteins. They can have different sources: natural of plant origin, animal, algae and even some, synthesized by microorganisms. They form viscous micro dispersions or gels on contact with water due to their hydrophilicity. In this way, they generate different textures, viscosity and elasticity, properties, which are used in food, pharmaceutical, the medical and research industry as a whole. Hydrocolloids can be used alone, but they are often combined with others because of their synergistic behavior in terms of their properties, which increases their usefulness.
