Ittiogel is a fish gelatine immediately soluble in cold water. It has the appearance of a very fine white powder. The process of raw material selection and the subsequent chemical-physical purification treatments have enabled to obtain a product of immediate solubility, which easily flocculates and gives wines a high degree of clarity. During flocculation Ittiogel incorporates and drags down all the finer particles, thus making the ensuing filtrations easier. Sedimentation is fast and the lees obtained very compact.
