N2 - Chia seed mucilage could be used as industrial additive due to its outstanding physical properties. However, not many reports about this gel have been published, maybe due to it remains tightly bounded to the coat seed during processing. The aim of this work was to characterise the chia seed structure and the mucilage release by microscopy, spectroscopy and image analysis techniques. Results showed that the mucilage is excreted from the polygonal cells of the epidermis coat, being composed mainly by carbohydrates fibres (18-45nm width). It was observed from the kinetic modelling that the mucilage release follows a non Fickian process (0.52=0.9984 and EDM %=0.8). Chia mucilage could be used for the controlled release of drugs, or, as a result of the size of its fibres, for the production of nanocomposites.
