Characterisation and evaluation of pinhão seed coat nanosuspension as a functional food source.

Araucaria angustifolia seeds from South America are culturally important; however, the seed coat is generally discarded and it has yet to find a beneficial commercial impact. Herein, we propose a new formulation for the use of the seed coat for the production of a food source. A nanosuspension was developed under two conditions, bleached and unbleached treatment.
