Resumen:
The upgrading potential of quince (Cydonia oblonga Miller) wastes was evaluated for production of fiberrich
powders with useful functional and physiological properties. As a first approach, three products were
obtained by applying different drying conditions without or with a previous extraction either with water
or ethanol. Chemical compositions as well as physical and functional properties of the isolated fractions
were evaluated in relation to water or oil absorption for characterization. The products obtained presented
interesting hydration properties comparable to those reported for citrus and apple pulps. At the
same time, all dried fractions showed high spontaneous water absorption rate in the kinetics assay. Oil
absorption seemed to essentially depend on the microstructural characteristics of the fiber powders,
whereas parameters involving water absorption were really determined by the materials hydrophilicity.
Specific volume, which was also in part a direct function of structural differences, was associated to the
ability for oil uptake.
