The composition, functional properties and structural features of the fiber from Rosa rubiginosa defatted seeds and from Gevuina avellana defatted and partially deproteinized seeds were evaluated. The effect of phosphate salts and temperature during the extraction of fibres and the influence of two drying technologies on the distribution of soluble and insoluble dietary fibre were assessed. The extraction of protein and monosaccharides was favoured by increasing temperature in the range studied. Water and oil absorption capacities higher than 10 g g-1 were observed for soluble and insoluble fibres from Gevuina avellana and for the soluble ones from Rosa rubiginosa. The insoluble fibre product from Rosa and Gevuina contained 650-810 g kg-1 and 390-440 g kg-1 neutral detergent fibre respectively. The protein content in the insoluble fibre varied in the range 100-150 g kg-1 and 120-260 g kg-1 and in the soluble fibre between 200-550 g kg-1 and 180-370 g kg-1 for Rosa and Gevuina respectively.
