Effect of aqueous ethanol washing on functional properties of sunflower materials for meat analogue application

Sunflower kernel is rich in protein and considered an alternative plant source for meat analogue application. The effect of process conditions used to make ingredients from sunflower needs be investigated on the functional structuring properties. Pre-pressing de-oiling with 96% ethanol were applied obtain de-oiled (DSK). Pressed (PSK) was obtained by more intensive pressing only. Their concentrates aqueous washing study oil phenol removal. DSK its concentrate formed a fibrous product at 40 wt% shearing heating 140 ? shear cell. washed led stronger products upon heating. However, PSK, before after only crumble gel under same conditions. differences water holding capacity, nitrogen solubility index, rheological properties remarkably small between concentrates. remaining material crucial potential, while content does not seem have relevant influence. primary turned out determining factor further removal washing.
