This study investigated effects of high pressure (HP) treatment of pork meat at 150 or 300MPa for 5min before manufacturing sausages on the reduction of phosphate levels and compared to sausages manufactured with untreated pork meat (control sausages). Improvement in perceived saltiness, juiciness and overall flavour was observed in sausages manufactured using HP-treated meat at 150MPa and 0% phosphate, compared to control sausages. Sausages manufactured using meat HP-treated at 150MPa and 0.25% phosphate (P<0.05) improved hardness of sausages. HP-treated meat at 300MPa and 0% phosphate decreased juiciness and adhesiveness, while at 0.25% phosphate, adversely affected emulsion stability and sensory attributes. HP treatment did not affect significantly the lightness of the sausages; however, elimination of phosphate reduced (P<0.05) the yellowness, while HP treatment at 150MPa with 0.25 or 0.5% phosphate increased (P<0.05) redness. HP reatment at 150MPa has potential for reducing phosphate levels in sausages without significant changes in their functionality and improved acceptability. •HP-treatment improved texture and overall acceptability of breakfast sausages (BS).•BS without significant changes in their functionality was obtained using HP-treatment.•HP-treatment has potential for reducing phosphate levels in BS.
