The influence of 2, 3 and 5% native starch addition instead of fat on rheological and sensory properties of finely comminuted meat products has been evaluated. The substitution of fat with potato starch in the test product resulted in the deterioration of rheological properties and sensory factors. The increasing addition of native starch, apart from the substantial decrease in fats determined by analytical methods, caused a substantial increase of thermal drip, a weakened bind of slices and an increased texture fluidity as well as weakening of such factors as: binding rate, hardness, elasticity and general texture appraisal. The sensory impression of moisture and fattiness, however, was not statistically different. The increasing addition of native starch as a fat substitute was not reflected in the sensory feeling of less impression of fattiness and more – of moisture. This confirms the good functional properties of the tested fat substitute.
