Abstract
This work aimed to determine the effects of partial and total fat substitution by inulin on the quality parameters of chicken sausages. We developed three formulations, control (F1) and two levels of inclusion of inulin, 2.5% (F2) and 5% (F3). Parameters of moisture, ash, protein, lipids, carbohydrates, pH, water activity and color (L *, a * and b *) were analyzed. The technological profile was also analyzed through the stability of the emulsion, weight loss by cooking, weight loss by exudation and shear force. The sensory attributes surveyed were color, appearance, texture, flavor, general acceptance as well as a purchase intention test. The addition of 2,5% of inulin to formulation F2 led to a reduction in water loss during cooking, weight loss by exudation as well as an increase in emulsion stability compared to other formulations. While the F3 formulation with 5% of inulin presented low-fat content, low shear strength and high levels of ash and carbohydrate compared to the control formulation. There were no changes in pH and water activity. Regarding color, the inclusion of inulin had a significant effect (p < 0.05) for the luminosity (L *) on the inner surface of the sausages. The b * value was also significant (p < 0.05) in the formulation (F3) for the inner surface and in the formulation F1 on the outer surface. The addition of inulin, especially in the formulation (F3), resulted in higher values of appearance, texture, and flavor compared to the other formulations, which reflected in the higher purchase intention. Thus, it was observed a reduction of 50% and 100% of fat with 2,5% and 5% of inulin addition without reduction of the sausages quality.
