Abstract

Pectin can be used as a natural emulsifier in food formulations. In this study, textured soybean protein (TSP), used as an emulsifier in commercial sausages, was partially replaced by a mixture containing pectin and isolated soybean proteins, which were either extruded (EXT) or not extruded (MIX), and the chemical and sensory characteristics of samples were evaluated after 60 days of storage at 4 °C. Responses such as oxidation measured by PV and TBARS, hardness, color, pH and sensory characteristics were compared with those of a commercial sausage (CON). The mixture containing highly methyl-esterified pectin, textured soybean proteins and isolated soybean proteins, as emulsifier agent, reduced the hardness (EXT: 21.69±0.98 and MIX: 20.17 ±2.76 N) and the pH (EXT: 5.46±0.03 and MIX: 5.29±0.01) of the samples and increased the concentration of peroxides (EXT: 0.10±0.01 and MIX: 0.15 ±0.01 meq/kg) when compared with samples formulated only with TSP (28.57 ± 2.54 N, pH of 6.92±0.04 and PV = 0.07 ± 0.01 meq/ kg). These effects were likely caused by the anionic character of the emulsifier. However, no sensory difference was observed between the sausages containing highly methyl-esterified pectin, textured soybean proteins and isolated soybean proteins submitted to the extrusion process (EXT) and the control sausages, suggesting that the formulation proposed in this study can be a potential alternative for the further development of sausages that have functional properties or are free of artificial additives.
