Abstract: A three-factor central composite rotatable design was adopted for studying the combined effects of flaxseed gum (FG), xanthan gum and soy protein isolate (SPI) on the productivity and textural properties of pork sausages. It was found that addition of FG, xanthan gum or SPI significantly increased the productivity of pork sausages (P<0.01) in a concentration-dependent fashion. FG and SPI had significant interactive effects on the productivity and adhesiveness of pork sausages (P<0.05). Hardness was significantly increased with increasing SPI addition (P<0.05), while increasing addition of xanthan gum or SPI caused in a gradual decrease in springiness, and there was a significant interaction between both additives (P<0.05). Cohesiveness showed a highly significant decreasing trend (P<0.01) with increasing FG addition but revealed a gradual increase with increasing addition of xanthan gum or SPI; meanwhile, a significant interaction was observed between xanthan gum and SPI (P<0.05). Chewiness was not significantly affected by FG, xanthan gum or SPI.
