This study aimed to investigate the possibility of replacing the isolated soy protein (ISP) as a binding agent for wheat, oat, and bamboo shoot dietary fibers. Dietary fibers and ISP were added to manufacturing process of pork emulsion, respectively, for investigate quality properties. Moisture contents of pork emulsion added wheat fiber-treated group was significantly higher than ISP-treated group (p < 0.05), and protein contents of dietary fiber-treated group were significantly lower than ISP-treated group (p < 0.05). Raw pork emulsion CIE a* value of oat, bamboo shoot fiber-treated group were significantly lower than ISP-treated group (p < 0.05). After cooking pork emulsion CIE L* value of dietary fiber-treated group were significantly higher than ISP-treated group (p < 0.05). Raw pork emulsion water holding capacity (WHC) of wheat, oat fiber-treated group were significantly higher than ISP-treated group (p < 0.05), and cooked pork emulsion WHC of wheat, bamboo shoot fiber-treated group were higher than ISP-treated group (p < 0.05). Cooking loss of ISP-treated group was significantly higher than dietary fiber-treated group (p < 0.05), and viscosity of ISP-treated group was lower than dietary fiber-treated group. Hardness of ISP-treated group was significantly lower than dietary fiber-treated group (p < 0.05); however, cohesiveness of ISP-treated group was significantly higher than dietary fiber-treated group (p < 0.05). In conclusion, dietary fiber added as binding agent to manufacturing process of pork emulsion was suitable to replacing ISP.
