Abstract：The color, taste, texture and water properties of meatballs with Zhaguangjiao and 1% to 3% of soybean protein isolate (SPI) addition were investigated by colorimeter, electronic tongue, texture analyzer and low field nuclear magnetic resonance (LF-NMR). The results showed that SPI had no significant effects on the color or water-holding capacity of meatballs (P > 0.05), while the salty and umami taste increased significantly with increasing addition of SPI (P < 0.05). Moreover, the gel structure formed between SPI and meat proteins was enhanced, thereby significantly increasing the hardness, gumminess, and chewiness of meatballs (P < 0.05). The content of bound water in meatballs increased with increasing addition of SPI. Cluster analysis and multivariate analysis of variance indicated that addition of SPI at 1% could significantly improve the quality of meatballs (P < 0.001). Thus, we concluded that soybean protein isolate has a great potential for application in the processing of Zhaguangjiao meatballs.
