title: Effect of Black Rice Powder Levels on Quality Properties of Emulsion-type Sausage.
abstract: The effects of black rice powder on the quality of sausage were investigated. Samples were prepared with 0% (control), 1%, 3%, and 5% black rice powder. With increasing black rice powder content, the moisture and ash content of sausage increased, while protein content was significantly less than that observed for the control (p<0.05). The fat content in samples containing 5% black rice powder was significantly less than that observed for other samples (p<0.05). With increasing black rice powder content, the pH of uncooked and cooked samples increased. In addition, lightness, redness, and yellowness decreased. With increasing content of black rice powder, emulsion stability decreased. On the other hand, with increasing black rice powder content, cooking yield increased. As compared to the other samples, those containing high content of black rice powder exhibited higher viscosity. With increasing black rice powder content, the hardness of samples decreased, while the gumminess and chewiness of samples containing black rice powder were less than those observed for the control (p<0.05). Moreover, with increasing black rice powder content, the flavor, juiciness, and overall acceptability of samples increased. In addition, the tenderness of samples containing 3% and 5% black rice powder was significantly greater than that observed for the control and sample containing 1% black rice powder (p<0.05). In addition to the economic benefits, black rice powder can be used to improve quality characteristics.
