Abstract:In order to explore the evaluation methods of the textural nature of blood tofu by mechanical index， with pig and duck blood tofu as inspection object， this paper measured sensory index and mechanical index of their texture， analyzing the mutuality between the various indicators through the analysis of the correlation be－ tween the various indicators， and further obtains prediction model of sensory indicators using regression fitting in SPSS 17.0. The results showed that： most mechanical indicators of shear mode and puncture pattern were sig－ nificantly correlated with all sensory indicators except juiciness； all the 5 sensory indexes could be fitted by the mechanical index of the regression equation. Among them， the juiciness was fitted by mechanical indicators of TPA mod， and other sensory indicators were fitted by mechanical indicators of shear mode and puncture pat－ tern， The fitting equations were respectively： Tenderness =5.266 -0.026 × Breaking force；Juiciness =12.5 -0.348× Recoverable Work Done -6.822× Cohesiveness +0.055× Chewiness；Ln（Exquisiteness）=4.572-0.529× Ln（Shearing force）+0.118Ln（1st Fracture distance for shearing force）；Ln（Springiness）=4.951-1.556×Ln（1st Fracture for breaking force）+0.349×Ln （1st Fracture for shearing force）；Ln （Overall Acceptability）=4.279-0.752×Ln（Shearing force）+0.12×Ln（1st Fracture distance for shearing force）+0.473×Ln（Breaking force）。
