[Method] Labadou underwent compression, puncture, shearing and batch compression with four probes （P/100, P/2, A/LKB-F and A/BE） and sensory evaluation was made on Labadou as per Nine Point Calibration Method. Specifical y, chewiness measured by batch compression was taken as an independent variable and hardness as a dependent variable to get a prediction model of Labadou hardness by model fitting. [Result] The ideal parameters of Labadou included probe at A/BE, test speed at 1.0 mm/s, and strain at 70%. The chewiness was of extremely significant correlation with hardness （r=0.92, P〈0.01）. [Conclusions] The detecting method could detect distinct texture of different Labadou accurately and expediently.展开更多
