Correlation between Texture and Sensory Evaluation of Labadou

腊八豆质构与感官评价相关性的研究(英文)

[Objective] The aim was to measure hardness and chewiness of Labadou with a texture analyzer and explore correlation of hardness and chewiness with quality by sensory evaluation. [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.

[目的]利用质构仪测定腊八豆的硬度和咀嚼性,并研究其与感官品质的相关性。[方法]采用P/100、P/2、A/LKB-F和A/BE等四种探头分别对腊八豆进行下压、穿刺、剪切和批量压缩试验。利用打分法中的九点标定法对腊八豆进行感官评价。以批量压缩测试指标咀嚼性为自变量,感官评价指标硬度为因变量,进行模型拟合,得到了腊八豆的感官硬度预测模型。[结果]腊八豆的理想测试参数为探头A/BE,测试速度1.0 mm/s,压缩量为70%,其咀嚼性与感官评价硬度之间存在极显著相关性(r=0.92,P<0.01)。[结论]使用质构仪测定可以客观地反映腊八豆产品硬度和咀嚼性等质构特性的变化。
