剪切实验测试梨果肉质地研究

Study on pear's texture by WBS test.

用TA-XT2i质地分析仪通过剪切实验这种大变形方法对货架期间梨果肉质地进行监控,结果表明,在货架期间梨果肉各质地参数均呈下降趋势,各质地参数之间具有很高的相关性和相同的变化趋势,因此可以用其中任一指标来反映复杂的质地。另外,利用剪切曲线能很好的表征梨的脆性。

The WBS test on “Dangshan pear” during shelf life by TA-XT2i through destructive method shows that the parameters such as hardness, brittleness, elasticity, chewing, resilience, and cohesiveness of the fresh pear, share the same descending trend, so any index can reflect the complicated texture, Crispness of pear could be depicted by WBS shear curves.
