| 摘 要： | 利用质构仪对薯片硬度、脆度进行断裂试验,同时收集断裂声信号进行对比分析,建立薯片酥脆度与声学特征之间的关系,对其进行物理性质的声学评级。针对3种不同薯片产品的硬度、脆度及韧性,与其断裂声音特性之间的关系进行相关性分析。结果表明:薯片脆性越大,硬度越小,韧性越小,断裂声声压级越大,但不呈线性相关。

| Abstract: | The hardness and crispness of potato chips were tested by texture analyzer in the present study. Moreover, the fractured acoustic signals were collected to analyze the relationship between the crispness of potato chips and the acoustic characteristics, and the acoustic rating of physical properties were evaluated. The relationship between the hardness crispness and flexibility of three different potato chips and their acoustic characteristics were investigated. The results showed that the more crispness of potato chips had, their hardness and toughness were lower, and the sound of breaking was louder. However, no significant linear correlation were found between the characteristics. |
