Texture of Foods and Biomaterials

需要一台质构仪万能试验机。使用所提出的设备的质地的仪器测量已被证明与消费者的饮食体验或材料的结构构象相关。质构的多维属性包括嫩度、咀嚼性、硬度、坚实度等。因此，质构在不同的研究主题中具有重要意义，如玉米粒对真菌感染的敏感性、新型聚合物的凝胶挤出、面包面团的特性、水果和蔬菜的坚实度、加工对食品质量和材料特性的影响。拟议的设备由安装在框架上以测量所施加的力的测力传感器组成。当施加力（拉伸、压缩或剪切）时，提供夹具以夹持样品。该设备的仪器允许在静态或动态操作中测量力-位移，然后用于计算纹理参数。该设备的一个令人兴奋的组成部分是先进的样品故障分析或视频和静止图像捕获格式的测试结果演示的结合。视频和/或静态图片与应力/应变数据同步，可以在测试过程中的特定点以图形显示的方式回放或显示。该功能将允许应用团队以以前不可能的方式探索纹理研究的前沿。

A texture analyzer universal testing machine is requested. Instrumental measurement of texture using the proposed equipment has been shown to correlate with either consumer's eating experience or material's structural conformation. Multidimensional attributes of texture include tenderness, chewiness, hardness, firmness, etc. Therefore, texture is of interest in varied research themes such as susceptibility of corn kernels to fungus infection, gel extrusions of new polymers, characteristics of bread dough, firmness of fruits and vegetables, effects of processing on food quality and material properties. The proposed equipment consists of load cells which are attached to a frame to measure applied force. A clam is provided to grip samples when force (tension, compression or shear) is applied. Instrumentation of the equipment allows for measurement of force - displacement in either static or dynamic operation, which is then used to compute textural parameters. An exciting component of the equipment is the incorporation of advanced sample failure analysis or presentation of test results in either video and stills picture capture format. Video and/or still pictures are synchronised with the stress/strain data and can be replayed or shown at specific points during the test in a graphical display. This feature will allow the application team to explore frontier in texture research in ways that has not been previously possible.
