Texture of Foods and Biomaterials

需要一台纹理分析仪万能试验机。使用所建议的设备对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型相关。质地的多维属性包括嫩度、咀嚼性、硬度、坚固性等。因此，质地对各种研究主题感兴趣，如玉米粒对真菌感染的敏感性、新聚合物的凝胶挤压、面包面团的特性、水果和蔬菜的硬度、加工对食品质量和材料特性的影响。该设备由安装在框架上的测力元件组成，用于测量外力。当施加力(拉力、压力力或剪力)时，提供一个钳子来抓取样品。该设备的仪器允许在静态或动态操作中测量力-位移，然后将其用于计算纹理参数。该设备的一个令人兴奋的组成部分是结合了先进的样品故障分析或以视频和静止图像捕获格式呈现测试结果。视频和/或静止图像与应力/应变数据同步，并且可以在测试期间的特定点以图形显示的方式重放或显示。这一功能将允许应用程序团队以前所未有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.
