Texture of Foods and Biomaterials

需要一种质地分析仪万能试验机。使用所提出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象相关。质地的多维属性包括柔嫩、嚼劲、硬度、紧致度等。因此，质地是各种研究主题的兴趣点，如玉米籽粒对真菌感染的敏感性，新聚合物的凝胶挤出，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性能的影响。所建议的设备由连接在框架上的测力元件组成，以测量施加的力。当施加力（拉力、压缩或剪切）时，提供一个蛤蜊来夹住样品。设备的仪表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结合了先进的样品故障分析或演示测试结果在视频和静态图片捕获格式。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方式重播或显示。这个特性将允许应用程序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.
