The texture profile analysis test is an imitative test to determine texture properties of food, which quantify the consumer’s perception of eating food. The instrumental texture parameters obtained from this test depend on the specimen size and the nonstandardized test conditions. To overcome this problem, texture properties are here related to intrinsic mechanical properties, which are independent of the test conditions. Two types of materials are used to investigate the effect of viscoelasticity, plasticity and damage on the texture parameters for varying test conditions. Analytical relations between mechanical properties, test conditions, and the instrumental hardness, springiness, cohesiveness, and adhesiveness are determined. The hardness is obtained from the stiffness of the material, which is potentially rate-dependent, and the yield stress of a material in case of plasticity. The springiness is determined by the recoverable or irrecoverable strain in the material, which results from the mechanical properties in combination with the test conditions. Cohesiveness and springiness are found to be strongly related, unless structural damage is present in the material. Adhesiveness is only an indirect measure of the adhesion between the material and compression plate and depends on the test conditions and stiffness of the material. Finite element simulations reveal a decrease of hardness in case of a nonflat top surface, indicating the importance of geometrical effects.

质地轮廓分析测试是一种模拟测试，用于确定食物的质地特性，从而量化消费者对食用食物的感知。从该测试中获得的仪器质地参数取决于样品尺寸和非标准化测试条件。为了克服这个问题，纹理特性在这里与固有的机械特性有关，而固有的机械特性与测试条件无关。使用两种类型的材料来研究粘弹性，可塑性和损伤对不同测试条件下织构参数的影响。确定机械性能，测试条件与仪器硬度，弹性，内聚性和粘合性之间的分析关系。硬度是由材料的刚度获得的，材料的刚度可能与速率有关，以及在塑性情况下材料的屈服应力。弹性取决于材料的可恢复应变或不可恢复应变，这是由机械性能和测试条件共同导致的。除非材料中不存在结构损坏，否则内聚力和弹性是密切相关的。粘附力只是材料与压板之间粘附力的间接度量，并取决于测试条件和材料的刚度。有限元模拟显示了顶面不平整时硬度的降低，表明了几何效应的重要性。这是由机械性能和测试条件共同导致的。除非材料中不存在结构损坏，否则内聚力和弹性是密切相关的。粘附力只是材料与压板之间粘附力的间接度量，并取决于测试条件和材料的刚度。有限元模拟显示了顶面不平整时硬度的降低，表明了几何效应的重要性。这是由机械性能和测试条件共同导致的。除非材料中不存在结构损坏，否则内聚力和弹性是密切相关的。粘附力只是材料与压板之间粘附力的间接度量，并取决于测试条件和材料的刚度。有限元模拟显示了顶面不平整时硬度的降低，表明了几何效应的重要性。
