失水率/系水力在TA1质构仪中的实现。质构仪TA1中国区银飞电子有销售。TA1质构分析仪在测试食品测试、宠物食品测试、化妆品测试和药物测试中的压缩力、剪切力、挤压力、穿刺力、硬度等方面表现出色。对于较大的试样，质构分析仪有一个180 mm（7.08 in）喉深的大工作区域，以及一个灵活的工作台。该试验机可对高达102kgf（1kN/225 lbf）的应用进行快速、详细的质构轮廓分析（TPA）。

它内置测试软件以提高性能，TA1质构分析仪可与NEXYGENPlus数据分析软件配合使用。NEXYGENPlus软件与Excel和Word交互，使您能够自动将测试结果直接传输到自己的公司模板中。TA1质构分析仪的负载精度为传感器值的正负0.5%至1%，提供了高动态范围，从而减少了覆盖整个力范围所需的传感器数量。
It can test the water loss rate of meat, and then get the water power, judge the water retention of meat and affect the storage of meat, and provide favorable data for the sensory quality research of meat products. The moisture content of meat samples measured by drying method is calculated by water content, and the moisture loss can be calculated automatically by texture analyzer TA1。
The Benefits of Texture Analysis Texture analysis can highlight quality improvement opportunities throughout the supply chain and the production process. New or alternative ingredients can be compared with existing ingredients. In production, texture analysis is used for the measurement and control of process variations such as temperature, humidity and cooking time. A texture profile analysis test replicates the effect of two bites on a sample. Lloyd Instruments NEXYGENPlus texture analysis software captures force, distance and time during the test, allowing the calculation of texture critical parameters such as: Adhesion Force Firmness Modulus Adhesiveness Fracturability Resilience Chewiness Gumminess Springiness Cohesiveness Hardness Stringiness.

失水率测试步骤如下(references):

 

● take 250g of meat sample (the longest muscle in the back, 2-3H after slaughter), use a circular sampler with a diameter of 2.532cm (area of about 5cm2), cut a sample of eye muscle in the center, with a thickness of 1cm, called mass, and the data will be uploaded to TA1 system automatically;

 

● it is placed on the pressure gauge platform with qualitative medium speed filter paper with good multi-layer water absorption. The water content is impervious and all the water is absorbed. The quality difference before and after pressure is the weight loss of meat sample;

 

● cover the meat sample with multi-layer qualitative medium speed filter paper, add a plastic plate, use a flat head cylindrical accessory with a diameter of 10cm, pressurize to 35kg, andkeep for 5min;

 

● after removing the pressure, immediately weigh the meat sample quality, and automatically upload the data to TA1 system;

 

Note: if the balance has no communication interface, it can be manually input into TA1 system and recorded automatically.
