What is the measurement principle of meat tenderness?

ST-16A meat tenderness tester is a special instrument for meat tenderness determination, designed and manufactured in strict accordance with the standard NY/T 1180-2006 "Determination of Meat Tenderness - Shear Force Method". It can simulate the chewing action of human teeth on muscles and various foods to measure the shear value of muscle and food samples, and can also determine the tenderness, hardness and other physical parameters of fruits, vegetables, flour products and other foods, providing direct data for meat quality analysis and livestock breeding. It is an ideal testing equipment for food manufacturers, quality inspection, commodity inspection, universities, scientific research and other departments.

Measuring principle: Tenderness refers to the shear force required when cutting meat. Shear force is the force used by the tool of the testing instrument to cut the tested meat sample. The instrument's sensor records the force applied when the tool cuts the meat sample, and takes the peak shear force (maximum force) as the tenderness value of the meat sample.

Main technical parameters:

- Measuring range: (0~250) N
- Resolution: 0.01N
- Indication accuracy: <±1%
- Shear speed: 1-1000mm/min (stepless speed regulation)
- Circular drilling sampler: 1.27cm in diameter
- Tool thickness: 3.0mm±0.2mm
- Edge inner angle: 60°
- Height of inner triangular notch: ≥35mm
- Anvil mouth width: 4.0mm±0.2mm
- Voltage: 220V 50Hz

ST-16A meat tenderness tester adopts a 7-inch touch screen display, high-performance stepper motor and precision ball screw drive to ensure accurate transmission. It can automatically complete the test, display the curve automatically, has the function of test data statistical processing, and is equipped with a micro printer for output. It is equipped with a standard sampler (￠12.7mm) for muscles or food, and supports unit switching between N and kg. The displacement distance is 1-300mm, and the force value, displacement and force-displacement curve are displayed in real time during the test.
