AI Technical Summary
Existing meat tenderness test samplers have problems such as slow sampling speed, inconsistent samples, expensive equipment and difficulty in carrying, and the plug-in cutting method will disrupt the fiber distribution and affect the test results.
A sampler consisting of a transparent plastic storage tube, a rubber sleeve and a rubber handle was designed. The sampling knife cuts along the storage tube to form a meat sample with a diameter of 1.27 cm and a length of 2.8 cm, avoiding instantaneous vertical pressure. Transparent plastic and rubber materials are used to reduce cost and volume.
It achieves accurate and rapid meat tenderness testing, reduces costs, improves portability and safety, and ensures sampling consistency and accuracy of test results.

Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of food samplers, and in particular to a sampler for testing the tenderness of livestock and poultry meat. Background Technology
[0002] Meat tenderness determination is a crucial part of livestock and poultry meat quality testing. The current agricultural standard NY / T 1180-2006 clearly states that meat tenderness is reflected by the peak shear force in a shear force test. This process requires obtaining a cylindrical sample with a diameter of 1.27 cm and a height of at least 2.5 cm from a meat sample that has undergone a certain degree of cooking, and then cutting it perpendicular to the cylinder. However, it is worth noting that: firstly, in practice, manual sampling is slow and yields samples of varying diameters, increasing test variability; secondly, commercially available samplers are expensive, bulky, and difficult to carry, and some plug-and-play cutters generate significant instantaneous pressure during contact with the meat sample, disrupting fiber distribution patterns and affecting test results. Utility Model Content
[0003] This invention provides a sampler for testing the tenderness of livestock and poultry meat, which is accurate, fast, low-cost, portable, and safe.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A sampler for testing the tenderness of livestock and poultry meat includes a receiving tube with a stabilizing support at its upper part and a rubber sleeve at its lower part. A receiving groove is formed on the upper wall of the receiving tube between the bottom of the stabilizing support and the upper part of the rubber sleeve, and a circumferentially shaped groove is formed on the lower wall, terminating at the circumferential end point, forming an unclosed state. The receiving groove and the circumferential groove are connected by a groove on the wall of the receiving tube. The sampling knife has a rubber handle that is attached to the receiving point.
[0006] The stabilizing support and storage tube are made of transparent plastic.
[0007] Compared with the prior art, the present invention has the following beneficial effects;
[0008] 1. Ensure the accuracy of each sampling and reduce the variability in shear force testing. Inside the receiving tube of the livestock and poultry meat tenderness test sampler, the sampling blade starts from the receiving point, circles around the hollowed-out part of the receiving tube, and finally forms an approximate circle with a diameter of 1.27 cm at the end of the ring cut. The length of the sampling blade ensures that the height of the sampled meat column is 2.8 cm. That is, the meat sample with a diameter of 1.27 cm and a height of 2.8 cm is accurately obtained through ring cutting. At the same time, the sampling blade along the cutting path will not generate huge vertical pressure in an instant, which will disrupt the fiber distribution.
[0009] 2. The sampling speed has been improved. The cutting path of the sampling knife is fixed by the constraint of the rubber handle and the fitting of its own structure into the hollowed-out part of the storage tube. This improves both accuracy and sampling efficiency, enabling rapid sampling.
[0010] 3. Low cost, easy to carry, and safe. The main structure of this utility model consists of a stable support and storage tube made of transparent plastic, a rubber sleeve and handle made of rubber, and a stainless steel sampling knife. Compared with some pure steel sampling instruments, it is less expensive and smaller in size. The sampling knife and storage point can be stored together, making it easy to carry. The transparent plastic allows for better observation of the sampling knife in the storage tube, and it is safe.
[0011] This invention guarantees that the actual sampling task will be completed in accordance with current agricultural standards. Attached Figure Description

[0013] Figure 2 for Figure 1 A cross-sectional view of the structure (in the state of the sampling knife cutting). Detailed Implementation
[0014] The present invention will now be described in further detail with reference to the accompanying drawings.
[0015] Reference Figure 1 , Figure 2 A sampler for testing the tenderness of livestock and poultry meat includes a receiving tube 2, a stabilizing support 1 installed on the upper part of the receiving tube 2, and a rubber sleeve 3 installed on the lower part of the receiving tube 2; a receiving groove 6 is opened on the upper wall of the receiving tube 2 between the bottom of the stabilizing support 1 and the upper part of the rubber sleeve 3, and a circumferential groove is opened on the lower wall, which terminates at the circumferential end point 7, forming an unclosed state; the receiving groove 6 and the circumferential groove are connected by a groove opened on the wall of the receiving tube; the sampling knife 5 is provided with a rubber handle 4, which is hooked at the receiving groove 6.
[0016] The stabilizing support 1 and the storage tube 2 are made of transparent plastic.
[0017] The working process of this utility model:
[0018] According to NY1180-2006, take meat samples with a core temperature of 0~4℃, place them in a 1500W constant temperature water bath at 80℃, and remove them when the core temperature reaches 70℃. Place them on a cutting board for cutting.
[0019] Holding the stabilizing holder 1, place the sampler on the meat sample and stabilize it with the rubber sleeve 3. Note that the sampler should be parallel to the muscle fiber direction, and the meat sample thickness should be less than 2.8 cm. Holding the stabilizing holder 1 in one hand and the rubber handle 4 in the other, start from the collection point 6 and move the sampler upwards, horizontally, and downwards along the path of the collection tube 2 to pierce the meat sample. The sampling knife 5 should be parallel to the meat sample fibers to avoid creating a vertical force that could damage the fibers. Continue along the path until the circumferential cutting endpoint 7. At this point, a small portion will remain uncut. Holding the stabilizing holder 1 and the rubber handle 4, make a slight clockwise rotation using the center of the rubber sleeve 3 as a reference point to complete the remaining cut. Then remove the sampler to obtain the meat sample for tenderness testing. After sampling, return the sampling knife 5 from the circumferential cutting endpoint 7 back to the collection point 6 along the cutting path to complete the collection.
