Authentic Meat Detector: An efficient and convenient food testing device designed specifically to identify the authenticity of meat

1、 Brief introduction:

Meat source detection instrument is an efficient and convenient food testing device designed specifically for identifying the authenticity of meat. It can detect various animal derived ingredients such as pork, beef, lamb, horse meat, donkey meat, duck meat, chicken meat, etc. Can quickly and accurately detect DNA components in meat and meat derived samples, ensuring the authenticity and reliability of the meat consumed. Its high sensitivity and low error rate ensure the accuracy of the detection results, providing professional detection services for various testing units.

2、 Working principle:

The real and fake meat detector uses real-time fluorescence quantitative PCR technology to detect and amplify DNA in meat samples using specific primers and probes.

The following are its detailed work steps:

1. Sample preparation: Homogenize the meat sample and extract DNA.

2. PCR reaction: Specific primers, probes, and sample DNA are added to the reaction tube and placed in a detector for PCR amplification.

3. Real time detection: During the PCR amplification process, the instrument monitors the DNA amplification status in real time through fluorescence signals and generates amplification curves.

4. Data analysis: Based on the fluorescence signal intensity and amplification curve, determine whether the sample contains specific DNA sequences to determine the authenticity of meat.
