Meat authenticity rapid identifier

Brief introduction:

The real and fake meat detector is an efficient and convenient food testing equipment designed for identifying the authenticity of meat. It can detect various animal-derived ingredients such as pork, beef, mutton, horse meat, donkey meat, duck meat, chicken, etc. It can quickly and accurately detect the DNA components in meat and meat-derived samples to ensure that the consumed meat is authentic and reliable. Its high sensitivity and low error rate ensure the accuracy of the test results and provide professional testing services for various testing units.

Working principle:

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

The following are its detailed working steps:

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

2. PCR reaction: add specific primers, probes and sample DNA to the reaction tube and place it in the detector for PCR amplification.

3. Real-time detection: During the PCR amplification process, the instrument monitors the DNA amplification in real time through fluorescent signals to generate an amplification curve.

4. Data analysis: According to the fluorescence signal intensity and amplification curve, determine whether the sample contains a specific DNA sequence, so as to determine the authenticity of the meat.
