- Unlike the traditional culture method, this technique does not need to wait for bacteria to grow and can directly identify the presence of microorganisms through DNA.
- Among these, the most common today is PCR microbiological testing (Polymerase Chain Reaction) – DNA amplification technology that enables rapid and accurate detection of bacteria.
👉 This is exactly the foundation of modern food microbiology rapid test solutions.
Why does PCR give faster and more accurate results?
✔️ Operating principle
PCR works by:
- Extracting DNA from the sample
- Amplifying the characteristic DNA segment of the microorganism
- Detecting the presence of bacteria
👉 Even with a very small amount of bacteria, PCR can still detect it.
✔️ Outstanding advantages of PCR
- Fast: only 18–24 hours
- High accuracy: detects the correct target bacteria
- High sensitivity: detects at very low concentrations
- Fewer errors: limits false negatives
Comparing PCR with the traditional culture method

👉 It can be seen that PCR is the optimal solution for companies that need fast food microbiology testing and accurate.
