Authentic Meat Detector: DNA-Level Identification for Meat Authenticity

The series of authentic meat detectors launched by Shandong Hengmei Electronic Technology Co., Ltd. integrate advanced fluorescence detection technology and precise temperature control system, with excellent detection performance and reliable operational stability. We are committed to providing strong technical support for ensuring food safety and maintaining market order through professional authentic meat detection solutions, and helping to build an honest and transparent food supply chain system.

Technical principle: Accurate identification at the DNA level

The authentic meat detector is based on real-time fluorescence quantitative PCR (polymerase chain reaction) technology, which achieves precise identification of different meat derived components through specific primers and fluorescent probes. The core technical process includes:

1.Sample pretreatment

Homogenize the meat sample to be tested

Using commercial DNA extraction kits to extract total DNA from samples

2.PCR amplification and real-time detection

Add species-specific primers, fluorescent probes, and sample DNA to the reaction system

The instrument performs precise temperature cycling (4 ℃ -99 ℃) through a semiconductor temperature control system

Real time monitoring of fluorescence signal intensity and generation of amplification curve

3.Result interpretation

Determine whether the sample contains DNA of the target species based on fluorescence signal intensity and amplification curve morphology

The detection sensitivity can reach 1 copy, with an error rate of ≤ 0.1%

This method is based on the differences in DNA sequences of different species, and can accurately distinguish various animal derived components such as pork, beef, lamb, horse meat, donkey meat, duck meat, chicken meat, etc.

Analysis of the core technological advantages of the instrument

1. Precise temperature control system

Custom Peltier module from MARLOW in the United States, with a heating and cooling rate of up to 7 ℃/s

Temperature uniformity ≤ ± 0.3 ℃, avoiding amplification efficiency differences caused by edge effects

2. Optical detection performance

13 second fast lighting technology reduces signal delay errors

Independent fluorescent channel design (FAM/HEX dual channel), crosstalk rate<0.1%

3. Intelligent operation platform

10 inch touch screen control, supporting melting curve analysis and gene typing

Built in overcurrent and over temperature protection mechanisms ensure long-term stable operation of the equipment

The authentic meat detector has elevated its ability to distinguish meat to a new level through molecular biology technology. Its high sensitivity, strong specificity, and portability make it an important tool for food supervision and enterprise quality control.
