Core Viewpoint - The Chinese Academy of Agricultural Sciences has launched an automated identification technology system for food adulteration, significantly improving the efficiency and accuracy of food safety testing [1][2]. Group 1: Technology Overview - The new technology system is based on real-time fluorescence PCR technology and features an automated DNA extraction method using magnetic beads, simplifying the testing process to three steps: sample addition, machine operation, and result reading [1]. - The automated system can analyze up to 16 indicators simultaneously, reducing the testing time from several hours to under one hour [1]. Group 2: Application and Impact - The technology covers common adulteration areas such as meat, starch, juice beverages, and traditional Chinese medicine, enabling quick identification of low-cost meat in lamb products and distinguishing between different types of milk [2]. - The system also includes a function for identifying toxic mushrooms, providing a rapid screening method for mushroom poisoning incidents [2]. Group 3: Future Developments - The team plans to optimize the technology further, establish a food source component database, and explore integration with blockchain technology for traceable and tamper-proof testing data [2]. - The goal is to eliminate deceptive practices in food sales, ensuring consumer safety and confidence in food products [2].
