New-type test strips accurately detect milk content in dairy products.

The Chinese Academy of Agricultural Sciences has developed a new type of test strip capable of accurately detecting the milk content in dairy products. This technology utilizes a non-nucleic acid amplification molecular hybridization method, designing probes specifically for mitochondrial DNA to achieve efficient hybridization. The method is straightforward to operate and can detect milk content as low as 1%, making it suitable for authenticating the purity of specialty dairy products such as yak milk and camel milk.

Explanation:

• Non-nucleic acid amplification: A method that detects DNA without the need for complex amplification steps.
• Molecular hybridization: A technique that uses the complementarity of DNA or RNA fragments to bind together.
• Mitochondrial DNA: DNA found within the mitochondria of cells, which is species-specific.
