Randomized trial develops a six-plex PCR method to identify yak meat and its adulterants, indicating high specificity and sensitivity.

The main aim is to create a reliable method for identifying yak meat and its common adulterants to ensure food authenticity.
Established a six-plex PCR assay for simultaneous identification of yak meat and five adulterants.
Systematically optimized annealing temperature and primer concentrations for better performance.
Analyzed five yak meat products from online retailers for adulteration detection.
The assay detected adulteration with 1% of any adulterant meat with good repeatability.
Adulteration was confirmed in several samples, including beef, pork, and donkey meat.
The method demonstrated excellent specificity, successfully distinguishing the target species.
