Researchers at the Biomedical Research Foundation of the Academy of Athens have successfully mapped the DNA of feta cheese produced throughout Greece. The study aimed to identify the genetic factors contributing to the cheese’s unique nutritional profile and characteristics. Scientists analyzed a diverse range of feta samples from various regions across the country. This genetic decoding could help standardize feta production and ensure quality control. The research provides insights into the origins and evolution of this iconic Greek product. Findings may also assist in protecting the authenticity of feta against imitations and maintaining its Protected Designation of Origin (PDO) status.
