DNA-based approach for species identification of goat-milk products.

ABSTRACT

Considering that mislabeled milk products have been widely reported throughout the world and that the authentication of food components is one of the key issues in food safety and quality, the aim of this study was to use DNA-based methods to investigate the prevalence of mislabeling among goat-milk products and, consequently, how far the ingredients matched the labels. The study reveals a high degree of species mislabeling in milk products (80%), underlining the need to enhance dairy traceability practices, so as to guarantee product authenticity, and provide reliable information to consumers.
