DNA is a universal molecule that has unequivocal traits for every living organism, so it allows a unique characterization. DNA can be recovered from many biological materials and DNA-based techniques often enable the identification of samples regardless of the processing undergone. For this reason, they are the most important analytical tools for food authenticity.

Among the NGS methods, DNA Metabarcoding has emerged and it allows for the massive sequencing of genetic markers that provide taxonomic information on the species.

DNA Metabarcoding Application

Vegetable species
Animal species
Microbial species
