The Spanish Interprofessional Dairy Organisation (InLac) has promoted a project with the aim of developing a technique for quantifying milk from different species in cheeses.The quantification of the percentage of milk is not a simple task and depends on several factors related to the composition of the milk, the different manufacturing processes and the degree of maturity of the cheese.

The developed PRM targeted proteomics technique has high specificity, high sensitivity, a wide dynamic range of detection and is independent of the ripening stage of the cheese sample. The method has been successfully validated for Iberian type cheeses.
