Specie determinazione e la quantificazione in miscele Utilizzando MRM Spettrometria di massa dei peptidi applicata per l'autenticazione a base di carne

We present a protocol for identifying and quantifying the components in mixtures of species possessing similar proteins. Mass spectrometry detects peptides for identification, and gives relative quantitation by ratios of peak areas. As a tool food for fraud detection, the method can detect 1% horse in beef.
