  abstract = {{R}ecent scandals in the agro-food industry highlight the necessity of increasing meat and food traceability to determine animal origin. {T}his article presents two matrix-assisted laser desorption ionization time-of-flight mass spectrometry ({MALDI}-{TOF}-{MS}) methods that do not require complicated sample preparation. {T}he first method concerns the determination of the origin of meat (pork, beef, horse, veal and chicken) from raw and processed meat used in culinary preparations. {S}amples were prepared in order to extract proteins, then analyzed with a linear {MALDI}-{TOF}-{MS} system. {M}ass spectra were computed by cluster analysis using {B}ruker {B}iotyper software. {S}amples representing different meat origins were efficiently separated into distinct mass spectra clusters. {T}he second method concerns the determination of the origin of gelatin (pork or beef) in food preparations and galenic formulations. {H}ere, gelatin was digested into peptides, themselves analyzed using a reflectron {MALDI}-{TOF}-{MS} system. {M}ass spectra enabled us to detect and distinguish pork from bovine gelatin, based on specific peak patterns. {W}e were able to detect down to 1% of gelatin in spiked candies and detect down to 20% of pork-gelatin in beef gelatin. {B}oth techniques have potential for the systematic and routine traceability of meat and collagen.},
