Résumé
Processed animal products (PAPs) could be a great alternative to common protein supplements and represent a good example of recycling and valorization of by-products. Due to the reintroduction of certain types of PAPs in feed, a deeper knowledge of these heterogeneous matrices is needed. Thus, the aim of this study is to evaluate the levels of essential elements and inorganic contaminants in 55 PAPs considered as potential alternatives to common protein supplements. PAPs samples were analysed for essential (cobalt, nickel, chromium, copper, zinc, iron and manganese) and non-essential elements (arsenic, cadmium, lead and mercury) by Inductively Coupled Plasma Mass Spectrometer (ICP-MS), Graphite Furnace Atomization Atomic Absorption Spectrometer (GF-AAS) and dual cell Direct Mercury Analyzer spectrometer (DMA-80). Essential elements were found with the following decreasing order iron>zinc>copper>manganese>chromium>nickel>cobalt (mg kg This study suggests that PAPs could be a useful supplement for animal diet due to their natural content of essential elements. A careful monitoring of chemical elements should be required and eventually guidelines have to be drafted for a correct use of PAPs to ensure a safe and sustainable feed production.
