NIRM is a widely used technique in the field of feed analysis, which is mainly due to the rapid delivery of the results and non-destructive treatment of samples.
In the present study, JRC scientists in collaboration with a team from the Walloon Agricultural Research Centre (CRA-W) applied this technique in order to distinguish meat and bone meal (MBM) and Processed Animal Proteins (PAPs) from fishmeal even when previously treated with organic solvents. Whilst fishmeal has always been an authorised feed material, PAPs have only been recently reintroduced under restricted conditions in animal nutrition, namely for aquaculture. However, the ban of PAPs for terrestrial animals remains. Therefore, it is very important to identify e.g. the unauthorised mixing of MBM and PAPs to fishmeal and its subsequent addition to feedingstuffs for these animals. The results of the research demonstrated the fitness for purpose of the NIRM method presented in this study.
