|Abstract:||Feed additives need to be authorised to be placed on the market according to Regulation (EU) No 1831/2003. Next to laying down the procedural requirements the Regulation creates the European Union Reference Laboratory for Feed Additives (EURL-FA) and requires applicants to send samples to the EURL-FA. Once authorised the characteristics of the marketed feed additives should correspond to those deposited in the sample bank of the EURL-FA. For this purpose the submitted samples were subjected to near infrared (NIR) and Raman spectroscopy for spectral characterisation. These techniques have the valuable potential of characterising the feed additives in a non-destructive manner without any complicated sample preparation. This paper describes the capability of spectroscopy for a rapid characterisation of products to establish whether specific authorisation criteria are met. The study presented in this paper is based on the analysis of feed additive samples from different categories and functional groups, namely products containing (1) selenium (2) zinc and manganese, (3) vitamins, and (4) essential oils such as oregano and thyme oil. The use of chemometrics turned out to be crucial, especially in cases where the differentiation of spectra by visual inspection was very difficult.|
