Analysis of Amino Acids in Oxidized and Unoxidized Feed Samples (MA-374): Pickering Derivative
Introduction
- Commission Regulation (EC) No 152-2009 published in the Official Journal of the European Union lays down sampling and analytical methods for the official control of animal feed.
- This regulation describes analytical methods for the control of the composition of feed ingredients and compound feed products. The establishment of an amino acid profile is an important means of controlling the quality and nutritional value of animal feed.
- This regulation specifies HPLC with post-column derivatization with Ninhydrin reagent as the method for the analysis of total and free amino acids.
- The Pickering Laboratory has developed an analytical method to comply with all the chromatographic requirements of Commission Regulation (EC) No 152-2009. The same method is used for the analysis of oxidized and non-oxidized animal feed samples.
