•Improved methods for the reliable and fast analysis of amino acids in food and feed.•Dramatic reduction of analysis time by microwave hydrolysis and UHPLC-MS/MS.•Comparable results to laboratories using ISO, AOAC and regulation (EC) 152/2009 methods.•Determination of hydroxyproline, hydroxylysine, taurine, and ornithine also possible.•High specificity and selectivity due to UHPLC-MS/MS with AQC derivatization. The determination of amino acids in food and feed by chromatography has a long history and is described in several official methods, including standards from ISO, AOAC, and the European Commission (EC) regulation 152/2009. The procedure usually consists of labor- and time-consuming preparation techniques and ion-exchange chromatography with challenging chromatographic conditions. Consequently, several approaches have been published to overcome these drawbacks but the knowledge about their suitability for complex matrices such as food and feed is limited. In this paper, we describe the development of two new methods to determine amino acids in food and feed. These methods involve microwave hydrolysis and reversed-phase UHPLC-MS/MS with pre-column derivatization using 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC). Both methods provide streamlined sample preparations and a dramatic reduction in analysis time while offering a high degree of specificity and selectivity. Selectivity also enabled the simultaneous determination of the more uncommon substances hydroxyproline, hydroxylysine, taurine, ornithine, and γ-amino butyric acid (GABA) along with amino acids typically present in food and feed. The results were all satisfactory with regards to sensitivity, accuracy, precision, and comparability with laboratories that use other methods, for example from ISO, AOAC, or regulation (EC) 152/2009. We therefore concluded that both methods provide a reliable and modern approach to overcome many of the drawbacks that occur with the conventional standard methods.
