Analysis of Amino Acids in Foods Using Automatic Pretreatment Function of Integrated HPLC

User Benefits

- Automatic pre-column derivatization method enables highly selective amino acid analysis with high sensitivity. - Proteinogenic amino acids can be analyzed within 20 minutes. - Generally used HPLC can cover all procedures for pre-column derivatized amino acid analysis.

Introduction

Foods contain many amino acids including glutamic acid, which is known to provide umami flavor. Measuring the content of each amino acid is recently used for the research activity on functional components as well as the evaluation of the nutritional value and the taste. Application News 01-01047 described automatic amino acid analysis using pre-column derivatization with the integrated HPLC that has pre-treatment function. This article introduces the amino acid analysis and real sample pretreatment protocols of 13 types of real food samples using the same method as in 01-01047.
