The process of growth, development, and reproduction cannot take place in a live body without the presence of amino acids (AAs) since they are necessary for appropriate functioning. Detection of AAs in pharmaceutical and food samples is required to ensure quality, quantity, and efficacy. The AAs generally do not contain chromophores; hence their chromatographic analysis requires derivatization. The research papers published in the last few years were used to compile this manuscript. This manuscript covers various analytical, bioanalytical, and electrochemical approaches used in the identification of AAs. The analytical techniques like high‐performance liquid chromatography, ultra‐performance liquid chromatography, etc., and the hyphenated analytical techniques like liquid chromatography‐mass spectrometry, ultra‐performance liquid chromatography‐electrospray tandem mass spectrometry, and hydrophilic interaction ultra‐performance liquid chromatography are also discussed. This manuscript also briefly outlines the electrochemical analytical techniques including sensors and biosensors. This review article will be useful to the researcher working in the area of the development of analytical techniques for the detection of AAs.
