The study of the qualitative composition of the muscle tissue of animals is necessary in connection with the influence of the nutrient content on the technological, taste and dietary properties of meat. The major known changes in the biochemical parameters of the animal tissues are in the content of amino acids and fatty acids, etc. The aim of the work was to compare different chromatographic methods and to identify the most effective of them for the determination of fatty acids and amino acids in pig meat. The following HPLC methods are known for analyzing food products: ultra-HPLC, «hydrophilic» chromatography, two-dimensional and multidimensional HPLC methods, chiral chromatography, express chromatography, capillary HPLC, nano-HPLC, micellar HPLC, HPLC on monolithic columns, HPLC on surface porous sorbents, immunochromatographic methods, green chromatography, high-temperature HPLC. The most common methods for the determination of amino acids and fatty acids are reversed-phase and cation-exchange HPLC.

Ruhemann’S Purple

An improved ninhydrin–hydrindantin reagent has been developed for the quantitative determination of amino acids and peptides separated on filter paper chromatograms. This represents a modification of a reagent described earlier, which was based in turn upon the well-known solution of Moore and Stein. The present reagent has been in use for several years and has shown the advantages of high stability, extremely low and steady reagent blank values, and approximately stoichiometric yields of Ruhemann's purple for most amino acids. In addition to its use for determinations on excised areas from filter paper chromatograms, conditions are defined for the use of the reagent for determinations of amino acids in solutions.
