Analysis of amino acid composition in sheep by-products by High-Performance Liquid Chromatography

https://doi.org/10.26897/2949-4710-2026-4-1-1-02

Abstract

The study aimed to investigate the amino acid composition of sheep by-products (kidney, liver, heart, spleen, blood, and lung) using High-Performance Liquid Chromatography (HPLC). The results showed that 17 amino acids in the samples were successfully detected by HPLC, and the chromatographic peak shape was sharp without interference from extraneous peaks, demonstrating good separation. The amino acid content and composition in by-products serve as key factors in evaluating protein nutritional value and directly influence this value in by-products. Among the six types of samples, there is a significant difference in the content of total amino acids; among them, liver and spleen exhibit the highest total amino acid content, 21.335 g/100 g and 19.325 g/100 g respectively, while blood exhibited the lowest value of 12.49 g/100 g.
