Amino acids characterization of forest honeys from some area of South Sulawesi

Abstract

Amino acid characterization of forest honey was carried out in eight samples from Terasa, Mallawa and Bontojai, South Sulawesi Province. Analytical method of amino acid concentration in honey is using Ultra Performance Liquid Chromatography (UPLC). 16 amino acids with an average amino acids concentration in mg/kg dominated by histidine (589.20-2776.81), glutamic acid (992.76-1527.40), and arginine (674.10-1038.76) followed by alanine (424.84-707.41), aspartic acid (256.51-595.42), phenylalanine (200.59-711.29) and serine (419.18). Other amino acids were tyrosine (215.33-333.54), glycine (240.26-402.00), leucine (259.63-315.27), proline (209.51-333.73), threonin (217.09-279.36), valine (198.08-290.88) and lysine (157.01-275.86). Amino acids in small amounts were methionine (86.46-129.89) and isoleucine (98.24-125.94). Forest honey from Terasa, Mallawa and Bontojai can be a source of essential amino acids.
