Analysis of amino acids composition in different fruit parts of two muskmelon varieties
In order to explore the composition and content of amino acids in muskmelon in Xinjiang,and deeply explore the nutritional value and utilization potential of muskmelon in Xinjiang,the mature fruits of YG and QLG were used as materials,and gas chromatography-mass spectrometry(GC-MS)was employed to analyze the composition and content of amino acids in flesh and peel. The results showed that a total of 37 amino acids were detected in two melon varieties,of which 18 were protein amino acids. The total amino acids content of protein in the peel of two melon varieties were signif-icantly higher than those in the flesh,while the content of flavor,sweet and sour amino acids in the flesh were significantly higher than those in the peel. Glutamine is the protein amino acid with the highest content in peel,alanine is the protein amino acid with the highest content in flesh,and γ-aminobutyric acid(GABA)is the non-protein amino acid with the high-est content in all parts of the two varieties. The results of pairwise comparison of different parts of the two melon varieties showed that there were 9 common different amino acids among the comparison groups. The research results provide refer-ence for the study of amino acids and ester aromatic substances in muskmelon fruits,and also provide materials and basis for the comprehensive development of muskmelon fruits in Xinjiang.
