The preservation period is one of the apparent factors affecting egg quality. Previous studies based on traditional detection techniques demonstrated that storage period would significantly influence egg weight, eggshell weight, albumen height, haugh unit (HU) and albumen viscosity. Herein, we employed non\u2010targeted metabolome technology to reveal the comprehensive changes in metabolite composition in duck eggs under the impacts of storage period.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The results showed that the primary metabolites in the yolk of duck eggs are amino acids, carbohydrates and lipids. In contrast, the primary metabolites in the albumen are amino acids, benzene and indoles. We screened 43 and 16 different metabolites, respectively, in the albumen and yolk of duck eggs with different preservation periods. In addition, kyoto encyclopedia of genes and genomes (KEGG) enrichment was performed, and the results showed that various nutrients were degraded in the egg after preservation, thus affecting the quality of duck eggs. These nutrients included amino acids, fatty acids, nucleotides, sugars and vitamins; meanwhile, ammonia, biogenic amines and some flavor substances were produced, affecting the quality of the eggs.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Ourfindings can contribute to a holistic understanding of metabolite composition changes in duck eggs during
