Poultry represents a rich source of multiple nutrients. Refrigeration is commonly employed for poultry preservation, although extended storage duration can adversely affect the meat quality. Current research on this topic has focused on the analysis of biochemical indices in chilled goose meat, with limited information on changes in metabolites that influence the quality of the meat during storage. This study used non-targeted metabolomics and the random forest algorithm to investigate metabolite changes in goose meat over an extended storage period. The results showed a significant change in the composition of the meat as the duration of storage increased, with the identification of 121 distinct metabolites. Further analysis identified 18 metabolites that could be used as indicators of the degradation of carbohydrates, amino acids, nucleotides, and lipids. These metabolites could be used as markers to monitor the deterioration process. These intermediate metabolites tended to be transformed into lower-level products involving pyruvate, acetyl coenzyme A, and fumaric acid, used in the tricarboxylic acid cycle, performing substance transformation. This comprehensive analysis of metabolites provides a valuable reference for monitoring the freshness of goose meat, potentially improving the safety of domestic poultry products.
家禽是多种营养物质的丰富来源。虽然延长储存时间会对肉质产生不利影响，但冷藏是家禽保鲜常用的方法。目前关于这一主题的研究主要集中在对冷藏鹅肉生化指标的分析上，而关于储存过程中影响肉质的代谢物变化的信息有限。本研究采用非靶向代谢组学和随机森林算法，研究了鹅肉在延长储存期内的代谢物变化。结果表明，随着储存时间的增加，肉的成分发生了显著变化，共鉴定出121种不同的代谢物。进一步分析确定了18种代谢物，可作为碳水化合物、氨基酸、核苷酸和脂质降解的指标。这些代谢物可用作监测变质过程的标志物。这些中间代谢物倾向于转化为参与三羧酸循环的丙酮酸、乙酰辅酶A和富马酸等较低水平的产物，进行物质转化。这种对代谢物的全面分析为监测鹅肉的新鲜度提供了有价值的参考，有望提高家禽产品的安全性。
