The rapid development of metabolomics technology has provided a powerful tool and new research perspectives for in-depth study on pork quality traits, which is crucial for in-depth understanding of the formation mechanism of pork quality traits, improving pork quality, and promoting the development of the meat industry. This article reviews the concepts related to metabolomics technology, summarizes the analysis strategies suitable for different research purposes, and briefly introduces the main separation and detection techniques in metabolomics. Meanwhile, a systematic review of recent research on pork quality using metabolomics technology is provided, summarizing the analysis routes and research results of various traits including slaughter meat quality (including pH, meat color, water-holding capacity, intramuscular fat), edible quality (including flavor, processing methods), additional quality (including freshness, storage methods, spoilage contamination), and meat quality identification (including meat adulteration, breed identification, feeding conditions). The review reveals the application value of metabolomics in the study of pork quality traits, providing a certain reference for pig breeding and the discovery of key markers related to pork quality.
