Advanced analytical methods such as liquid chromatography-mass spectrometry (LC-MS) and gas chromatography–mass spectrometry (GC–MS) have now made it possible to identify plant-derived non-volatile compounds in meat. These biomarkers are crucial for authenticating pasture-fed meat to underpin stringent meat quality regulations and assurance systems, thus enhancing industry reputation and competitiveness.

Furthermore, the effect of 10 mmol/L tartrate on the myoglobin oxidation rate in beef was observed at 0.18–4.2 % oxygen. The addition of tartrate inhibited oxidation at lower concentrations but promoted oxidation at higher concentrations, with 1 % being the divergent concentration. Using tartrate, we demonstrated that myoglobin affinity is a determining factor for the oxygen concentrations that promote beef discoloration.</div></div>","PeriodicalId":389,"journal":{"name":"Meat Science","volume":"225 ","pages":"Article 109807"},"PeriodicalIF":7.1,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143610539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
