This review provides a comparative analysis of VOCs profiles across eight distinct meat species: beef, sheep, goat, pig, camel, donkey, horse and alpaca. It delves into the primary chemical pathways responsible for the formation of VOCs, including the Maillard reaction, lipid oxidation, Strecker degradation, and thiamine degradation, highlighting key precursors such as amino acids, reducing sugars, and lipids. Significant variations in the profiles of VOCs arise from intrinsic factors (species, breed, age, sex, and muscle type) and extrinsic factors (diets, feeding systems, post-mortem aging, processing techniques like curing, smoking, and fermentation, cooking methods, and storage conditions). The review critically evaluates the principal analytical methodologies employed for the detection and characterization of VOCs, including headspace sampling techniques (Static, Dynamic, SPME), gas chromatography–mass spectrometry (GC–MS), gas chromatography-olfactometry (GC-O), electronic noses (<em>E</em>-noses), and direct-injection mass spectrometry methods like proton-transfer-reaction mass spectrometry (PTR-MS) and gas chromatography-ion mobility spectrometry (GC-IMS), discussing their respective advantages, limitations, and applications.

The MP composite gel containing the ultrasonic SPI-SA pre-emulsion (U-SPI-SA) showed the highest gel strength (21.84 g), water-holding capacity (87.10 %), whiteness (94.20), thermal stability, shorter relaxation times, and reduced cooking loss (22.29 %). This gel also displayed greater hardness, springiness, and gumminess, as supported by the rheological measurements under various test modes. Raman spectroscopy revealed that the MP composite gel with U-SPI-SA pre-emulsion contained more β-sheet and fewer α-helix structures, resulting in a tighter and more uniform network structure and increased moisture proton density. Furthermore, intermolecular force analysis identified hydrogen bonding and disulfide bonding as the dominant interactions in the MP composite gels with different pre-emulsions. These findings support the potential of U-SPI-SA diacylglycerol pre-emulsion to improve the qualities of meat products.</div></div>","PeriodicalId":389,"journal":{"name":"Meat Science","volume":"231 ","pages":"Article 109970"},"PeriodicalIF":6.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290560","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}
