Abstract:This paper provides a systematic review of the mechanism by which fat influences the flavor of meat and the regulatory pathways involved. During meat cooking, lipid oxidation and its interaction with the Maillard reaction produce a range of volatile organic compounds, which are key contributors to meat flavor. This article outlines the factors that affect meat flavor, including fatty acid composition, processing methods, and storage conditions. It also introduces the various techniques for detecting meat flavor, such as mass spectrometry, lipidomics, and electronic nose. Finally, the review summarizes the strategies for improving meat flavor, aiming to provide theoretical support for enhancing meat quality.
