Abstract

Abstract: Postmortem energy metabolism is a key biochemical pathway that affects meat tenderness, and glycolysis is the dominant process of postmortem energy metabolism, which is regulated by numerous factors. This article reviews the factors that affect the postmortem glycolysis process and the underlying mechanisms. AMP-activated protein kinase (AMPK) and sirtuin 1 (SIRT1) are important upstream regulatory factors for postmortem glycolysis. This article focuses on summarizing the effect of the AMPK/SIRT1 signaling pathway on glycolysis and postmortem endogenous enzyme systems and clarifying the underlying mechanism, in order to provide new ideas for regulating meat tenderness through the AMPK/SIRT1 signaling pathway.

Key words: energy metabolism; glycolysis; AMP-activated protein kinase; sirtuin 1; endogenous protease system; tenderness
