Abstract: The quality of beef with different ultimate pH is significantly different. Beef with high ultimate pH is dark, firm and dry and easily spoils, while beef with intermediate ultimate pH (5.8–6.2) has poor tenderness. This paper summarizes the differences in the quality and safety of beef with different ultimate pH in terms of tenderness, water-holding and microbiology, as well as the potential mechanisms causing these differences. It aims to provide useful ideas and theoretical guidance for researchers interested in finding ways to improve the quality of beef with different ultimate pH and more broadly to reduce the economic loss of the beef industry.

Key words: beef, ultimate pH, color, tenderness, spoilage
