Abstract Tenderness is one of the most important quality indexes of meat products. Meat tenderness is affected by many pre-and post-slaughter factors. Heat shock proteins (HSPs) are highly conserved proteins produced by the body in response to stress. They are classified into many types and have various biological functions such as acting as molecular chaperones. Recent studies have shown that HSPs can regulate meat tenderness during postmortem aging by inhibiting myofibrillar protein degradation, modulating cell apoptosis and affecting protease activity. In this paper, the correlation between HSPs and meat tenderness is reviewed, aiming to provide a reference for further studies to understand the mechanism behind the influence of HSPs on meat tenderness, improve meat quality and develop new processing technologies.
