| 摘 要： | 不同极限pH值的牛肉品质差异明显，高极限pH值的牛肉表面发黑、发暗，且易于腐败，中间型极限pH值（5.8～6.2）的牛肉嫩度低。因此，本文主要从牛肉颜色、嫩度、保水性和微生物4 个方面综述不同极限pH值下牛肉食用品质和安全品质的差异及机制，旨在为探寻改善不同极限pH值牛肉品质的方法提供科研思路和理论指导，以降低牛肉产业的经济损失。

| 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. |
