摘要

在炎热潮湿的气候条件下,波士腊肠牛对牛肉生产非常重要,但它们却以生产肉质较硬、变异性较大的牛肉而闻名。肌肉蛋白质在死后降解减少和延迟是这些嫩度难题的主要原因。肌肉固有的新陈代谢特性和加工条件决定了宰后新陈代谢和蛋白质降解的早期动态,从而影响后续的嫩度。骨骼肌具有多种新陈代谢和收缩特性,在不同的工作条件下,新陈代谢途径相互协调,以调节通量。考虑活体肌肉如何应对和适应细胞应激可加深我们对肌肉死亡和质量发展的理解。本综述旨在研究肌肉特性如何在死后肌肉向肉类转化的早期过程中影响新陈代谢和细胞反应,特别是它们对雏牛蛋白质分解变化的潜在贡献。

Resilience in life and death: Metabolism and proteolysis in Bos indicus muscle and meat

Bos indicus cattle are important to beef production in hot, humid climates, but they have a reputation for producing tougher beef with more variability. Reduced and delayed degradation of muscle proteins postmortem is a major reason underlying these tenderness challenges. Inherent muscle metabolic characteristics and processing conditions shape the early dynamics of postmortem metabolism and protein degradation after harvest, which impacts subsequent tenderization. Skeletal muscles exhibit diverse metabolic and contractile properties, and metabolic pathways are coordinated to regulate flux under variable working conditions. Considering how living muscles respond and adapt to cellular stress may enhance our understanding of muscle death and quality development. The aim of this review is to examine how muscle properties influence metabolism and cellular response in the context of early postmortem muscle to meat conversion, and specifically, their potential contribution to variation in proteolysis in Bos indicus beef.

期刊介绍: The aim of Meat Science is to serve as a suitable platform for the dissemination of interdisciplinary and international knowledge on all factors influencing the properties of meat. While the journal primarily focuses on the flesh of mammals, contributions related to poultry will be considered if they enhance the overall understanding of the relationship between muscle nature and meat quality post mortem. Additionally, papers on large birds (e.g., emus, ostriches) as well as wild-captured mammals and crocodiles will be welcomed.
