摘要
骨骼肌由不同类型的肌纤维构成,肌纤维的类型直接影响肌内脂肪含量、嫩度以及肉色等肉品质特性。动物出生后骨骼肌肌纤维的数量基本维持恒定,但肌纤维类型持续转化,一些外界因素如运动、营养、应激等可直接影响肌纤维类型的转化。本文针对影响肌纤维类型转化的因素及机制进行总结和分析,为今后深入研究肉品质变化机制提供参考。
Skeletal muscle consists of different types of muscle fibers which directly affect the meat quality, content of fat, meat tenderness and color.After birth, the quantity of skeletal muscle fibers keeps stable, while the types undergo constant transition.Besides, some external factors may also have some impacts on the transition such as sports, nutrition and stress.This paper summarized those factors, for reference in studying mechanism in change of the meat quality.
