摘要:

肉在加热处理过程中嫩度发生了显著的变化。肉的剪切力值总体上呈现出先升后降的趋势,在0~100℃剪切力值不断上升,随着温度继续升高剪切力值开始下降,同时蒸煮损失随温度的升高而不断增加。导致这些变化的原因是加热过程中肉蛋白的热变性,其中肌原纤维蛋白和结缔组织蛋白的热变性是影响肉嫩度变化的主要因素。

关键词: 肉, 加热, 嫩度, 结缔组织, 肌原纤维蛋白

Abstract:

Meat tenderness would change significantly in thermal process. Generally, with increase of heating temperature, the shear force value increases in the range of 0 to 100 ℃ then decreases at higher temperature, but cooking loss increases gradually with increase of temperature. These changes are caused by heat induced denaturation of meat protein. Myofibrillar protein and connective tissue as two main component of meating protein, their denaturation in thermal process is major factors affecting meat tenderness.

Key words: meat, cooking, tenderness, connective tissue, myofibrillar protein
