摘    要:为研究中国西门塔尔牛的肌纤维和肉品质特性,本试验以10头中国西门塔尔公牛为研究对象,测定了背最长肌、腰大肌和半腱肌的组织学特性、pH、系水力、剪切力和质构剖面分析。结果显示,肌纤维直径Ⅰ型 < ⅡA型 < ⅡB型,腰大肌中Ⅰ型具有最高的肌纤维数比例和肌纤维面积比,背最长肌和半腱肌中ⅡB型具有最高的肌纤维比例和肌纤维面积比。与腰大肌相比,背最长肌和半腱肌具有较低pH、弹性和压力失水率,较高的剪切力、硬度和回复性。综上所述,肌纤维特性影响牛肉品质,特别是牛肉的质构特性,提高Ⅰ型纤维比例和降低ⅡB型纤维比例能够改善牛肉嫩度。

关 键 词:中国西门塔尔牛  肌纤维类型  剪切力  质构剖面分析

Abstract:The aim of this test was to study muscle fiber characteristics and meat quality traits of Chinese Simmental cattle.Ten Chinese Simmental bulls were selected and longissimus dorsi,psoas major and semitendinosus were collected.Histological characteristics,pH,water holding capacity,shear force and texture profile analysis (TPA) were measured.The results showed that the diameter of these muscle fibers increased in the rank order type Ⅰ < ⅡA < ⅡB.The number and area percentage of type Ⅰ muscle fiber were highest in longissimus dorsi and that of ⅡB muscle fiber was highest in psoas major and semitendinosus.Longissimus dorsi and semitendinosus had lower pH,springiness,pressing lossing rate and higher shear force,hardness and resilience comparing with psoas major.In conclusion,muscle fiber characteristics could affect meat quality,especially textural properties of Chinese Simmental bulls.Increasing the percentage of type Ⅰ muscle fiber and decreasing ⅡB type could improve beef tenderness.
Keywords:Chinese Simmental cattle  muscle fiber type  shear force  texture profile analysis
