In two separate experiments, carcasses of intact Kiko × Boer male kids were assigned randomly to tension treatments applied 30 min postmortem: 1) suspended by the Achilles tendon (AT); 2) suspended from the pelvic bone with front and hind legs tied together (TS); or 3) suspended by the Achilles tendon, and the fore- and hindsaddle were separated at the 12th/13th thoracic intervertebral disk, external fat, accessory muscles and epimysium surrounding the longissimus muscle (LM) were cut (TC), and a 2.3-kg weight attached to the neck (TC + W). Warner-Bratzler shear force values for the LM were reduced (P < 0.05) 24.4 to 35.9 N in TS carcasses compared to AT carcasses, and WBSF values of SM from TS carcasses were 25.0 and 20.3 N less (P < 0.05) than those for AT and TC + W carcasses, respectively. Results indicated that cooked goat meat tenderness, particularly the LM and SM, may be improved greatly by suspending goat carcasses by the pelvic bone.

在预应力山羊尸体上施加张力以改善熟肉的嫩度

在两个独立的实验中,将尸体完整的Kiko×Boer男童的尸体随机分配到死后30分钟进行张力治疗:1)由跟腱(AT)悬吊;2)将前腿和后腿绑在一起,从骨盆悬吊(TS);或3)由跟腱悬吊,并在第12/13胸椎椎间盘分离前鞍和后鞍,切掉了背肌(LM)周围的外部脂肪,辅助肌肉和上皮肌层(TC),并在2.3-脖子上附着的公斤重量(TC + W)。 与AT屠体相比,TS屠体的LM的Warner-Bratzler剪切力值降低了(P <0.05)24.4至35.9 N,TS屠体的SM的WBSF值降低了25.0和20.3 N(P <0.05),分别比AT和TC + W屠体高。结果表明,通过用骨盆骨悬吊山羊尸体,可以大大改善煮熟的山羊肉的嫩度,尤其是LM和SM。
