摘要
猪肉胴体来自澳大利亚的三个屠宰场(n = 345),屠宰场采用的技术能够收集屠宰后的 P2 脂肪深度(毫米)测量值(Hennessy Grading Probe (HGP)、AutoFom III、PorkScan Lite)和胴体瘦肉率估计值(HGP、AutoFom III、PorkScan Plus)。计算机断层扫描(CT)用于扫描胴体并确定瘦肉率和脂肪率,同时确定与屠宰场测量设备的关联强度。AutoFom III 瘦肉率与整个胴体 CT 瘦肉率(R2 0.63,RMSE 1.73)和脂肪率(R2 0.68,RMSE 1.80)以及切片(前部、腰部、腹部和后部)CT 成分的关联性最强。相比之下,AutoFom III 的 P2 关联度较低,但仍优于其他商用设备(PorkScan Lite 和 HGP)。Porkscan Plus 瘦肉率与整个胴体和切片 CT 瘦肉率和脂肪率的关联度适中,R2 值一般不到 AutoFom III 的一半。使用瘦肉率或 P2 输出,HGP 与 CT 瘦肉率和脂肪率的相关性最弱,这可能与只从 P2 测量点收集数据有关。这是澳大利亚首次比较多种猪肉屠宰场测量设备与 CT 瘦肉率和脂肪率之间关联强度的实验。P2 是目前评估猪肉瘦肉率的行业标准,但它与胴体 CT 成分的关联性要弱于 AutoFom III 和 PorkScan Plus 等能够捕捉胴体多种测量值的设备。
The association of P2 and lean % estimates from commercial measurement systems with computed tomography determined composition within Australian pork abattoirs
Pork carcasses were obtained from three abattoirs in Australia (n = 345) where technologies enabled collection of post slaughter measures of P2 fat depth (mm) (Hennessy Grading Probe (HGP), AutoFom III, PorkScan Lite) and estimates of carcass lean % (HGP, AutoFom III, PorkScan Plus). Computed tomography (CT) was used to scan carcasses and determine lean and fat %, with the strength of associations with abattoir measurement devices determined. The AutoFom III lean % demonstrated the strongest associations with whole carcass CT lean % (R2 0.63, RMSE 1.73) and fat % (R2 0.68, RMSE 1.80) and with section (fore, loin, belly and hind) CT composition. The association of P2 from AutoFom III was lower in comparison, however remained superior to other commercial devices (PorkScan Lite and HGP). Porkscan Plus lean % demonstrated moderate associations with whole carcass and section CT lean and fat %, with R2 values generally less than half those of the AutoFom III. The HGP demonstrated weakest associations with CT lean and fat % using either lean % or P2 outputs, which is likely related to data being collected from only the P2 measurement site. This is the first experiment to compare the strength of associations between multiple pork abattoir measurement devices and CT lean and fat % in Australia. P2 is the current industry standard for the assessment of lean yield in pork, however demonstrates weaker associations with carcass CT composition than devices capable of capturing multiple measures across the carcass like AutoFom III and PorkScan Plus.
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.
