Although the EZ-DripLoss method has been performed in numerous studies, there is a deficiency in our knowledge of the EZ-DripLoss method's suitability for poultry meat analysis. This study aimed to research the effect of different sample areas (10, 20, and 30 mm; = 240), and fiber orientations (vertical vs. horizontal) on the EZ-DripLoss in chicken breast meat measured across a period of five days. The influence of sample area on the EZ-DripLoss of chicken breast meat with respect to the fiber orientation and across the five-day measurement interval was significant between 10 and 30 mm samples, and between 20 and 30 mm samples ( < 0.001). The estimated regression coefficient showed that EZ-DripLoss for the samples with horizontal and vertical fiber direction of 10 and 20 mm, significantly increased by 0.04% per hour, while for the samples with vertical fiber direction whose diameter was 30 mm, it significantly increased by 0.06% per hour, and for the horizontal fiber direction, it significantly increased by 0.07% per hour. The samples with vertical fiber orientation had 0.50% greater EZ-DripLoss compared to the samples with horizontal fiber orientation. EZ-DripLoss evaluation in chicken breast should be performed with a sample core diameter of 20 mm, a vertical fiber orientation, and over the course of longer measurement intervals.
尽管EZ-滴水损失法已在众多研究中得到应用,但我们对该方法在禽肉分析中的适用性了解不足。本研究旨在探究不同样本面积(10、20和30毫米;n = 240)以及纤维方向(垂直与水平)对鸡胸肉在五天时间内测量的EZ-滴水损失的影响。样本面积对鸡胸肉EZ-滴水损失的影响,在10至30毫米样本之间以及20至30毫米样本之间,相对于纤维方向和五天测量间隔而言具有显著性(P < 0.001)。估计回归系数表明,纤维方向为水平和垂直的10毫米和20毫米样本的EZ-滴水损失每小时显著增加0.04%,而纤维方向为垂直、直径为30毫米的样本每小时显著增加0.06%,纤维方向为水平的样本每小时显著增加0.07%。纤维方向为垂直的样本比纤维方向为水平的样本的EZ-滴水损失高0.50%。鸡胸肉的EZ-滴水损失评估应采用20毫米的样本芯直径、垂直的纤维方向,并在更长的测量间隔内进行。
