This research evaluated the properties of cured chicken breasts of broiler chicken with different marketing ages (28, 30, 32, and 34 day). The water contents in the proximate compositions of the samples tended to decrease with increasing marketing age, while the protein content increased. The samples' uncooked and cooked pH values, WHC, and cooking yield increased with increasing marketing age; however, the WHC and cooking yield were not significantly different between the 32 and 34 day samples ( > 0.05). In the case of the color, the 34 day samples were significantly lower in terms of lightness, but significantly higher in redness and yellowness compared to the other samples ( < 0.05). Although the shear forces of the 28-32 day samples were not significantly different ( > 0.05), those of the 28 and 30 day samples were significantly lower than those of the 34 day sample ( < 0.05). Furthermore, the aromatic profile (determined by principal component analysis) of the 34 day sample differed from that of the 28-32 day samples. Flavor evaluation of the cooked 30 and 32 day samples showed significant differences compared to the 28 and 34 day samples ( < 0.05), and the texture evaluation showed that the 34 day sample obtained a significantly lower score than the 28 day sample ( < 0.05). Overall, these results suggest that the current broiler marketing age of 32 day results in suitable quality properties for broiler cured chicken breast.
本研究评估了不同上市日龄(28、30、32和34日龄)的肉鸡鸡胸肉腌制后的特性。样品近似成分中的水分含量倾向于随着上市日龄的增加而降低,而蛋白质含量则增加。样品的生肉和熟肉pH值、保水性和烹饪产率随着上市日龄的增加而增加;然而,32日龄和34日龄样品之间的保水性和烹饪产率没有显著差异(P>0.05)。在颜色方面,34日龄的样品亮度显著较低,但与其他样品相比,红色度和黄色度显著较高(P<0.05)。虽然28 - 32日龄样品的剪切力没有显著差异(P>0.05),但28日龄和30日龄样品的剪切力显著低于34日龄样品(P<0.05)。此外,34日龄样品的香气特征(通过主成分分析确定)与28 - 32日龄样品不同。对30日龄和32日龄熟肉样品的风味评价与28日龄和34日龄样品相比有显著差异(P<0.05),质地评价表明34日龄样品的得分显著低于28日龄样品(P<0.05)。总体而言,这些结果表明目前32日龄的肉鸡上市日龄能使腌制鸡胸肉具有适宜的品质特性。
