摘要:

【目的】明确椰子汁煮制文昌鸡的品质特征,为文昌鸡和椰子汁成分互作机理的研究和标准化生产提供有效依据。【方法】以文昌鸡和海南椰青为主要原料,利用电子鼻、气相色谱-质谱联用技术,结合气味活性值和主成分分析,对椰子汁煮制文昌鸡和水煮文昌鸡鸡胸肉和鸡腿肉的气味物质进行分析对比,利用电子舌、游离氨基酸和核苷酸检测技术对鸡胸肉和鸡腿肉的滋味物质进行分析,并且测定鸡肉和椰子汁的理化指标,以及椰子汁煮制鸡肉和水煮鸡肉的蒸煮损失、质构指标,明确经过椰子汁煮制后文昌鸡品质特征的变化。【结果】鸡腿肉中蛋白含量为21.0 g/100g,脂肪含量为3.08 g/100 g,鸡胸肉中蛋白含量为23.6 g/100 g,脂肪含量为1.29 g/100 g;椰子汁中的还原糖含量为4.75 g/100 g;椰子汁煮制的鸡肉和水煮鸡肉相比,蒸煮损失较高,两者质构指标相关性不显著(P>0.05);经过椰子汁煮制后鸡肉中新产生了2-庚醛、(E)-2-辛烯醛、(E)-2-壬烯醛、2,5-二甲基苯甲醛、2-十一烯醛5种醛类物质,电子鼻基本上可以将水煮鸡腿肉和椰子汁煮制鸡腿肉的挥发性物质区分开;经过椰子汁煮制后鸡腿肉和鸡汤的甜味氨基酸含量上升,但水煮鸡腿肉、鸡胸肉以及肉汤中的鲜味氨基酸均比椰子汁煮制后鸡肉的含量高;椰子汁煮制的鸡肉中鲜味核苷酸5'-AMP、5'-IMP和5'-GMP含量均高于水煮鸡肉。【结论】在文昌鸡不同部位中,鸡腿肉脂肪含量较高而鸡胸肉蛋白含量较高;椰子汁煮制可以提高文昌鸡肌肉核苷酸及鸡腿肉中游离氨基酸含量,对滋味有显著提升作用;椰子汁煮制增加了文昌鸡鸡腿肉中的醛类化合物种类,鸡腿肉比鸡胸肉有更好的风味形成效果。

Abstract:

【Objective】The aim of this study was to clarify the quality characteristics of Wenchang chicken cooked with coconut water, so as to provide an effective basis for the research on the interaction mechanism of Wenchang chicken and coconut water components and the standardized production.【Method】With Wenchang chicken and Hainan green coconut as the main raw materials, the odor substances of Wenchang chicken, Wenchang chicken breast meat, and chicken leg meat cooked with coconut water were analyzed and compared using an electronic nose and gas chromatography-mass spectrometry (GC-MS), combined with odor activity value (OAV) and principal component analysis (PCA). The taste substances of chicken breast meat and chicken leg meat were analyzed using electronic tongue, free amino acid, and nucleotide detection techniques. The physical and chemical indexes of chicken and coconut water, as well as the cooking loss and texture indexes of coconut-boiled chicken and water-boiled chicken, were determined to clarify the changes in the quality characteristics of Wenchang chicken after cooking with coconut water.【Result】The protein content in chicken leg meat was 21.0 g/100 g, and the fat content was 3.08 g/100 g. The protein content in chicken breast meat was 23.6 g/100 g, and the fat content was 1.29 g/100 g. The content of reducing sugar in coconut water was 4.75 g/100 g. The cooking loss of chicken cooked with coconut water was the highest compared with that boiled with water, and there was no significant correlation between the two texture indicators (P>0.05). After cooking with coconut water, five new aldehydes were produced in the chicken, namely 2-heptanal, (E)-2-octenal, (E)-2-nonenal, 2, 5-dimethyl benzaldehyde, and 2-undecenal. The electronic nose was able to distinguish the volatile substances in boiled chicken legs from those in coconut water. After cooking with coconut water, the content of sweet amino acids in chicken legs and chicken soup increased, but the content of savory amino acids in boiled chicken legs, chicken breasts, and broth was higher than that in chicken cooked with coconut water. The contents of 5'-AMP, 5'-IMP, and 5'-GMP in chicken cooked with coconut water were higher than those in boiled chicken.【Conclusion】The fat content in the chicken leg and protein content in the chicken breast differed in various parts of the Wenchang chicken. Boiling Wenchang chicken with coconut water increased the nucleotide content in the muscles and the free amino acid content in the chicken leg meat, significantly enhancing the taste. Boiling Wenchang chicken with coconut water increased the types of aldehydes in the thigh meat, and resulted in better flavor formation than the breast meat.
