Ultrason Sonochem. 2024 Mar;104:106824. doi: 10.1016/j.ultsonch.2024.106824. Epub 2024 Feb 24.
Ultrasonication, a technology that employs high-frequency sound waves, has demonstrated potential for modifying the properties of various food items. However, the effect of ultrasonication on chicken meat, particularly concerning amino acid composition and flavor enhancement, has not been sufficiently investigated. The objective of this research was to bridge the gap in the literature by exploring the impact of various ultrasonic treatments at varying power levels (300, 500, and 800 W) and durations (10 and 30 min) on the physicochemical characteristics, texture, and amino acid profile of chicken breast meat, with a focus on improving its palatability and flavor. The results indicated that ultrasonication reduced the pH and cooking loss, as well as hardness and chewiness while simultaneously increasing lightness and yellowness values of chicken breast meat. Moreover, ultrasonication enhanced the amounts of essential amino acids, including glutamic acid, alanine, and glycine as well as the free amino acid content, which gives meat its savory and umami flavor. Furthermore, the results demonstrated significant changes in the texture and structure, as demonstrated by the scanning electron microscopy (SEM) images, and in chemical makeup of chicken breast meat, as indicated by the FTIR spectra. These modifications in the molecular and microstructural characteristics of meat, as induced by ultrasonication, may contribute to the enhancement of tenderness, juiciness, and overall palatability.
超声处理是一种利用高频声波的技术,已被证明可以改变各种食品的特性。然而,超声处理对鸡肉的影响,特别是对氨基酸组成和风味增强的影响,尚未得到充分研究。本研究旨在通过探索不同功率水平(300、500 和 800 W)和不同时间(10 和 30 分钟)的各种超声处理对鸡胸肉的物理化学特性、质地和氨基酸组成的影响来填补这一文献空白,重点是改善其可接受性和风味。结果表明,超声处理降低了鸡胸肉的 pH 值和蒸煮损失,同时硬度和咀嚼性降低,而亮度和黄度值增加。此外,超声处理增加了必需氨基酸(包括谷氨酸、丙氨酸和甘氨酸)和游离氨基酸含量,这些氨基酸赋予了肉的鲜美和鲜味。此外,扫描电子显微镜(SEM)图像显示,超声处理导致鸡肉的质地和结构发生显著变化,傅里叶变换红外光谱(FTIR)显示鸡肉的化学成分发生变化。这些超声处理对肉质的分子和微观结构特性的改变可能有助于提高嫩度、多汁性和整体可接受性。
