Abstract

2-Oxo-imidazole dipeptides (2-oxo-IDPs) are highly functional, but it is unclear whether 2-oxo-IDPs exist in meat. Here, we measured 2-oxo-IDPs levels in meat and observed that they varied according to animal species and body parts. In addition, 2-oxo-IDPs in chicken breast extract increased after aeration in the presence of CuSO4/ascorbate, suggesting the potential of elevated 2-oxo-IDPs in effective usage of meat.

摘要

2-氧代亚氨基酸二肽（2-oxo-IDPs）具有高度功能性，但目前尚不清楚肉类中是否存在 2-oxo-IDPs。在这里，我们测量了肉类中的 2-oxo-IDPs 水平，发现它们根据动物种类和身体部位而有所不同。此外，在 CuSO4/抗坏血酸存在下，鸡肉提取物中的 2-oxo-IDPs 在充气后增加，这表明在有效利用肉类方面，2-oxo-IDPs 的含量可能会升高。
