The Maillard reaction has been well researched and used in the food industry and the fields of environmental science and organic chemistry. Here, we induced the Maillard reaction inside human hair and analyzed its effects by using Fourier transform infrared spectroscopy with a focal-plane array (FTIR-FPA) detector. We used arginine (A), glycine (G), and D-xylose (X) to generate the Maillard reaction by dissolving them in purified water and heating it to 150 °C. This label-free process generated a complex compound (named AGX after its ingredients) with a monomer structure, which was determined by using nuclear magnetic resonance (NMR) and FTIR-FPA. This compound was stable in hair and substantially increased its tensile strength. To our knowledge, we are the first to report the formation of this monomer in human hair, and our study provides insights into a new method that could be used to improve the condition of damaged or aging hair.
美拉德反应已经在食品工业、环境科学和有机化学领域得到了充分研究和应用。在此，我们在人发内部引发美拉德反应，并使用带焦平面阵列（FTIR-FPA）探测器的傅里叶变换红外光谱对其效果进行分析。我们将精氨酸（A）、甘氨酸（G）和D-木糖（X）溶解在纯水中并加热至150°C，以引发美拉德反应。这个无标记过程生成了一种具有单体结构的复合化合物（根据其成分命名为AGX），通过核磁共振（NMR）和FTIR-FPA对其进行了鉴定。该化合物在头发中稳定存在，并显著提高了头发的拉伸强度。据我们所知，我们是首个报道在人发中形成这种单体的，我们的研究为可用于改善受损或老化头发状况的新方法提供了见解。
