Maillard reaction products (MRPs) with roasted/broth flavors were prepared and analyzed for the resulting flavor differences. The identification of volatile compounds in MRPs was carried out by GC-MS and GC × GC-ToF-MS. A total of 88 compounds were identified by GC-MS; 130 compounds were identified by GC × GC-ToF-MS, especially acids and ketones were identified. Principal component analysis (PCA) was used to visualize the volatile compounds, and the roasted/broth flavors were differentiated. The contents and types of pyrazines were more in roasted flavors; thiol sulfides and thiophenes were more in broth flavors. All in all, the differences in volatile compounds producing roasted/broth flavors were studied through the cysteine-xylose-glutamate Maillard reaction system, which provided a theoretical basis for the future use of Maillard reaction to simulate meat flavor.
制备了具有烘焙/肉汤风味的美拉德反应产物（MRPs），并分析了其产生的风味差异。通过气相色谱 - 质谱联用仪（GC - MS）和全二维气相色谱 - 飞行时间质谱仪（GC×GC - ToF - MS）对MRPs中的挥发性化合物进行鉴定。通过GC - MS共鉴定出88种化合物；通过GC×GC - ToF - MS鉴定出130种化合物，尤其是酸和酮类化合物。采用主成分分析（PCA）对挥发性化合物进行可视化分析，区分出烘焙/肉汤风味。烘焙风味中吡嗪类化合物的含量和种类更多；肉汤风味中硫醇硫化物和噻吩类化合物更多。总之，通过半胱氨酸 - 木糖 - 谷氨酸美拉德反应体系研究了产生烘焙/肉汤风味的挥发性化合物的差异，为未来利用美拉德反应模拟肉类风味提供了理论依据。
