separately for their volatile composition. In-depth GC/MS analysis of the separate fractions revealed several unknown molecules. Mass spectra interpretation allowed us to identify nine molecules for the first time in chicken, including cyclic aldehydes, cyclic ketones, and new δ-lactones containing an unsaturated linear chain. Identification was confirmed by chemical synthesis followed by comparison
用不同的方法(烤,)将几个鸡肉部分(皮肤,脂肪,果汁)煮熟,并分别检查其挥发性成分。分离级分的深入GC / MS分析显示了几个未知分子。质谱分析使我们首次在鸡中鉴定出9个分子,包括环状醛,环状酮和含有不饱和线性链的新δ-内酯。通过化学合成确认鉴定,然后比较质谱和线性保留指数。在天然产物中首次报道了其中五个分子的天然存在。
