1 furan, were identified. In addition, twenty non-esterified volatile compounds, consisting of alcohols, aldehydes and acids, were also identified as major non-esterified components. Furanoid compounds of 18 carbon atoms formed by a different route were also identified in this study. Overall, the composition of the small fraction originated from hydroperoxide scission provides a clear idea of the complexity
GC-MS和GC-FTIR可以互补地用于鉴定在油炸条件下加热到180°C的
油酸甲酯和
亚油酸酯形成的氧化化合物。该研究的重点是通过氢过氧化物裂解产生的化合物,这些化合物保持附着在油脂中的
甘油主链上并形成非挥发性分子的一部分。鉴定了二十一种短链酯化化合物,该化合物由8个醛,3个甲基酮,4个伯醇,5个
烷烃和1个
呋喃组成。另外,由醇,醛和酸组成的二十种未酯化的挥发性化合物也被确定为主要的未酯化组分。在这项研究中还鉴定了通过不同途径形成的18个碳原子的
呋喃类化合物。全面的,
