| Abstract: |
| A feasible approach for the analysis and identification of the complex components in mixed flavor was developed by moving window characteristic peak orthogonal projections resolution algorithm,GC-MS and the flavor database established.The analysis process was as follows:the compositions of mixed flavors containing five essential oils and three tinctures in unknown complex essence were firstly analyzed by GC-MS,and then moving window characteristic peak orthogonal projections resolution algorithm combined with the flavor database established was employed to distinguish the essential oils and tinctures in mixed flavors.Finally,the parameters related to the algorithm and the factors influencing the qualitative results were discussed in detail.The five essential oils and the three tinctures which were mixed into unknown complex essence were distinguished accurately by the presented method,and the obtained results indicated that the proposed approach was indeed a very effective and promising way for the analysis of complex components in mixed flavors. |
