The main objective of this project is to develop an integrated rapid, simple and sensitive analytical method enabling assessment of saffron authenticity. With this aim we propose a multiple and integrated MS-based metabolomic approach, comparing both untargeted profiling and targeted marker identification for saffron authenticity. This will employ High Resolution Mass Spectrometry method coupled with DART or LC techniques. In fact, DART technology offers several advantages compared to conventional techniques, such as the possibility to analyze sample directly in the open atmosphere without previous chromatographic separation, high sample throughput and minimal, or no sample preparation requirements.
In addition, we propose a spectroscopic and imaging identification of all saffron components using the Time of Flight Secondary Ion Mass Spectrometry. This technique, which probes the chemistry and the structure of the outer surface, is known for its molecular specificity, relatively high mass resolution, and high sensitivity. It is also considered a non-destructive technique that analyzes samples in the micro scale. Compared to conventional techniques, TOF-SIMS turns very useful technique in case of very low quantity of samples available and does not require a chemical sample preparation. The goal of the project would be to identify marker to safeguard saffron authenticity by using an integrated approach.
