Assessing a traceability technique in fresh oranges (Citrus sinensis L. Osbeck) with an HS-SPME-GC-MS method. Towards a volatile characterisation of organic oranges
The aroma profile of 360 oranges from conventional and organic systems was obtained. The volatile characterization of organic oranges is reported for the first time. The chemometric approach allowed discrimination of oranges based on cultivation practices. Potential volatile markers were identified according to the cultivation system. The suitability of HS-SPME-GC/MS technique as a traceability tool was assessed.
