New OLEUM publication in the MDPI Journal Foods

The category of virgin olive oil is currently assigned on the basis of chemical-physical and sensory parameters following official methods. Considering the limited number of samples that can be analysed daily by a sensory panel, an instrumental screening tool could be supportive by reducing the assessors’ workload and improving their performance. The approach is based on the volatile fraction fingerprint obtained by HS-SPME–GC–MS from more than 300 virgin olive oils from two crop seasons. Performing the screening approach, only the virgin olive oils classified as uncertain would be assessed by a sensory panel, while the rest would be directly classified into a given commercial category. The sensory panel’s workload would be reduced to less than one-third of the samples.
