Table 8: Relative area of volatile organic compounds (VOC) of honey samples from the three investigated zones (Z1 - Z3). We can also observe a higher benzaldehyde content, especially in Zone 1 honey (7.23%), as compared to the one in Zone 2 (3.89%) and Zone 3 (4.68%). Benzaldehyde was identified as being a relevant compound in lavender, acacia and rosemary honey [65; 72]. [PERSON] et al. [73] identified benzaldehyde as being a volatile marker in Corsican chestnut honey with a 10.8% concentration.
