Scientifically confirmed mono-floral honey
Scientists from the University of Western Australia have developed an analytical method to confirm the honey nectar source for a number of Australian mono-floral honeys. The method uses High Performance Thin Layer Chromatography (HPTLC) and analyses the non-sugar fraction of a honey (Locher et al., 2018), which contains flavonoids and organic acids. By separating these components and analysing them at different lights (white light, 254 nm and 366 nm) prior and after chemical treatment (with Vanillin reagent) four different fingerprints are obtained which, taken together, can be considered a signature of the floral nectar derived components.
The analytical technique can also be used to obtain an antioxidant fingerprint of the honey (Islam et al., 2020).
The use of the following Trade Marks scientifically confirms the dominant source of nectar is from the species identified.
