24 Jun 2022 — A workforce of biotechnology and blockchain specialists in Greece are utilizing olive oil DNA to generate a fraud-proof genetic barcode for every bottle. With funding from European analysis and innovation mission S3FOOD, the transfer is predicted to attenuate meals fraud throughout further virgin olive oil (EVOO).
The digital device will safeguard the authenticity and traceability of EVOO from the sector. For producers, it means cheaper imitations will not undercut the worth of high-end merchandise.
Customers can belief that the EVOO within the bottle lives as much as the designation on the label and is protected to eat.
Biodiversity advantages and past
As genuine EVOO positive aspects the popularity it deserves, growers may have a higher incentive to guard the biodiversity of olive tree varieties.
Stelios Arhondakis is CEO of BioCoS, which is working with expertise associate InTTrust to develop the anti-fraud traceability device DNAblockchain.
“The excessive danger of fraud within the olive oil trade may be very a lot associated to the product’s financial worth, fragmented provide chain and liquid nature. A latest research has discovered that the worth of a premium EVOO could also be diminished by 50%,” he says.
Olive oil fraud takes many kinds. In 2019, for instance, Europol seized 150 metric tons of sunflower oil, which the label claimed to be olive oil. One other case concerned 47 millers, two bottlers and merchants who offered oil with a faux EVOO Protected Geographical Location (PGI) label.
Traceability from tree to client
BioCoS is establishing DNA profiles for particular olive varieties used to provide EVOO to counter the issue. One kind – Koroneiki – accounts for round 60% of Greek EVOO manufacturing.
An clever knowledge processing platform makes use of DNA knowledge to confirm the varietal authenticity of EVOO. This data is then built-in right into a blockchain system together with different knowledge, comparable to high quality traits, the situation of the olive grove and the amount of EVOO produced.
The entire traceable story can be accessible to shoppers through a QR code on the EVOO bottle.
“Blockchain is already broadly used within the olive oil sector to trace and hint every lot quantity from the oil producer to the buyer. Nonetheless, the limitation of this strategy is that it ensures solely the traceability of the bottle – not its content material.”
“DNA-blockchain bridges this hole, making it unattainable to combine olive oil with different varieties or different sorts of vegetable oil with out being found. So, if you happen to add 3-5% olive oil from a Greek selection to an Italian product, you’ll be capable to hint it through DNA evaluation. That provides full transparency,” Arhondakis says.
Along with the advantages for industrial manufacturers and meals security, the DNA knowledge can be utilized to create a ‘geo-genetic’ map of olive growers producing EVOO. Arhondakis believes this might develop into a necessary useful resource for future efforts to enhance the sustainability of olive cultivation and mitigate local weather change dangers.
