Valódi vagy hamis az olívaolaja? Az élelmiszer-detektívek DNS-tesztekkel leplezik le a csalást
Európa legjobb élelmiszer-biztonsági szakértői összefognak a csalások megfékezése érdekében. Az Euronews őket követi nyomon a The Food Detectives című sorozatában. A 6. epizódban a hamisított olívaolaj ellen küzdő csapattal tartunk, akik egy hordozható DNS-tesztkészletet vetnek be Olaszországban.
Együttműködésben a the European Union & the Watson Project
00:01Europe's best food safety experts are joining forces to crack down on fraud.
00:06Euronews is following them in this special series called The Food Detectives.
00:10In this episode, we're following the team fighting counterfeit olive oil in Italy.
00:23Every drop of olive oil has its own story.
00:27But sometimes, what looks like the real deal is in fact counterfeit.
00:53Such fraud may impact consumer health,
00:55and it's done for easy profit.
00:58The price of oil can vary from little to a very high value.
01:02So there's a big fork inside which we can verify fraud.
01:06This is aggravated by the fact that the value of oil is extremely fractured.
01:12So, olive oil maker Antonella Meyer-Mashvili is working with the food detectives from the EU's Watson project and their mission to beat fraud.
01:23Her secret weapon is genetic code.
01:25She uses DNA tests to guarantee the identity of her oils.
01:29We've chosen to analyze our oils in DNA to create more transparency and confidence in our consumers.
01:40Many producers do marketing with photos of millenaries.
01:47But at the end, it's not about oil in these trees.
01:50And we, to make us credible, have this certification.
01:54Because it's a certainty that we give to our consumers.
02:00Such genetic testing is still very rare among olive oil producers as it takes time and money.
02:13Until today, it's only been done in research labs.
02:16But the food detectives are now bringing the lab directly to the mill.
02:20Release our DNA.
02:21Greek biotech experts Stelios Arhandakis and Sophia Tsikaraki are developing a solution to make DNA testing more accessible and easier to carry out.
02:32We just opened the door for the first time in the world to do a DNA testing of an olive oil outside of a lab.
02:41We are introducing a device called Field DNA.
02:45This device allows to isolate DNA from an olive oil sample in field conditions.
02:54So that's it. We are ready to analyze our DNA.
03:00The food detectives' portable DNA kit still needs refining, but it's on the right track.
03:06The development of a technology is always a challenge because you need to validate, you need to test it, you need to optimize until you reach a good performance.
03:18And be sure that you have something that is solid.
03:21It is a path that we are under now, we're investigating.
03:25Hopefully to be able to launch this product within the next month, year.
03:30Producers, millers and packages across Umbria welcome the innovation.
03:37It's the base, it's what can help us companies, us olive oil farmers, to protect the territory and the product that we do.
03:49To have an analysis that guarantees that that product comes from that plant is the most beautiful thing we can do.
03:56Watson's project gives us clarity and the final consumer is asking and looking for it more.
04:04Following the DNA tests, the food detectives are taking traceability one step further by giving each bottle a digital passport too.
04:12All the data that has been collected during the production chain of olive oil,
04:19are guaranteed within the blockchain, but are made accessible to the consumer,
04:25which can easily access through AquaRecode to the entire history of olive oil,
04:31from the field where olive oil are being produced,
04:35to the number of the bottle that has been acquired.
04:38That's it for this episode of The Food Detectives.
