How many days can a fillet maintain on the fridge? Three Spanish scientists invent a label to know if meals is unhealthy | Science | EUROtoday
Pilar Granado, Pablo Sosa and Luis Chimeno by no means imagined {that a} forgotten fillet within the fridge of their pupil ground in Elche would be a part of their lives. Was it fit for human consumption it? Was it higher to throw it? Years later, that anecdote would develop into the seed of an invention that has taken them to Iceland as one of many younger guarantees that aspire this 12 months to win the Young Inventors Prize 2025 (Young Inventors Award), a recognition awarded by the European Patent Office (OEP) for innovators below 30 years.
The machine is a clever label biosensor that enables suppliers and shoppers to test the freshness of perishable meals in actual time. “The technology we have designed uses intelligent indicators (molecules) inside the label. As bacteria multiply, they generate compounds that interact with the label indicator, causing a gradual color change from white to black,” explains Pilar Granado. Oscillum’s crew describes the label as a “a shield” to a number of invisible enemies. This coloration transition reacts to the Salmonellathe E. coli o to Listeriaamongst different micro organism, and it additionally serves for packaged meals as soon as they’re open. “The expiration date is a reference while the container follows in the same conditions, but once all its microbiological environment is open,” provides Luis Chimeno.
WHO estimates that yearly about 600 million individuals get sick from consuming contaminated meals. To keep away from this, many shoppers are normally guided by the looks of the merchandise or by the usual expiration dates to evaluate their freshness, nevertheless, this causes the pointless waste of nonetheless edible meals. The machine invented by these Spanish biotechnologists works in flesh, fish, fruit and ready meals. Its creators search that their use serves to scale back waste whereas providing certainty to the general public. “We realized the number of times we throw the forgotten food by eye and that we all have the same problem in our refrigerators,” replies Pablo Sosa.
It is estimated that greater than 1,000 million meals dishes are wasted every single day, in keeping with a latest report by the United Nations Environment Program, which represents 132 kilograms per particular person, or what’s the identical, a fifth of all meals accessible for human consumption and eight% of world greenhouse gases. “We have seen that in those markets in which food security infrastructure is not 100% optimized or is not a priority, such as countries of the African continent or Latin America, this technology solves a huge problem with little investment,” explains Chimeno. Of the full waste wasted in 2022, the UN says, 60% was discarded from properties, 28% corresponded to meals service suppliers and 12% to retail commerce.

The OEP grants the European inventor award yearly to acknowledge important contributions to innovation and technological growth and each two years organizes the Young Inventors Prize For younger researchers who use know-how and creativity towards world challenges according to the UN sustainable growth goals, 17 interconnected goals adopted by the United Nations in 2015 as a common motion plan to construct a greater and extra sustainable future. In the Spanish case, the label is biodegradable and seeks to scale back emissions, illnesses brought on by meals poisoning and meals waste.
The challenge has been financed thus far with public funds, together with these of the Center for Technological Development and Innovation (CDTI) of the Government of Spain that allowed them a number of years in the past to complete know-how. In 2017, they gained the primary entrepreneurship prize and Miguel Hernández de Elche University gave them an area of their scientific park. Granado, Sosa and Chimeno have additionally gained these years the awards The Gap in Betweenorganized by the platform Social Nest Foundation And they have been finalists of the agri -food awards EIT Food Innovation Prizesamongst different recognitions.
The Oscillum challenge is within the advertising part and seeks companions to fabricate the machine. “We have found a great reception among the consumer in Europe. What we are looking for here is to sell it directly in supermarkets since the industry is a bit more conservative in this type of technologies and what we want is for people to buy the label and can use it in their homes,” says Sosa.
Each of the ten tasks chosen on this 17 version of the awards has been rewarded with 5,000 euros. “[El certamen] It places inventors within the first departure line in entrance of different rivals and offers a status in direction of the invention and industrial growth, ”says Luis Berenguer, director of Communication and spokesman for the European Patent Office.“ At the same time, it helps to make our lives, that of all citizens, it is better ”, underlines. The jury will select this Wednesday, June 18, the winners of three From the general public, via the OEP web site, you’ll obtain extra 5,000 euros.
