Responsive food packets could warn us when frozen food has got too warm, or even if meat has gone off, and they could be on supermarket shelves within the next few years.
‘If you have a product like fish you would smell that it’s bad by opening the package, but there are other types of food products that you may not smell,’ said Marie Shrestha, coordinator of the EU-funded project IQ-FRESHLABEL.
The project has developed a label that changes colour so people can visibly detect the quality of the produce they’re about to buy, or have stored in their fridge or freezer.
They’ve made one for frozen fish and another for fresh poultry. The poultry label uses an oxygen sensor because these products often use a modified atmosphere with less oxygen inside the package which extends the shelf life by slowing down the growth of bugs.
‘If you have more oxygen due to a leakage, this leads to faster spoilage,’ said Shrestha, from ttz Bremerhaven, a research organisation in Germany. ‘An oxygen label can show you that you have too much oxygen in your package.’
Researchers on the project, which finished in 2014, also found that people can see the benefit in intelligent food labelling. Interviews with more than 2 000 consumers found that they would be willing to pay EUR 0.20 more for products with this type of packaging.
Another group of researchers has found a way to make food wrappers measure compounds given off by rotting meat.
‘The final output will be the consumer getting information about the real shelf-life of the product they are purchasing.’

‘This packaging will consist of sensors integrated into a film. These will measure volatile organic compounds produced by the meat when it’s spoiled,’ said Dr Silvia García Ruiz, from the EU-funded TOXDTECT project.
‘The final output will be the consumer getting information about the real shelf-life of the product they are purchasing,’ said Dr García, scientific project manager at the meat industry association ASINCAR in Spain, which is one of the four industry association project partners.
The three-year project began last year, and they believe the new packaging could be used in supermarkets by 2017. Current research focuses on beef but the team hopes to extend their research to other types of meat at a later stage.
Smart food sensors are also being developed that will help food safety experts trace the source of contamination in case of disease outbreaks and allow farmers to check the level of pesticides on their crop before harvesting.
In the past, farmers and food processors have sent samples for analysis. However, the EU-funded project FOODSNIFFER is developing a handheld sensor that can pick out contaminants such as mycotoxins, pesticides and allergens.
The project has made a scaled-down version of a laboratory test which measures the binding of these contaminants to targets within the sensor.
The researchers are halfway into their project and envisage a laboratory-grade portable product being commercialised by 2017.
The number of undernourished people rose for the first time in over a decade in 2016 due to conflict and climate change, and more research is needed into how to increase the security of people’s food supply and manage migration, according to Cristina Amaral, Director of the FAO (UN Food and Agriculture Organisation) liaison office with the European Union and Belgium. She is due to speak about investing in food systems and rural development to change the future of migration on 16 October at the Harnessing Research and Innovation for FOOD 2030 conference in Brussels, Belgium.
To stand a chance in the war against infectious diseases, European researchers need to make preparations in ‘peacetime’ to give us the best chance of fighting the next epidemic when it comes, according to Professor Yves Lévy, Chief Executive of Inserm, the French National Institute of Health and Medical Research.
Astronomers have witnessed a collision between two neutron stars for the first time, thanks to a tie-in between gravitational wave observatories and 70 telescopes around the world.
Orbiting the sun from far beyond planet Neptune, the recently discovered planetoid Haumea is a fast-spinning elongated object, completing one rotation every four hours. Now, following fresh observations, astronomers have discovered this dwarf planet also has a ring system in orbit around it.
Astronomers have seen gold being formed for the first time.
The structure rotates three times slower than the planetoid itself.
Food insecurity leads to increased migration, says Cristina Amaral.
