Real-time ripeness information for fruits with RFID | 02-07-2019 |

Packaging that can relay real-time information about the ripeness of avocados and other fruits contained inside was recently launched at Italian fresh produce trade fair Macfrut in Rimini. Called Smart Ripe, the new technology has been developed by Italian company Ilip in collaboration with Radio6ense, a spin-off of the University of Rome Tor Vergata, and the University of Turin’s Department of Agricultural, Forest and Food Sciences.

Ilip says the system uses a highly sensitive radio-frequency identification (RFID) tag embedded within the packaging. This can detect certain dielectric variations in the fruit pulp associated with ripeness, such as turgidity, acidity and water and sugar content. It has the potential to bring new value to fresh produce by ensuring consumers get exactly the product quality and shelf-life they want, according to the company.

The information gathered is transmitted to a terminal that can indicate if the fruit is ripe. Smart Ripe has been trialled for avocados. In addition it is able to provide useful information not just on when to eat the fruit, but also on how to use it – for example, in cooking, salads, sauces, etc.

While the technology is currently designed for premium fruit and vegetable products such as tropicals (avocado, mango and papaya), the principle can be applied to different types of fruit or vegetable, claims Ilip.

“Smart Ripe is the first technology that can monitor – in real-time and in a non-invasive way – the freshness and ripeness of a fresh product,” states Luigi Garavaglia, R&D manager at Ilip. “With this innovation, we are paving the way to numerous applications that will improve handling of fruit and vegetables at the point of sale as well as the consumer purchase experience.”

Roberto Zanichelli, business development and marketing director at Ilip, added, “Smart Ripe is an innovation that we are very proud of because it is a step towards packaging that not only offers protection and conservation, but also a value creation factor for the supply chain.”

“At a time in which plastic packaging is also facing criticism, we are proposing a vision in which packaging sustainability also involves advanced features that create value and improve supply chain management,” he stressed.
