Reducing meat and fish waste with a simple, handheld device

A nanotechnology solution delivers more accurate ‘best by’ dates for meat and fish products in an instant. The easy-to-use device could help save tonnes of edible food products and shrink the carbon footprint linked to their production and destruction.

Food and Natural Resources

According to estimates, 173 kg of food per person are wasted every year in the EU, generating a total of 170 million tonnes of CO2. A large share of this pollution is caused by meat and fish products: “10 % of all meat and 50 % of all fish produced are wasted due to doubts about their freshness and incorrect expiration predictions by the industry,” says Jeanette Hvam, CEO of Danish deep tech start-up AmiNIC.

Reducing human error

Her company has developed a surprisingly simple solution to this major global challenge. Currently shelf-life estimates are based on human senses or generic microbial data. AmiNIC developed a handheld device capable of measuring the freshness and determining a more accurate expiration date for meat and fish within seconds. The device involves a patented nanotechnology solution using a micro-cantilever which acts as a sensor. It measures the concentrations of cadaverine, an organic compound found in decomposing animal tissue. “The vibration of the cantilever changes when cadaverine is detected. This change is proportional to the age of the meat or fish,” Hvam explains. By comparing the measurements to expiry-prediction curves in a database, the device then returns a precise expiration date.

High precision

The EU-funded Food waste reduction project enabled AmiNIC to expand and strengthen the team with key competences. As a result, the researchers could perfect the tailor-made microsensor, significantly improving the output signal of the device. “We were able to increase sensitivity and resolution, which are essential to achieving the required precision, speed and reliability of the measurements,” Hvam notes. “As a bonus, the project has generated great added value and patentable knowledge that boost our exploitation potential.”

Major impact

Her team has been able to take significant steps towards bringing their technology to the market. During the project, device prototypes were tested by customers from different sectors including restaurants and the food processing industry. “Many field test users and potential customers show great interest in our solution, and we have sold our first units as pilot sales,” Hvam adds. Implementing the solution in meat and fish handling businesses could achieve not only a major economic impact, but also a significant reduction of our carbon footprint. “It is especially detrimental to the environment to waste meat and fish, as their production generates on average seven times more pollution than other food products,” Hvam explains. “A 40 % implementation of our solution in our target segments will potentially reduce our carbon footprint from food waste by 6 %.”
