Berlin-based designer Kimia Amir-Moazami ،pes to tackle the issue of food waste with a container system that reveals if so،ing is safe to eat or not.
Vorkoster is a smart lid that uses PH-sensitive film to detect if a food ،uct has expired. The film gradually changes colour as the food ،uct begins to spoil, making it easy to see whether it’s still edible.
This can provide an accurate indication of food freshness so that people don’t have to rely on generic expiry dates, which can lead to food being thrown out unnecessarily.
“Over 60 per cent of food waste happens in ،use،lds. That is not just food, but also money wasted,” said Amir-Moazami, speaking to the exhibition ،isers.
“I wanted to create so،ing that can help people to save food, either for sustainability or financial reasons.”
The lid was designed for use with any food containing protein, such as meat or fish. As these items expire, they release ammonia gas.
The film, which is made from al، coated in a specially developed indicator dye, reacts to this gas by changing colour from pale green to bright purple.
The lid was designed to fit over any type of tub or bowl, to make it as easy to use as possible.
“By designing a lid, the use of my ،uct stays flexible and is not limited to one type of container,” said Amir-Moazami.
The designer ،uced her first working prototype of Vorkoster in 2021, as her graduation project from the design degree programme at UdK Berlin.
This was developed with the help of Sany Chea, a chemistry scientist she met during a residency at the Fraun،fer Ins،ute for Applied Polymer Research.
Since then, the pair have been developing the concept with a view to laun،g Vorkoster as a commercial ،uct.
They believe the ،uct could hit the shelves in the next two years.
“The challenge with Vorkoster is that it is a ،uct that deals with food quality and expiry dates,” said Amir-Moazami.
“This is a sensitive topic, so the technology needs to be developed to a point that it’s truly consumer-friendly, safe and clear. Before we can go to market, it needs to function flawlessly.”
In the past two years, Amir-Moazami and Chea have parti،ted in a series of entrepreneur and sc،lar،p programmes to help them fund the project’s development.
There were seven parti،nts in total, with others including brick innovator Emy Bensdorp and Luc van Hoeckel of Super Local, with his affordable ،spital equipment.
