A report released in 2013 showed that over 80% of the world’s fridges contain at least two sticks of mouldy celery, half a pot of old houmous and an out-of-date coconut yoghurt. OK, so we made that up, but the survey did reveal that £1bn (€1.3bn, $1.6bn) of edible food is wasted in the UK each year.
So food manufacturers will be interested to read about Solveiga Pakstaite’s new prototype bio-reactive Bump Mark, which lets people feel when food has passed its use-by date. The label contains a layer of gelatine over a bumpy surface; as the gelatine decomposes the bumps can be felt through the layer. Different ‘strengths’ of gelatine can be used for longer or shorter use-by dates.
23 year-old Miss Pakstaite, who has just finished her degree in Industrial Design and Technology, was inspired to create the project after working with visually impaired people on her course. And, having just picked up the James Dyson Foundation award for innovation, we’d guess she’s definitely feeling at her best.
