Bump Mark is a food freshness checker that reacts to the environment around it, just like fresh food does and updates itself.
The label is checked by touch, so when it's smooth - your food is fresh. If you feel bumps - then it's time for the bin. The label only goes 'bad' when your food does too.
So, how does it work?
A gel that copies the bio-structure of the food it is labelling is set over a plastic bumpy sheet - because jelly is solid when it sets, you cannot feel the bumps underneath at first. When the gel expires, it turns back into a liquid and then you can feel the bumps underneath, letting you know that your food is bad.
What is it made from?
We have been using gelatine for the first version of the product to help determine when meat products go off. Gelatine is a natural food product which is high in protein, so it decays at the same rate as other protein foods and it can be calibrated to match different meats that have various decay rates.
We will be exploring this solution for other food groups in the future.
The label simply copies what the food inside the package is doing, so the expiry information is far more accurate than a printed date that can never update itself.
And because it's tactile, it's brilliant for people with visual impairments.
This award-winning food expiry label has a patent pending and our team are working hard to complete the research and development to bring the innovation to market. If you're interested in collaborating with us, please get in touch.
Isn't it about time that we had access to naturally accurate information?
