Scientists develop 14p patches for food containers that stop chips from going soggy

There’s nothing worse than treating yourself to a delicious takeaway, only to discover that your chips are soggy when they arrive.

But the days of eating limp fries could soon be a thing of the past, thanks to a new patch designed to prevent food deteriorating between the restaurant and your door. 

The patch sticks to the inside lid of the food container and absorbs condensation, keeping the contents fresh while in transit.

The patches are expected to cost just $2 (£1.47) for a pack of 10, suggesting they could offer restaurants a budget-friendly way to keep their customers’ food fresh.

HOW DO THE PATCHES WORK?

Air contains moisture, which condenses out of the air when it reaches ‘dew point’ – the temperature at which can no longer hold all of its water vapour.

This usually means that your takeaway gets covered in liquid water, causing your food to become soggy.

To combat this issue, the SAVRpak patches are actually frozen.

Its designers explained: ‘Following the laws of thermodynamics, the frozen SAVRpak exists at a temperature beneath the dew point and actively draws moisture from the air.

‘The ice inside the patch provides extra extraction power, keeping your food fresher without harmful chemicals.’

The patches were developed by California-based start-up SAVRpak, and work by removing moisture within takeaway boxes.

On its website, SAVRpak explained: ‘Condensation is the enemy of fresh food.

‘But all food creates condensation — whether it’s french fries, chicken wings, or salad.

‘The patented SAVRpak is a frozen peel-and-stick patch that forces moisture from the air of a container before it converts into condensation. The patch then traps the moisture to keep it away from your food.’

According to the company, the patches can reduce humidity in food containers by up to 45 per cent, keeping food fresh and crisp.

While you might worry that a frozen patch would cause your food to become cold, thankfully SAVRpak reassures that this isn't the case

It added: ‘The ice in SAVRpak will not make hot food cold. Simply put, it takes more energy to force vapor out of the air than it does to make ice melt. While SAVRpak reduces humidity, it only lowers the ambient temperature by 5%.’

The patches are already being used by several food distributors and restaurants in San Diego

Now, SAVRpak plans to trial selling the patches in large shops in the US, such as Walmart and Target. 

The company has not yet announced any plans to expand outside of the USA.
