Beko says that the technology was independently verified by quality assurance organisation Intertek. The company tested fruit and vegetables stored for a five-day period using the light tech against a control group kept in the dark. The produce tested included tomatoes, green peppers, carrots, spinach and celery.

If all this sounds like crazy talk – because after all, veg is veg and once picked, its lifecycle is over, right? – prepare to be surprised. This is much more plausible than it initially sounds.

In 2013, the publication Current Biology published an incredible study showing that even after being picked, the phytochemical composition of fruit and vegetables continued to alter in response to light. The team behind the study worked initially with harvested cabbages, before testing other produce, including sweet potatoes, blueberries, spinach and courgettes.  

In the early mornings, before sunrise, plants ramp up the production of chemicals used to deter insects. And this circadian rhythm continues on in their fruit after harvest. Some of these chemicals have a nutritional value to humans, and we can stimulate their production by recreating the natural light cycle.

Broadly speaking, that means that the right light at the right time can be used to make fruit and veg more nutritious. 

However, what we don’t know is whether this process is only disrupted or entirely ended during periods of transport (where the produce will be in total darkness) or storage (where it may be on display in a supermarket that’s lit for 24 hours a day). That means that the effectiveness of the fridge’s tech may be predicated on how long it takes for the produce to reach your home.

It could also mean that to take advantage of the increased nutrition, you'd have to eat the produce at a particular time of day.

However, if you grow your own fruit and veg or buy locally-grown produce, Beko’s new light tech could well help you to make the most of your fruit and vegetables.
