When you were a child, you might have tried to see if you could 'catch' the light turn on when you opened the refrigerator door, in order to work out if the light was constantly on or only turned on when the door was opened. Soon enough, you realised that it the fridge was always dark until it was opened. Nevertheless, recent scientific research might possibly change this fact.
You might never have thought about this, but did you know that the fruits and vegetables you store inside your small chest freezer are still alive? Just as cut flowers will live longer when given water and nutrients, so will fruits and vegetables live longer under the best conditions. Sure, you probably have a fruit and vegetable drawer, but it turns out that there is an even better way to extend the life of the produce we put in our fridges - light!
It actually makes sense that light helps produce live longer when you think about it. Light is necessary for plants to live because their very biology is made to respond to light. In their natural habitats they will experience the light of day and the darkness of night. As with many living creatures, darkness is a time of rest, while light is a time of activity. Daylight is the time that plants feed themselves and grow, thanks to photosynthesis, which only happens during times of light.
By knowing this, we can make some inferences about the effect of light on fruits and vegetables in the fridge. As we all know, it is dark inside the fridge when the door is closed and your groceries are only exposed to light when the door is opened for a brief amount of time. The darkness will make the foodstuffs think it is continually in a state of rest. However, by adding in periods of light within the refrigerator, it will make the produce think it is in the daylight and thus causing them to be active and grow, and in turn, allowing the food to remain fresh and healthy for longer.
This scientific research is relatively recent, but it is definitely something worth looking into. It is certainly possible that future refrigerators will have built in cycles of light and dark to match the circadian rhythms of fruits and vegetables, allowing up to twelve hours of light every day. Similar to every person on Earth, they will wake up during the cycle of light and go to sleep during the cycle of darkness, enabling them to retain their nutritious benefits for longer.
