One common feature in all refrigerators all over the world is the white interior, which plays a key role in the functionality of home appliances.
Notably, white interiors have been adopted by all manufacturers over the years, especially in the 1950s when many households in Europe were adopting food-preserving technology.
Some manufacturers have also settled on shiny reflective interiors for the interior of deep freezers.
However, despite the differences, the interior plays the same role that entails reflectivity, hygiene and temperature control.

One of the main reasons why fridge interiors are white is because white surfaces are reflective when light hits them.
This comes into play when the fridge is placed in a dark room or during the night.
While all fridges have an inbuilt light that turns on when the door is opened, one can see through all corners and access food as the white interiors reflect the light.
Manufacturers often choose white interiors primarily for hygiene purposes.
It is easy to spot dirt and food spillage on a white surface as compared to a dark shade surface. This, therefore, makes it easy for an owner to know what sections of the fridge need to be cleaned.
Maintaining hygiene in a fridge is notably important due to the potential risks associated with poor hygiene, such as the threat of bacterial infections.
Some of the products that can be used in cleaning a fridge include liquid soap and vinegar.
Additionally, white interiors convey an impression of cleanliness, which can be reassuring to customers.
White surfaces reflect heat rather than darker colours, contrary to black ones.
Given its function of preserving food items, the interior of the fridge has to be at low temperatures at all times to prevent any bacteria from developing in the food.
Eating infected food can lead to diarrhoea and vomiting, according to health experts.
“The refrigerator comprises of a thermally protected compartment and a warmth siphon that moves energy from within the chiller to its outside condition so that within the refrigerator is cooled to a temperature beneath the room temperature.
“The lower temperature brings down the generation pace of microorganisms, so the refrigerator lessens the pace of waste. Consequently, a refrigerator keeps up a temperature a couple of degrees over the point of solidification of water,” Eco-Fridge, a UK manufacturer company, explained on its website.
