3 reasons why light protection is important for food and nutrition

April 18, 2019

Light. It’s a crucial part of life. Yet too much light can have a damaging effect. We all know that it can damage your skin and fade your clothes but did you know that it can affect the taste, nutrition and flavour of some of the food and drink we love.

The effect of light on food and drink has been of increasing interest to scientists. Recent studies have looked at milk and discovered that when it is exposed to indoor light (what you might know more commonly as LED and artificial lights) the following changes can take place:

  1. It gets less tasty Taste is very personal and certainly not everything tastes the same to each or us. But we can all tell when something tastes or smells off. A recent scientific study found that when milk was exposed to light for just 15 minutes a panel of sensory experts noticed a change in its flavour. And after just 48 hrs of light exposure, the flavour worsened with tastes and smells you would normally associate with milk being off.
  1. It goes off faster Light impacts the nutrients and the makeup of milk in such a way that it encourages molecules to break down faster and more easily. It sounds complicated but essentially what this does is speed up the process of how milk starts to go off. The best way to stop light damaging milk is simple – keep it in the dark. The easiest way to do this is by buying milk in light-protected packaging. What we at Noluma are championing! Learn more here.
  1. Nutrients are reduced When exposed to light, after just two hours milk begins to lose Vitamin A. And after 16 hours, less than half the Vitamin A remains. Light also damages key nutrients including Vitamin D and B12, also known as Riboflavin. So when you drink milk that has been exposed to indoor and refrigerator light, you’re getting less of these important nutrients than you would expect.

What’s the answer? Here at Noluma we are passionate about protecting food and drink from the damaging impact of light. As the leaders in light-protection technology we measure, assess, certify and help companies deliver the highest levels of light-protection. A Noluma logo certifies that packaging meets the gold standard for light protection and the product inside it has the quality, freshness and nutritional qualities it promises. Be aware that not every light protection claim can protect nutrients.  Just like an SPF of 10-15, low packaging light protection does not do much to protect.  Noluma only certifies packaging whose Light Protection prevents content change due to light.

So what can you do about it?

We would love for you to come on this journey with us to protect the nutrients in the milk we all love. To do that simply click here and let your supermarket or favourite milk brand know that you want your milk protected from light.
