In a similar way to how clothes fade in the sun, or you can get sunburn, consumer packaged goods are also affected by exposure to all kinds of lights. The effects range from damaging the nutrients in food, to changing its taste or smell.
Beware of light protection claims. Like an SPF, an LPF or light protection factor, that Noluma measures, may be only a 10-15, that still lets light through. Noluma only certifies packaging when LPF is at an effective level to prevent content change.
No. While some packaging may appear to be light protected, only Noluma can guarantee optimal light protection using our patented process which measures how much light penetrates though products packaging and to what degree it impacts the contents of what is inside. Just like an SPF on your sunscreen, we all know that the higher the SPF the better protection you have and that an SPF of 10 does not prevent light damage to your skin. A Noluma certification logo lets you know that packaging is protected at an optimal level that blocks all light and stops light damage to the ingredients and to the sensory characteristics of the brands and products we love. That includes all the important vitamins in our milk.
When exposed to light, after just two hours milk begins to lose Vitamin A. 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 light, you’re getting less of these important nutrients than you would expect.
We are currently in discussions with a number of well-known UK supermarkets and brands. We expect light protected milk to be available very soon in a retailer near you. Watch this space!
Lots of different packaging materials—including paper based cartons and especially glass—can be negatively affected by light. Scientific studies have shown that light can cause food, beverages, pharmaceuticals and cosmetics all to degrade faster.
Noluma is the leader in the light-protection technology for consumer goods and packaging. They measure, assess and contribute to packaging design so that their partner companies can deliver the optimal level of light protection to protect nutrients and taste.
Go the Get Involved page where you will be able to get in touch with your favourite supermarket or milk brand to ask for light-protected packaging for milk.
Absolutely. Light protected packaging materials can be recycled in exactly the same way as other recyclable materials.
Light-protection means that foods stay fresher for longer. In doing so they extend shelf life and freshness of food and other packaged goods. As a result of this light-protection can also reduce overall household food waste.
