Scientific studies have shown that light of any kind – whether in the supermarket, refrigerator, kitchen, or through a window – can cause food, beverages, and cosmetic products to degrade faster, often before they meet the expiration date.
With milk and other dairy products, for example, exposure to such light affects its taste, freshness, and nutritional value. Milk contains components that are sensitive to light, including riboflavin, also known as vitamin B2. Light flows right through glass bottles unfortunately.
Researchers at Cornell University found that when fresh milk is protected from light, it holds its flavour and nutritional quality for two weeks. Consumers who tested two-week-old, light-protected milk preferred it over “fresh” milk that had been stored in a typical container and exposed to light for as little as four hours.
Technology to Protect
Noluma International is the first company to use technology developed to assess, measure, and certify light protection in packaging. Its unique, patented technology measures the light protection capacity of packaging as a function of its effects on the product contents.
Noluma’s testing process replicates two weeks of light exposure in just two hours. In fact, Noluma can measure nutrient changes caused by light exposure 99% more efficiently and accurately than conducting a standard evaluation with a panel of expert taste testers. The team can then assess the effectiveness of the packaging, and offer guidance on how to redesign packaging to adequately protect from light damage.
Certify Your Product
Noluma is the only company that certifies products as meeting the highest standards of light protection. A Noluma certification means that a product’s freshness, nutrition, efficacy and sensory qualities will be fully protected from light damage as best as scientifically possible through its packaging for the shelf life of the product.
When consumers see the Noluma logo, they’ll know that the product will not be degraded by light penetrating its packaging, and will maintain freshness and overall quality through the product’s full shelf life – whether edible oils, cosmetics, dairy or other degradable products. They can be assured that the milk they buy will not have been light-damaged, and should have the same taste and nutrients as it did when it was first bottled.
As more consumers become aware of how all kinds of light can degrade the quality and nutrition of the products they buy, they’ll begin to look for light protected packaging solutions that preserve the goodness in the products and brands they love. And the answer is not in a clear glass form.
