Milk is considered to be a highly nutritious liquid, because it is high in a range of nutrients. But it is loosing its properties because of New energy-saving LED lights which is killing the vitamins of milk which are been sold by supermarkets just to attract and make an immediate impression upon customers.
The report Milk: Light exposure and depletion of key nutrients, which is a review of the available scientific literature, shows that high-intensity lighting, such as that found in supermarket dairy cabinets, reduces essential nutrients found in milk, such as Vitamin A, Vitamin B2(riboflavin) and Vitamin D. These nutrients are important components of a healthy diet, helping to prevent disease and support growth, but most consumers are unaware that light can significantly impact milk quality, taste and its beneficiality.
It is been found that After two hours of exposure of milk to the LED lighting at supermarkets begins to lose vitamin A. After 16 hours, it has half the amount expected. The report also shows that riboflavin can decrease by 28 per cent after just 20 minutes of indoor light exposure and after around half of all milk remaining on display for at least eight hours on retail shelves is at risk of light damage if it does not have any form of light-protected packaging.
According to Dr. Catherine Birch, Newcastle University, School of Natural and Environmental Sciences, told the press: ‘While milk is just one component of a healthy diet, it is an important one, providing people with many essential nutrients including vitamins, protein and minerals. Many people do not realise that exposure of milk to indoor light can have a detrimental effect. The damaging effects of light can be influenced by the light intensity and time of exposure, so longer exposure to light causes milk to deteriorate faster.’
The trade association said this view had been confirmed in tests by Public Health England, which determines what nutritional information is displayed on milk and other products.
There are solutions to this issue which includes packaging which is designed to be light-protected as technology is available to design containers that reduce or prevent light damage.
