Robert Marshall, University of Missouri Professor says buy milk placed in the dark corners. Does your milk taste like wet cardboard? Blame the bright lights in your market's dairy section. Robert Marshall, University of Missouri food science professor said milk when exposed to fluorescent light has a bitter taste. If the milk is stored within a few inches of fluorescent light in translucent shelves, has an oxidized flavor within a few hours and distinct off flavor after 12 hours. Marshall the closer the milk stays to the lights and longer it stays there it creates an off flavor which other experts also call it as "burnt" flavor. The good news is these lights have little effect on milk's nutritional value and is not related to bacteria, however fluorescent light inactivates riboflavin (vitamin B2) and ascorbic acid (vitamin C). The researchers say Whole milk variety suffers the least compared to other low percent and low fat milk varieties. The high level of fat present in whole milk blocks out the damaging light wavelengths, but other milk varieties will lose its flavor when exposed to fluorescent lights. Milk in glass and translucent plastic containers are affected quickly with fluorescent light, while opaque paper board containers prevents this off flavor problems, the best. Marshall recommends buying milk from the deepest corners where the milk receives less light, but definitely not from the front rows. I think the groceries stores and marketplaces should start using LEDs which doesn't seem to affect the food and keeps the foods fresh a longer time. The LED's doesn't emit ultraviolet or infrared lights which are harmful and spoils the foodstuffs. One supermarket place, Migros in Switzerland is incorporating this, since the local superstores are not doing this, we better take the milk from the back rows not the front ones. Or go to the farmer's market and get fresh milk.
