Arla develops non-UHT long-lasting milk

Milk is being made to stay fresher for longer thanks to technology first pioneered by the creators of ice beer, the BBC reports. Scandanavian dairy giant Arla Foods launched recently 'PurFiltre' milk, a milk designed to last for up to three weeks. The new product is made using a ceramic filter that removes the bacteria that turn milk sour while leaving all of the milk's natural vitamins and minerals intact. The milk is then pasteurised in the normal way before being bottled, lasting more than twice as long as its traditional counterpart. The filtration technology was first developed to brew the new generation of fashionable ice beers. Up until now the only way of making milk stay fresh for longer has been the high heat treatment associated with UHT milk. The harmless lactic acid bacteria, that cause milk to sour, survive normal pasteurisation but are removed by the new filter process. This new product is due to hit the UK supermarket shelves next week.
