Scientists may have found a way to extend the shelf life of milk to two months
Milk, the first thing mammals consume after birth, is full of protein, vitamins, and minerals. But it doesn’t keep very long. That’s because raw milk is also full of bacteria. How long it stays fresh depends on how it’s treated. Most supermarket milk has been pasteurized and if unopened can keep in the fridge for around a week. Milk that is heated to temperatures above 135ºC (275 °F) can keep as long as six months at room temperature if unopened. But ultra-high temperature milk doesn’t taste very good.
