Refrigerated reconstituted milk should be used within a few days.
Cans are best stored in a cool, dry area and inverted every 2 months to avoid separation of water and solids, according to the National Dairy Council.
Unopened, they are safe as long as the cans are intact; however, they may thicken, carmelize, and turn brown with time.
These water-extracted milk products, commonly used for cooking and baking, are heat-sterilized and canned for a longer shelf life than regular milk.
Evaporated milk (half the water content removed) and sweetened condensed milk (half of water content removed, then sweetened) have a shelf-life of about 1 year at room temperature.
A can of Acme Beer, packaged with a “church key” pull opener, promised “non-fattening refreshment” that “adds zest to meals”—and offered Rock a peek into alcohol advertising in the 1930s.
And that seemingly unidentifiable battered can Rock uncovered at a Mc Neal Creek homestead?As Jim Rock traveled around the country in the 1980s and 90s, he carried a shiny black suitcase and a stack of 40 notecards.Inside the suitcase were artifacts of a not-long-past era of American industry: metal cans, often dented and rusted, each wrapped carefully in a white wool sock.Once opened, canned milk should be poured into a covered opaque container, refrigerated, and used within a few days.Cans of Nestle Carnation Evaporated Milk carry a "best before" date, and Nestle doesn’t recommend using the product beyond that date for quality reasons.Through careful research on the food companies behind each can, Rock could trace the use of baking powder, a mid-ninteenth-century advancement in baking that provided quick, reliable leavening.
