The pantry is a treasure trove of essential ingredients, and evaporated milk is one of those staples that can elevate a variety of dishes from soups to desserts. However, like all dairy products, evaporated milk has a shelf life and can expire. The question on many minds is whether expired evaporated milk can make you sick. To answer this, let’s delve into the world of dairy, expiration dates, and food safety.
Understanding Evaporated Milk and Its Shelf Life
Evaporated milk, also known as dehydrated milk, is made by removing about 60% of the water from regular milk. This process concentrates the milk’s nutrients and extends its shelf life, making it a convenient ingredient for cooking and baking. Evaporated milk is packaged in cans or aseptic cartons and, when stored properly, can last for several months to a few years, depending on the packaging and storage conditions.
