Does Evaporated Milk Go Bad?

Quick Links :

Evaporated milk is a type of milk that has been sterilized by heat to remove about 60% of its water content, resulting in a creamy, rich texture. It is a popular ingredient in many recipes, particularly in baking and cooking. However, like any dairy product, evaporated milk can go bad if not stored properly or if it is past its expiration date. In this article, we will explore the shelf life of evaporated milk, how to store it, and signs of spoilage.

Shelf Life of Evaporated Milk

The shelf life of evaporated milk depends on various factors, including the storage method, packaging, and handling. Generally, evaporated milk can last for several months to a year or more when stored properly.

Unopened evaporated milk can last for:

• 6 to 12 months in the pantry or cupboard
• 1 to 2 years in the refrigerator
• 2 to 3 years in the freezer

Once opened, evaporated milk should be consumed within:

• 3 to 5 days in the refrigerator
• 1 to 2 months in the freezer

It's essential to note that evaporated milk can go bad if it is not stored in a clean and airtight container. Always check the expiration date and the packaging for any signs of damage or leakage before consuming.

Factors Affecting Shelf Life

Several factors can affect the shelf life of evaporated milk, including:

• Storage temperature: High temperatures can cause evaporated milk to spoil faster.
• Storage method: Evaporated milk should be stored in a clean, airtight container to prevent contamination and spoilage.
• Packaging: Evaporated milk packaged in cans or aseptic containers can last longer than those packaged in cartons or bottles.
• Handling: Evaporated milk that is handled roughly or exposed to light can spoil faster.

Signs of Spoilage

Evaporated milk can go bad if it is not stored properly or if it is past its expiration date. Here are some signs of spoilage to look out for:

• Off smell: If evaporated milk has a sour or unpleasant odor, it may be spoiled.
• Slime or mold: Check for any visible signs of slime or mold on the surface of the milk.
• Slimy or curdled texture: If evaporated milk has a slimy or curdled texture, it may be spoiled.
• Expired date: Always check the expiration date on the packaging. If it is past the expiration date, it's best to err on the side of caution and discard it.
