Unveiled: the shelf life of oat milk – how long can you keep it?

Oat milk, a plant-based alternative to dairy milk, has gained immense popularity due to its creamy texture and nutritional value. However, like any perishable food, oat milk has a limited shelf life. Understanding how long oat milk lasts is crucial to avoid spoilage and ensure optimal taste and quality.

Unopened Oat Milk

Refrigerated: Unopened oat milk stored in the refrigerator can last for **7-10 days** after the printed “best before” date. The cold temperature inhibits bacterial growth, extending its shelf life.

Unrefrigerated: Unopened oat milk can be stored at room temperature for **2-3 months**. However, once opened, it must be refrigerated immediately.

Opened Oat Milk

Refrigerated: Once opened, oat milk should be consumed within **5-7 days**. The exposure to air and increased temperature accelerates spoilage.

Signs of Spoiled Oat Milk

• Sour smell: A sour or unpleasant odor is a clear indication of spoilage.
• Lumpy texture: Spoiled oat milk may develop lumps or a grainy texture.
• Mold: Visible mold on the surface of the milk should immediately be discarded.
• Off-taste: If the oat milk tastes bitter, sour, or rancid, it is not safe to consume.

Storage Tips for Oat Milk

• Refrigerate immediately: After opening, refrigerate oat milk promptly to slow down the growth of bacteria.
• Store in a sealed container: Transfer any remaining oat milk to an airtight container to minimize air exposure.
• Use a clean spoon: Use a clean spoon or utensil to avoid introducing bacteria into the oat milk.
• Discard spoiled milk: If any signs of spoilage appear, discard the oat milk immediately to prevent consumption of harmful bacteria.

Understanding the Shelf Life of Oat Milk

The shelf life of oat milk is influenced by several factors:

• Packaging: Oat milk packaged in aseptic cartons has a longer shelf life than those in plastic jugs.
• Ingredients: Oat milk with added preservatives may have a slightly extended shelf life.
• Storage temperature: Maintaining a consistent cold temperature in the refrigerator is essential for preserving oat milk’s quality.

Tips for Extending the Shelf Life of Oat Milk

• Freeze oat milk: Freezing oat milk can extend its shelf life by several months. Thaw it in the refrigerator before use.
• Make your own oat milk: Homemade oat milk has a shorter shelf life but can be customized to your taste preferences.
• Use oat milk in smoothies and baked goods: Incorporating oat milk into smoothies and baked goods can help consume it before it spoils.

When in Doubt, Throw It Out

If you are unsure whether oat milk is still good, it is always better to err on the side of caution and discard it. Consuming spoiled milk can lead to foodborne illnesses.
