Oat milk can last up to 10 days in the refrigerator after opening if store-bought. Unopened, it can last up to four months.
Here's a more detailed breakdown:
-
Unopened Store-Bought Oat Milk: Can last for up to 4 months when stored in a cool, dry place. Check the "best by" or "expiration" date on the carton.
-
Opened Store-Bought Oat Milk: Once opened, store-bought oat milk typically lasts for up to 10 days in the refrigerator.
-
Homemade Oat Milk: Homemade oat milk tends to have a shorter shelf life due to the lack of preservatives. It usually lasts for about 5-7 days in the refrigerator.
Factors Affecting Shelf Life:
- Storage Conditions: Proper refrigeration is crucial for maintaining freshness. Keep oat milk consistently refrigerated at or below 40°F (4°C).
- Ingredients: Some brands may add preservatives that extend the shelf life.
- Pasteurization: Pasteurized oat milk generally lasts longer than unpasteurized.
Signs of Spoilage:
- Sour Smell: A noticeable sour or off odor.
- Change in Texture: Thickening, curdling, or separation.
- Discoloration: Any unusual color changes.
- Taste: A sour or unpleasant taste.
Tips for Extending Shelf Life:
- Refrigerate Immediately: Put oat milk in the refrigerator as soon as you open it.
- Store Properly: Store in the main compartment of your refrigerator, not the door, where the temperature fluctuates more.
- Seal Tightly: Ensure the carton or container is tightly sealed after each use.
