Yes, open coconut water does go bad.
After opening, coconut water is susceptible to spoilage due to microbial activity. Refrigeration slows down this process, but it doesn't eliminate it entirely.
Here's a breakdown:
-
Refrigeration is Key: To prolong its freshness, you must refrigerate open coconut water immediately.
-
Shelf Life: When properly refrigerated, open coconut water typically remains good for up to 5 days.
-
Signs of Spoilage: Discard coconut water that exhibits any of the following:
- Sour or off odor: A noticeable unpleasant smell.
- Change in taste: A sour or fermented flavor.
- Discoloration: Any unusual change in color.
- Slimy texture: A thickened or sticky consistency.
-
Unopened Coconut Water: Unopened coconut water, stored properly (usually at room temperature until opened), will last until the expiration date printed on the packaging.
-
Why It Goes Bad: Coconut water contains natural sugars and nutrients that microorganisms can feed on. Once the container is opened, these microorganisms enter and begin to multiply, leading to spoilage.
In summary, consume open coconut water within 5 days of opening, provided it's refrigerated and shows no signs of spoilage.
