Light corn syrup, like Karo® Syrup, is safe to eat for an indefinite period of time, regardless of whether it has been previously opened or not.
While the syrup will not spoil, the quality can degrade over time. For the best possible quality, use the syrup by the "Best by" date printed on the bottle.
Here’s a quick overview:
| Aspect | Detail |
|---|---|
| Safety | Safe to eat indefinitely, whether opened or unopened. |
| Quality | Best quality is achieved when used by the "Best by" date on the bottle. |
| Storage | Store in a cool, dry place. |
Essentially, the syrup won’t go bad in a way that would make it unsafe to consume. However, its flavor and texture might not be optimal past the "Best by" date.
Practical Insights:
- Visual Checks: Look for any signs of mold, unusual odors, or significant color changes, although these are unlikely.
- Taste Test: A small taste test can determine if the syrup’s quality has declined, even after the “Best by” date.
- No Refrigeration Needed: Unlike some other syrups, light corn syrup does not need refrigeration after opening.
Therefore, while light corn syrup doesn't technically "go bad," following the "Best by" date ensures you are using it at its prime.
