Corn syrup is one of the most widely used liquid sweeteners in the food industry. It is made by breaking down corn starch using an enzyme reaction.
Does Corn Syrup Go Bad?
Technically speaking, any food items can go bad once bacteria grow on it and leaves behind its toxins. Some foods, like corn syrup, are very resistant to this since bacteria have a hard time multiplying in a sugary environment without much water. The main culprit of corn syrup going bad is if it is stored improperly.
How To Tell If Corn Syrup is Bad?
The two main things to look out for are the color and the smell. If the smell is off, then discard the corn syrup right away. One thing to note is that the corn syrup turning yellow over time doesn't mean that it has gone bad.
How Long Does Corn Syrup Last?
When stored properly, corn syrup can last for many years if it is not opened. Most corn syrup is safe to eat indefinitely, but again, if it fails the test of color and odor, discard the corn syrup.
The best by date is the date that the corn syrup will retain its flavor. After that, corn syrup may not taste as good as it was intended, but it doesn't mean that it is not safe to eat.
If the corn syrup is opened, it will last up to 6 months without spoiling.
How to Store Corn Syrup?
Corn Syrup storage is very easy. It can be stored at room temperature and away from sunlight. This means that any typical kitchen setting is suitable.
There is no need to refrigerate corn syrup after it is opened. It will stay good for up to 6 months.
