How Can You Tell If Corn Syrup Has Gone Bad?
It is difficult to tell if corn syrup has gone bad as it does not have an expiry date. However, if the syrup develops a sour or off-flavor, becomes cloudy, or appears discolored, it may have spoiled. Additionally, if you see mold growth or presence of any insects inside the syrup, it is a sign of spoilage and the syrup should be discarded.
