Corn syrup is a sugar syrup that's made from, you guessed it, corn! It's a popular ingredient in baking and cooking, and it's known for its thick, gooey texture. But, what makes it so resistant to spoilage? Well, it's all about the chemistry, baby!
The high sugar content in corn syrup makes it difficult for bacteria and mold to grow, kind of like how a desert environment makes it hard for plants to thrive. And, because corn syrup is a hygroscopic liquid, it can absorb moisture from the air, which helps to prevent the growth of microorganisms. But, don't think that means you can just leave it out forever!
In fact, while corn syrup doesn't need to be refrigerated, it's still a good idea to store it in a cool, dry place, like a pantry or cupboard. This will help to prevent the growth of crystals, which can form when corn syrup is exposed to temperature fluctuations. And, if you're planning to use your corn syrup within a few months, you can probably get away with storing it at room temperature.
