Does sugar go bad if left open?

Of course, you can't store sugar in an open container without some form of air to keep the granules from sticking together. The answer is yes, sugar can go bad left open in a dry place. The dry air will cause the crystallized sugar to form lumps. This lumpy sugar is called granular crystallization. Individual granules of sugar will still be edible, but they will be hard and crunchy.

Can sugar go rancid if left open?

The truth is, sugar does slowly go bad when left open, but it’s not in the way you might imagine. When sugar is left open, it begins to break down by a process called caramelization. This process slowly and inevitably converts the sugar into a thick, gooey syrup. It’s not a bad taste, but it does mean that the sugar will no longer work as a sweetener.

Can you store sugar open?

The short answer is yes, but it depends on how long it’s left open and the sugar type. Granulated sugar, for example, can lose moisture if stored open, but it does not go bad. Powdered sugar will start to clump if left out too long. Storing sugar in an airtight container will help reduce moisture loss.

Can you eat sugar open?

It’s hard to imagine leaving sugar out on the counter in your kitchen, especially after seeing all of the recent headlines about how sugar can be bad for you. As long as the sugar is in its pure form, it should be fine left open. However, if it becomes granulated, it can sometimes cause your home to smell funny and possibly develop an unsavory taste.

Does sugar go bad if it's left open at room temperature?

Even if you keep sugar in a tightly sealed container, left open, it will still eventually absorb moisture and crystallize. This crystallization process can happen very quickly at room temperature if the sugar is exposed to moisture, so it's best to store sugar in a dry place. That being said, room temperature is not a high enough temperature to cause sugar to crystallize on its own, so it will not go bad if left open.
