White sugar will expire.

If it is ordinary edible white sugar and uses sucrose as the extract, it will be divided into 18-24 months according to different factors such as outer packaging according to relevant national regulations. In addition, white sugar should be stored away from light and the temperature should be controlled below 20°, so that the sugar can dry for a long time without changing its properties.

White sugar is a good microbial culture agent. As long as the sugar is sealed and stored within the shelf life, it is safe and can be consumed with confidence. However, canned white sugar and bulk white sugar that are not tightly sealed can easily breed mites after being intruded or polluted by humid air. Over time, mites and other bacterial groups will multiply in the white sugar.
