White sugar will expire. If white sugar is stored for too long after its expiration date, mites will breed in the sugar.

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.

After people drink sugar water or vegetable juice containing mites, they are prone to stomachache and diarrhea. This situation is more common in the south. In the north, due to the dry air, mites are less likely to breed in white sugar. However, white sugar that has been left for a long time and turns yellow will still breed mites. Eating such white sugar is likely to cause abdominal pain and other physical discomfort.

The wonderful uses of white sugar:

1. Relieve injection pain. When vaccinating, feeding the child some sugar water or putting some sugar on the pacifier will not only reduce the child's crying, but also relieve pain.

2. Disinfect small wounds. Sprinkling an appropriate amount of sugar on small wounds can help kill bacteria near the wounds and have a certain disinfection effect.

3. Eliminate burning sensation. If you are burned while eating, sprinkle some sugar on the tip of your tongue and the pain will subside quickly.

4. Remove stains. Pour some sugar on your hands with soap or hand sanitizer and rub them gently for 20 seconds to remove stubborn stains such as paint and oil stains.

5. Remove odor. Pour the sugar into a paper bag and put it in the refrigerator, which can deodorize and absorb moisture like bamboo charcoal and tea.

6. Extend the flowering period. When flowers bloom, they need to absorb several times more sugar than usual. Therefore, adding some sugar to the vase will help the flowers bloom longer.

7. Keep the cake fresh. Put some sugar in an airtight container where cakes or cookies are stored to extend the shelf life of the food.

8. Natural scrub. A sugar scrub can effectively exfoliate your skin. The specific method is: mix an appropriate amount of white sugar with almond oil or olive oil to form a paste, gently massage the face and body, and rinse thoroughly after washing. If you like the fragrance, you can also add some essential oils.

9. Moisturizing. Mix an appropriate amount of olive oil and white sugar and apply it on your lips. Massage gently to exfoliate your lips and make your lips smoother and moisturized. Applying it on your hands will also have the same effect.

10. Remove the inner skin of chestnuts. Before cooking chestnuts, soak them in sugar water for about 2 hours. After cooking, the inner skin of the chestnuts will be easier to remove.

11. Kill cockroaches. Mix equal amounts of sugar and baking powder evenly and sprinkle into the corners.
