The soymilk box cannot be stored for long at room temperature, only 12 hours at most. In winter, the temperature is relatively low, so it can be stored for the next day, but in summer, it will not work if the temperature is high.

If the soy milk box itself does not have a sour taste, then it means it has gone bad and is not recommended to be eaten to avoid diarrhea. Soybean flour, soy milk, sugar, oil, butter and eggs are used to make soy milk boxes. These raw materials are rich in nutrients, have high water content and are easily infected by bacteria. In addition, there are heat-resistant bacteria remaining in desserts such as soy milk boxes. After such bacteria survive and multiply, they can easily go bad.

In short, the shelf life of soymilk boxes is very short. It is best to buy and eat it now, and to eat it now. If the soy milk box is not placed in the refrigerator, it is best not to store it for the next day. If it is refrigerated, it can be stored for three days.

The main ways to determine whether the soymilk box is broken are as follows:

Look at the product condition. If you see mold growing on the soymilk box or the color has changed, it must have gone bad.

Smell. The soy milk box smells sweet. If you smell anything else, it means it is broken.

Look at the shelf life. There is a shelf life on the soy milk box packaging, and it cannot be eaten after the shelf life.

Taste it. If you eat a soy milk box with a sour taste in your mouth, it means it is broken and needs to be spit out or thrown away.
