Fructose
Fructose is a hygroscopic food, afraid of moisture, heat, and cold. Therefore, it needs to be stored indoors with relative humidity less than 70%, and the surrounding sugar storage environment should not be lower than 0 ℃. Under 0 ℃, sugar will agglomerate due to freezing. In summer, the sugar storage environment should not be higher than 35 ℃. If the temperature is too high, the sugar will melt. Secondly: beside the storage of sugar, it is not allowed to store food that is easy to evaporate or has bad smell.
