This morning , as soon as I woke up, my mother hurriedly took my cup to make me honey water.

When my mother came back after pouring the water and took the honey bottle to pour honey into the cup, I suddenly found that the lower part of the honey was very white, as if it had a lot of hair. I shouted loudly. She shouted: "Mom, the honey has grown hair. Is it expired and can't be drunk? It should be thrown away!" Mom also said in surprise: "Yes! But I just bought it not long ago, it shouldn't be It’s broken.” I thought strangely: If it’s not broken, what’s wrong?

In the evening, after I finished my homework, I checked online with my mother, and I saw it on the Internet. : This is the crystallization phenomenon of honey, which is a physical change and is natural and normal. The main cause of crystallization in honey is the glucose in honey. The main component of honey is sugar, which accounts for 3/4 of the total components of honey, and the water content is less than 1/4. Glucose and fructose account for 80-90% of total sugar. Since glucose is easy to crystallize at low temperatures, after honey is placed at a temperature below 20 degrees for a period of time, the glucose will gradually crystallize, resulting in honey crystallization.

Oh, that’s it! I took out the honey bottle and observed it carefully, and also turned the honey bottle upside down. The whitened honey could no longer flow, but stuck firmly to the Underneath. I realized that the honey was really not bad, but crystallized. I remembered something from the past. I had seen water freeze into ice at low temperatures. Now I know that honey can actually crystallize at low temperatures. Honey that can crystallize is good honey and pure honey, and crystallized honey is easier to store!

Children, if your honey also grows "white hair", you must Don't make a fuss, that's honey crystallized. If you carefully observe the crystallized honey, you will also learn a lot!
