2. Today, the uncles and aunts of Lucheng District Food Safety Supervision Administration came to give us a food safety lesson. I saw my aunt give us five or six cups and test tubes each. These things are sacred and inviolable, as if they really compete with the safety of these foods.
Aunt taught us to cut the food into small pieces, put it in a test cup, pour half a glass of water, and then soak it for ten minutes. In order not to waste time, let's go on to class.
4. "Students, what do you think food is?" I thought to myself, "Food is edible". Some people say "something to eat", while others say "something eaten raw or cooked". Then my aunt put it in the next picture, with six striking characters: Top Ten Junk Foods. I'm a little scared. I often eat something!
The top ten junk foods are: processed food, fried food, carbonated drinks, biscuits and ice cream. These top ten junk foods are harmful to human health. After reading these announcements, I am a little worried. Will it affect my health?
6. Auntie told us not to go shopping in undocumented places, such as small shops next to the school, and it is better to go shopping in big shopping malls.
7. The next step is to test whether the things in your house are safe. I smell the fragrance of mushrooms and see the red color of Lycium barbarum. I don't know where "unsafe" is hidden and where "safe" is hidden. Aunt asked us to stir first, then extract some water from the test tube, and then let other uncles and aunts help us drop "fast food safety reagent".
8. First extract the mushrooms. I don't know what will happen. After a while, the water in the test box changed from clear water to striking purple, which suddenly made people feel scared. I then tested Lycium barbarum, and it didn't change color after a few minutes, which indicated that it was safe. After testing all foods, except Lycium barbarum, all other foods are unsafe! At night, I have to tell my parents that those foods are unsafe, so don't buy those unsafe foods in the future.
Today's lesson made me understand that food safety is very important, not only harmful, but also harmful to people's health, which benefited me a lot.
