The main ingredients of bubble gum are natural rubber and artificial rubber plus sucrose or fructose, rubber plasticizers, synthetic flavors, food colorings, etc. The rubber used was originally sugar gum resin, which is abundant in South America. Now most of it uses synthetic rubber, such as polyethylene derivatives and low-toxicity plasticizers. This kind of edible rubber cannot be digested. substances, but the first-grade white crepe glue used to make bubble gum is added with vulcanization accelerators, antioxidants and other additives. These additives all have certain toxicity, and the state stipulates the allowable daily intake. If children eat too much bubble gum, these toxic substances can cause potential harm to the child. The role of plasticizer in bubble gum is to create bubbles. Generally, 7% plasticizer is required to create bubbles. Although plasticizers have low toxicity, their metabolite, phenol, can be harmful to the human body when reabsorbed in the digestive tract, and plasticizers are used in large amounts. A piece of bubble gum contains 350 mg. If a child eats two pieces of bubble gum a day, he will consume 700 mg of plasticizers. Such a large dose will have an impact on the child's health. It doesn't matter if your child accidentally eats it occasionally. What he eats will not be affected by the digestive juices at all, which means that the body will not absorb it at all, so the bubble gum can only swim once in your stomach and then disappear, just like in your stomach. It's just a tour of the intestinal system. You don't have to worry so much, it'll be fine.
