Recently, a consumer experienced large red rashes, cold sweats, headache, chest tightness, confusion, and unsteady gait after drinking undercooked soy milk at a roadside breakfast stall. A doctor diagnosed the symptoms as anaphylactic shock.
Can a cup of soy milk lead to shock? A doctor explains that raw soy milk contains a saponin toxin that can cause nausea, chest tightness, rashes, abdominal pain, and in severe cases, shock, which can even be life-threatening. Additionally, raw soy milk contains an anti-trypsin that reduces the ability of gastric juice to digest protein. Therefore, soy milk must be thoroughly boiled before drinking.
Experts warn that when soy milk is heated to 80°C, it will produce foam, and the amount of foam increases as the temperature rises. Some people mistakenly believe that the soy milk is already fully cooked. In fact, this is just foam from the heating process, and the soy milk has not actually been boiled. Furthermore, do not add raw soy milk while it is cooking. It is best to bring soy milk purchased from the street to a boil before consuming it.
