It is reported that the plum bean curd contains saponin, a strong stimulus to the digestive tract, can cause hemorrhagic inflammation, and red blood cells have a dissolving effect, as long as the heating to 100 ℃, after a period of time can be destroyed by its toxicity. Bean grains contain hemocyte agglutinin, with hemocyte agglutination.

Plum beans placed too long, but also produce a large number of nitrites, causing degenerative hemoglobinopathy. Therefore, the plum bean curd poisoning due to eating fried, boiled impermeable plum bean curd caused by the rapid onset of its onset, can be a few minutes after eating, most of the 2 to 4 hours.
