Half a minute later, Ji Feng looked up and said, "It's indeed poisoning, specifically food poisoning, caused by the use of germinated potatoes in the dish. Germinated potatoes contain solanine, which is an alkaloid found in the green parts of sprouted potatoes. Solanine is a toxic substance, with the highest concentration in potato flowers, followed by stems and leaves, and a lower concentration in the tubers."
"When the solanine content exceeds 20mg/100g, it can be poisonous to humans and animals. Germinated potatoes, because they produce flowers, stems, and leaves, have a dramatically increased solanine content, exceeding the safety index by more than a hundred times. Consequently, consuming them leads to food poisoning, as is the case with them now."
So that's it!
Everyone came to a sudden realization. Although some people knew not to eat sprouted potatoes, they didn't know the specifics.
