The kidney bean, also known as lentil, can cause human poisoning mainly because it contains natural toxins such as saponin and haemagglutinin. Saponin is contained in pods, which has strong irritation to human digestive tract mucosa and can cause gastrointestinal symptoms. Hemagglutinin is contained in beans, which has the function of coagulation and can cause severe vomiting.
The prevention of lentil poisoning is very simple, as long as the lentil is cooked thoroughly, the toxin can be destroyed. When boiling with water, lentils need to lose their original green, stiff and beany taste. When frying lentils, the amount of each pot should not exceed half of its capacity. Stir-fry the lentils in oil, add some water, cover the pot, and simmer for 10 minutes at 100 100℃ for a uniform heat, turning the lentils with a shovel. In addition, when purchasing tender lentils, it is better not to buy or eat old lentils. Before processing, it's best to remove the tip and filament of lentils and soak them in water for 15 minutes.
