Do you need to blanch long beans when stir-frying them?

Long beans, also known as cowpeas in our daily lives, are a very common type of beans in our lives. Many people like to eat long beans very much. However, when cooking, I am worried that there are toxins in the long beans, which may cause poisoning if not cooked thoroughly. So, is it necessary to blanch long beans before stir-frying to make them cook faster and reduce the residual toxins?

1. Do you need to blanch the cowpeas before frying them?

If you boil the beans and add some salt, they are easier to cook and not undercooked, because salt is added during boiling, which makes them more flavorful, especially green beans, which have some toxins. They need to be fried until 90% cooked before eating, which is healthy! But I usually don't boil them, just blanch them directly and fry them for a longer time!

In addition, it is best to blanch the beans in advance, add a little vinegar when blanching, and remember to quickly rinse with cold water after blanching, so that the fried beans will be emerald green.

Like other legume vegetables, beans contain saponins and lectins. These two substances have a strong stimulating effect on the gastrointestinal mucosa, and have destructive and hemolytic effects on cells. In severe cases, hemorrhagic inflammation can occur. These two poisonous substances are not heat-resistant and can be destroyed after being fully heated. The main way to prevent bean poisoning is to stir-fry and cook the beans thoroughly before eating. When processing the beans in a large pot, you must pay attention to stir-frying evenly and cooking them thoroughly so that the beans lose their original green color and bean smell.

Many legume vegetables contain a protein that can cause red blood cells to agglutinate, called lectin. Eating raw soy foods containing lectins can cause symptoms such as nausea and vomiting, and in severe cases can be fatal. However, lectins can be destroyed during heat treatment, so green beans, lentils, and beans should not be eaten raw. However, peas do not contain this hemagglutinin and can be eaten raw. If you can't tell the difference, avoid eating raw beans.
