Pepper is not spicy in the mouth, because there are taste buds in the mouth, so you can taste spicy. The reason why it feels spicy is not because it tastes spicy, but because the skin on the hands is stimulated, especially for people with delicate skin on their hands. Pepper is spicy because there is a special substance in it, that is, capsaicin, the active ingredient of pepper, which is a kind of pepper. Extremely spicy, after being absorbed by the skin or oral mucosa, it can directly stimulate the sensory nerves of the skin or submucosa, and can produce a burning sensation without taste buds. The most direct way to cut peppers is to put on film gloves or plastic bags to physically isolate your hands from peppers. As long as you don't touch pepper directly, it won't be spicy, so you can nip in the bud.
