After the pumpkin seeds are dried in the sun, the skin is soft, and it is easier to peel off because it is separated from the nuts inside. Peel with your hands when peeling, and don't bite with your teeth like melon seeds. If you bite with your teeth, a lot of saliva will stick to the melon seed skin and be lost, which will easily cause excessive internal heat and oral ulcer. Of course, some troublesome people choose to take the skin and chew it before eating. In fact, the skin of pumpkin seeds is not easy to digest, so it is better to eat it without skin.
