Make good use of it. Pearl is generally ripe, because it is a natural organic matter, which contains certain nutrients such as protein, minerals and trace elements, but also contains some harmful substances, such as heavy metals. If eaten raw, it may have a certain impact on human health. So generally speaking, pearls need to be processed before they can be eaten. Common pearl processing methods include boiling, stewing and frying. These processing methods can effectively remove the harmful substances in pearls, while retaining the nutrients in pearls. In addition, pearls can also be used to make pearl powder, pearl cream and other health care products and cosmetics, which can only be used after processing. Therefore, it is suggested that pearls should not be eaten raw, but cooked or processed.
