It is normal.
Purple sweet potatoes contain a large amount of anthocyanins, which are water-soluble natural pigments that are found in many fruits and vegetables in daily life, such as common eggplants, mulberries, blueberries, grapes, etc. , Anthocyanins are purple or purple-red in an acidic environment, and blue or blue-green in an alkaline environment. Purple potato porridge turns green, which is the change of anthocyanins in an acid-base environment. Don't worry too much. It can be eaten normally.
