1. If papaya is not ripe, it can be eaten raw directly, or it can be used for pickling, stir-frying and cooking soup.

2. The papaya can't be ripened when it is cut and not cooked, because the nutritional value of the melon meat will be lost quickly after it comes into contact with the air. It is best to eat it as soon as possible, and it can be eaten directly raw, but the unripe papaya will be a little bitter when eaten raw.
