Can oranges be eaten if they are blue?

1. If the orange is still a little green, it may be because the orange is not fully mature, but it does not contain toxic substances. You can eat if you want.

2. However, because the sugar in immature oranges is not completely condensed and tastes sour, it is easy to cause certain corrosion and irritation to enamel and gastric mucosa after eating, so it is not recommended to eat too much to avoid discomfort after eating.
