Technically, olive oil which has had herbs or fruits infused in them cannot be called olive oil. See the definition for olive oil above. According to IOOC regulations it must be called "fruit juice". In reality, few producers comply with this and you will see labels such as "lemon infused olive oil" or "basil olive oil". Because of their immense popularity, the California Olive Oil Council is trying to come up with a meaningful labeling standard for flavored oils.
