So vegetarians have no clue whether a flavour contains fish, poultry, beef or pork. A Tomato Soup with Natural Flavours is not necessarily a vegetarian delight. Ten years ago they changed the cooking medium to vegetable oil but the natural flavour in the fries is still from animal products . Natural smoke flavour is a bottled flavour. Some fast food chains serve grilled chicken sandwich with beef extracts.
Artificial flavours are what they say they are credit the food industry with a bit of honesty here.
A typical artificial strawberry flavour contains 49 chemical compounds. No manufacturer of cooked meat products tells us what parts of the animal are used and how much. There is only a blanket description offal . You could be eating unexpected parts of an animal. One can now appreciate the Vegetarian Wine label.
