Thing is, it’s often hard to tell what they’ve actually included under the vague heading of natural or artificial flavoring, because the ingredients that make up different tastes are mostly secret, closely guarded by the companies that manufacture them.
Flavor or flavour (see spelling differences) is the sensory impression of food or other substance, and is determined primarily by the chemical senses of taste and smell. The "trigeminal senses", which detect chemical irritants in the mouth and throat as well as temperature and texture, are also important to the overall Gestalt of flavor pe****tion. The flavor of the food, as such, can be altered with natural or artificial flavorants which affect these senses.
