I did some research & I think I’ve answered my own question..... While food processors must list all of the ingredients on a food label, flavor manufacturers do not have to disclose their ingredients. They can add synthetic solvents, preservatives, emulsifiers, carriers and other additives to a flavor that qualifies as natural under current regulations. Natural flavors allowed for use in certified organic foods are subject to a DIFFERENT, far more restrictive set of regulations. They cannot contain a long list of ingredients, including synthetic solvents, carriers and emulsifiers or artificial preservatives. They must use non-petroleum-based solvents, cannot be irradiated and cannot use flavor extracts derived from genetically engineered crops....... So, according to this information “natural flavorings” are permitted on Whole30 only in certified organic foods, ..... the corn in Pace is probably from its natural flavoring.
