A flavoring class (a category entry) that designates the compounds belonging to this class as a group, excluding those generally recognized as highly toxic. The standards for use do not permit use for any purpose other than flavoring.
Under food labeling rules it can be written with the group name “香料” (flavoring), so the substance name rarely appears in the ingredient list.
