Additional work may also be done by the flavor company. For example, the flavor company may conduct sensory taste tests to test consumer acceptance of a flavor before it is sent to the client or to further investigate the "sensory space". The flavor company may also employ application specialists who work to ensure the flavor will work in the application for which it is intended. This may require special flavor delivery technologies that are used to protect the flavor during processing or cooking so that the flavor is only released when eaten by the end consumer. The flavor obtained is determined not just by the simple presence of a flavorant or a mixture of flavorants, but also by their concentrations. Thus, even if a non-flavored ingredient is added/removed to/from a food or beverage, this can noticeably affect the final flavor if it dilutes or otherwise changes the concentrations of the remaining flavored ingredients.
