Understanding food flavor is crucial to effective and strategic research and marketing. Understanding flavor partly involves linking the sensory perception of flavor and its volatile chemical components. Establishing these relationships requires sensory, as well as instrumental analysis, and can be challenging. Two basic approaches for relating data from sensory and

instrumental analyses are discussed. Examples are presented with butter and skim milk powder.
