Fat may influence taste by a combination of two mechanisms, both of which
have been proposed to explain the effects fat has on taste (Lynch ef al. 1993;
Shamil ef al. 1992; Yamamoto ef al. 1999). First, fat may form a barrier
between the taste compounds and taste receptors, resulting in a decrease in
perceived taste intensity. Second, fat may increase the concentration of watersoluble
taste compounds in the aqueous phase, creating a more intense
perception of taste.
