The increase understanding of the impact of fat on the flavour perception could assist the design of food products that are lower in fat but still rewarding to eat. Here, we mapped the cortical representation to no flavoured fat, flavoured no fat, iso-release and perceived flavoured fat emulsions. We show that the presence of fat in the oral cavity reduces the cortical response to flavour, particularly in the primary taste areas and anterior cingulate, even when samples are iso-perceived (or volatile release) for sweetness, flavour and thickness.
