4.5. Identification of Salt-Liking Phenotypes
Salt-liking phenotypes, including salt likers and salt dislikers, were detected. Individuals who rated liking of all sodium concentrations above the mid-point of the liking scale were identified as “salt likers” while “salt dislikers” rated likings of all solutions below the mid-point. Both salt-liking phenotypes demonstrated a decline in liking as concentrations of sodium increased.The salt-liking phenotypes identified in this study differ from the established sweet-liking phenotypes reported in the literature, e.g., [
