Children and teenagers require 40% more sucrose in a in a solution for them to detect the taste of sugar, a study published in journal Nutrients revealed.
Along with higher taste-detection thresholds, both children and adolescents prefer significantly more concentrated levels of sweetness than adults, the researchers concluded.
"Both of these dimensions of sweet-taste perception sensitivity and preference undergo distinct developmental trajectories from childhood to adulthood," said M. Yanina Pepino, a professor of food science and human nutrition at the University of Illinois, Urbana-Champaign, who co-wrote the study. "However, they did so independently, and we found no association between the two."
Participants in the research included 108 children, 172 adolescents and 205 adults, who ranged in age from 7-67.
Sweet taste sensitivity doesn’t predict preference
The researchers gave participants different pairs of sugar-water concentrations to taste and measured both the concentration that participants preferred and the lowest concentration at which they could detect the taste of sugar.
"While children's lower sensitivity required higher sucrose concentrations for them to detect the taste, participants' sweet-taste sensitivity did not predict the level of sweetness they preferred," said co-author Julie Mennella of the Monell Chemical Senses Center.
"To illustrate these age-related differences in taste sensitivity, we estimated the number of 8-ounce glasses of water in which 4 grams of sucrose - the equivalent of one sugar cube - could be dissolved and participants in each age group could start detecting the sweet taste."
