Summary

This proposal describes 2 basic research studies that will be conducted sequentially. Study 1 will test the efficacy of both classic and newly developed "generally recognized as a safe" (GRAS) bitter blockers on the perceived bitterness and acceptance of different classes of bitter-tasting compounds by children and compare their responses to adults. Because variations among and between children and adults in terms of sensitivity to different bitter compounds are due in part to genetically determined receptor variation, the investigators will consider genotype when assessing how well bitter blockers perform. In Study 2, the investigators aim to evaluate different methods (forced-choice procedures, hedonic face scales) used for testing children to determine their reliability and reproducibility.
