Study Summary

Ketone ester (KE) drinks are sold commercially in the USA and elsewhere (the FDA has accepted a GRAS (generally regarded as safe) notification on the KEs we propose to study). KE drinks can have beneficial effects on metabolism. Unfortunately, KE drinks have a strongly unpleasant flavor which can trigger rejection. The current study will generate data to help inform KE drink formulations with improved flavor. First stage, trained subjects will rate the intensity of various sensation qualities (e.g., bitter, sour, metallic, and astringent) from KE drinks to help understand the nature of the unpleasant flavor and the particular sensory systems involved (e.g., taste vs. smell). Then, subjects will taste KE drinks with and without various flavor modifiers. Subjects will be healthy adults (aged 21-45) without known food allergies.

Primary Outcome

Rated intensity of taste qualities (e.g., sour, bitter) and mouth-feel (astringent) of model drinks, measured using the general Labeled Magnitude Scale (gLMS). In this implementation of the gLMS, scores will range from 0 (or "no sensation") up to 100 ("strongest imaginable sensation"), with higher scores indicating stronger perceived intensity for the sensation in question.
