Saliva and Sweet Taste Perception for Phenylthiourea (P.T.C.)

Abstract

SummaryTaste sensations for P. T. C. and the standards might occur when an aqueous solution of a solid is placed on a tongue, free from the saliva of the parotid, sublingual and submaxillary glands, the tongue thus being soaked only by the secretion of v. Ebner's glands and other small glands on the tongue.A descending paper chromatography method described in the paper failed to reveal any different influence of the saliva from different persons (non-tasters, tasters and a sweet taster) on phenylthiourea.
