Taste worlds of humans vary because of taste blindness to phenylthiocarbamide (PTC) and its chemical relative, 6-n-propylthiouracil (PROP). We review early PTC studies and apply modern statistical analyses to show that a higher frequency of women tasted PTC crystals, and were tasters (threshold classification). In our laboratory, scaling of PROP bitterness led to the identification of a subset of tasters (supertasters) who rate PROP as intensely bitter. Supertasters also perceive stronger… 
Fat Perception is Related to PROP Taster Status
TLDR
The hypothesis that individuals who are PROP tasters have a higher density of fungiform papillae; are more sensitive to capsaicin; and have increased ability to discriminate differences in fat content in salad dressing is tested.
Supertasting, earaches and head injury: Genetics and pathology alter our taste worlds
TLDR
Otitis media and head trauma can alter taste and thus PROP classifications, complicating studies on PROP genetics, and some subjects with a history of otitis media show taste reductions, but others show enhanced tastes and appear to have more taste buds per fungiform papilla.
PROP Taster Status Is Related to Fat Perception and Preference a
TLDR
The hypothesis that fat perception and preference can be linked to genetic and anatomical differences between individuals is supported.
Detection thresholds for quinine, PTC, and PROP measured using taste strips
TLDR
The data suggest that determining taster status for quinine using paper “taste strips”, applied to front part of the tongue, represents a suitable method for the screening for ageusia for bitter taste.
Thermal taste, PROP responsiveness, and perception of oral sensations
TLDR
Examination of ETA-squared values showed that PTS had a greater effect on perceived intensities than did TTS for most sensations, and concluded that pSTs and TTs possess greater responsiveness across a range of taste and trigeminal stimuli and concentrations.
Relation between PROP taster status and fat perception, touch, and olfaction
TLDR
In general, taster status was not related to the perceptions of fat, saltiness, and sweetness, and increasing the flavor levels in the potato chips and mashed potatoes enhanced the perception of fattiness for these systems.
Measures of individual differences in taste and creaminess perception.
TLDR
Comparisons of individual differences in perception of 4 prototypical taste stimuli and PROP under conditions that also enabled assessment of the reliability of individual intensity ratings of taste support other evidence that the genetic factors which determine the ability to perceive PROP do not play a major role in overall taste and oral somatosensory perception.
Individual Variation in PROP Status, Fungiform Papillae Density, and Responsiveness to Taste Stimuli in a Large Population Sample
TLDR
A complex interplay between 6-n-propylthiouracil status and fungiform papillae density and the need of a critical reconsideration of their role in food perception and acceptability is highlighted.
Associations between taste genetics, oral sensation and alcohol intake
TLDR
The results support that variation in oral sensation associates with alcohol intake, and those who taste PROP as least bitter and have low chorda tympani relative to whole mouth taste intensity appear to have fewest oral sensory hindrances to the consumption of alcoholic beverages.
PROP (6‐n‐Propylthiouracil) Supertasters and the Saltiness of NaCl a
TLDR
Taste blindness to phenylthiocarbamide and its chemical relative 6‐n‐propylthiouracil (PROP) was discovered in the 1930s was discovered to be the most intense to supertasters because taste buds in fungiform papillae are innervated by the trigeminal nerve as well as the chorda tympani nerve.

The biological basis of food perception and acceptance
TLDR
For some subjects, even with no stimulation, a phantom taste sensation appeared in the area innervated by the contralateral glossopharyngeal nerve, indicating that when one taste nerve is damaged another compensates; however, the cost may be a taste phantom.
PTC taste blindness and the taste of caffeine
TASTE thresholds for the bitter substance PTC (phenylthiourea or phenylthiocarbamide) and related compounds containing the grouping (HNCS)showa bimodal distribution, leading to the designation
Children's food preferences and genetic sensitivity to the bitter taste of 6-n-propylthiouracil (PROP).
TLDR
Analysis of variance showed significant differences in acceptance of cheese and milk for the two taste groups on one of the three preference tasks, selection of foods in order of preference, suggesting that they like it less or more.
Genetic and pathological taste variation: what can we learn from animal models and human disease?
TLDR
The study of patients with taste disorders suggests that the old tongue maps (e.g. sweet on the tip, bitter on the back) that often appear in textbooks are wrong.
Use and perceived attributes of cruciferous vegetables in terms of genetically-mediated taste sensitivity
TLDR
PTC status, especially in terms of non-tasting propensity, may have some sensory-specific effects which will impact on the use of cruciferous vegetables by young and mature women, but environmental factors may offset this effect and must be considered in studies of food behaviour.
Variations in human taste bud density and taste intensity perception
TLDR
Some variations in human taste sensitivity may be due to different numbers of taste buds among subjects, and the subjects with higher fungiform taste bud densities also reported some tastes as more intense than subjects with fewer fungiform tasted buds.
Increase in taste acuity with sympathetic stimulation: the relation of a just-noticeable taste difference to systemic psychotropic drug dose.
TLDR
A subject’s oral cavity is regarded as a pharmacological test preparation in situ and the taste response as a sensory expression of pharmacological activity.
Facial expressions and genetic sensitivity to 6-n-propylthiouracil predict hedonic response to sweet
TLDR
The results suggest that the sweet liker/disliker distinction is robust and valid, and that sensitivity to PROP may influence preference for sweet by altering the quality of sweet.
Taste and aging.
Taste thresholds are known to rise with age, but the status of suprathreshold sensations is less clear. The present study assessed the perceived intensities of sodium chloride, sucrose, citric acid,
Genetic influences on the selection of Brassica vegetables by elderly individuals
TLDR
The results indicate that other than genetic factors may impede the use of a variety of Brassica vegetables by old women, although the PTC tasters rated the overall flavour intensity of cooked cabbage higher than did the non-tasters.
