These taste strips reliably identify the tasters and non-tasters and are completely safe, as PROP is only present in micrograms per strip. Ideal for research studies and for demonstrations in the classroom. One package tube consists of PROP taste strips. The shelf life of the strips is approximately months after production. If you taste nothing but paper, you are a non-taster.

Edible strips that contained or nanomoles of PROP were prepared for psychophysical studies. All psychophysical data were subsequently analyzed as a function of TAS2R38 genotype. The use of PROP strips for distinguishing between individuals with at least 1 PAV allele and individuals with other genotypes was assessed and compared with the use of PROP solutions for making this same distinction. Furthermore, individuals with 2 AVI alleles responded to 0. In general, those with at least 1 PAV allele rated the bitter taste of PROP as unpleasant in both delivery methods strips or solutions.
Are you a supertaster: How does PROP taste to you?
History[ edit ] The term originates with experimental psychologist Linda Bartoshuk , who has spent much of her career studying genetic variation in taste perception. In the early s, Bartoshuk and her colleagues noticed some individuals tested in the laboratory seemed to have an elevated taste response and took to calling them supertasters. Phenylthiocarbamide[ edit ] In , Arthur L. Fox, a DuPont chemist, discovered that some persons found phenylthiocarbamide PTC to be bitter while others found it tasteless.
A few posts back I wrote about the discovery that some people can taste the bitter chemical PCP and some cannot. When researchers study taste sensitivity, they prepare glasses of water with increasing concentrations of PROP. By starting with plain water and progressing to denser solutions, they determine the threshold at which you become sensitive to the bitter taste. You can purchase test strips online from the Supertaster Test website.
