The Umami taste strips are an optional addition to the standard taste strips set. The set consists of four concentrations of the Umami flavor, per concentration you receive 50 strips. So in total 200 strips.
Umami is a Japanese word that means ‘glory’ or ‘savory’; it is one of the five basic flavors, along with salt, sweet, sour and bitter.
Umami taste test
Assessment of gustatory function is a central part of the diagnosis of patients with chemosensory dysfunctions. The taste of monosodium glutamate was described as umami taste a century ago by Ikeda. The aim of this study was to extend a validated gustatory test with 4 concentrations of monosodium glutamate. More information about the background of the umami taste strips can be found in this study: https://pubmed.ncbi.nlm.nih.gov/21774441/
Umami and the complete taste test
When you are using the umami taste strips in the complete taste strips test then please note the following.
When performing the complete taste test, the answers for umami are not taken into account. Only sweet, sour, salty and bitter are scored as described in the instructions. The database is too small to make qualified statements if the answers from umami are added to the score. The additional taste umami is therefore only used as a reference so that this area of taste perception is taken into account, but not included in the evaluation.
Expiration date taste strips
Unopened, the taste strips have a shelf life of 5 years from production. Once opened, the shelf life is limited to 12 months.
