Description

The ODOFIN taste strips are a validated examination procedure to investigate the taste ability. This is the complete kit which can be used to test the taste ability of 50 people.

When testing the whole-mouth smell ability, the taste strips are applied by putting them on the tongue and closing the mouth (the patient may move the tongue). If there is interest in the gustatory sensitivity of certain tongue areas (e.g. lateralised testing), the mouth stays open and the strip will only be in contact with this area until the patient can give an answer.

ODOFIN Taste Strips for taste testing

The complete set consist of 16 containers with 4 concentrations of sweet, sour, salty, bitter each and 3 containers with blank strips. The complete set includes 19 containers with 50 strips each, i. e. 950 strips in total. it will be delivered in a box with a English (or German) manual. This kit can be used to test 50 persons.

Expiration date taste strips

In the manual of the taste strips the following is said about the expiration date:

The inside of the cardboard lid, which contains the tasting strips cans, and each tasting strip is marked with a best before date. Unopened, the tasting strips have a shelf life of 5 years from production. Once opened, the shelf life is limited to 12 months. Enter the period of the first opening, on the symbol located inside the box lid.

For the shelf life, Burghart is mentioning this publication.

Optional: Umami taste strips

The Umami taste strips are an optional addition to the standard strips. The set consists of four concentrations of the Umami taste, 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.

Background information

Taste strips are filter paper strips impregnated with taste solutions representative of 4 basic taste qualities at 4 different concentrations (sweet: 0.4, 0.2, 0.1, 0.05 g/mL sucrose; sour: 0.3, 0.165, 0.09, 0.05 g/mL citric acid; salty: 0.25, 0.1, 0.04, 0.016 g/mL sodium chloride; bitter: 0.006, 0.0024, 0.0009, 0.0004 g/mL quinine-hydrochloride), which have been validated for the use in both adults and children. The method is well accepted especially by children and adolescents and has been used in several clinical and research contexts.

The results of this test reflect a measure of the ability to identify 4 basic tastes. The test-retest reliability compares well with other taste tests. During this test, a strip is placed at the middle of the anterior tongue and the participant is to report the taste perceived (salty, sour, sweet, bitter, or nothing) by pointing at the corresponding word on a response chart. To familiarize participants with the procedure and to test whether they were able to identify the different tastes correctly, strips with the highest concentration of each taste (taste high) were presented at the beginning of the paradigm in random order. Participants were asked to identify the taste using the response chart and received feedback after each presentation. Sixteen impregnated strips, 4 of each taste in 4 different concentrations, and 3 non impregnated blank strips were then presented in a pseudo-randomized order with an inter-trial interval of approximately 25 seconds.
