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.

產品說明

ODOFIN 味覺試紙是一種經過驗證的檢測方法，用於評估味覺功能。本套裝為完整版本，可用於測試多達 50 名受測者的味覺能力。

在進行整體口腔味覺測試時，將試紙放置於舌頭上並閉上口腔（受測者可自由移動舌頭）。若需測試舌頭特定區域的味覺敏感度（例如側向測試），則保持口腔開啟，讓試紙僅接觸指定區域，直到受測者作出回應。

ODOFIN 味覺試紙測試

完整套裝包含 16 個容器（甜、酸、鹹、苦各 4 種濃度）及 3 個空白試紙容器。總計為 19 個容器，每個容器 50 條試紙，共 950 條試紙。產品附有英文（或德文）說明書，並以盒裝形式提供。本套裝可供約 50 人使用。

保存期限

根據說明書：

盒蓋內側（存放試紙容器的位置）以及每條試紙上均標示最佳使用期限。未開封情況下，試紙自生產日起可保存 5 年；開封後，保存期限為 12 個月。請在盒蓋內標示首次開封日期以便記錄。

關於保存期限，Burghart 亦有相關研究文獻支持。

選購：鮮味（Umami）試紙

鮮味試紙為標準套裝的選配項目，包含 4 種不同濃度，每種濃度提供 50 條，共 200 條試紙。

「Umami」為日文，意指「鮮味」或「旨味」，是五種基本味覺之一，與甜、酸、鹹、苦並列。

背景資訊

味覺試紙為浸有味覺溶液的濾紙條，代表四種基本味覺，每種味覺包含四種濃度：

• 甜：0.4、0.2、0.1、0.05 g/mL（蔗糖）
• 酸：0.3、0.165、0.09、0.05 g/mL（檸檬酸）
• 鹹：0.25、0.1、0.04、0.016 g/mL（氯化鈉）
• 苦：0.006、0.0024、0.0009、0.0004 g/mL（奎寧鹽酸鹽）

此方法已被驗證適用於成人及兒童，並廣泛應用於臨床與研究領域，尤其受到兒童與青少年的良好接受度。

測試方式與評估

測試結果可反映受測者辨識四種基本味覺的能力，其重測信度與其他味覺測試方法相當。

測試時，將試紙放置於舌頭前端中央，受測者需指出所感受到的味道（甜、酸、鹹、苦或無味），並在對應的答案卡上作答。

為使受測者熟悉流程，會先隨機呈現各種味覺的最高濃度試紙（高濃度），並在每次回答後提供回饋。

隨後再以隨機順序呈現 16 條不同濃度的味覺試紙（每種味覺 4 條）及 3 條空白試紙，每次測試間隔約 25 秒。
