Figure 2.

(a) An example of a test sheet (allowing for one sensitivity measurement to a given taste). The color symbolizes the location of the tasty discs and the increasing intensity of the taste intensity. Dimensions of the sheet: 11 × 16 × 0.06 cm. Discs: 18 mm in diameter and 2.54 cm² in area. (b) The procedure for detaching and tasting the discs was as follows: detach the disc from the test sheet by holding it by the gripping tab, put the upper face of the disc (marked with a small cross) in contact with the tip of the tongue (first third) for a maximum of 4–5 s, and then discard the disc. After a short pause (10 s), subjects could evaluate the next triplet of discs.
