采用滤纸片法测定了69名健康人舌、软腭的甜、咸、酸、苦四味分布图。用于测试的设备包括直径为8mm的滤纸盘和味道溶液，将其依次稀释（从80%蔗糖分13级，从20%NaCl分12级，从8%酒石酸分12级，从4%盐酸奎宁分14级）。通过测试每种溶液的浓度增加来确定在三个位置（舌尖中心、左侧的叶状乳头和软腭中心）识别每种味道的阈值。我们发现甜味在性别上没有差异，但女性对舌尖上的酸味和软腭上的咸味和苦味更敏感。在不同的位置，甜，咸或苦的味道的味觉阈值没有差异，但两种性别的软腭比舌尖对酸味的敏感性低，在男性中，软腭甚至比舌根对酸味的敏感性低。对于男性和女性来说，吸烟与所有四种口味的味觉阈值增加（更差）有关。
The filter paper disk method was used to determine the map of the 4 tastes (sweet, salty, sour and bitter) on the tongue and soft palate in 69 healthy individuals. The equipment used for testing included filter paper disks 8 mm in diameter and taste solutions, which were sequentially diluted (in 13 stages from 80% sucrose, 12 stages from 20% NaCl, 12 stages from 8% tartaric acid and 14 stages from 4% quinine hydrochloride). The threshold at which each taste was recognized in three locations (center of the tongue tip, foliate papillae on the left side and center of the soft palate) was determined by testing increasing concentrations of each solution. We found no difference by sex for sweet taste but women were more sensitive to sour taste on the tongue tip and to salty and bitter tastes on the soft palate. No difference in taste threshold was noted at the different locations for sweet, salty or bitter tastes, but both sexes were less sensitive to sour taste on the soft palate than on the tongue tip, and in men the soft palate was even less sensitive to sour taste than the tongue root. Smoking was associated with increased (worse) taste thresholds for all four tastes, for both men and women.
