[Influence of a high-carbohydrate meal on taste perception].

INTRODUCTION

Taste sensitivity varies greatly in individuals and depends on many external and metabolic conditions.

MATERIAL AND METHODS

The studied group consisted of healthy, non-smoking 41 women and 40 men, aged 19-29. The volunteers were examined in fasting state and after a high-carbohydrate meal. Taste sensitivity to sweet, salty and sour as well as hedonic response to taste were examined by means of gustometry examination recommended by Polski Komitet Normalizacyjny (Polish Committee for Standardization).

RESULTS

It has been shown that in women the meal did not influence the intensity of sweet taste perception of saccharose solutions or the hedonic response to taste, whereas in men it caused a statistically significant decrease in the intensity of taste perception and in the hedonic response to the sweet taste of suprathreshold saccharose solutions. The meal did not influence the salty taste perception in a statistically significant way, neither in men nor in women. After the meal, the women perceived the sour taste with more intensity than in fasting state, whereas in men such influence was not observed.

CONCLUSIONS

1. The consumption of a high-carbohydrate meal influences the sweet and sour taste perception and the effect is sex-dependent: - in men, both the taste sensitivity to saccharose and the hedonic response to sweet taste were decreased, whereas in women such influence was not observed; - in women, the taste sensitivity to citric acid increased and the hedonic response to sour taste decreased, whereas in men such influence was not observed. 2. There is negative correlation between the intensity of taste perception and the hedonic response to the sweet taste both in men and in women after a high-carbohydrate meal, whereas in fasting state such correlation was not observed.
