ABSTRACT
The sense of taste is one of the most important human senses. Alteration in taste perception can greately interfere to our lives, because it influences our dietary habits and consequently general human health. Many physiological and external factors can cause the loss of taste perception. These factors include for example certain diseases, the side effect of the use of certain medicaments, head trauma, gender, dietary habbits, smoking, role of saliva, age, stress and many more. In this paper we are discussing perception of basic tastes and treshold sensitivity during testing of selected groupe of 500 sensory judges. A resolution taste test and sensitivity treshold test were performed using basic tastes (sour, bitter, salty, sweet, umami, astringent, metallic). We have found that the perception of basic tastes decreese with human age. Smoking leads to significant errors in the determination of basic tastes. Different mistakes occures in different age categories. This study suggests further researches, investigating various factors influencing taste perception.  doi:10.5219/259
