Revisiting the Relationship Between Electrogustometry and Sour Taste Perception
نویسنده
چکیده
In a recent study Ellegård, Goldsmith, Hay, and Morton concluded that electrogustometry is neither mediated by sour taste receptors, nor reflects sour taste quality. While aspects of electric taste await a full explanation, such farreaching claims have significant implications for the future of electrogustometry in clinical practice. The current paper presents a critique of the grounds upon which the arguments were based, and suggests that these conclusions may be pre-

A Hypothesis for the Chemical Basis for Perception of Sour Taste
Sour taste has been considered the simplest of the basic tastes because it is elicited only by hydrogen ions. However, there is not a sufficiently clear understanding of that relationship to allow sour taste intensity to be predicted and rationally modified in foods. On the basis of analysis of sensory data from our laboratory and reanalysis of previously published data, we propose a new hypoth...
متن کاملRelationships between acceptance of sour taste and fruit intakes in 18-month-old infants.
The present study examined whether infants show an acceptance for extreme sour tastes and whether acceptance of sour taste is related to infants' fruit intake. Fruit intake of fifty-three infants at 6, 12 and 18 months was assessed using 3 d food records. Sour acceptance of these infants was studied at 18.1 (SD 1.5) months. Acceptance for four solutions differing in citric acid concentrations (...
متن کاملChanges in taste function related to obesity and chronic otitis media with effusion.
OBJECTIVE To evaluate changes in taste threshold in patients with chronic otitis media with effusion (COME) and their relationship with body mass index. A relationship has been suggested between pediatric obesity and COME, and we hypothesized that changes in taste function may occur in children with COME and that such changes may be associated with changes in body weight. DESIGN A prospective...
متن کاملHeightened sour preferences during childhood.
Basic research has revealed that the chemical sensory world of children is different from that of adults, as evidenced by their heightened preferences for sweet and salty tastes. However, little is known about the ontogeny of sour taste preferences, despite the growing market of extreme sour candies. The present study investigated whether the level of sourness most preferred in a food matrix an...
متن کاملThe chemistry and physiology of sour taste--a review.
Sour taste is the key element in the flavor profile of food acidulants. Understanding the chemistry and physiology of sour taste is critical for efficient control of flavor in the formulation of acid and acidified foods. After a brief introduction to the main applications of food acidulants, several chemical parameters associated with sour taste are discussed. Special emphasis is given to hydro...
