Variation in taste perception of different chemical substances is a well-known phenomenon in both humans and animals. Recent advances in the understanding of sweet taste signaling have identified a number of proteins involved in this signal transduction. We evaluated the hypothesis that sequence variations occurring in genes encoding taste signaling molecules can influence sweet taste perceptio...

Conventional taste-masking strategies are used to overcome the bitter taste perception of pharmaceuticals by coating the drug particles and/or adding flavoring agents. However, for certain product categories such as rapid dissolve sublingual tablets, taste-masking is challenging. Programs exploring such formulation strategies in the LO-CS phase or post CS phase possess very little toxicological...

During the last few decades a significant literature has evolved, suggesting that sensory dysfunction, particularly smell and taste dysfunction, can be early markers for neurodegenerative diseases such as Parkinson’s and Alzheimer’s and neuropsychiatric diseases including ADHD and Schizophrenia, all diseases that involve dopaminergic pathology. Smell loss and taste dysfunction appear in clinica...

Gonadal hormones (e.g., estradiol) may regulate feeding by producing a shift in the taste or palatability of food items. This study examined the impact of endogenous gonadal hormones on palatability by investigating sex differences in taste responsivity, as well as the effect of the estrous cycle on taste responsivity, in a rodent model. In the taste reactivity test, male and female Long-Evans ...

OBJECTIVES Middle ear surgery can affect gustatory function because of the course of the chorda tympani nerve (CTN) close to the tympanic membrane. The aim of the study was to evaluate the sense of taste before and after middle ear surgery with a test suitable for clinical routine. Moreover, subjective complaints were assessed over a relatively long period of time. METHODS Forty-seven patient...

The objective of this study was to prepare hyoscine butylbromide (a drug with bitter taste) tablets that can rapidly disintegrate in saliva. The granules were prepared by the extrusion method using aminoalkyl methacrylate copolymers (Eudragit E-100). The drugs dissolved rapidly in medium at pH 1.2 in a dissolution test while none of the drugs dissolved from the granules (% of dissolved < 5%) ev...

The recovery period of the taste responses of rat chorda tympani after application of toothpaste was examined. The response observations of four kinds of essential taste stimuli, 0.1 M sodium chloride, 0.005 M quinine hydrochloride, 1.0 M sucrose, and 0.05 M tartaric acid, were repeated every 2 or 5 minutes. After five observations of summated responses of the chorda tympani with each taste sti...

In most insects, the taste of carbohydrates stimulates an immediate appetitive response. The caterpillar of Manduca sexta is an exception to this general pattern. Despite eliciting a strong peripheral gustatory response, high concentrations of carbohydrates (e.g. glucose or inositol) stimulate the same intensity of biting as water during 2-min tests. We suspected that the lack of feeding stimul...

OBJECTIVE To compare flavoring agents added to activated charcoal (AC) to determine which mixture is most palatable to children. DESIGN Healthy volunteers between the ages of 3 and 17 years participated in a prospective masked trial. Five identical pitchers were prepared containing AC alone, AC with chocolate milk, AC with Coca-Cola (Coca-Cola Corp, Atlanta, Ga), AC with cherry-flavored syrup...

Dear Editor, Bariatric surgery results in greater and lasting weight loss as well as reduces the severity of certain comorbidities.1 The limited literature which has studied taste perception following Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG)2 hypothesises that the consequent taste dysfunction influences food preferences, which prevents postoperative overeating o...
