Little is known about avian taste perception and how taste affects food choice. We designed a study to determine the concentrations of aqueous solutions of common chemical taste stimuli that result in altered consumption patterns. Using two-choice taste-preference tests, we studied the taste thresholds of caged cockatiels (Nymphicus hollandicus) for aqueous solutions of potassium chloride, a ph...

Background: The taste of oral liquid dosage forms is a crucial factor that impacts paediatric patient compliance. The electronic tongue (ET) is an emerging tool that could be useful in taste assessment in order to minimize the involvement of humans in such evaluations. Purpose: The aim of this study is to evaluate the taste of commercially available clarithromycin (CM) oral pharmaceutical suspe...

Animals can discriminate among many different types of foods. This discrimination process involves multiple sensory systems, but the sense of taste is known to play a central role. We asked how the taste system contributes to the discrimination of different "bitter" taste stimuli in Manduca sexta caterpillars. This insect has approximately eight bilateral pairs of taste cells that respond selec...

Gustatory neurons transmit chemical information from taste receptor cells, which reside in taste buds in the oral cavity, to the brain. As adult taste receptor cells are renewed at a constant rate, nerve fibers must reconnect with new taste receptor cells as they arise. Therefore, the maintenance of gustatory innervation to the taste bud is an active process. Understanding how this process is r...

The aim of this study was to prepare, using taste-masked granules, tablets which can rapidly disintegrate in saliva (rapidly disintegrating tablet), of drugs with bitter taste (pirenzepine HCl or oxybutynin HCl). The taste-masked granules were prepared using aminoalkyl methacrylate copolymers (Eudragit E-100) by the extrusion method. None of the drugs dissolved from the granules (% of dissolved...

OBJECTIVE To explore shoppers' responses to the taste of different types of cow's milk in a blind taste test and to examine their willingness to purchase lower-fat milk as part of an in-store marketing intervention. DESIGN Participants were recruited on-site in the supermarket to participate in a blind taste test of three varieties of cow's milk and asked to guess what type they sampled. SE...

We report the case of a 16-year-old female patient with taste impairment of the soft palate. After receiving a skull fracture due to a traffic accident, she experienced the taste of bitter chocolate. CT showed the fracture around the right temporal bone. Electrogustometry showed that the decreased sensation of taste was restricted to the right soft palate. Shirmer test showed that lacrimal secr...

Problems of inadequate nutrition and energy intake are common in the aging population. Smell and taste deficits associated with Late-Onset Alzheimer’s Disease (LOAD) may accentuate the decline in nutritional status of elderly individuals and indirectly enhance progression of cognitive problems in LOAD. The objective of this study was to explore and characterize smell and taste recognition abili...
