The metacognitive cue of fluency on taste perception
… This thesis examined the effect of fluency on taste perception and demonstrated where the fluency created an advantage or disfluency created a disadvantage for taste evaluations. Experiment 1 examined the effect of perceptual fluency on taste perception. It was found that perceptual disfluency …

Taste Perception of Multicomponent Fat-Free Liquid Food Systems
Multidimensional scaling results using KYST-2A showed that subjects used 3 dimensions (represented primarily by thickness/sweetness, saltiness, and bitterness) to differentiate samples. Thickness and sweetness strongly represent the first dimension. Although saltiness and bitterness are important …

The flavor impact of G-Rg1 and G-Rb1 on the taste perception of ginseng
… added to a product before imparting its bitter taste into product formulations. There are two ginsenosides present in ginseng that elicit all benefits expected from an energy drink as well as memory enhancement, ginsenoside Rb1 and Rg1 (G-Rg1 and G-Rb1). The main goal of this study was to …

Evaluation of sweet taste perception in habitual and non-habitual consumers of low-calorie sweeteners
… by LCS-related changes in the signaling of sweet taste receptors (STRs) located in both the oral cavity and throughout the GI tract. The stimulation of these STRs can impact the rate of glucose absorption in the intestine and the release of insulin and GLP-1 to help regulate glucose and satiety. …

MODULATION OF TASTE PERCEPTION AS A POSSIBLE STRATEGY IN OBESITY TREATMENT: NEW PERSPECTIVES FOR PRECISION NUTRITION
Taste and gustatory perception, defined as the ability to perceive and recognize a given taste stimulus, play a guiding role in an individual's food choices and food intake. Physiologically, the ability to taste is linked to the presence of receptors and channels on the tongue, the main organ …

The relationship between sweet taste perception and dietary intake : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Human Nutrition at Massey University, Auckland, New Zealand
… Many studies have suggested that sweet taste perception plays an important role in the dietary intake of sugar. However, limited studies investigate this and conflicting results are found. Aim: To better understand the link between sweet taste perception and dietary intake in healthy …

Elucidation of the epithelial sodium channel as a salt taste receptor candidate and search for novel salt taste receptor candidates
Salty taste has evolved to maintain electrolyte homeostasis, serving as a detector for salt containing food. In rodents, salty taste involves at least two transduction mechanisms. One is sensitive to the drug amiloride and specific for Na+, involving epithelial sodium channel (ENaC). A second …

Neural and Psychological Mechanisms of Oral Sensation
… Oral sensory processing extends beyond taste perception, the nerves that innervate the mouth and carry taste information to the brain also carry chemosensations, thermal sensations and somatosensations. While a great deal is understood about oral chemo and thermal perception, this thesis …

The Influence of Dietary Flavanol Mean Degrees of Polymerization on Sensory Preference Trends and the Metabolic Syndrome
… risk, reduced quality of life, and altered taste perception of foods. With increased occurrence of these metabolic diseases, there is a greater need for research oriented towards using lifestyle modifications to combat illness. A relationship between flavanol consumption, health benefits, …

Taste physiological mechanisms and their health implications, analyzed by genetic, epigenetic, and artificial intelligence analyses
Taste perception is a complex trait influenced by genetic, epigenetic, physiological, and pathological factors, with significant implications for nutrition, health, and disease. Our studies integrated molecular biology, psychophysics, and advanced machine learning methods to explore …

A theory-based exploration of adding sugar to beverages in Lebanese public school children
… feeding practices and parental style, and (5) taste perception. In the quantitative study, a multiple linear regression showed that at time 1, perceived behavioural control predicted behaviour. However, at time 2, none of the TPB variables predicted the behaviour. The systematic review of …

The Interaction of Iron with Proteins and Sugars in Biological Fluids and Beverages
… overall goal of this study is to investigate the taste interaction between iron and sweeteners, and the interaction between iron and proteins in bovine milk and human saliva. Based on pairwise-ranking sensory test, we have found that sweetness of sweeteners was varied with different concentrations …

Sensory Perception of Saltiness and Bitterness in Oil-in-Water Emulsions
… was to evaluate saltiness and bitterness perception in oil-in-water emulsion systems. For that purpose, three experiments were performed: A sensory threshold study, a descriptive sensory and physical property evaluation, and a psychophysical assessment of taste perception in emulsion …

Study on the effects of bitter taste receptor on the rat pulmonary artery
Bitter taste receptors (TAS2Rs) have been implicated in roles other than taste perception. TAS2R agonists exert vasorelaxant effects in vascular smooth muscle from guinea pig, mouse and humans. We hypothesis that bitter taste agonists could modulate the pulmonary artery vascular tone. The …

Understanding the role of human microbiota on sensory perception
… environmental factors, wherein (chemo)sensory perception is reckoned amongst the most influential. Analogously, chemosensation is affected by a myriad of determinants, and this warrants the commonly observed large variation in how tastes and smells are perceived among individuals. Given how …

Molekulare Grundlagen der Bittergeschmackswahrnehmung in der Maus
Der Bittergeschmack dient Säugern vermutlich zur Wahrnehmung und Vermeidung toxischer Substanzen. Bitterstoffe können jedoch auch gesund sein oder werden oft bereitwillig mit der Nahrung aufgenommen. Ob sie geschmacklich unterschieden werden können, ist allerdings umstritten. Detektiert werden …
