There is a general paucity of knowledge of the cognitive and perceptual abilities of children to successfully undertake chemosensory-related tasks. An example is that there are no reports of temporal perception by children in time-intensity tasks, or how their responses in these tasks compare with those of adults. The latter paradigm has the potential to reveal differences that may occur during...

Sweet proteins are a family of proteins with no structure or sequence homology, able to elicit a sweet sensation in humans through their interaction with the dimeric T1R2-T1R3 sweet receptor. In particular, monellin and its single chain derivative (MNEI) are among the sweetest proteins known to men. Starting from a careful analysis of the surface electrostatic potentials, we have designed new m...

In a study of the impact of aspartame, fat, and carbohydrate on appetite, we monitored blood glucose continuously for 431 (SE 16) min. Ten healthy males (19-31 years) participated in three time-blinded visits. As blood glucose was monitored, appetite ratings were scored at randomized times. On the first meal initiation, volunteers consumed one of three isovolumetric drinks (aspartame, 1 MJ simp...

Psychophysical judgments often depend on stimulus context. For example, sugar solutions are judged sweeter when a tasteless fruity aroma has been added. Response context also matters; adding a fruity aroma to sugar increases the rated sweetness when only sweetness is considered but not when fruitiness is judged as well. The interaction between stimulus context and response context has been expl...

The perception of sweetness and flavour were studied in viscous solutions containing 50 g/l sucrose, 100 p.p.m. iso-amyl acetate and varying concentrations of three hydrocolloid thickeners (guar gum, lambda-carrageenan and hydroxypropylmethyl cellulose). Zero-shear viscosity of the samples ranged from 1 to 5000 mPas. Perception of both sweetness and aroma was suppressed at thickener concentrati...

The goal of this study was to test the hypothesis that weight loss induced by Roux-en-Y gastric bypass (RYGB) has greater effects on taste perception and eating behavior than comparable weight loss induced by sleeve gastrectomy (SG). We evaluated the following outcomes in 31 subjects both before and after ~20% weight loss induced by RYGB (n = 23) or SG (n = 8): (1) sweet, savory, and salty tast...

Six commercial varieties of organically grown edamame-type soybeans were compared using consumer testing and descriptive analysis. In the affective tests, 54 panelists rated pods and beans for appearance, and beans for aroma, taste, texture, aftertaste, and overall acceptability on a nine-point hedonic scale and willingness to buy on a nine-point category scale. The taste of Sayamusume was like...

Sugars used for sweetening do contribute calories, which can lead to obesity, a risk factor for some chronic diseases. Hence, the craving for sweetness led to discover several forms of alternative sweeteners, which would offer consumers the sweet taste without calories. Stevia rebaudiana Bertoni is a natural herb with low calorie sweetener. Stevioside is one of the principal diterpene glycoside...
