Fat sensitivity in humans: oleic acid detection threshold is linked to saliva composition and oral volume
2013
Fat perception is assumed to result, at least in part, from in-mouth non-esterified fatty acids (NEFAs) detection. The aim of this study was to better understand how human oral physiology may govern the sensory sensitivity to NEFAs. For this purpose, the detection thresholds for oleic acid were determined for 17 human subjects with highly varying salivary and oral characteristics, and the thresholds were related to their oral and salivary characteristics with conventional and multidimensional data analysis. These thresholds were tested on a dairy oil-in-water emulsion that was specifically designed to avoid biases caused by differences in the initial structure of the emulsion as a function …
Fat and salt contents affect the in-mouth temporal sodium release and saltiness perception of chicken sausages
2013
In cooked meats, sodium chloride is involved in taste, texture and flavour release. So a reduction in the salt content may have an impact on overall perception and acceptability. The aim of this study was to evaluate the influence of composition on sodium release and saltiness intensity in chicken sausages. The rheological properties of the sausages differed according to composition. Temporal sodium release and temporal saltiness intensity were evaluated by four selected subjects when eating sausages. At each time point, the effect of the salt level in sausages on sodium release was positive and highly significant. The effect of lipids on sodium release was negative. Concerning perception, …
Preferences for fat and basic tastes and in 3-, 6- and 12-month-old infants
2011
Fat perception received recent interest, but fat preference in human infants is a matter of debate. The objective here was to investigate fat and taste preferences in the same infants (N= 66) at 3, 6 and 12 months. Preference for a fat solution (sunflower and rapeseed oils mixed with soy lecithin) and for taste solutions (sweet, lactose; salty, NaCl; bitter, urea; sour, citric acid; umami, sodium glutamate) was evaluated. The same method was applied at each age. Mothers and their infant participated in 2 videotaped sessions, during which the 5 taste and fat solutions were assessed in a balanced order. For each taste, 4 bottles (water, tastant, tastant and water) were presented by the experi…
Strategies to enhance saltiness in food involving cross modal interactions
2013
A series of results is reported on cross modal odour-taste interactions as a mean to enhance salty taste in food. Salt-related odours can enhance salty taste in water solutions containing a low level of sodium chloride through odour-induced changes in taste perception. Odour-induced saltiness perception enhancement (OISE) depends on salt concentration (intensity). OISE was also found effective in low-salt content solid model cheese, but texture dependant. A significant saltiness perception enhancement induced by Comté cheese and sardine odours was observed for softer textures only. In ternary odour-sour-salty solutions, sourness enhances saltiness perception additively with salt-related odo…
Les perceptions gustatives chez l'enfant
2005
As soon as the end of gestation, the gustatory system is stimulated by the taste-active compounds carried by the amniotic fluid and its maturation continues until mid-childhood. Facial expressions and relative ingestion methods show that the newborn can discriminate the various taste qualities (bitter, salty, sour, sweet and umami). The range of individual responses is wide. Neonatal reactions to sweet and umami are generally considered to express pleasure. The bitter and sour stimulations lead to hedonically negative reactions. The response to salt taste is less characteristic. Overall, the attraction towards sweet and the rejection of bitter and sour tastes become more pronounced during c…

Taste disorders in disease
2016
Among the different sensory systems, gustation is one of the most elaborate. In its sensory task, gustation is helped by interactions with other sensory systems (olfaction, vision, audition, and somatosensory, trigeminal and thermal sensations). It allows the detection and identification of soluble compounds which can be ingested or must be avoided. This function is fundamental to ingestive behavior (energy intake and selection of nutrients) in order to meet physiological needs. Taste is also fundamental to the genesis of hedonic sensations and, therefore, the desire to eat (appetite). The tasting step is also the first stage of the digestion, absorption, and storage of nutrients due to ant…
Relationships between early flavor exposure, and food acceptability and neophobia
2016
Revue; In the first section of this chapter, an overview of what is known about early flavor exposure, distinguishing between taste and flavor (aroma) exposure is provided. In the second section, we will describe what has been researched regarding the influence of early flavor exposure on the development of food preference, looking at prenatal exposure, exposure received in the context of milk feeding and exposure received in the context of complementary feeding. The third section is a description of what has been shown regarding the relationships between early flavor exposure and food neophobia. The chapter ended with a comment on likely future trends, and by a description of sources of fu…
Pectin concentration, Molecular Weight and Degree of Esterification : Influence on Volatile Composition and Sensory Characteristics of Strawberry Jam
1991
Composition of headspace, consistency, taste and flavor characteristics were determined in jams made with different pectins. At usual concentrations, high methoxylated pectin induced an undesirable modification of typical flavor and intensity of flavor and taste, whereas low methoxylated pectin induced few alterations. At fixed concentration and molecular weight, a decrease in degree of esterification produced a significant decrease in consistency and noticeable modifications of the flavor perception and headspace composition, but no taste alteration. Mechanical reduction of pectin molecular weight significantly modified only the consistency.
