Salt and Aroma Compound Distributions Influence Flavour Release and Temporal Perception While Eating Hot-Served Flans.
2021
International audience; To counteract the negative effect of salt overconsumption on health, strategies have been developed to reduce the salt content in food products. Among them, two promising strategies based on odour-induced saltiness enhancement and the heterogeneous distribution of flavour compounds were combined and assessed in four-layer cream-based snacks. To investigate the relationship between saltiness enhancement, temporal release and perception of flavour compounds in hot snacks with heterogeneous distribution of salt and aroma compounds, complementary techniques were used: nose space PTR-Tof-MS (Proton Transfer Reaction-Time of Flight–Mass Spectrometry) to assess the release …
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…
Combined heterogeneous distribution of salt and aroma in food enhances salt perception
2015
Aroma–taste interactions and heterogeneous spatial distribution of tastants were used as strategies for taste enhancement. This study investigated the combination of these two strategies through the effect of heterogeneous salt and aroma distribution on saltiness enhancement and consumer liking for hot snacks. Four-layered cream-based products were designed with the same total amount of sodium and ham aroma but varied in their spatial distribution. Unflavoured products containing the same amount of salt and 35% more salt were used as references. A consumer panel (n = 82) rated the intensity of salty, sweet, sour, bitter and umami tastes as well as ham and cheese aroma intensity for each pro…
Heterogeneous salt distribution in hot snacks enhances saltiness without loss of acceptability
2013
clef UT: 000318667000026; International audience; Abstract Health issues have led worldwide organisations to encourage the food industry to reduce salt in processed foods. Therefore, different strategies for salt reduction have been investigated. Here, the effect of heterogeneous salt distribution on saltiness perception intensity was assessed to compensate for salt reduction in snack foods. Two models of hot-served baked foods were developed. One model is made of two layers that vary in composition (cream-based and cereal-based layers) and salt (NaCl) concentration; the other one is made of four cream-based layers that vary in salt concentrations. Consumer panels rated the saltiness intens…
Heterogeneous distribution of salt and aroma in hot snacks: flavour perception, saltiness enhancement and liking
2012
Due to the negative effect of salt overconsumption on health, worldwide health authorities have requested food companies to reduce the salt content of their products. However, to reduce the salt content is problematic, as it induces many changes such as modification of texture, reduction of shelflife, and the decrease of palatability of food products. The first part of this work was devoted to investigate different strategies of salt reduction in hot served complex food products. Heterogeneity of salt distribution was investigated in savoury pies composed of a pastry and a cream filling layer, and in four-layer cream-based products. Then, the odour-induced saltiness enhancement strategy (OI…
La répartition hétérogène du NaCl influence la perception salée
2010
Le régime alimentaire occidental conduit à une surconsommation de sodium deux fois supérieure au niveau recommandé. Le sodium est majoritairement apporté par le sel (NaCl) et sa consommation en excès est un des facteurs responsable de l’augmentation de l’hypertension artérielle. Ainsi, les pouvoirs publics recommandent-ils une réduction de 20% de la teneur en sel dans les principaux vecteurs alimentaires, tel que les plats préparés et les snacks. Cependant, il est difficile de réduire le taux de sel dans ces aliments tout en maintenant leur qualité gustative. En effet le sel confère aux aliments une saveur salée gage de leur palatabilité. Ce travail s’inscrit dans une recherche globale sur …

Heterogeneous distribution of aroma and salt in food enhances salt perception
2012
In the worldwide context of healthy diet, taste enhancement is essential to maintain low salt food acceptability. Aroma-taste interactions and heterogeneous distribution of tastants were used as strategies for taste enhancement. However, the combination of these two strategies has never been studied. This study investigated the effect of heterogeneous aroma-salt distribution on salty taste enhancement and consumer acceptability of hot snacks. A four-layers cream-based model food was designed with the same total amount of sodium and ham aroma, but their distribution varied in each layer. Low, medium or large contrasts between layers of salt and aroma concentration were used, according to an …
Salt distribution in food influences salt perception
2010
Salt (NaCl) consumption is recognized as an important factor in the rise of hypertension in industrialized countries. Therefore, health authorities recommend a reduction of 20% of salt content (generally salt is present about 0.5 to 2g per 100g of food) in several food products such as ready meals and snacks. However, salt reduction in processed foods induces numerous technical difficulties since salt has a number of functions: preservation, water and fat binding and flavour enhancement. Indeed, salt gives a salty taste that guarantees food palatability. The present study is in line with global research to reduce salt level in foods while maintaining saltiness. The aim is to evaluate the in…
Heterogeneous salt distribution: A way to enhance saltiness without loss of acceptability
2012
Health authorities recommend a drastic reduction of salt content in food products. However, such reduction leads to a decrease in both saltiness and acceptability. In a series of experiments, we investigated a new strategy to compensate for salt reduction in food. We assessed the effect of heterogeneous salt distribution on saltiness enhancement, and food acceptability. First, we examined whether salt distribution could affect sodium perception in a salty baked food. This model food is composed of two layers: a cream-based and a cereal-based layer. Three salt levels were tested within each layer, according to a full factorial design. A panel of consumers (n=87) evaluated saltiness of each f…
Initial dominance of salty taste increases saltiness in heterogeneous food products
2012
In the worldwide context of healthy diet, a reduction of sodium intake is recommended. However, low-salt foods are poorly appreciated by consumers due to flavour drawbacks. Among the various strategies under investigation to compensate for salt reduction at a sensory level, the combination of aroma-taste interactions and tastants heterogeneous distribution is a promising one. This study aimed at examining the effectiveness of such a strategy throughout the full eating experience. To do so, Temporal Dominance of Sensation (TDS) was used to assess the saltiness enhancement in hot model snacks specifically designed to vary in salt and aroma distribution. According to an optimized experimental …
