Effects of oenological tannins on aroma release and perception of oxidized and non-oxidized red wine: A dynamic real-time in-vivo study coupling sens…

2022

International audience; Addition of oenological tannins claims to have a positive impact on wine stability, protection from oxidation and likely sensory persistence. However, their role on red wine aroma during oxidation is controversial. The present study aims at investigating the effect of addition of oenological tannins on wine flavour (mainly aroma) before and after air exposure. Temporal Dominance of Sensations, a dynamic sensory evaluation, was coupled with a dynamic chemical measurement (nosespace analysis) using a Proton-Transfer-Reaction Mass-Spectrometer connected to the nasal cavity of 17 assessors. Results showed that the oxidation of a non-oaked Pinot Noir red wine decreases th…

Dal cane-cibo al dog restaurant

2017

Gastronomic discourse often calls into question issues surrounding animality, but it’s not only the imposition of Paleo or vegetarian diets encouraging or banning the consumption of meat which are becoming increasingly popular subjects. New trends in animal foods such as the appearance and growth of dog restaurants or the increase in attention being given to the nutritional quality of dry dog food are becoming important areas of discussion too, and while some traditionalists will always view the dog as a beast, contrasting progressive ideas are now being aired in the media. In this article we will talk about food philosophies and restaurants (both human and animal) to showhowthey communicat…

Children's acceptance of new foods at weaning. Role of practices of weaning and of food sensory properties

2011

International audience; Weaning (i.e. introduction of complementary foods) is a transitional process between the consumption of a unique food, milk, and family foods. This review of existing literature regarding factors favouring the development of food acceptance at the beginning of weaning underlines in particular the roles of repeated exposure, of introduction of a variety of foods, of timing of introduction of weaning foods, and of food sensory properties (texture, taste and flavours). All factors appear to play a role in the acceptance of weaning foods. The efficiency, most favourable windows and long-term impact of each of these factors is not known accurately.

Creation of a food taste database using an in-home "taste" profile method

2014

International audience; The purpose of this study was to create a food 'taste' database using an innovative in-home profile method. The five basic tastes and fat sensation were studied. The proposed method consisted in an intensive training in laboratory (55 h, 5 months) immediately followed by an in-home measurements phase (8 months) during which 12 trained panelists had to evaluate the five tastes and fat sensation of the foods they typically consumed. The rating scales were inspired by scales used in the Spectrum (TM) method. During the in-home measurement phase, ratings were reported thanks to a web-based tool and each month the panelists returned to the laboratory for a 2-h retraining …

How trigeminal, taste and aroma perceptions are affected in mint-flavored carbonated beverages

2010

 ; The integration of olfactory, taste and trigeminal perceptions must be taken into account to better understand the perception of beverages. To do this, seven beverages were formulated to investigate the role of ingredients on trigeminal perception. All mutual interactions between olfactory, gustatory and trigeminal perceptions were studied. Instrumental measurements and sensory evaluation were used to elucidate both physicochemical and sensory interactions. Sensory profiling was conducted according to monadic product presentation, and in vivo aroma release was assessed in the nasal cavities of subjects during beverage consumption. This study further revealed the influence of trigeminal p…

Effect of Opuntia ficus-indica Mucilage Edible Coating in Combination with Ascorbic Acid, on Strawberry Fruit Quality during Cold Storage

2021

Strawberry fruit is a nonclimacteric fruit and is one of the most consumed berries in the world. It is characterized by high levels of vitamin C, folate, vitamin E, β-carotene, and phenolic constituents as well asanthocyanins that are strictly related to health benefits. Strawberries are highly perishable fruit with a very short postharvest life due to their susceptibility to mechanical injury, rapid texture softening, physiological disorders, and infection caused by several pathogens (yeast and mold) that can rapidly reduce fruit quality. The aim of the present study was to evaluate the effect of the application of Opuntia ficus-indica mucilage in combination with ascorbic acid, as edible …

Determination and gustatory properties of taste-active compounds in tomato juice

2003

The water-soluble compounds of a tomato juice selected for its high taste intensity and quality, have been investigated by both physico-chemical and sensory analyses. The physico-chemical assessment of the crude juice led to the construction of a synthetic model juice. Although 97% of the material contained in the crude juice has been identified and quantified, significant sensory differences between the crude and model juice have been found concerning bitterness and sharpness, showing that the components responsible for these gustatory descriptors have not yet been identified in the juice. For the other descriptors: sweetness, saltiness, sourness, umami and astringency, no significant diff…

Evolution of the taste of a bitter camembert cheese during ripening : characterization of a matrix effect

2001

The objective of this study was to characterize the effect of ripening on the taste of a typically bitter Camembert cheese. The first step was to select a typically bitter cheese among several products obtained by different processes supposed to enhance this taste defect. Second, the evolution of cheese taste during ripening was characterized from a sensory point of view. Finally, the relative impact of fat, proteins, and water-soluble molecules on cheese taste was determined by using omission tests performed on a reconstituted cheese. These omission tests showed that cheese taste resulted mainly from the gustatory properties of water-soluble molecules but was modulated by a matrix effect d…

Enhancing salty taste through odour–taste–taste interactions: Influence of odour intensity and salty tastants’ nature

2013

WOS:000315557500017 ; www.elsevier.com/locate/foodqual; International audience; Decreasing the sodium content in food products without changing consumer acceptability has become an important challenge for the food industry, and several strategies are currently under investigation to reach this goal. This study investigated the effectiveness of saltiness enhancement by an odour to maintain the perception of saltiness in reduced salt content solutions. In the first experiment, we tested the hypothesis that odour intensity drives the level of saltiness enhancement. The results showed that odour can increase the salty intensity by 25%, while no clear influence of odour intensity either in taste…
