Sensory and chemical characterisation of Sauvignon blanc wine: Influence of source of origin
2011
Abstract The main objective of the study was to investigate influence of geographical location on volatile composition and perceived flavour profile of Sauvignon wines of New Zealand (Marlborough), French (Sancerre; Loire; Saint Bris), and Austrian (Styria) origin. Nineteen New Zealand wine professionals evaluated 18 Sauvignon wines, 6 from each source of origin, by sensory methods that included intensity ratings to experimenter-provided descriptors, typicality ratings, and classification tasks (non-directed and directed sorting). Results demonstrated that wines from the three sources of origin were separated by sensory analyses, with New Zealand wines dominated by perceived green character…
Microbiological Characterization of Red and White Wines Originated From Vineyards of Getic Piedmont
2014
Abstract The aim of the present paper is to investigate an objective microbiological analysis of the wine by identification of some parameters such as total amount of germs and yeastswhich are contained in the quality wines from Getic Piedmont namely: Bolovanu, Corcova, Drăgășani, Sâmburești, Segarcea, Ștefănești.The Getic Piedmont is a relict geomorphological relief unit with significant variations from the flat, low lands fragmented by moderately rough with strong fragmentation. We have selected by grouping the wines in grape varieties, white wines (Sauvignon, Chardonnay, Riesling) and red wines (Merlot, Cabernet, Pinot noir) which were tested by microbiological tests. The opinion that th…
Can improving a biscuit's nutritional characteristics be compatible with maintaining it sensory quality?
2013
Poster (1 page) ; http://www.pangborn2013.com/; International audience; Authorities encourage people to reduce fat and sugar consumption in public campaigns such as the National Nutritional Health Program in France. French producers are also encouraged to improve the nutritional composition of well-known commercial products by reducing fat and/or sugar contents. The objective of our study was to determine whether it was possible to do so while maintaining the sensory quality of the reformulated products. The study dealt with the impact of fat and sugar reduction on liking and sensory perception of 6 types of French commercial biscuits and cakes. For each type of product, one example of the …
Sweeteners and sweetness enhancers
2017
indexation en cours; PURPOSE OF REVIEW: The current review summarizes and discusses current knowledge on sweeteners and sweetness enhancers. RECENT FINDINGS: The perception of sweet taste is mediated by the type 1 taste receptor 2 (T1R2)/type 1 taste receptor 3 (T1R3) receptor, which is expressed in the oral cavity, where it provides input on the caloric and macronutrient contents of ingested food. This receptor recognizes all the compounds (natural or artificial) perceived as sweet by people. Sweeteners are highly chemically diverse including natural sugars, sugar alcohols, natural and synthetic sweeteners, and sweet-tasting proteins. This single receptor is also the target for developing …
Instrumental and sensory evaluation of eating quality of peaches and nectarines
2012
The influence of flesh firmness on consumer acceptance and its relationship with total soluble solids (TSS), titratable acidity (TTA) and sensory analysis were studied for fruits of ‘September Sun’ and ‘Sweet September’ (low acid) peach (Prunus persica (L.) Batsch), and ‘Maria Dolce’ (low acid) and ‘Venus’ nectarine (Prunus persica (L.) Batsch, var. nucipersica) cultivars. Sensory descriptors, assessed by a short-trained panel, were firmness, sweetness, sourness, aroma, acceptability. Different stages of fruit firmness did not always result in significant differences of TSS, TTA and their ratio, but the panel was able to discriminate fruit ripening stages, in terms of fruit firmness, aroma …
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…

Is the improvement of the nutritional quality compatible with the maintenance of the sensory quality? : the example of biscuits
2013
French biscuit producers are willing to improve the nutritional composition of their products. The. objective of this work was to determine whether it was possible while maintaining the sensory. quality of the reduced product. The first study dealt with the impact of fat and sugar reduction on liking and sensory perception of. 9 types of biscuits and cakes. Results show that children perceived almost no difference and liked. equally the standard and the fat- and/or sugar-reduced variants for most types of biscuits. For. products reduced without adding polyols, adults less like fat- or sugar-reduced variants than. standard ones mainly when they were perceived as less sweet, and to a lesser e…
