The addition of maltodextrin DE 10 to red wine (Cabernet Sauvignon) followed by freeze-drying allowed to obtain a free-flowing (dealcoholized) wine powder (WP) having a phenolic concentration about 3.6 times higher than the original liquid red wine. The powder, having a water activity (a _w) of 0.053 and 0.330 was stored at 28 °C and 38 °C and the content of ten different phenolic compounds was determined by HPLC. Caftaric acid, quercetin 3-glucoside, caffeic acid, gallic acid and resveratrol contents in the WP stored at 28 °C and 38 °C, remained almost constant during 70 days of storage, while epicatechin gallate, catechin, malvidin 3-G and epicatechin showed slight losses (about 15–25 %) during storage. On the contrary, epigallocatechin experienced a strong loss of concentration (around 61 % loss) during storage at the same conditions. A moderate decrease of antioxidant activity, determined by free radical scavenging capacity of the 2,2-diphenyl-1-picrylhydrazyl free radical (DPPH*) and ferric reducing antioxidant power (FRAP) was observed along storage. This decrease was more important at higher temperature (38 °C) and higher a _w (0.33). These results would allow the feasibility of using this WP as a healthy ingredient in alcohol-free powder drinks.

Apple consumers' expectations in Argentina and France were studied by comment analysis of open-ended questions. In an on-line survey consumers stated: attributes which defined quality in an apple; visual, flavor and texture characteristics they liked/did not like to find in an apple. Influence of country, consumption frequency and cultivar knowledge were analyzed by contingency tables, Chi-square per cell tests and Multiple Factor Analysis. Consumers' quality expectations were not the same in both countries. Argentineans and French consumers agreed that quality apples should be juicy (most used term in both countries), tasty, firm and fresh. However, for Argentineans quality was more related to visual characteristics, whereas for French it was driven by flavor. Argentineans used more words but French were more specific, particularly for flavour description. Moreover, frequency of consumption, varieties knowledge and the number of terms given were highly related. Frequent consumers knew more varieties and were more prolific in relation to flavour. Less frequent consumers knew fewer apple varieties and gave more words in the visual category. The use of comment analysis allowed identifying the terms that consumers used in their day to day life to describe apples, finding separately likes and dislikes, in spite of the different languages.

Though the gastronomic sector recommends certain wine–cheese associations, there is little sensory evidence on how cheese influences the perception of wine. It was the aim of this study to dynamically characterize 4 wines as they would be perceived when consumed with and without cheese. The tasting protocol was based on multi‐intake temporal dominance of sensations (TDS) coupled with hedonic rating. In the 1st session, 31 French wine and cheese consumers evaluated the wines ( Pacherenc , Sancerre, Bourgogne , and Madiran ) over 3 consecutive sips. In the following sessions, they performed the same task, but eating small portions of cheese ( Epoisses, Comté, Roquefort , Crottin de Chavignol) between sips. All cheeses were tasted with all wines over 4 sessions. TDS data were mainly analyzed in terms of each attribute's duration of dominance by analysis of variance, multivariate analysis of variance, and canonical variate analysis. Results showed that cheese consumption had an impact ( P < 0.1) on dominance duration of attributes and on preference for most wines. For example, in Madiran , all cheeses reduced dominance duration ( P < 0.01) of astringency and sourness and increased duration of red fruit aroma. Although the number of consumers was small to make extended general conclusions on wine's preference, significant changes were observed before and after cheese intake.

The aim of this study was to identify which attributes impacted the dynamic liking of cheese and wine individually, as well as when consumed together. Three wines (one white, Pouilly Loché; and two red, Maranges and Beaujolais) and three cheeses (Comté, Époisses, Chaource) were individually evaluated by a group of 60 consumers using mono-intake Temporal Dominance of Sensations (TDS) with simultaneous hedonic ratings. The same data acquisition screen was used for all products showing a unique list of 14 descriptors (covering cheese and wine perception) and a hedonic scale for dynamical rating of liking. The dynamic hedonic data were associated with the TDS profiles obtaining Temporal Drivers of Liking (TDL). Furthermore, the nine associations that resulted from combining each wine with each cheese were evaluated by multi-bite and multi-sip TDS. Individually, Chaource had practically no TDL; for Comté, mushroom flavor was a positive TDL, and in Époisses, salty was a negative TDL. As for wines, negative TDL were only found in the red wines: bitter, sour and astringent. Positive TDL for wines were: fruity, spicy and woody. Changes in the dynamic perception had a bigger impact on liking of wine compared to cheese. For the associations, the negative TDL were only three and mostly wine related: sour (for seven out of nine combinations), bitter (six out of nine) and astringent (five out of nine). Positive TDL were more varied (a total of 10 descriptors) and were related either to wine or cheese. As opposed to what was found in cheese alone, salty was a positive TDL in two of the combinations. It was observed that the dynamic sensory perception had a more important impact on liking in wine-cheese combinations than when consumed separately. TDS and TDL have a big potential in the study of food pairing, which should be further exploited.
