Preference and acceptability of partially dealcoholized white and red wines by consumers and professionals

International audience; The influence of partial alcohol reduction in wine on consumer appreciation and acceptability was investigated. Two white wines (Chardonnay and Sauvignon blanc) and two red wines (Merlot and Syrah) were partially dealcoholized using reverse osmosis to span a range of three different alcohol contents (14% to 10%) by grape variety.

A group of 35 French wine professionals also comparatively rated their appreciation of the same wines in blind conditions and described them by rating the intensity of 10 informal descr…

P217: Potentiels evoqués gustatifs chez l’Homme en réponse à une stimulation sucrée

Introduction et but de l’etude Les Potentiels Evoques Gustatifs (PEG) peuvent etre detectes en reponse a une stimulation intermittente des recepteurs gustatifs par une saveur primaire. Ils permettent d’explorer la voie sensorielle gustative depuis les bourgeons du gout jusqu’au cortex gustatif. Notre objectif etait double : (1) etablir un enregistrement fiable des PEG chez l’Homme, et (2) determiner les variations physiologiques de l’activite evoquee electrique cerebrale en regard des aires gustatives en fonction de l’intensite du stimulus puis en fonction de l’etat de jeune ou de satiete. Materiel et methodes Des sujets volontaires sains ont ete inclus. Lors d’une 1 re experience, une solu…

Are gut hormones responsible for the decrease of appetitive behaviour for sweet and fatty foods after gastric bypass surgery?

WOS: 000321389200211; International audience; Introduction: Gastric bypass surgery (RYGB) decreases preference for sweet and fatty foods, but the underlying mechanism is not known. This study aimed to investigate the role of the exaggerated satiety gut hormone release on appetitive reward of sweet and fatty taste after RYGB. Method: 13 patients that have undergone previous RYGB surgery (>6 months) and 13 normal weight controls participated in a double-blind placebo-controlled trial comparing the effect of subcutaneous injections of somatostatin analogue (octreotide) which blocks satiety gut hormone responses, and saline (control) on the appetitive reward value of sweet-fat candies. Appetiti…
