Perception of sparkling wines of varying carbonation levels using quantitative descriptive analysis (QDA) and temporal check-all-that-apply (TCATA)

Sara King/ October 26, 2016/ Poster/ 0 comments

Carbonation is an important temporal sensory property of sparkling wine. In this study, sparkling wines of different carbonation (CO2) levels (n = 11) were prepared through the addition of varying concentrations of dextrose during the winemaking process. Sparkling wines, ranging in CO2 concentration from 0.0 to 7.5 g of CO2/L (P≤ 0.05), were evaluated by a trained panel (n =

Does data capture device affect sensory descriptive analysis results?

Sara King/ October 1, 2016/ Poster/ 0 comments

Research facilities often compare historical to newly obtained data sets. The question arises: can data from recent studies be compared to older studies in which different data collection devices were used? The objective of this study was to determine if data capture device type had a significant influence on sensory descriptive analysis results.

Investigating preference and discrimination via tetradic preference testing: A comparison with placebo preference testing and triadic preference testing

Sara King/ August 26, 2015/ Poster/ 0 comments

The No Preference option is employed increasingly, for example in preference testing related to advertising claims. However, published results indicate that relatively few consumers use No Preference, even for a putatively identical pair. To investigate preference and discrimination, and expressed preference consistency made possible from embedded replication, we evaluate three placebo-related tests:
