Temporal Check-All-That-Apply (TCATA) is introduced as a new dynamic method for describing multidimensional sensory properties of products they evolve over time. TCATA extends the (CATA) method. Selection and deselection attributes are tracked continuously time, permitting assessors to characterize evolution changes in products. presented using results from trained panel evaluations yogurt Data also used illustrate approaches exploratory data analysis. Raw each assessor represented indicator...
Abstract Temporal check‐all‐that‐apply (TCATA) is a rapid method where attributes are actively checked and unchecked to track sensations over time, so that the words fully describe sample in any given moment. Here, we characterize temporal profiles of sweeteners using TCATA. In two experiments, were tested water at concentrations known elicit weak moderate sweetness. Before evaluating sweeteners, participants (n = ∼125 per experiment) familiarized with TCATA guided example imaginary samples...
Temporal Check-All-That-Apply (TCATA) is a new dynamic sensory method for which analysis techniques are still being developed and optimized. In this study, TCATA methodology was applied the evaluation of wine finish by trained panelists (n = 13) on Syrah wines with different ethanol concentrations (10.5% v/v 15.5% v/v). Raw data were time standardized to create percentage duration, subsequently segmented into thirds (beginning, middle, end) capture panel perception. Results indicated high...
ABSTRACT Gin is a distilled spirit characterized by juniper flavor, often accompanied other botanical flavors. The objective of this research was to use gin as case study compare temporal dominance sensations (TDS), check‐all‐that‐apply (TCATA), and ranking (TR). Trained panelists used each these methods evaluate the profile six gins (standardized 30% ABV). Differences in temporality were visualized difference graphs for pairwise comparisons across methods. TDS differentiated based on...
Approaches for analyzing temporal check-all-that-apply (TCATA) data are further developed and illustrated using arising from a Syrah wine finish evaluation. Raw smoothed trajectories obtained principal component analysis. Virtual panels partial bootstrap, the attribute citation proportions then projected into solution space to form contrails. Trajectories overlaid on contrails, allowing smoothing be evaluated. Separation between two contrails provides evidence that differ. At individual time...
