Temporal Rate-All-That-Apply (TRATA): A novel temporal method for sensory evaluation

John Castura/ August 8, 2021/ Poster/ 0 comments

This study introduces temporal rate-all-that-apply (TRATA) as a new temporal sensory method. It was inspired by rate-all-that-apply (RATA) and temporal check-all-that-apply (TCATA), but is most similar to multiple-attribute time intensity (MATI) in that the TRATA method allows for simultaneous rating of attribute intensities over time. Only attributes that are perceived are scaled. In this case study, the TRATA method was

Temporal ranking for the characterization and better discrimination of protein beverages with different sweeteners

John Castura/ December 9, 2020/ Poster/ 0 comments

This study proposes the application of ranking to temporal product evaluation to differentiate attribute dominances over time. The ability of the proposed method to discriminate sensory differences was compared to temporal check-all-that-apply (TCATA), a discriminating temporal method for capturing the temporal profile of food and beverage products.

The analysis of temporal check-all-that-apply (TCATA) data

John Castura/ April 30, 2018/ Peer-reviewed Paper, Type/ 0 comments

Temporal check-all-that-apply (TCATA) extends classical check-all-that-apply (CATA) by adding a temporal dimension to the evaluation. From a data analysis point of view, TCATA data are similar to Temporal Dominance of Sensations (TDS) data but differ in that more than one attribute can be selected at any time point. Procedures for analyzing TCATA data can hence be generalized from methods for

What is dominance? An exploration of the concept in TDS tests with trained assessors and consumers

Sara King/ March 1, 2018/ Peer-reviewed Paper/ 0 comments

TDS describes the evolution of the dominant sensory attributes during consumption. Dominance can be assessed as the sensation that captures the attention, the most striking, or the new sensation that pops up, but not necessarily the most intense. This wide definition implies that individual assessors within a panel might assess dominance differently, and even the same assessor could be using

Temporal methods add to innovation

Sara King/ September 3, 2017/ Oral Presentation/ 0 comments

Conventional sensory methods often characterize products as if they are a static aggregation of attribute intensities. But it has long been recognized that many products have an important temporal component, and examples of this are seemingly limitless; consider that foods are chewed and broken down prior to swallowing with accompanying texture changes and flavour release, that carbonated beverages elicit numbing

Perception dynamics of grain-based ready-to-eat cereal products using TCATA

Mpfindlay_9j5a2s5k/ October 31, 2016/ Oral Presentation/ 0 comments

The breakdown of grain-based ready-to-eat cereals in the mouth occurs relatively quickly, but it is at this stage when the consumer experiences directly the sensory properties of the cereal. The feelings, tastes, flavors, and sounds elicited in mouth are not static. Rather, these sensations are perceived dynamically, and evolve within each bite, and over the multi-bite eating experience. Temporal check-all-that-apply

Evaluation of consumer perception dynamics 2.0

Sara King/ October 28, 2016/ Workshop/ 0 comments

Over the last decade, so-called rapid methods for sensory evaluation have been developed to permit consumers to characterize products. The possibility to analyze both sensory perception data and hedonic and other data arising from the same consumers presents new opportunities, but also new challenges to investigate hedonic drivers and other interesting aspects.
