Characterizing dynamic sensory properties of nonnutritive sweeteners with temporal check-all-that-apply (TCATA)

Sara King/ June 20, 2017/ Peer-reviewed Paper/ 0 comments

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 checked words fully describe the sample in any given moment. Here, we characterize the temporal profiles of sweeteners using TCATA. In two experiments, sweeteners were tested in water at concentrations known to elicit weak to moderate sweetness.

The application of calibrated difference-from-control for sensory quality control of distilled beverages

Sara King/ May 30, 2017/ Oral Presentation, Poster/ 0 comments

Sensory quality control is an essential mechanism for ensuring the sensory integrity of a product is not compromised. By conducting sensory testing throughout the distilling process it becomes possible to detect and reject faulty raw ingredients and intermediate products before these advance to the next stages, resulting in further contamination.

A sensory journey from local roots to global innovation

Sara King/ May 29, 2017/ Oral Presentation/ 0 comments

The history of whisky has played an integral role in its marketing and popularization. Spirits started off reflecting their geographic origins and local materials. The growth of blended products in the nineteenth century addressed variability and seasonality. In the last four decades, the character of the production from individual distilleries has blossomed as a differentiator and presented an opportunity to

Identification of drivers of (dis)liking based on dynamic sensory profiles: Comparison of Temporal Dominance of Sensations and Temporal Check-All-That-Apply

Sara King/ February 1, 2017/ Peer-reviewed Paper/ 0 comments

Temporal Dominance of Sensations (TDS) and Temporal Check-All-That-Apply (TCATA) are two multi-attribute methods for dynamic sensory characterization. Previous research has shown that both methodologies provide complementary information. However, it remains an open question which of the two approaches better explains consumers’ hedonic perception of products. In this context, the aim of the present work was to compare TDS and TCATA

Does a familiarization step influence results from a TCATA task?

Sara King/ January 23, 2017/ Peer-reviewed Paper/ 0 comments

Temporal Check-All-That-Apply (TCATA) is a multi-attribute temporal approach that extends CATA questions. It is based on continuous selection of the sensory attributes that are perceived as applicable for describing a focal sample during consumption. Compared to CATA, TCATA is a relatively intense and demanding task for consumers who have to focus their attention on the evolution of the sensory characteristics

Comparison of two TCATA variants for dynamic sensory characterization of food products

Sara King/ December 23, 2016/ Peer-reviewed Paper/ 0 comments

Temporal Check-All-That-Apply (TCATA) has been recently introduced as a method for temporal sensory product characterization. This method requires assessors to select all the terms they consider applicable at each moment of the evaluation, and to de-select terms when they are no longer applicable. In the present work a variant of TCATA, TCATA Fading, is presented and compared to TCATA.

Handling missing data in consumer hedonic tests arising from direct scaling

Sara King/ November 15, 2016/ Peer-reviewed Paper/ 0 comments

In sensory evaluation, it may be necessary to design experiments that yield incomplete data sets. As such, sensory scientists will need to utilize statistical methods capable of handling data sets with missing values. This article demonstrates the advantages of a model-based imputation procedure that simultaneously accounts for heterogeneity while imputing.

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

Sara King/ 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.

Characterizing dynamic sensory properties of nonnutritive sweeteners with temporal check-all-that-apply (TCATA)

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

Temporal check-all-that-apply (TCATA) is a novel rapid sensory method that involves checking and unchecking words to track changes in the sample over time, such that at any given moment the words that are checked completely describe the sample. The use of multiple attributes in TCATA allows for tracking of side-tastes that are not the most intense/dominant sensation, potentially making it
