Evaluation of consumer perception dynamics

Sara King/ September 11, 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.

Advances in Temporal Check-All-That-Apply (TCATA) Methodology and Analysis

Sara King/ July 16, 2016/ Workshop/ 0 comments

This session is designed to explore topical priorities in sensory science. Every year there are breakthroughs in subject areas in the field that have the potential to be game-changing. The three presentations are united in their novelty and their potential impact upon the way researchers and practitioners think about the interpretation of studies they may conduct.

Sensory booths and colored lights… fact or fiction?

Sara King/ July 16, 2016/ Oral Presentation/ 0 comments

The world of consumer and sensory research and evaluation is full of a lot of significant academic and business centric research.  The goal of this curated symposium is to present IFT members with a dialog between experts on the real truths behind practices that both practitioners and recipients of results might feel are commonly agreed upon approaches.  Sensory booths and

Temporal Check-All-That-Apply characterization of Syrah wine

Sara King/ June 7, 2016/ Peer-reviewed Paper/ 0 comments

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 for the evaluation of wine finish by trained panelists (n = 13) on Syrah wines with different ethanol concentrations (10.5% v/v and 15.5% v/v). Raw data were time standardized to create a percentage of

Temporal check-all-that-apply (TCATA): Overview and recent developments

Sara King/ May 16, 2016/ Workshop/ 0 comments

Temporal Check-All-That-Apply (TCATA) was recently proposed as a temporal sensory method. It extends Check-All-That-Apply (CATA) by permitting assessors to select and continuously update the attributes that characterize products over time. The method has been applied to a wide range of food and beverage products of varying complexity, as well as non-food products, and has permitted characterization of products using sensory

Does data collection device affect sensory descriptive analysis results?

Sara King/ May 16, 2016/ Peer-reviewed Paper/ 0 comments

The objective of this study was to determine if data capture device type had a significant influence on sensory descriptive analysis results. 12 trained assessors evaluated 4 snack bar products in triplicate on each of three devices (iPod, iPad, external monitor). Four-way univariate analysis of variance detected no significant product by device interaction in 19 of 20 attributes. Products were
