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

Abstract

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 different strategies for determining the dominant attribute the same product evaluation. In this context, the aim of the present work was to explore how trained assessors and consumers conceptualize dominance and how the different interpretations and definitions of dominance might influence results of a TDS test. Two studies were performed, one study with a highly trained panel of 10 assessors and another study with 108 consumers. Trained assessors evaluated three bread samples via TDS and their conceptualization of dominance was explored through an immediate retrospective verbalization task. Consumers evaluated the temporal perception of a commercial milk chocolate sample and answered a series of open-ended questions. Results showed that dominance is a complex construct that is not related to a single aspect of sensory perception, and that different conceptualizations of dominance within a panel can hinder an accurate interpretation of results from TDS studies. Various aspects of dominance are highlighted and discussed: how attributes are selected, which are the drivers of transitions between dominant attributes, how the competitive effects of attributes and modalities are manifested, how some phenomena like dumping or dithering could happen at some stages and why. Practitioners are advised to ensure that their interpretation of TDS data is made within the context of the dominance definition they instructed assessors to use. Implications of the results for the application of TDS with trained assessors and consumers are discussed.Dear Sara, Please find attached the third revised version (R3) of the paper entitled "What is dominance? An exploration of the concept in TDS tests with trained assessors and consumers" by Paula Varela, Lucía Antúnez, Mats Carlehög, Florencia Alcaire, John C. Castura, Ingunn Berget, Ana Giménez, Tormod Naes and Gastón Ares.We hope editor and reviewer are now happy with the amendments. (ISO, 2016). Assessors were explained that they had to select the attribute that caught their attention at each moment of the evaluation, which was not necessarily the most intense. In addition, training sessions to familiarize the assessors with the data collection procedure were conducted. Results from the qualitative task showed that intensity was one of the various criteria underlying the selection of the dominant attribute, which confirms that no confusion existed between intensity and dominance. Line 579 : conclusion To be clear, I am not in line your conclusion !! but Ok it's your vision !! Following recent recommendations, training of the panel for TDS was focused on the identification of the attribu...

Temporal profiling of simplified lemonade using temporal dominance of sensations and temporal check‐all‐that‐apply

“…Panelists were familiarized with the TDS (Pineau et al, ) or TCATA (Castura et al ) protocol using the references in Table . Although the debate on how to define “dominant” is still ongoing (Schlich, ; Varela et al, ), in this study, “dominant” was defined as “the attribute that captures your attention, the most striking perception, but not necessarily the most intense sensation” (Pineau et al, ).…”

“…Although the debate on how to define "dominant" is still ongoing (Schlich, 2017;Varela et al, 2018), in this study, "dominant" was defined as "the attribute that captures your attention, the most striking perception, but not necessarily the most intense sensation" .…”

Contribution of temporal dominance of sensations performed by modality (M-TDS) to the sensory perception of texture and flavor in semi-solid products: A case study on fat-free strawberry yogurts

“…The sensory panel consisted of fifteen trained assessors (2 males, 13 females) aged between 20 and 50 years old. Since a confusion between the concepts of intensity and dominance can exist (Varela et al, 2018), this panel was exclusive to TDS and the panelists did not perform QDA.…”

Análise sensorial dinâmica de bacon defumado com madeiras de reflorestamento: um estudo com consumidores

“…Estudos com consumidores têm ganhado espaço entre os métodos de análise sensorial principalmente nos últimos 10 anos, confirmando o que já havia sido descrito por Moskowitz, em 1997, de que os consumidores são capazes de fornecer dados precisos e confiáveis para a caracterização dos produtos VARELA, 2018;. Inúmeras pesquisas têm observado que os resultados da caracterização sensorial realizada por consumidores são semelhantes aos dados fornecidos pela AD (ANTÚNEZ et al 2017a;CHOLLET et al 2011;.…”

“…Palavras com significados semelhantes são agrupadas em categorias, e o número de consumidores que mencionam cada categoria para descrever as amostras é contado e podem ser organizados em forma de tabela. A análise dos dados é realizada utilizando Análise Fatorial múltipla (AFM) ou Análise de procrustes generalizada (GPA), para a obtenção de uma representação consensual e projetiva das amostras(PAGÈS, 2005;VARELA, 2018).Como indicado por, uma das dificuldades do Napping® é restringir os participantes a usar apenas duas dimensões para discriminar diferenças entre os produtos. A análise pode ser realizada tanto com consumidores, quanto com painéis treinados, mas, no caso de muitas amostras, podem ser observadas dificuldades de memorização, fadiga e saturação ao longo das degustações, sendo sugerido cerca de 20 consumidores para resultados estáveis, mesmo que tenham sido relatados estudos com numero maior de participantes (60 a 100)(CHOLLET et al 2011;SIMIQUELI et al 2015).…”
