Bottled mineral water: classic and temporal descriptive sensory analysis associated with liking

Abstract

Purpose The purpose of this paper is to determine the classic (static) and dynamic sensory profile of different bottled mineral water samples, and to evaluate the consumer’s liking of the products. Design/methodology/approach Classic quantitative descriptive analysis (QDA) and temporal dominance of sensations (TDS) were applied to four brands of bottled mineral water and the liking of the products was evaluated by consumers. Findings The dissolved mineral concentration is highly correlated to the liking and influences the sensory profile of the samples in a substantial way. The higher the mineral content, the lowest is the liking. Refreshing, residual plastic taste, musty, metallic taste, medicine taste and viscosity were relevant attributes to the samples differentiation through the static evaluation, while refreshing and viscosity were dominant in the dynamic monitoring. Some information might have been lost by the nature of the TDS method, based on dominance concept. Sweet taste contributed positively and musty taste negatively to the acceptance. Originality/value This paper demonstrated that TDS can be used as a complementary tool to the QDA, contributing to a deeper comprehension of the differences among samples, even in products with low differences, such as bottled mineral water.

“…In addition, a chi-square test per cell was used to identify the source of global chi-square variation at the contingency table (Danner & Menapace, 2020). Chi-square per cell shows if the observed values of each cell are significantly higher, lower or equal to the theoretical values and allows a deeper interpretation of results (Pacheco et al, 2018;Symoneaux, Galmarini, & Mehinagic, 2012).…”

“…Qualitative methods are efficient in this approach as they offer clairvoyance to consumer motivations and thinking with a greater degree of flexibility that would not be available through strictly quantitative methods (Jervis & Drake, 2014). Individual and group interviewing such as laddering (Polizer Rocha, Lapa‐Guimarães, de Noronha, & Trindade, 2018) and focus groups (Esmerino et al, 2017), respectively, projective techniques (Pacheco et al, 2018) and observational tasks (Scagliusi, Porreca, Ulian, de Morais Sato, & Unsain, 2018) are among the most common methods used to traditionally collect qualitative data on consumers' perception.…”

“…The consumer bases his choice on extrinsic factors, such as brand and personal habits (Pacheco et al, 2018). Mineral waters are products differentiated by intrinsic factors, mainly by their aroma and avor, which are classi ed according to the hydrochemical parameters that, in turn, result from the characteristics of the rocks and the aquifer (depth of the water table, as for circulation, con nement, and porosity) that the water ows until its capture and packaging (Dias and Bernardes, 2016; Guadayol et al, 2016;Pacheco et al, 2018).…”

“…In sensory science, methods of profiling food or beverage products-descriptive sensory analysis ranks among the most extensively used (Varela and Ares, 2012)-these can also be classified as static (Pacheco et al, 2018), dynamic (Schlich, 2017) or rapid methods (Sáenz-Navajas et al, 2016), though rapid ones can be used in static ways. Among static methods, quantitative descriptive analysis (QDA) has emerged as a highly robust means of accurately profiling products and generating information about them (Albert et al, 2011).…”

“…Among static methods, quantitative descriptive analysis (QDA) has emerged as a highly robust means of accurately profiling products and generating information about them (Albert et al, 2011). However, QDA requires members of tasting panels to have received extensive training and have learnt to prioritise attention to predefined product attributes (Moussaoui and Varela, 2010;Pacheco et al, 2018), often determined according to the consensus technique (Albert et al, 2011), selecting those attributes the panel can agree on when making the profiling.…”
