Multi-attribute temporal descriptive methods in sensory analysis applied in food science: A systematic scoping review

Among descriptive sensory evaluation methods, temporal methods have a wide audience in food science because they make it possible to follow perception as close as possible to the moment when sensations are perceived. The aim of this work was to describe 30 years of research involving temporal methods by mapping the scientific literature using a systematic scoping review. Thus, 363 research articles found from a search in Scopus and Web of Science from 1991 to 2022 were included. The extracted data included information on the implementation of studies referring to the use of temporal methods (details related to subjects, products, descriptors, research design, data analysis, etc.), reasons why they were used and the conclusions they allowed to be drawn. Metadata analysis and critical appraisal were also carried out. A quantitative and qualitative synthesis of the results allowed the identification of trends in the way in which the methods were developed, refined, and disseminated. Overall, a large heterogeneity was noted in the way in which the temporal measurements were carried out and the results presented. Some critical research gaps in establishing the validity and reliability of temporal methods have also been identified. They were mostly related to the details of implementation of the methods (e.g., almost no justification for the number of consumers included in the studies, absence of report on panel repeatability) and data analysis (e.g., prevalence of use of exploratory data analysis, only 20% of studies using confirmatory analyses considering the dynamic nature of the data). These results suggest the need for general guidelines on how to implement the method, analyze and interpret data, and report the results. Thus, a template and checklist for reporting data and results were proposed to help increase the quality of future research.

Systematic Review of Methods Used for Food Pairing with Coffee, Tea, Wine, and Beer

The current article is aimed at systematically reviewing the research methods used for food pairing with coffee, tea, wine, and beer. The primary aim of this review was to elucidate the state-of-the-art methods used for analysing food and beverage pairings with coffee, tea, wine, and beer; secondarily, to identify the basis of the selection criteria; and lastly, the method used to evaluate those pairings. The search was performed in three databases: Web of Science, ScienceDirect, and Scopus. Criteria for inclusion were studies with an experimental design, a descriptive analysis (DA), and/or hedonic consumer analysis of beverage and food pairing. The outcome had to be measured on a hedonic Likert scale, a line scale, a just about right (JAR), or a modified JAR scale or other relevant scale measurement method for the given attribute. A total of 24 studies were included in this review—the majority aimed at finding good food and beverage pairings. Most pairings were based on suggestions from experts on popular/common, similar origin, or quality of beverages and foods. The outcomes were measured in several different scales, precluding a direct comparison. The 24 articles used in this review did not provide a so-called “golden standard” of the pairing method. Only three articles provided a more scientifically based approach to investigate why a food and beverage pairing is perceived as a good match, using aromatic similarity, the primary taste, and the sensation of koku as their experimental factors.

The influence of companion foods on sensory attribute perception and liking of regular and sodium-reduced foods

Among major contributors of dietary sodium intake, many foods are consumed together with companion foods, specifically condiments and carriers. This study compared sensory profiles and overall liking between commercially available regular and sodium-reduced foods consumed with or without companion foods; and examined changes in sensory profiles and overall liking when foods are consumed in condiment-carrier pairs. Three distinct consumer panels evaluated one of the three condiment-carrier pairs, salsa-corn chips (n = 98, 63% female), ketchup-tater tots (n = 100, 69% female), and soy sauce-cooked rice (n = 98, 70% female). For each panel, consumers evaluated five samples; including the regular and sodium-reduced carriers/condiments alone, the companion food alone, and the regular and sodium-reduced foods each with its companion food. Samples were rated for overall liking (9-point hedonic scale) and the intensity of defining sensory attributes (3-point Rate-All-That-Apply scale). Consumers perceived sensory attribute differences between regular and sodium-reduced corn chips (salty) and soy sauce (salty, sweet), but not ketchup. The presence of the companion food reduced consumer ability to discriminate sensory attributes between regular and sodium-reduced products and changed sensory profiles and liking of the foods. Additionally, consumer heterogeneity in hedonic response identified three consumer segments in each consumer panel. Consumer segments differed in their sensory attribute perception. PRACTICAL APPLICATION: It is possible for the food industry to reduce sodium in a range of companion foods without changing consumer preference. The selection of companion foods is important to consumer evaluation of foods under the context of food pairing; corn chips-salsa and ketchup-tater tots are appropriate food pairs. Future sensory studies on food reformulation toward sodium reduction should target specific consumer segments of product liking and sensory attribute perception, which may in turn be influenced by food consumption frequency.
