Childhood obesity and undernutrition pose significant global challenges, particularly in Peru, where sweet biscuits are widely consumed but often nutritionally unbalanced. To improve the sensory quality of biscuits for children, we proposed selecting biscuits with better characteristics through evaluation with young adults. This study evaluated the impact of reducing sugar and incorporating quinoa flour on the sensory and hedonic perception of biscuits among young adults and school-aged children. Biscuit formulations were assessed using a 9-point hedonic scale and a Check-All-That-Apply (CATA) questionnaire. Young adults (n = 115, 18–25 years) showed moderate acceptance of all treatments, but the selection of the best treatments was influenced by the attributes “crunchy,” “honey,” and “sweet.” The selection of three treatments containing moderate levels of quinoa flour (15%–30%) and reduced sugar (10%–20%) resulted in higher scores of overall liking in children (n = 113, 6–13 years) compared to the evaluation in young adults, with positive attributes (sweet, crunchy, honey, brittle, and buttery) and absence of negative drivers of liking, which demonstrates the effectiveness of the proposed strategy. This reformulation strategy offers a practical approach to addressing malnutrition without compromising sensory quality, providing valuable insights for food industries and policymakers seeking to promote healthier snacks for children.

This article studies how package shape affects consumers' eye movements and product selection for liquid soap products, using eye-tracking data and a choice experiment. The study involved 54 participants with different backgrounds, who chose their preferred product from pairs of photos of different packages. The results showed that package shape influenced consumer attention and choice, and that gender also had an effect on some of the measures. Packages with higher perimeter, eccentricity, and extent were more attractive and likely to be chosen by consumers, while packages with higher area, convex area, and roundness were less attractive and likely to be chosen. This article provides empirical evidence on the effect of package shape on consumer behavior for liquid soap products.

Interstitial space is an important component of food brand logos and provides a key source of information to attract consumer attention. In this research, two studies were conducted to examine whether the interstitial space (compact vs. spacious) of food brand logos affects consumers' food preferences, taking into account the moderating effect of the food nature (hedonic vs. utilitarian). Study 1, a pilot study based on product gaze times, showed that consumers had longer gaze durations and more choices for hedonic products with spacious logos and utilitarian products with compact logos. Study 2 designed a 2 (food brand logo interstitial space: spacious and compact) × 2 (food nature: hedonic and utilitarian) between-subjects experiment to show that compact (vs. spacious) food brand logos are more conducive to consumers' preferences for utilitarian foods, an effect driven by the psychological mechanism of food safety associations; conversely, spacious (vs. compact) food brand logos are more conducive to consumers' preferences for hedonic foods, an effect driven by the psychological mechanism of food indulgence associations.

This study aims to explore the interaction effect between agricultural product types (GI vs. non-GI) and the types of live content on consumers' purchase behaviors. Study 1 employs a mixed-effects model to analyze the data of the live streaming platforms. In Study 2, the experimental design and survey methods are used to collect data. Study 1 indicates that emotional (vs. informational) live content positively influences consumers' purchase intention for GI (vs. non -GI) agricultural products. In Study 2, the mediating role of brand awareness and product awareness is further investigated, and the results show that when purchasing GI (vs. non-GI) agricultural products, the adoption of emotional (vs. informational) live content is more likely to induce consumers' brand (vs. product) awareness and thus increase purchase behaviors. This research highlights the importance for enterprises to differentiate and effectively utilize different live content under live marketing strategies for GI agricultural products.

In exploring how sensation, perception, and attention are conceptualized and assessed, as well as how their impacts on judgment and behavior have been measured in sensory marketing research, we examine the significance of attention and perception, contrasting them with the traditional approach that focuses solely on activating sensations to influence consumer behavior. This highlights a gap in the existing literature, as most studies overlook the interaction among sensation, perception, and attention and how these factors collaboratively affect consumer behavioral outcomes, particularly in a complex multisensory environment. To address this gap, we investigate the impact of attention on the effectiveness of sensory marketing. We begin by discussing the distinct roles of attention and perception, independent of sensation. In the final sections, we provide conceptual recommendations on how researchers can consider the specificities and impacts of attention, present actionable strategies that enhance sensory marketing research, and suggest pathways for future studies in this field.

Marketing theory and practice are increasingly interested in the role of olfactory sense; however, critical questions remain about its role in influencing purchase preference. This research investigated how and why the order of olfaction sensory sampling of products influenced consumer preference. Specifically, this research explored the moderating role of cognitive cues and familiarity principle on order effect. Through three experimental studies, we found that: (1) When consumers sampled three or up to five scents sequentially, they preferred the first sampled scent. (2) When consumers were informed that a certain scent was the last sample of a sequence of products, consumer preference for the last sampled scent was enhanced. (3) when consumers sampled familiar and unfamiliar scents sequentially, they preferred the familiar scent.

With the demand of dog food production continuously rising, the use of sustainable chicken ingredients must be considered. However, given the current trends, pet owners' preferences for fresh chicken over chicken by-products is putting a strain on the global demand for overall chicken protein sources. The objectives of this study were to develop a sensory profile, assess consumer acceptance, and separate and tentatively identify volatile compounds from five different dry canine foods. Descriptive sensory analysis, consumer acceptance, and qualitative analysis utilizing gas chromatography–mass spectrometry (GC–MS) coupled with the headspace solid-phase microextraction (SPME) method was performed on five dry canine foods containing different chicken protein sources. Five highly trained descriptive panelists identified 12 aroma and six appearance attributes for each canine food. For consumer acceptance testing, dog owners were recruited to evaluate the five canine foods for aroma, appearance, and overall liking. Consumers preferred the chicken by-product meal dry canine food and scored it the highest in overall liking, as well as aroma and appearance. Separation and tentative identification of 13 volatile compounds were determined from the highest probability (≥ 75%) and intensity scoring of each compound found in each sample. The majority of volatile compounds consisted of carboxylic acids and aldehydes. Hexanal, heptanoic acid, 2-heptanone, and octanoic acid seemed to be related to oxidized oil aromatics while acetic acid, propanoic acid, and butanoic acid correlated closest to the liver attribute. This study showed that dry canine foods containing different chicken protein sources had similar aroma, appearance, and volatile profiles.
