The purpose of this paper is to analyse the appropriateness of the analytical hierarchy process (AHP) to measure consumers’ acceptance and preference for eggs enriched with omega-3 (n-3) fatty acids as a health claim and to compare its results with the traditional nine-point hedonic scale.

The AHP was used as a multi-criteria decision analysis. Data were obtained from a face-to-face questionnaire completed by 122 consumers in a controlled environment in Cataluña (Spain).

Results showed the capacity of the AHP to analyse consumers’ acceptance and preferences. An agreement between the AHP and the nine-point scale was found showing that n-3 enriched eggs had lower flavour acceptance, conventional eggs had higher yolk colour acceptance, and conventional and the free-range eggs had similar and higher odour acceptance than the other egg types. The most important attributes that determine preferences for egg purchase were the type and the egg price followed by the origin and the egg size.

The AHP approach seems to be a reliable tool to evaluate consumers’ hedonic preferences. However, further testing on other food products with larger sample size is needed.

The AHP methodology has been widely used in many fields in the last decades, but to the knowledge, not in the sensory field. In the Spanish market, studies that analyse consumers’ preferences and acceptance of eggs are scarce, and new insights are needed particularly regarding n-3 enriched eggs.

The purpose of this paper was to evaluate the differences between common Brazilian beer and pure malt beer in the responses of hedonic scaling, willingness to pay and emotional response.

Two types of beer were selected to be tested – a common beer: Pilsen Skol and pure malt beer: Pilsen Eisenbahn. All the analysis was conducted under three labeling conditions: blind; labeled; inverted label with 70 participants in each test. A nine-point hedonic scale evaluated the acceptance. The consumer was questioned how much he/she would be willing to pay for a bottle of beer that he/she tasted. A questionnaire was elaborated based on the EsSense profile to evaluate emotions; 25 emotions were evaluated using a five-point scale. The socioeconomic status was defined based on consumer's household characteristics.

The acceptance score, positive emotions and willingness to pay were higher for pure malt beer in the labeled test and for common beer (labeled as pure malt) in the inverted test. The findings highlight that information, such as beer type and socioeconomic status, could influence consumer responses by altering hedonic perceptions, emotions and commercial value attributed to different beers. In general, the beer type did not affect the evaluated variables.

Brewing industry should explore in their marketing strategies and state clearly the pure malt label. In restaurants, owners can explore pure malt beers as a strategy for garnering different customer profiles. Technological and production investments should be encouraged to reduce the product price, favoring the final consumer.

This study contributes to understanding the growth in the consumption of pure malt beers in Brazil. Moreover, it brings an overview of the influence of the label/information on regular Brazilian consumers.

The purpose of this paper is to evaluate perceived sensory differences of organic and conventional leafy green vegetables through three sensory tests – blind, informed and inverted and the willingness to buy (WTB) them, and associated factors of organic food consumption by these students.

The research had a cross-sectional design with university students. First, a questionnaire with 16 statements was presented to 233 consumers with a five-point Likert scale response. The assertions were categorized into five domains: trust in organic production; trust in conventional production; positive attitude to organic; affordable price; and perceived quality. Afterwards, a hedonic scaling was conducted with 150 consumers, 50 in each type of test with conventional and organic leafy green vegetables: lettuce (Lactuca sativa L.); kale (Brassica oleracea L.); common chicory (Cichorium intybus); and endive (Cichorium endivia). Visual aspect, taste, texture, bitterness and overall liking for all samples were evaluated on a nine-point hedonic scale.

In general, the participants did not perceive sensory differences during the blind test, but when the information about the vegetables was provided, higher scores were obtained by those products labelled as organic in the informed test and in the inverted test (conventional labelled as organic). This effect was higher for students with stronger attitudes towards organic food. These results indicated that the perceived differences between organic and conventional leafy green by university students tended to be attitudinal and, therefore, can be greatly influenced by the information provided with the product.

This research showed that university students were influenced by the organic label, revealing their sensory perception about vegetables. This study had multiple methodological approaches, including hedonic scaling and consumers’ WTB. This combination allowed identifying the students’ attitudinal tendency in relation to their sensory perceptions of organic green leafy green vegetables.

The purpose of this paper is to describe how three traditional cruciferous vegetables: cabbage (Brassica oleracea var. capitata), collard greens (Brassica oleracea var. acephala) and kale (Brassica oleracea var. viridis) were compared to canola greens through sensory analysis to evaluate panelists' acceptance of canola as a potential source of leafy‐green vegetable.

Canola cultivars were grown at Alabama A&M University, Winfred Thomas Agricultural Research Station, Hazel Green, Alabama, and harvested at the rosette stage. Traditional vegetables (cabbage, collard and kale) were obtained from a local food specialty store. All vegetables were washed and refrigerated overnight. On the day of testing, vegetables were chopped uniformly in preparation for cooking. Using a nine‐point hedonic scale, vegetables were rated for color, flavor and texture. Overall preference was rated using most favorite, second favorite and third favorite.

Color of prepared canola was preferred significantly over other vegetables. There was no significant difference in preference based on texture among canola, collard greens and kale, however, cabbage was significantly preferred by panelists for texture and flavor. The rating for color and texture indicated significant difference among age groups. Response for texture and flavor showed a linear relationship (r² of 0.69) for the model: color texture = flavor, while principal component analysis indicated African‐American females, ages 20‐29 as outliers. The results suggest that canola greens have the appeal of being accepted as an additional tasty Brassica vegetable. Originality/value – This research provides new data on canola as a potential new green leafy vegetable, based on consumer preference.

The aim of the present study was to reveal if sensory properties of smoked food could be considered as decisive in the determination of one product’s preference over another. In addition to this, this work tries to clarify whether the flavour obtained in commercial smoked products was noticed and clearly recognized. This study consisted of two parts; first, a preference testing without physical products (recalled preference) presented using a nine‐point hedonic scale, and second, a difference testing with selected products using the triangular test. Consumers showed a preference for non‐smoked products, particularly for cheese, sausages and chips. The first preference dimension of the internal preference mapping (MDPREF) analysis accounted for 74.6 per cent of total variation indicating overall agreement about likings relating these products, with cheese being the most acceptable overall. Analyzing triangular test results it may be concluded that other factors but sensory ones must be defining consumer representations of smoked food, without a correspondence with its real organoleptic properties.

The purpose of this paper is to examine the influence of sensory attributes of milk chocolate on consumers’ emotions and their hedonic ratings using three commercial brands of milk chocolate.

Quantitative descriptive analysis by a trained panel (n=8) was performed to obtain the sensory evaluation of the samples. A group of 127 consumers evaluated the samples to indicate their hedonic ratings (nine-point hedonic scale) and emotions (EsSense Profile®).

The sensory profiles for the three chocolate types showed clear differences. EsSense Profile® methodology revealed that each type of chocolate had a distinct emotional profile. The premium brand was associated with the highest number of positive emotions, whereas the traditional brand was associated with most of the negative emotions (“bored”, “disgusted” and “worried”). The drivers of liking were mainly positive and unclassified emotions. Also, gender differences in emotional profiling were found.

This study illustrates that sensory and emotional measurements can contribute to a better understanding of consumers’ hedonic liking. Moreover, gender differences found in emotional profiling should raise awareness that gender may lead to different emotional profiling. These gender differences are of interest to food companies, for instance, for food product development or marketing purposes.

This study further contributes to the growing literature on emotions. By combining sensory evaluation by a trained panel and emotional profiling by consumers, this paper explores how combining these measurements can contribute to a better understanding of the drivers of liking for milk chocolate.

The purpose of this paper is to evaluate the influence of the front of a package label and the nutritional claims linked to it over consumers’ expectations as to acceptance, purchase attitude and perception of quality characteristics of a new functional beverage made from cashew nut milk and added with mango juice and prebiotic substances.

Three versions of the front label were developed, which differed just by the type of nutritional claim presented (“0 per cent lactose and 0 per cent cholesterol; 0 per cent lactose, 0 per cent cholesterol and source of fibers, 0 per cent lactose, 0 per cent cholesterol and antioxidants”) and were evaluated in two phases, expectation and informed. For the evaluation, consumers used a multi-attribute scale, the nine-point hedonic scale and a nine-point semi-structured buying attitude scale.

The labels created a positive expectation on the consumers regarding the quality attributes, overall impression (mean = 6.0 “Like slightly”) and buying attitude (mean = 6.0 “Would probably buy”). After tasting the beverage associated with labels (informed phase), consumers kept a positive evaluation. The t-test performed between the pair of means of both phases showed that there has not been a significant difference regarding the quality attributes (p > 0.05), special, attractive, nutritive, healthy and buying attitude (Label 1, p = 0.26; Label 2, p = 0.18; Label 3, p = 0.26) in all labels.

The authors evaluated how the influence of label and nutritional claims in regards to a new product, a beverage made from cashew nut, affects its acceptance, buying attitude and characteristics of quality. Until this moment, there are no studies that evaluate how external attributes affect the acceptance of this beverage totally unique in the Brazilian market.

Mango seed, an agricultural food (agri-food) waste obtained during mango processing is generally discarded and causes environmental stress. In the present study, mango kernel was processed into flour and incorporated into macaron formulation. This study aimed to investigate the antioxidant potential, physicochemical properties, and sensory qualities of macaron after substitution of almond flour (AF) with 0% (control, MC-0), 20% (MC-20), 40% (MC-40), 60% (MC-60), 80% (MC-80) and 100% (MC-100) (w/w) of mango kernel flour (MKF).

Sensory evaluation was conducted using a nine-point hedonic scale (n = 90 young adults) to evaluate the acceptance towards MC-0 (control), MC-20, MC-40, MC-60, MC-80 and MC-100 macaron shells (without mango-flavoured ganache). The most preferred formulated and control macarons were subjected to proximate analyses according to the methods of Association of Official Analytical Chemists for moisture, ash, and protein, and American Oil Chemists' Society for fat. Carbohydrate content was estimated by difference. Physical analyses such as colour, pH and water activity (a_w) were performed using various instrumental techniques. Antioxidant activity of all macaron shell formulations was accessed using 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH-RSA). Sensory evaluation was repeated using a five-point hedonic scale to determine the acceptance of the most preferred macaron (with mango-flavoured ganache) among consumer panels of all age groups (n = 80).

The first sensory acceptance test revealed that macaron shell with 40% MKF substitution (MC-40) was the most preferred formulation among young adults aged 18–35 years old. Moisture and ash contents between MC-0 and MC-40 were found to be similar (p > 0.05), while significant differences (p < 0.05) were observed for the fat and protein contents. Antioxidant activity increased proportionally with increasing MKF substitution and exhibited significant improvement (p < 0.05) in MC-40. Approximately 93% of the panellists expressed their liking towards MC-40 in the second sensory acceptance test. Overall, this study demonstrated that 40% MKF substitution in macaron improved its antioxidant performance without compromising consumers' acceptance.

This innovative research features the incorporation of MKF in the development of an economical and healthier macaron. The results constitute industrial relevant findings pertaining to its application feasibility and nutritional properties. This research has contributed knowledge to the existing literature as well as benefitted food manufacturers to develop value-added products that could meet the needs and expectations of interested parties, including consumers, governmental organisations, health-cautious advocates and healthcare providers.

The purpose of this paper is to optimise and characterise the sensory aspects of gelatos flavoured with different types of coffee preparations (brewed, espresso and soluble), to select the most acceptable formulation and investigate the influence of hedonic claims on the consumer acceptance of this product.

First, the optimal concentration of each coffee type (brewed, soluble and espresso) to be added to the gelato was determined using the just-about-right scale. Second, the acceptance and purchase intentions towards gelatos flavoured with different concentrations of each type of coffee were determined. Finally, the most acceptable concentration for each flavour was selected based on purchase intentions and three other hedonic claims (i.e. texture, flavour and overall impression).

The estimated optimal concentrations of coffee (in relation to syrup) were found to be 111.09, 135.31 and 59.38 per cent for brewed, espresso and soluble coffee, respectively. Gelatos flavoured with soluble coffee were accepted more readily and associated with higher purchase intentions based on the evaluated sensory attributes (i.e. colour, taste, texture, softness and overall impression). The sensory perceptions towards these gelatos did not change significantly based on the evaluated hedonic claims (“coffee”, “soluble coffee” and “gourmet coffee”). This reveals that consumers may not be influenced by specific information and/or hedonic claims in the case of coffee gelatos.

Besides encouraging the availability of a variety of coffee products on the market, this work also supports future studies aimed at the optimization of coffee products from a sensory perspective.

The purpose of this study is to determine the viability of Lacticaseibacillus rhamnosus GR-1 (L. rhamnosus GR-1) in five yogurt samples with or without quinoa, chickpea, soybean and rice flour over various fermentation periods and refrigerated storage durations, with a focus on exploring the potential of functional foods, which provide health benefits beyond nutritional value. Additionally, the study aimed to evaluate consumer acceptance of yogurt fortified with functional flour. Using a nine-point hedonic scale, from 1 (dislike extremely) to 9 (like extremely), participants rated appearance, flavour, texture and overall acceptability.

The samples were inoculated with the probiotic strain L. rhamnosus GR-1 and fermented for 0, 2, 4 and 6 h at 38°C, followed by refrigerated storage at 4°C for 1, 15 and 30 days, respectively. Microbial enumeration was performed throughout fermentation and storage to assess the viability of L. rhamnosus GR-1. A sensory evaluation involving 86 participants was conducted to assess the consumer acceptability of the yogurt samples.

Notably, L. rhamnosus GR-1 achieved viable counts of 108 colony-forming units per mL in all treatments at all fermentation time points. Over the 30-day storage period, no statistically significant differences (p < 0.05) in average pH values were observed among the five treatments, and within each treatment, pH levels remained stable, with an overall mean of 4.2 ± 0.64. Treatment 4, which featured rice flour fortification, received higher hedonic scores from sensory panellists in terms of appearance, flavour, texture and overall acceptability. These findings indicate that incorporating functional flours in conjunction with cow’s milk effectively promotes and preserves the viability of L. rhamnosus GR-1 in yogurt.

Exploring the potential of probiotic yogurt enriched with diverse functional flours to enhance nutritional content and health benefits as well as attract new consumers, this study addressed a critical gap in understanding consumer perceptions and generated insights for creating innovative and health-promoting dairy products.
