RESUMO

Aquaponics, the combined rearing of fish and hydroponic horticulture, has great potential for sustainable food production. Despite increasing research and investments in commercial scale systems, aquaponics is not yet a successful industry and most businesses report negative returns. Aquaponic produce is thought to contain added value to the consumer, and the environment. As most consumers are unaware of aquaponics and their benefits, little is known of its potential market. The present study addresses this gap by analysing willingness to consume aquaponic produce at different price levels in Israel and Australia. We used econometric tools to study the effects of pricing and other factors on revenues in each country. Cluster analysis was used to define groups of potential consumers. The results indicate that 17-30% of the population in both Israel and Australia would prefer to consume aquaponic produce once informed of their added value. Revenues at a given premium would be higher in Israel than in Australia, and higher for a leafy green, than for fish. Different segments of the population differed in their willingness to consume aquaponic produce, as well as in their stated motivations when purchasing food. Conclusions highlight the importance of case-specific research on consumer preferences and economic considerations preceding commercial investment in aquaponics.

RESUMO

Preparation for reuse (PfR) is a fundamental waste management practice that is second only to prevention in the waste hierarchy. The paper, building on advertising literature, investigates how to leverage the pro-social nature of this option for giving products that have become waste a second life. To examine how advertising strategies based on emotional, functional or combined stimuli can be used to increase intention to buy these items, we carried out an experiment on 507 actual visitors a PfR items shop run by a social cooperative in Northern Italy. We found that, depending on consumers' social involvement, both emotional and functional stimuli based on the social impact of preparation for reuse tend to outperform functional stimuli and have a positive impact on brand attitudes by shaping attitudes to advertisements. Purchasing behaviour has a positive impact on attitudes toward the PfR organization and moderates the effect of emotional and combines stimuli on attitudes toward the advertisement. Since emotional stimuli can be freely used by both legitimated and opportunistic companies, the former should seek to preserve their value proposition by making it easier for consumers to recognise actually trustworthy organizations. This is possible combining the use of advertisements with the development of solid customer relationships. To this end, awareness campaigns, closer relationships with stakeholders and third-party verifiable standards and certifications should be considered to reduce the risk of "social washing" in the current second-hand market context.

RESUMO

Current information on the links between the chemistry and hedonic liking of edible mushrooms is scarce. In this study, 84 consumers evaluated the appearance, odor, taste, texture and overall liking of samples of Nordic edible wild mushroom species. Subsequently, multivariate models on the effects of non-volatile compounds, odor-contributing volatile compounds, sensory attributes and hedonic likings were created. The non-volatile compounds were measured with quantitative NMR. The five studied mushroom species were different in their sugar and acid contents. Three consumer clusters were found with species*cluster interactions. Correlations with sensory attributes and chemical components were found, and the multivariate models indicated predictor attributes for each consumer cluster. The results indicate that the sensory properties could be correlated to both volatile and non-volatile compounds, there are consumer clusters with differing likings as regards mushrooms, and these clusters are heterogenic groups with no simple factors such as age explaining their liking scores.

RESUMO

BACKGROUND: Of the 18 043 bird species, the eggs of only hen and quail are generally available to consumers. Thus people are deprived of the opportunity to benefit from the huge diversity of eggs offered by nature. Poultry eggs can vary in their color of albumen and yolk, smell, taste and texture. In this study, sighted and blind people were employed for sensory evaluation with the aim of determining the preferences of consumers toward hard-boiled and scrambled eggs of different species of birds, and whether the appearance of these eggs has an effect on the perception of other sensory impressions. RESULTS: Sighted people differently evaluated the texture of both boiled and scrambled eggs as compared with blind people. This was mainly because blind people largely used their sense of touch for evaluation. All other attributes of boiled eggs were evaluated similarly by both groups of panelists, whereas those of scrambled eggs were evaluated differently. CONCLUSION: The obtained results unequivocally demonstrated that differences in taste of scrambled eggs when served hot are easier to evaluate than those of boiled eggs. On the basis of ranking by the sensory panel, it was established that eggs of birds belonging to the order Galliformes are more preferred by consumers than those of duck and goose. By contrast, eggs of ostrich and emu are characterized by unfavorable sensory profiles; moreover, the albumen of boiled ostrich eggs has an unsightly appearance. © 2019 Society of Chemical Industry.

RESUMO

BACKGROUND: This study was conducted to assess whether there are differences in consumer liking of beef. Samples were collected from different groups and analyses were conducted, including quantitative descriptive analysis, consumer panels and instrumental analyses. Palatability traits, such as aroma liking, tenderness, juiciness, flavour liking and overall liking (OL), were rated by consumers. RESULTS: Warner-Bratzler shear force was negatively associated with tender mouthfeel and consumer tenderness score. Cluster analysis identified four groups of clusters, which were described as 'easily pleased', 'bull beef liker', 'tender beef liker' and 'fastidious' consumers. Cluster group 2 awarded a higher score for bulls and located in a separate region on the external preference map. CONCLUSION: External preference mapping showed the association between consumer liking of beef and sensory attributes. © 2019 Society of Chemical Industry.

RESUMO

OBJECTIVE: To evaluate whether calorie labeling of menus in large restaurant chains was associated with a change in mean calories purchased per transaction. DESIGN: Quasi-experimental longitudinal study. SETTING: Large franchise of a national fast food company with three different restaurant chains located in the southern United States (Louisiana, Texas, and Mississippi) from April 2015 until April 2018. PARTICIPANTS: 104 restaurants with calorie information added to in-store and drive-thru menus in April 2017 and with weekly aggregated sales data during the pre-labeling (April 2015 to April 2017) and post-labeling (April 2017 to April 2018) implementation period. MAIN OUTCOME MEASURES: Primary outcome was the overall level and trend changes in mean purchased calories per transaction after implementation of calorie labeling compared with the counterfactual (ie, assumption that the pre-intervention trend would have persisted had the intervention not occurred) using interrupted time series analyses with linear mixed models. Secondary outcomes were by item category (entrees, sides, and sugar sweetened beverages). Subgroup analyses estimated the effect of calorie labeling in stratums defined by the sociodemographic characteristics of restaurant census tracts (defined region for taking census). RESULTS: The analytic sample comprised 14 352 restaurant weeks. Over three years and among 104 restaurants, 49 062 440 transactions took place and 242 726 953 items were purchased. After labeling implementation, a level decrease was observed of 60 calories/transaction (95% confidence interval 48 to 72; about 4%), followed by an increasing trend of 0.71 calories/transaction/week (95% confidence interval 0.51 to 0.92) independent of the baseline trend over the year after implementation. These results were generally robust to different analytic assumptions in sensitivity analyses. The level decrease and post-implementation trend change were stronger for sides than for entrees or sugar sweetened beverages. The level decrease was similar between census tracts with higher and lower median income, but the post-implementation trend in calories per transaction was higher in low income (change in calories/transaction/week 0.94, 95% confidence interval 0.67 to 1.21) than in high income census tracts (0.50, 0.19 to 0.81). CONCLUSIONS: A small decrease in mean calories purchased per transaction was observed after implementation of calorie labeling in a large franchise of fast food restaurants. This reduction diminished over one year of follow-up.

RESUMO

The high sodium content of kimchi is a contradicting factor from its fame as a healthy food. With the aim of reducing the sodium content of kimchi, the objective of this study was to understand the effect of providing "sodium-reduced" information on the acceptance of kimchi according to the age of consumption. Six sodium-reduced kimchi samples, prepared with different percentages of sodium reduction (25% and 50%) and potassium chloride concentration (none, 0.47%, and 0.93%), were compared to control kimchi (2.0% w/v NaCl). Sensory characterization of the samples was obtained using descriptive analysis. A total of 167 kimchi consumers with balanced proportion of the young (below 40) and the old (above 40) evaluated seven kimchi samples in either of the two conditions: blind testing condition or informed testing condition where each of the samples was provided with a label that informed about "sodium reduction percentage" and "whether a salt replacer was used or not." The results showed that in terms of healthiness perception, Korean female consumers believed that kimchi with a high sodium reduction rate would contribute to health in general, though an unfavorable notion of using a salt replacer was also observed. Also, the results suggested that promoting information about sodium reduction in kimchi would generally increase consumer acceptance. However, this phenomenon was influenced not only by the sample for which the information was provided, but also by the age of consumers with different health interests and kimchi experience. PRACTICAL APPLICATION: The findings of this study showed simply reducing sodium and promoting it with a health claim showed limitation in achieving a high level of sodium reduction, such as a 50% reduction rate, which implied the importance of using supplementary material such as potassium chloride that can fulfill the missing saltiness and flavors of the original product. Promotion of "sodium-reduced" claims in kimchi generally results in increased consumer acceptance. However, the effectiveness of the information was dependent on which sample was provided and the age of the consumers, among whom health interests and kimchi experience differ.

RESUMO

BACKGROUND: Obesity and chronic diseases could be prevented through improved diet. Most governments require at least one type of food labeling system on packaged foods to communicate nutrition information and promote healthy eating. This study evaluated adult consumer understanding and use of nutrition labeling systems in the US and Mexico, the most obese countries in the world. METHODS: Adults from online consumer panels in the US (Whites n = 2959; Latinos n = 667) and in Mexico (n = 3533) were shown five food labeling systems: 1. Nutrition Facts Table (NFT) that shows nutrients of concern per serving; 2. Guideline Daily Amounts (GDA) that shows levels of nutrients of concern; 3. Multiple Traffic-Light (MTL) that color codes each GDA nutrient (green = healthy; yellow = moderately unhealthy; red = unhealthy); 4. Health Star Rating System (HSR) that rates foods on a single dimension of healthiness; 5. Warning Label (WL) with a stop sign for nutrients present in unhealthy levels. Participants rated each label on understanding ("easy"/"very easy to understand" vs "difficult"/"very difficult to understand"), and, for NFTs and GDAs, frequency of use ("sometimes"/"often" vs "never"). Mixed logistic models regressed understanding and frequency of use on indicators of labeling systems (NFT = ref), testing for interactions by ethnicity (US Latinos, US Whites, Mexicans), while controlling for sociodemographic and obesity-related factors. RESULTS: Compared to the NFT, participants reported greater understanding of the WL (OR = 4.8; 95% CI = 4.4-5.3) and lower understanding of the HSR (OR = 0.34, 95% CI = 0.31-0.37) and the MTL (OR = 0.56, 95% CI = 0.52-0.61), with similar patterns across ethnic subgroups. Participants used GDAs less often than NFTs (OR = 0.48; 95%CI = 0.41-0.55), with the greatest difference among US Whites (OR = 0.10; 95%CI = 0.07-0.14). CONCLUSIONS: Understanding and use of the GDA was similar to that of the NFT. Whites, Latinos, and Mexicans consistently reported the best understanding for WLs, a FOPL that highlights unhealthfulness of a product. Therefore, a FOPL summary indicator, such as WLs, may be more effective in both the US and Mexico for guiding consumers towards informed food choices.

RESUMO

Objective: To quantify differences in patient expectations of healthscape (e.g., interior environment) across Western medicine (WM) and Traditional Chinese Medicine (TCM) paradigms. Data sources/study setting: Primary survey data comprise 469 Taiwanese consumers. National insurance coverage of both TCM and WM is an ideal setting to test for differences in healthscape expectations. Study design: Respondents report their recent experience as either exclusive users of TCM, exclusive WM, neither, or dual usage (both TCM and WM), and are randomly assigned to one of two surveys (identical except one refers to WM contexts, the other TCM) to rate the importance of 28 healthscape factors derived from previous studies. Data collection/extraction methods: Multivariate analysis of variance is used to test the research hypotheses. Principal findings: Dual users accept some differences across paradigms. In contrast, exclusive WM users apply their existing WM expectations to TCM contexts, raising the possibility of dissatisfaction and low adoption. Conclusions: A person's experience with TCM is related to acceptance of healthscape differences. Medical service providers of TCM, and by extension complementary and alternative medicine, should devise strategies to ease initial visitation by exclusive WM users. Healthscape designs need not be modeled closely on a WM standard, as dual users accept differences.

RESUMO

The acceptability of Moro, Tarocco, Cara Cara, Shahani, Bream Tarocco, Boukhobza, and Sanguinelli oranges from both commercial and research orchards was tested with adult (n = 152) and child (n = 72) consumers. Qualitative focus groups were also conducted to understand consumer familiarity and thoughts about the fruit. Sensory descriptive and chemical analyses were carried out to identify drivers of liking. Overall, consumers preferred the lighter colored varieties consisting of Tarocco, Cara Cara, and Boukhobza. One cluster of adults (n = 80) showed preferences towards sweet and fruity flavors and away from sourness and citric acid. The second adult cluster (n = 72) was tolerant of the sour fruit but did not like fruit high in bitterness and flavonoid content. The largest child cluster (n = 42) showed preferences for samples higher in orange and tropical flavors (Cara Cara, Tarocco, and Boukhobza varieties). The appearance of the Cara Cara was strongly liked by the consumer population in both quantitative and qualitative settings. Hunter scale a color values strongly correlated to the higher berry/dried fruit flavors, and concentrations of naringenin. Focus group participants noted that they were relatively unfamiliar with blood oranges. Growers and producers may want to invest in the lighter colored varieties, such as Cara Cara, Tarocco, Boukhobza and Shahani, as these were liked by a majority of consumers and were low in less desirable sensory characteristics, such as bitterness and sourness. PRACTICAL APPLICATION: Through consumer tests, sensory evaluation, and chemical analyses, this research uncovered which sensory properties may drive consumer acceptance of blood and Cara Cara oranges, and informed potential production and marketing strategies for increasing their consumption. This information should benefit the citrus industry as a whole and may enhance the use of specialty oranges by the food, beverage, and food service industries.

RESUMO

The vaquita (Phocoena sinus) is the world's smallest cetacean and most endangered marine mammal. The species is under threat from illegal fishing activities that take place in the upper Gulf of California (UGC). Artisanal use of gillnets to catch shrimp and poach the endangered totoaba are the primary drivers of vaquita population declines due to bycatch. About 80% of shrimp caught in the UGC is sold to the United States, meaning Americans who consume shrimp may have a direct connection to the plight of the critically endangered vaquita. However, this issue as part of the human dimensions of vaquita conservation has been largely unstudied. Additionally, the majority of Americans are unfamiliar with the vaquita which hinders conservation efforts. This article calls for further research into the human dimensions of vaquita conservation, increased collaboration with fishing communities in the UGC, and connecting seafood sellers and consumers with the vaquita crisis.

RESUMO

OBJECTIVE: To assess the immediate impact of the introduction of minimum unit pricing in Scotland on household alcohol purchases. DESIGN: Controlled interrupted time series analysis. SETTING: Purchase data from Kantar Worldpanel's household shopping panel for 2015-18. PARTICIPANTS: 5325 Scottish households, 54 807 English households as controls, and 10 040 households in northern England to control for potential cross border effects. INTERVENTIONS: Introduction of a minimum price of 50p (€0.55; $0.61) per UK unit (6.25p per gram) for the sale of alcohol in Scotland on 1 May 2018. MAIN OUTCOME MEASURES: Price per gram of alcohol, number of grams of alcohol purchased from off-trade by households, and weekly household expenditure on alcohol. RESULTS: The introduction of minimum unit pricing in Scotland was associated with an increase in purchase price of 0.64p per gram of alcohol (95% confidence interval 0.54 to 0.75), a reduction in weekly purchases of 9.5 g of alcohol per adult per household (5.1 to 13.9), and a non-significant increase in weekly expenditure on alcohol per household of 61p (-5 to 127). The increase in purchase price was higher in lower income households and in households that purchased the largest amount of alcohol. The reduction in purchased grams of alcohol was greater in lower income households and only occurred in the top fifth of households by income that purchased the greatest amount of alcohol, where the reduction was 15 g of alcohol per week (6 to 24). Changes in weekly expenditure were not systematically related to household income but increased with increasing household purchases. CONCLUSIONS: In terms of immediate impact, the introduction of minimum unit pricing appears to have been successful in reducing the amount of alcohol purchased by households in Scotland. The action was targeted, in that reductions of purchased alcohol only occurred in the households that bought the most alcohol.

RESUMO

The present study aimed to explore the mediating role of hostile customer relations in the association between emotional dissonance and workers' mental health. Moreover, the moderating role of proactive personality as a buffer against hostile customer relations was assessed. Emotional demands become crucial within professions that involve a direct relationship with clients and, if poorly managed, can negatively affect workers' health and performance. Accordingly, data were collected on a sample of n = 918 mass-retail employees working for one of the leading Italian supermarket companies. Most participants were women (62.7%) with a mean age = 40.38 (SD = 7.68). The results of a moderated mediation analysis revealed that emotional dissonance was related to more hostile customer relations that, in turn, were associated with higher rates of mental health symptoms. Proactive personality emerged as a protecting factor that prevented the onset of conflicts with clients, particularly among workers experiencing high levels of emotional dissonance. The identification of resources enabling management of emotional demands could suggest suitable adaptive strategies for customer-facing roles, thus preventing the occurrence of adverse mental health symptoms.

RESUMO

Across industrialized nations, children and teens are a highly prized target for the advertising industry because young people have a tremendous influence on family purchases; however, media scholars have long suggested that young people are a fundamentally vulnerable audience because they lack the necessary developmental competencies to adequately process and protect themselves from advertising communications. Yet, the precise developmental mechanisms have not been clearly articulated nor is there a clear understanding of how these competencies extend across childhood contexts (e.g., developmental phase, cultures). The current study seeks to lend clarity to this matter by looking at the potential influence that children's executive function and emotion regulation have on the relationship between television exposure (as a proxy of exposure to advertising messages and other consumption-oriented media content) and consumer behavior across a broad range of ages from two wealthy industrialized countries. Mothers of young elementary school children (5-8 years) and early adolescents (9-12 years) in the Netherlands (N = 333, 51.7% female child) and the United States of America (N = 810, 49.6% female child) took part in an online survey to report on their child's cognitive/affective development, media use, and consumer behavior (i.e., purchase requests, purchase related conflict). The results showed that across ages, executive function via attentional shifting moderated the link between purchase requests and purchase conflict, whereas positively valenced emotion regulation moderated the same relationship but only for older children. Lastly, the findings revealed that while there are differences in reported behavior among children in these two countries, the developmental processes tend to work in the same manner. The discussion focuses on what these findings mean for children's consumer development as they approach adolescence and how researchers and child advocates should take these developmental factors into account when considering children's potential vulnerability as consumers.

RESUMO

Despite their nutritional benefits, consumption of red meat from alternative sources such as bison, elk, and horse is low when compared to beef. Sensory attributes and drivers of liking were identified for these meats using the Preferred Attributes Elicitation (PAE) and Check-All-That-Apply (CATA) methods. For the PAE study, 25 panelists evaluated beef, horse, bison, and elk meats in three different group sessions (n = 7, 7, and 11), whereas 63 panelists participated in the CATA study. Consumers in both PAE and CATA studies associated horse meat with dry and fibrous appearance, whereas beef was associated with meaty/beefy flavor and aroma: bison with metallic and livery aroma and intense aftertaste and elk meat with livery, fishy, metallic flavor, musky aroma, and bloody aftertaste. Penalty analysis on the CATA data identified similar drivers of meat liking as the PAE groups. The attributes were juiciness, meaty/beefy aroma, tender texture, meaty/beefy flavor, and mild flavor and aroma. Attributes with significantly negative mean impact on liking were dryness, tough texture, livery flavor, and aftertaste. Association of these attributes with horse and elk meats has implication on drivers of dislike for these meat types. Cluster analysis identified a small group of consumers with preference for horse and elk meats, and this may present niche market opportunities for these meat types. Results showed that the PAE method was comparable to CATA for the evaluation of meat from different species and for identification of drivers of liking and that both methods are effective for meat sensory characterization. PRACTICAL APPLICATION: Lean red meat from unconventional sources such as elk, bison, and horse has unique sensory attributes that may influence acceptance. This study characterized the sensory attributes of these meats and their impact on liking using two rapid consumer descriptive profiling methods-PAE and CATA. Undesirable flavor and aftertaste attributes were identified as the major drivers of disliking for these unconventional meats. Both methods gave similar description of the samples, thus confirming the suitability of PAE for descriptive meat profiling by consumer panels.

RESUMO

This study aimed to identify consumers' preferences and impressions of minimally processed "Gala" cultivar apples, using preference tests and word associations. The study was conducted online via the Google Docs tool and sent out via social networks. The participants were 607 individuals, mostly women, mainly between the ages of 18 and 45, with education up to undergraduate and postgraduate level. As regards the preference for minimally processed apples, the profile of the consumer did not influence the choice. The profiles analyzed were gender and education. For the word association test, 11-word categories were formed, and among these, the most important aspect was appearance, followed by taste and texture, which was confirmed by correspondence analysis. Sample A (0 days-no storage) was the most preferred one, differing significantly from the other samples, whereas sample B (3 days of storage) and sample C (6 days of storage) were associated with characteristics for choice of product. The word association methodology revealed the consumer's impressions of the product, in addition to demonstrating simplicity, low cost, speed, and an exploratory character. PRACTICAL APPLICATION: Gender and level of schooling did not influence the choice of minimally processed apples. Appearance was the most cited word in the word association test. Word association is a simple, fast, inexpensive, and projective technique.

RESUMO

BACKGROUND: In light of recent theories in behavioural economics, an intervention program with monetary incentives could be effective for helping patrons order healthy food, even if the incentive is small and less than one's perceived marginal value. METHODS: In this single-arm cluster crossover trial at 26 local restaurants, a 1-week campaign offered a 50-yen (approximately 0.5 US dollars) cash-back payment to customers ordering vegetable-rich meals, while no pre-order incentives were offered during the control period. RESULTS: In total, 511 respondents out of 7537 customers (6.8%), and 704 respondents out of 7826 customers (9.0%), ordered vegetable-rich meals during the control and intervention periods, respectively. During the intervention period, the covariate-adjusted proportion of vegetable-rich meal orders was 1.50 times higher (95% confidence interval [CI]: 1.29 to 1.75), which increased daily sales by 1.77 times (95% CI: 1.11 to 2.83), even when subtracting the cost of cash-back payments. Respondents who reported spending the least amount of money on eating out (used as a proxy measure for income) were the least likely to order vegetable-rich meals during the control period. However, these individuals increased their proportion of purchasing such meals during the intervention period (a 3.8 percentage point increase (95% CI: 2.82 to 4.76) among those spending the least vs a 2.1 percentage point increase (95% CI: 1.66 to 2.62) among those spending the most; P for interaction = 0.001). Similarly, irregular employees exhibited a larger increase (+ 5.2 percentage points, 95% CI: 4.54 to 5.76) than did regular workers (- 1.4, 95% CI: - 1.66 to - 1.05, P for interaction = 0.001). CONCLUSIONS: A program with an immediate low-value monetary incentive could be a public health measure for reducing inequalities in making healthy food choices.
