RESUMO

The deterioration of the environment, shortage of resources, and frequent occurrence of food safety issues have made people increasingly concerned about themselves while maintaining their health and protecting the environment through food. Organic food, as a healthy and eco-friendly option, is gradually gaining attention. Based on the value-belief-norm theory, this study explores why individuals consume organic food and the range of factors that lead to this consumer behavior. This study adopted a cross-sectional design and collected quantitative data from conveniently selected 300 youth participants in Bangladesh using an online survey. The findings revealed that health values and motivation have a significant positive effect on healthy eating beliefs, which, together with the awareness of the consequences, affect personal norms toward organic food consumption. Personal norms also have a significant positive effect on organic food consumption behavior among Bangladeshi youth. Finally, trust on organic food positively moderates the effect of personal norms on organic food consumption. The findings of this study are expected to foster the development of a comprehensive framework to promote programs and policies focused on organic and healthy food consumption culture among youth in developing nations.

RESUMO

Organic food has gained much importance due to consumers' rising environmental and health concerns. Purchase intention of organic food has been explored widely, but the repurchase intention of organic food has gained little attention among researchers. So, it has become important to explore repurchase intention among generation Z; a generation considered more educated and aware of rising environmental concerns. Generation Z is more tech-savvy and brand conscious, so its impact on repurchase intention through consumer satisfaction has been explored. The data in this paper was collected from 400 respondents through a structured questionnaire in Islamabad, Pakistan. We used the PLS-SEM approach for data analysis and results; we found that social media influence and brand purchase impact brand awareness and positively impact brand awareness on consumer satisfaction. Moreover, it is also found that consumer satisfaction positively impacts the repurchase intention of organic food. Our study found that Generation Z has a strong social media influence, so marketers' managers must consider and address the issues when consumers consider social media for their concerns and suggestion.

RESUMO

BACKGROUND: Little is known about potential health effects of eating organic food in relation to reproduction. OBJECTIVE: We examined associations between organic food consumption and fecundability. METHODS: Data were derived from a preconception cohort study of Danish couples trying to conceive (SnartForaeldre.dk, SF). Participants completed a baseline questionnaire on socio-demographics, anthropometrics and lifestyle and a validated food-frequency questionnaire, which included questions on proportions of organic food consumed within six food groups. Participants were followed up with bimonthly questionnaires for up to 12 months or until pregnancy. Analyses were restricted to 2061 participants attempting pregnancy for ≤6 cycles at enrollment and 1303 with <3 cycles. Fecundability ratios (FRs) and 95% confidence intervals (CI) were estimated by proportional probabilities regression models adjusted for potential confounders including age, lifestyle and socioeconomic factors. Associations were examined for vegetables, fruits, cereals, dairy products, eggs and meat, separately, and for the overall pattern of organic food consumption (organic sum score). RESULTS: The final analytic sample comprised 2069 participants. In the full cohort, organic food consumption was not meaningfully associated with fecundability. Among participants <3 cycles of pregnancy attempt at study entry (n = 1303), the FR was 1.11 (95% CI 0.93, 1.33) for the category 'less than half', for 'more than half' the FR was 1.17 (95% CI 0.99, 1.38) and for 'almost everything' the FR was 1.12 (95% CI 0.97, 1.28). CONCLUSION: Higher consumption of organic foods was not meaningfully associated with fecundability, although slightly greater fecundability was seen among participants with <3 cycles of pregnancy attempt time.

RESUMO

Whether health awareness is self-awareness or conformity awareness is a question worth discussing. Especially under the current trend of organic food consumption, whether it is driven by health consciousness or herd mentality is worth exploring. This is not only about the government's formulation of health policies for the industry (for example, paying more attention to health standards), but also about the sustainable development of organic food consumption (for example, suppliers highlighting their own health advantages). However, there is still little research in this area. Based on data from 1,658 respondents in four first-tier cities in China, this paper explores whether consumers are consuming organic food under health consciousness or herd mentality. This paper uses a logit model to explore the key causes of health consciousness or herd mentality, and uses a propensity score matching (PSM) method to measure the impact of health consciousness and herd mentality on organic food consumption, comparing the effects across age and education groups. The results show that: (1) Individual characteristics, family characteristics, health status, volition, social trust and market education significantly influenced consumers' health consciousness or herd mentality; (2) The main motivation for organic food consumption is health consciousness, but herd mentality plays a role of amplifying this effect.

RESUMO

Improvement in living standards has led to the development and utilization of forest green foods. The study seeks to examine the foundation and potential of forest green food industry in Yunnan Province. By constructing the industrial competitive advantage model, this paper measured and analyzed the competitiveness of forest green food industry in Yunnan Province from 2016 to 2020 by using fuzzy evaluation method and AHP. The conclusions were as follows: (1) The competitiveness of forest green food industry in Yunnan Province was at a medium level with competitiveness index of 83.98. (2) The competitive advantage of forest green food industry in Yunnan Province mainly depended on key factors such as natural endowment and education level. The area is however not having comparative advantage in general factors and important factors. Therefore, there is the need to put in place measures to realise the full potential of forest green food industry in the area by providing players in the sector with requisite skills.

RESUMO

Este estudo comparou a existência de pontos de comercialização de frutas e hortaliças provenientes de sistemas de produção convencional e orgânicos, verificando diferenças nos preços desses alimentos em Curitiba (PR). A coleta de dados aconteceu em 2018, mapeando os pontos de venda cadastrados na Secretaria Municipal de Abastecimento de Curitiba, registrando os alimentos ofertados (convencional e orgânico), e os preços de frutas, legumes e verduras, listados no instrumento de avaliação de estabelecimentos de comercialização dos alimentos para consumo em domicílio (ESAO-s Feiras Livres). Realizou-se o cálculo da razão de preços do dia, registrado conforme os preços praticados na central de abastecimento de Curitiba. Os alimentos convencionais foram encontrados em mais pontos (n =74) em relação aos alimentos orgânicos (n = 15). A oferta dos orgânicos ficou limitada a áreas mais centrais e regiões com maior renda. A maioria dos orgânicos apresentaram preços mais altos que os convencionais. Foi demonstrado que existem desigualdades na distribuição espacial e no preço entre frutas e hortaliças orgânicas e convencionais, indicando que a população do município não tem qualidade no acesso a estes alimentos, dispendendo valores maiores, caso queira optar por escolhas orgânicas.


The study compared the existence of points of commercialization of fruits and vegetables from conventional and organic production systems and verifying differences in the prices of these foods in Curitiba, Paraná. Data collection took place in 2018, mapping the points of sale registered with the Curitiba Municipal Secretariat of Supply, registering the foods offered (conventional / organic), and the prices of fruits and vegetables, listed in the Instrument of Evaluation of establishments in marketing of food for consumption at home (ESAO-s Feiras Livres). The price ratio of the day was calculated, recorded according to the prices practiced at the Central de Abastecimento of Curitiba. Conventional foods were found in more points (n = 74) in relation to organic foods (n = 15). The supply of organics was limited to more central areas, a region with higher income. Most organic products had higher prices than conventional ones. It has been shown that there are inequalities in the spatial distribution and in the price between organic and conventional fruits and vegetables, indicating that the population of the municipality does not have quality access to these foods and may have higher values if they want to choose organic choices.

RESUMO

Consumers perceive organic foods as more nutritious, natural, and environmentally friendly than non-organic or conventional foods. Since organic foods developed, studies on consumer behavior and organic foods have contributed significantly to its development. The presesent study aims to identify the factors affecting consumer buying behaviour toward organic foods in the United States. Survey data are collected from 770 consumers in the Midwest, United States. ANOVA, multiple linear regression, factor analysis, independent t-tests, and hierarchical multiple regression analysis are used to analyze the collected primary data. This research confirms health consciousness, consumer knowledge, perceived or subjective norms, and perception of price influence consumers' attitudes toward buying organic foods. Availability is another factor that affected the purchase intentions of consumers. Age, education, and income are demographic factors that also impact consumers' buying behavior. The findings help marketers of organic foods design strategies to succeed in the US's fast-growing organic foods market.

RESUMO

Organic food consumption and its effects on health remain understudied in adults and in children. The aim of this study was to describe family characteristics associated with feeding infants organic foods during the complementary feeding period. The analysis included 9764 children from the French Étude Longitudinale Française depuis l'Enfance (ELFE) birth cohort. In addition to telephone interviews conducted at 2, 12 and 24 months, a monthly questionnaire about milk feeding and complementary foods (including organic foods) was completed by parents between 3 and 10 months. Associations between family characteristics and feeding with organic foods during complementary feeding were analysed by multivariable multinomial logistic regression. Overall, 51 % of infants never consumed organic food during the complementary feeding period (up to 10 months), 24 % sometimes, 15 % often and 9 % always or almost always. As compared with infants never fed organic foods, those 'often' or 'always' fed organic foods were born to older mothers, with higher education level or family income, and lower pre-pregnancy BMI. As compared with never-smoking women, women who had stopped smoking before pregnancy were more likely to feed their infant organic foods. Feeding with organic foods was also related to long breast-feeding duration and later introduction to complementary foods. To conclude, associations between feeding with organic foods and family socio-economic position as well as infant feeding practices need to be considered when studying the impact of organic foods on children's health and development.

RESUMO

Developing a conceptual model is vital for small-scale organic farmer's credit access to sustain the livelihoods. However, smallholders continually face severe problems in getting finance that lead to reduce investment and in turn, challenges the livelihoods. Therefore, the aim of the present study was to establish and empirically test a theoretical model to explore how agility and innovativeness in organic food value chain finance are achieved through ITI, TRST, CG, ICT, and IS, and how these, in turn, can accelerate financial flow in the value chain and enhance competitiveness. The present study used a survey method and collected data from small-scale farmers, traders, and financial institutions. The model and hypothesis are tested using data obtained from 331 respondents through partial least square structure equation modeling techniques. We argue that development of theoretical model show potential to increase creditworthiness of smallholders and overcome uncertainties that impede traditional value chain credit arrangement. Thus, the present study could provide new ways to integrate the value chain partners, through information and communication technology and governance arrangements in the organic food value chain financing. This study demonstrates that the mediations of innovativeness and agility significantly affect the development of new financial products to make agile the financial flow, which in turn positively influences value chain competitiveness. Significant judgments are required for trustworthy relations among the value chain partners to positively harness innovative product development for swifter value chain finance. Therefore, this theoretical model should not be regarded as a quick solution, but a process of testing, error, and learning by doing so.

RESUMO

As purchase power and consumption knowledge increase, consumers gradually demand safer and healthier products. In addition, consumers focus greater attention on organic food. This study investigates the relationship between environmental consciousness and organic food purchase intention with the mediating roles of perceived food quality and price sensitivity. The objective is to shed new light on our understanding of consumers' perceptions and behavioral intentions toward organic food. Using sample data of 518 consumers in different food retailers in China, empirical results show that environmental consciousness has a positive impact on organic food purchase intention. Perceived food quality has a mediating effect on the link between environmental consciousness and organic food purchase intention. Price sensitivity moderates the relationship between perceived food quality and organic food purchase intention. Furthermore, price sensitivity moderates the indirect effect of environmental consciousness on organic food purchase intention through perceived food quality.

RESUMO

This study investigates the substitution and complementary effects for beef mince attributes drawing on data from large choice experiments conducted in the UK and Spain. In both countries, consumers were found to be willing to pay a price premium for the individual use of the labels "Low Fat" (UK: €3.41, Spain: €1.94), "Moderate Fat" (UK: €2.23, Spain: €1.57), "Local" (UK: €1.54, Spain: €1.61), "National" (UK: €1.33, Spain: €1.37), "Organic" (UK: €1.02, Spain: €1.09) and "Low Greenhouse Gas Emissions (GHG)" (UK: €2.05, Spain: €0.96). The results showed that consumers in both countries do not treat desirable food attributes as unrelated. In particular, consumers in Spain are willing to pay a price premium for the use of the labels "Local", "Organic" and "Low GHG" on beef mince that is also labelled as having low or moderate fat content. By contrast, consumers in the UK were found to discount the coexistence of the labels "Low Fat" and "Organic", "Low Fat" and "Low GHG" and "Moderate Fat" and "Low GHG". The results, however, suggest that in the UK the demand for beef mince with moderate (low) fat content can be increased if it is also labelled as "Organic" or "Low GHG" ("Local").

RESUMO

This paper explores the role of cheap excuses in product choice. If agents feel that they fulfill one ethical aspect, they may care less about other independent ethical facets within product choice. Choosing a product that fulfills one ethical aspect may then suffice for maintaining a high moral self-image in agents and render it easier to ignore other ethically relevant aspects they would otherwise care about more. The use of such cheap excuses could thus lead to a "static moral self-licensing" effect, and this would extend the logic of the well-known dynamic moral self-licensing. Our experimental study provides empirical evidence that the static counterpart of moral self-licensing exists. Furthermore, effects spill over to unrelated, ethically relevant contexts later in time. Thus, static moral self-licensing and dynamic moral self-licensing can exist next to each other. However, it is critical that agents do not feel that they fulfilled an ethical criterion out of sheer luck, that is, agents need some room so that they can attribute the ethical improvement at least partly to themselves. Outsiders, although monetarily incentivized for correct estimates, are completely oblivious to the effects of moral self-licensing, both static and dynamic.

RESUMO

The fall in lamb meat consumption makes it necessary to determine strategies to increase its consumption and the viability of livestock farms. Given this scenario, organic lamb meat emerges as a product with major growth potential. Using crisp-set qualitative comparative analysis (csQCA), this study analyses the profile of lamb meat consumers who decide against consuming organic lamb meat, identifying the main reasons they give for this decision. The findings reveal two majority segments of non-consumers of organic lamb meat, corresponding to 44.2% and 32.8% of conventional lamb meat consumers. In these segments, the main reasons given for non-consumption of lamb meat are, in the following order, supply, higher price and the lack of guarantees that the meat is actually organic. Thus, increasing organic lamb meat consumption necessarily involves greater efforts in the supply chain and greater promotion of information about the controls that guarantee the quality of certified organic lamb.

RESUMO

We assessed the prevalence of front-of-package (FoP) claims in the Brazilian packaged food supply and examined whether foods with claims were more likely to be high in critical nutrients. Using data from a random 30% subsample of 11,434 foods and beverages collected in the five largest food retailers in Brazil in 2017 (n = 3491), we classified claims into nutrition, health, and environment. We examined whether foods with claims were more likely to be high in critical nutrients using 95% confidence intervals. Claims were found in 41.2% of the products. Nutrition claims were the most prevalent (28.5%), followed by health (22.1%), and environment-related claims (5.2%). More than 85% of the breakfast cereals, granola bars, and nectars contained claims, which were found in 51% of the dairy beverages. Foods with nutrition claims were more likely to be high in critical nutrients (65.3%; 95% CI 62.3, 68.2% vs. 54.1% 95% CI 52.1, 56.0). Products with health (52.9%; 95% CI 49.3, 56.4% vs. 58.5%; 95% CI 56.6, 60.3) and environment-related claims (33.5%; 95% CI 27.0, 40.8% vs. 58.6%; 95% CI 56.9, 60.2%) were less likely to be high in critical nutrients. FoP claims are prevalent in Brazil, and nutrition claims are more likely to have a poorer nutritional profile. Policymakers should consider restricting the presence of claims on unhealthy products.

RESUMO

This study aimed to investigate the relationship between sustainability and food, and other possible associations with the socio-demographic characteristics and consumer segmentation, as well as to identify the characteristics of sustainable and unsustainable foods and the sustainable diet concept from a consumer perspective. One hundred and fifty consumers responded a questionnaire with word association, free listing, and sentence completion tasks. A thematic analysis was used to analyze the terms. Sustainability and food were associated with the categories health, food of plant origin, and organic food. Healthy was considered the main characteristic of a sustainable food and degradation to the environment was the characteristic of unsustainable food. Regarding the sustainable diet concept, the terms healthy diet and sustainable production stood out. Individuals of higher educational level associated food and sustainability with natural resource preservation and reuse, while individuals with lower educational levels reported the association with healthy food, nutrition, and food of plant origin. The present findings can help designing strategies to integrate food and nutrition education and formulation of public policies, as well as identifying the target market and understanding how the product or service can meet the consumer's needs.

RESUMO

BACKGROUND: The tendency of some sectors of the population to consume organic food has also come to include baby food. Nevertheless, it is necessary to develop studies to support the true nutritional and toxicological value of these products, making special emphasis in several trace elements. To our knowledge, no studies have been conducted on this type of organic food. METHODS: Weaning foods with different formulations categorized as organic were analyzed to determine Se and Cd contents as well as its bioaccesibility. The analyses were conducted by electro thermal atomic absorption spectroscopy (ET - AAS) after the treatment of the samples with acid mineralization. Besides, macronutrient analyses (protein, fat and dietary fiber) were also developed. Finally, a novelty statistic approach such as @Risk was used to evaluate contributions to DRI or PTWI of Se and Cd derived for consumption of these weaning foods. RESULTS: Se content ranged between 2.44-15.4 µg Kg 1. Samples with meat ingredients showed the highest Se contents, while weaning foods consisting of fruits or vegetables presented the lowest concentrations. Se bioccessible concentration ranged between 1.90-4.35 µg Kg-1 with a greater uniformity amongst analyzed samples. Regarding Cd, concentrations of this heavy metal ranged between 1.23 and 3.64 µg Kg-1. Furthermore, Cd bioaccessibility of organic weaning foods ranged between 0.17 and 1.38 µg Kg-1. The solubility of all samples studied was around 20% from the initial Cd concentration. A negative statistical correlation between fat content - Cd bioaccesible (p < 0.05; r = - 0.756) and Cd content - Se bioaccesible (p < 0.05; r = - 0.777) were also found. CONCLUSIONS: Cd concentrations are considerably lower than those reported in weaning formulas which were not categorized as organic. On the other hand, the analysed organic jars did not represent a significant source of Se. The probabilistic assessment developed, showed that contributions to DRI of Se for infants 1-3 years old by consumption of these weaning foods, are excessively low (15% at best).

RESUMO

Concerns about food safety together with rising disposable income means consumers in developing countries are willing to pay more for safe and high-quality food such as organic vegetables. At the same time, socioeconomic profiles differ in rural versus urban areas leading to differing intakes. This paper investigates regional differences in the determinants of willingness to pay (WTP) for organic vegetables in Vietnam. A contingent valuation survey was used to collect information on consumer preferences of organic vegetables in two regions of Hanoi. Using interval regression model, we found that consumer perception about organic vegetables, trust in labels, and disposable family income increased WTP for organic vegetables in both urban and rural regions. Risk perception of conventional vegetables was high in both regions. However, higher WTP prevailed only in the rural region. Besides, growing vegetables at home affected the WTP only in the rural region while education played a role in the WTP in the urban region. Since rural and urban consumers have different preferences toward organic food, they should not be treated as a homogenous group in formulating organic food policy. This paper also shows that very high price of organic vegetables and lack of trust in organic labels are key barriers to organic purchase. Thus, creating more trust and reducing the price of organic vegetables through lowering certification cost might be a good strategy to expand the organic vegetable market in Vietnam.

RESUMO

The role of consumers' culinary skills on purchasing cues of pork, with emphasis on niche demands (outdoor husbandry and/or certified organic), was assessed in cross-country regions of Spain (Catalonia and Aragon) and Portugal (North). A sample of 974 respondents answered an on-line survey with questions regarding consumer purchasing habits, product involvement and intrinsic and credence attributes. They also chose between two contrasting boneless pork loins and express willingness to pay (WTP) for different product scenarios with different pig farm facilities and for organic pork standards. Two optimal segments were identified based on food-related habits: 'uninvolved' and 'innovative cook lovers', both similarly balanced across socio-demographics, score for credence attributes or consumer involvement dimensions. Overall mean WTP premium across countries was 11.8% for marbled pork, 20.0% for outdoor pork and 24.3% for organic logo stamp. Credence cues of pork claiming health issues (absence of antibiotics and hormone residues) rather than consumers' culinary skills defined the WTP for niche pork in these regions.

RESUMO

OBJECTIVE: Identify the perception operating agents have on the Brazilian National School Feeding Program. METHODS: This is an observational, cross-sectional and quali-quantitative study developed in non-probability and convenience sampling selected in an event promoted by the National Fund for Educational Development in 2015 in Rio de Janeiro. Data were collected through questions related to pre-defined categories concerning the National School Feeding Program. The questionnaire was answered by 43 nutritionists, 41 members of the School Feeding Board, and 16 school feeding administrators from 38 cities of Rio de Janeiro. The narrative analysis was based on benchmarks of cognitive analysis of public policies. The association among variables was investigated with chi-square test, being calculated the power for association testing. RESULTS: The perception of the implementation of the National School Feeding Program has been characterized by some challenges: 1) low number of nutritionists to meet the demand from schools; 2) low adhesion to the public call for the purchase of family farming products due to bureaucratic difficulties and insufficient local food production; 3) reduced coverage of food and nutritional measures due to the restriction of human, material and financial resources; and 4) limitation of the participation of the School Feeding Board due to insufficient training and transport for regular visits. The adequacy of the number of nutritionists showed statistically significant association with the purchase of family farming products (p = 0.002; power = 99%) and with the food and nutritional education activities (p = 0.021; power = 79%). CONCLUSIONS: The results indicate the need for employment of nutritionist in sufficient numbers to meet the demands of the National School Feeding Program, investment in educational activities of healthy eating in schools, training of the School Feeding Board, greater availability of vehicles for school visits and assistance to family farmers in order to facilitate their participation in programs of institutional purchases and encourage the diversification of production.

RESUMO

Conventional agriculture has been widely used to overcome food scarcity in Egypt, but in turn created new environmental, social, and economic problems. Aquaponics has a huge potential as a sustainable solution since it demonstrates promising results for urban food development while providing new entrepreneurship and start-up opportunities. Although it presents a big opportunity especially for developing countries like Egypt, it still requires further studies and researches to fully overcome foreseen challenges. This study discusses the possibility of implementing aquaponics as an alternative to conventional agriculture in Egypt through a comparison between aquaponics and conventional agriculture. The first section of this investigation analyzes the economic feasibility of aquaponics in terms of capital and operational expenditure costs. Then, an experimental comparative study is carried out examining two pilot-scale aquaponics systems (Deep water Culture system and Integrated Aqua-Vegaculture system), where crop quality (vitamins, heavy metals, and pesticides residues) of the two systems has been compared among each other, as well as to that of the commercially available organic food available in supermarkets. Results indicated that both systems produce high-quality safe organic food. The economic feasibility analysis indicated that Integrated Aqua-Vegaculture System is producing more crops with a wider variety of almost 20% less capital expenditure and operational expenditure costs. Fish production for both systems was close, yet slightly higher in Deep Water Culture. Although, on the short term, aquaponics entails relatively high capital and operational expenditure costs compared with conventional agriculture; yet, on the long term, it is more profitable, while saving up to 85% of the water wasted by conventional farming techniques. Finally, the study discusses the main limitations, drawbacks, and future of aquaponics in Egypt where public awareness and a new mindset are needed to highlight the link between agriculture and sustainability.
