Abstract
Purpose
The increase in seafood trade in recent years motivates more detailed studies of different species, as well as evaluation of the nutritional quality of their lipid content. Thus, the purpose of this paper is to evaluate the fatty acid composition, especially the concentrations and fractionation of omega‐3 essential fatty acid in classes of mussels (male and female), oysters, squid, and octopus captured on the south coast of Brazil.
Design/methodology/approach
Fatty acid methyl esters were prepared by methylation of total lipids and were separated by gas chromatography. Quantification of LNA, AA, EPA, and DHA was done against tricosanoic acid methyl ester as an internal standard. Total lipids were fractionated into neutral lipids and polar lipids by classical column chromatography.
Findings
The results of this study were as follows: the female mussel had the highest lipid content (3.52 per cent), followed by the male mussel (2.70 per cent), squid (1.05 per cent), octopus (0.79 per cent), and oyster (0.62 per cent). The samples that had the highest percentages of EPA and DHA in their lipid fraction were the female mussel and squid, respectively. The species belonging to the Bivalvia class (mussels and oysters) showed a predominance of PL, while those belonging to the cephalopods class (octopus and squid), showed a predominance of NL. The n‐6/n‐3 and polyunsaturated fatty acid/saturated fatty acids ratios of all samples analyzed were in accordance with the recommendations. The female mussel had the highest concentration of EPA+DHA omega‐3 fatty acids, corresponding to 1,064.63 mg EPA+DHA 100 g−1 of the sample. So, the consumption of mussels caught off the southern coast of Brazil provides the omega‐3 essential fatty acids.
Originality/value
This paper provides important data concerning lipid quality of seafood caught off on the south coast of Brazil.

The purpose of this paper is to determine the effect of the genotype on the mineral composition (Ca, Cu, Fe, Mg, Mn, Se, Zn and K) of peanuts.
Abstract
Purpose
The purpose of this paper is to determine the effect of the genotype on the mineral composition (Ca, Cu, Fe, Mg, Mn, Se, Zn and K) of peanuts.
Design/methodology/approach
Samples of peanut of three genotypes common names cultivar cavalo vermelho (CCV), cultivar cavalo rosa (CCR) and cultivar tatu (CTA) were used. They were grown in the Maringá, Paraná State region in the same period and were purchased directly from the producer. About 500 g of each genotype were purchased and divided into five equal parts. Each part was analyzed separately and in triplicate (n=15). Mineral analysis was performed in an atomic absorption spectrophotometer with flame ionization.
Findings
Among the analyzed minerals, K occurred in the greatest amount (−600 mg · 100 g−1 of sample), followed by Mg (−250 mg · 100 g−1 of sample), and calcium (−65 mg · 100 g−1 of sample). These values were statistically equal for the investigated genotypes. The iron content varied significantly between samples (from 2.7 to 4.6 mg · 100 g−1 of sample). Zinc content ranged between 6 and 10 mg · 100 g−1 of sample. The contents of the other minerals (Cu, Mn, and Se) were lower than 4 mg · 100 g−1 of sample for all genotypes. The quantities of Mn and Se ranged between 1.2 and 2.1 mg · 100 g−1.
Originality/value
Have few studies of comparative variation in minerals contents in different genotypes of peanuts. In relation to the RDI, the paper observed that 100 g of peanuts can provide significant amounts of most minerals or even more than the RDI amounts, all genotypes being very nutritious.

Abstract
We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

This paper aims to measure income differences between the obese and the non-obese for Brazil and understand which components explain these differences.
Abstract
Purpose
This paper aims to measure income differences between the obese and the non-obese for Brazil and understand which components explain these differences.
Design/methodology/approach
A decomposition method based on recentered influence functions, proposed by Firpo et al. (2007) is used, and the procedure is applied to individuals' income distribution quantiles.
Findings
The results confirm the existence of a wage gap between obese and non-obese men and women. In the case of men, the difference was favorable to the obese in all quantiles and in the case of women, favorable to the non-obese. The biggest differences were observed at the top of the distribution. This difference is mostly explained by observable characteristics that cause the wage gap between groups. The wage structure effect, which may have elements associated with discrimination in its composition, was not relevant in most quantiles.
Research limitations/implications
Unobserved factors can impact the results, but our methodology tries to minimize such impact.
Practical implications
The authors can only observe a point in time and with that they do not know how long the individual has been obese.
Originality/value
The methodology adopted in the work is recent; moreover, studies on the effects of obesity on the labor market are still recent in Brazilian research.

Abstract
Purpose
The purpose of this paper is to understand the meaning and operationalization of food supply chains in the context of the UK and India.
Design/methodology/approach
The paper follows the systematic literature review approach. The paper examines 99 articles published in peer-reviewed-journals from 1995 to 2017.
Findings
Findings reveal that food supply chain literature is explored along themes of procurement, food processing, innovation, traceability, safety, environment and sustainability, food policy, quality, health, consumer behavior and packaging. Within these themes, the UK researchers have primarily addressed vertical integration, coordination, safety, competitiveness and transparency and information technology. Indian researchers have focused on issues such as consumer perceptions, retail format choice, organic, health and wellness products. An empirical category is the most popular approach. The survey method is the most popular approach followed by the single case studies.
Research limitations/implications
The paper contributes to the body of knowledge by presenting a unified synthesis of articles dealing with the food supply chain in the bilateral context of the UK and India.
Practical implications
The policy makers could use findings for conceptualization of complementarities and possible food supply chain networks.
Social implications
Food processing activities may have potential to provide sustaining livelihoods to around sixty percent of the Indian population which depends on the agriculture. In the bilateral context, the UK may also get a reliable and cost competitive partner to meet its food import needs. This will help the UK to focus more on its service-led economy which, in turn, may create more jobs.
Originality/value
The paper highlights the contextual issues of both the countries and presents opportunities for future collaboration.

This paper investigates causal connections between childhood adversities and chronic health problems among Brazilians aged 50 and over.
Abstract
Purpose
This paper investigates causal connections between childhood adversities and chronic health problems among Brazilians aged 50 and over.
Design/methodology/approach
The study employed propensity score matching (PSM) using data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil). The sample analyzed consisted of two groups: individuals who experienced childhood adversities and those who did not.
Findings
Individuals who experienced nutritional and health adversities in childhood are more likely to develop health problems at older ages, such as high blood pressure, osteoporosis, asthma, rheumatism and chronic column problems in adulthood.
Research limitations/implications
The main limitation of this research is the use of a cross-sectional database, which poses challenges such as recall bias and sample selection bias.
Practical implications
The study reinforces the importance of investing in childhood to mitigate the severity of chronic diseases in later life.
Social implications
The findings support increased investment in childhood nutritional programs and healthcare, which can improve human capital and reduce long-term medical and economic losses due to chronic diseases.
Originality/value
While economic research on medical issues is abundant in developed countries, where a predictable causal relationship between childhood adversities and chronic health problems in later life has been established, there is a lack of depth in this research in developing countries, particularly in Brazil. This study aims to contribute to health policy formulation, the development of medical facilities and research in Brazil.

Abstract
Purpose
Meat is a crucial source of protein and other nutrients for human health. However, excessive consumption of meat products is not advisable due to their elevated sodium and animal fat levels. Hence, there is a strong recommendation for reducing sodium and fat content in meat products. This study aims to delve into the current sodium, total and saturated fat content of meat products in the Brazilian market.
Design/methodology/approach
A total of 1,600 products underwent analysis.
Findings
The highest sodium concentrations were identified in jerked beef (5.48 g/100 g), charqui (5.21 g/100 g) and salted pork meat (2.58 g/100 g). In contrast, the highest total and saturated fat levels were observed in bacon (35.33 and 12.50 g/100 g), salami (26.00 and 9.25 g/100 g) and pork coppa (22.00 and 9.75 g/100 g). Most meat products were categorized as medium in terms of sodium (77.75%), total fat (52.93%) and saturated fat (48.25%). However, many meat products exhibited high total and saturated fat levels.
Originality/value
This study represents the first comprehensive examination of the sodium, total fat and saturated fat content listed on the labels of many meat products in Brazil.

Abstract
Purpose
The purpose of this study is to examine the functional relationships among terminal and instrumental values, environmental consciousness and behavioral intentions for green products in India in light of the value–attitude–behavior framework.
Design/methodology/approach
This study adopts a hypo-deductive research design. A conceptual model was developed to relate the terminal and instrumental values to environmental consciousness and behavioral intentions, which are substantiated with a comprehensive literature review. Covariance-based structural equation modeling was used along with Anderson and Gerbing’s two-step research approach to measure the dimensions of the measurement model, as well as the specifications of the structural model.
Findings
The findings of the research indicate that terminal and instrumental values significantly influence environmental consciousness, and environmental consciousness has a significant influence on behavioral intentions. Instrumental value shows a greater influence on environmental consciousness and behavioral intentions, rather than terminal value. Furthermore, this study discloses that environmental consciousness acts as a partial mediator while establishing a link between instrumental/terminal value and behavioral intentions.
Research limitations/implications
The present research is based on two distinct forms of human values, namely, terminal values and instrumental values. The study found that consumers who favored instrumental values to terminal values revealed a tendency to frame confused and incoherent judgments on environmental issues.
Practical implications
The study will help green marketing practitioners understand the important role of values, that is, both terminal and instrumental values, in promoting environmental consciousness and behavioral intentions for green products. The findings of the study will facilitate decision-making processes in relation to marketing for green product consumers in the Indian context.
Social implications
Values are the guiding forces for human behavior, both socially and individually. Moreover, values have a long-lasting impression on consumers in varied forms. This study will pave the way forward by contributing to the societal understanding of consumer values within the realms of human values for green marketing, green consumerism and sustainable businesses.
Originality/value
The paper is the first attempt of its kind to explore the relationships among two distinct forms of values that are the foundation of human values, namely, terminal and instrumental values, and their effect on environmental consciousness and behavioral intentions for green products in the Indian market. The paper is unique in understanding factors contributing to green marketing beyond consumer values and differs from previous research in specifying the significance of human values.
