Two Stages

Considering that the demand for food will increase by 70% by 2050, consuming insect-based foods appears as a protein alternative due to their nutritional quality and low environmental impact. However, there is a need to investigate the acceptance of these innovative foods, especially in traditional meat-eating markets, such as in Southern Brazil (land of the Gauchos). The purpose of this manuscript is to analyze consumers' attitudes toward innovative insect-based foods. The methodological procedures were divided into two stages. In the qualitative stage, 14 interviews were conducted regarding meat consumption habits. In the quantitative stage, a survey was carried out with 433 consumers. A factor and cluster analysis were performed, and two different groups of consumers were found. The results clearly show a segment with positive attitudes toward insect-based foods. This group had a low degree of neophobia. The products were perceived as not tasty and disgusting, but they were considered modern, with high nutritional value, positive, safe, and beneficial to the environment. Appearance, price, and packaging, combined with flavor, proved to be the attributes considered by consumers as the most important for their acceptance.

Lontra Longicaudis

A genetic study of the neotropical river otter Lontra longicaudis (Olfers, 1818), which has an unknown conservation status, was carried out at the Taim Ecological Station and the margins of the Vargas stream, Rio Grande do Sul, southern Brazil. Faecal samples were collected, and DNA was extracted using a silica-guanidine method. Five microsatellite loci were amplified using PCR with heterologous primers previously described for Lutra lutra (Linnaeus, 1758). Sixteen faecal samples out of 29 from Taim and 11 out of 14 from Vargas stream margins contained enough DNA for genetic analysis. A total of 49 different alleles were found at both localities, from which 18 were exclusively found in individuals from Taim and 17 were exclusives from Vargas individuals. The most common allele was the same at both locations for three loci (Lut715, Lut733, and Lut818). A high level of genetic diversity was found at both sites (NeTaim=4.1, HoTaim=0.299, HeTaim=0.681; NeVargas=4.9, HoVargas=0.355, HeVargas=0.724), being higher at the Vargas stream site. A high and significant level of heterozygote deficiency was observed at most loci according to the χ2 test. The homogeneity χ2 test (P<0.001) showed that there were significant differences in the allele frequencies between the two locations. Genotyping for more than one locus was possible in 81.5% of samples, from which only 37% were possible to genotype for more than three loci. A low degree of relatedness was found among individuals from Taim (R=0.055±0.310), but an even lower value of relatedness was found at the Vargas site (R= -0.285±0.440). The significant degree of differentiation (I=0.890; F ST=0.059) found between Taim and Vargas individuals suggests that there is more than one population of otters in the southern extreme of Brazil, which probably are associated with the water body systems found in this region, the Mirim and the Caiuvá/Flores/Mangueira Lagoons. The high genetic diversity and low relatedness found at the Vargas stream, lead us to believe that the Vargas stream may be acting as a corridor between these water bodies for otter dispersion.

Salinity Levels

The comparative responses of two broccoli cultivars (Brassica oleraceavar. Italica, cv. Parthenon and cv. Naxos) to a 15 d exposure to different NaCl levels were investigated. Salinity led to increased concentrations of Na+and Cl−ions in both cultivars, a disruption of the endogenous minerals levels in the shoots and roots—that varied with the cultivar and salt concentration—and decreases in the osmotic potential (Ψπ), root hydraulic conductance (L0), and stomatal conductance (Gs). The reduced biomass of Naxos at moderate NaCl indicates greater sensitivity to salinity, compared with Parthenon. Parthenon accumulated more soluble sugars, for osmotic adjustment, whereas Naxos accumulated proline, which gave the two cultivars differing nutritional characteristics. The total glucosinolates (GSLs) content was not affected by salinity in Parthenon while it decreased significantly in Naxos as a consequence of the decrease in the indole GSL. However, Naxos accumulated more aliphatic GSLs under salt stress than Parthenon, which confers on this cultivar a greater nutritional value when cultivated under salinity.These results suggest that, at distinct salinity levels, each broccoli cultivar adopts a specific strategy, indicating the crucial role of the genetic background on the organoleptic and nutritional properties that each cultivar acquires.

And Cluster Analysis

Purpose The purpose of this paper is to characterize the consumers of mezcal in México based on their motivations, identifying different groups of consumers and their demographic characteristics. Design/methodology/approach A questionnaire based on the Food Choice Questionnaire was applied to 310 consumers: 154 directly to mezcal consumers in three “mezcalerías” (mezcal bars) and 156 through five social networking communities of mezcal consumers. The data obtained were analysed using multivariate statistics, factor and cluster analysis. Findings The results show that the search for tradition is the determining buying motivation, whereas quality seals do not exert a significant influence. Four profiles of mezcal consumers can be identified according to their consumption patterns: consumer linked to the territory, traditional consumer, consumer in transition and social consumer. The predominant demographic characteristics in the four consumer groups described a male, between 20 and 39 years old, single, childless, with professional education and employed. The overall results reveal a consumer who shares the quality criteria established by mescal-producing communities and is strongly interested in traditionally processed drinks. Originality/value In México, there are two important distilled drinks, tequila and mezcal. There is ample research on the first one, but there is less research on mezcal, despite it has an annual increase of 45 per cent in consumption. Most of the research work has been focused on aspects of diversity, sustainability and productivity, but there are not studies on the factors that affect mezcal consumption. Thus, this paper aims to characterize the consumers of mezcal, based on their motivations.

The Creation

This chapter explores how marketing uses the creation and perpetuation of myths to reinforce demand for meat amongst mainstream consumers. It explores advertising misinformation including with regards the place of meat in our culture, its nutritional value, its association with affluence, masculinity and the benefits of small-scale production. The power of marketing is within the context of whether marketing has a role to play in decreasing rather than perpetuating meat-consumption.
