Uma análise empírica sobre as preferências do consumidor brasileiro de cervejas artesanais

Um dos produtos mais consumidos do mundo vem passando por grandes transformações, e a cerveja que conhecemos como tipo Pilsen (Light Lager) deixou de ser opção única nas prateleiras. Dado o potencial de crescimento do setor no Brasil, o objetivo deste trabalho é mapear as preferências do consumidor de cerveja artesanal, usando técnicas de preferência declarada, a partir da aplicação de questionários que convidam o entrevistado a elencar suas preferências diante das combinações dos atributos Cor, Paladar, Aroma e Álcool. A partir da estratificação da amostra em Idade e Experiência, os resultados indicam que Paladar, seguido da Cor e, por último, o Aroma são os atributos mais relevantes para o entrevistado Experiente, enquanto o Não Experiente atribui maior peso à Cor, seguida do Paladar, sendo o Aroma um atributo irrelevante em suas escolhas. O atributo Álcool revelou-se insignificante em todas as estratificações realizadas.

Respiratory and storage behavior of fresh cut 'Tommy Atkins' mango

The respiratory and storage behavior of fresh cut 'Tommy Atkins' mango, naturally ripened (NR) or with use of ethylene (RE), were studied. Fruits were selected, washed and disinfected (200 mgCl.L-1) and stored for 12 hours at 10°C. After this period, they were processed under hygienic conditions at 10°C, packaged in polyethylene terephthalate (PET) trays or in styrofoam trays wrapped with stretchable polyvinyl chloride (PVC) film and stored for up to 15 days at 3°C. The products were evaluated regarding the evolution of internal atmosphere in the packing (O2 and CO 2), development of weight, appearance, shelf life and consumer acceptability. The respiratory rate was measured before and after processing every two hours. The yield of 'Tommy Atkins' mango to produce fresh cut product was 48.09±0.95%. Increase of the respiration rate of both mango samples was verified one hour after the preparation (NR = 17.75 mL CO 2.kg-1.h-1; RE = 28.29 mL CO 2.kg-1.h-1), followed by stabilization at 3.76 and 8.07 mL CO2/kg.h, respectively. The percentage of O2 in packages was stable in all treatments, 15-20% in PVC trays, 18-20% in PET tray. The percentage of CO2 was steady around 1.5-2.5%. The products lost fresh mass during the storage, from 0.06% to 0.30% for PET trays and from 0.15% to 1.61% for trays covered with PVC. The appearance was considered appropriate for commercialization until the 13th day, whereas product from mangoes ripened with application of ethylene was for 11 days, presenting browning in the external surface. The naturally ripened mango presented the best flavor and consumer preference in relation to the mango ripened with application of ethylene for 11 days of storage. The control of hygienic conditions during the production and storage was good and with safety for until 10 days.

Aplicação do método desirability para otimização de processo com múltiplas respostas

Currently, the competition between organizations in the pursuit of consumer preference has become increasingly fierce. In addition, consumers have become increasingly demanding due to high speed with which innovations occur, leaving the companies meet and sometimes surpass those expectations In this context, there is the necessity to use methods as mathematical models capable of dealing with the optimization of multiple responses simultaneously. In this context, this study presents an application of techniques of Design of Experiment in a machining process of a NIMONIC 80 alloy, a “superalloy” that has thermal and mechanical properties that make its machining difficult and in order to do this, the Desirability Function was used. As they are determining conditions in the machining capability of the alloy, the roughness and the cutting length were considered as variable settings, and the factors that can influence them are cutting speed, feed rate, cutting depth, inserts type and lubrication. The analysis of the result pointed out how was the influence of all factors on each response and also showed the efficiency and reliability of the method

Fattori relazionali e di coordinamento nella filiera agro-alimentare: una valutazione della governance relazionale nel settore lattiero caseario sardo

Characteristics of modern food demand force retailers to acquire more information about product process along the food supply chain to ensure that product are in accordance with consumer preference. Therefore, the product process involves more information flows between buyer and supplier which requires collaborative efforts. These changes translate into several studies on the inter-organizational relationship in agri-food systems. Studies on inter-organizational relationships have been conducted in various academic disciplines, including sociology, psychology, law, economics, marketing, management, and combination of these. Inter-organizational relationships is an interaction between organizations which involved firms horizontally, as well as, vertically. In this study we deal with vertical, buyer-seller relationship which are sometimes referred to chain relationships. We define vertical business relationship in the agriculture-food based sector as “agri-food chain relationships”. The focus is on sustainable inter-organizational relationships in a way that they can be scientifically investigated. We study characteristics which ensure that a relationship is long-lasting and rewarding for all involved parties in the sardinian dairy. We test the theoretical model using structural equation modeling. The results suggest that the most important determinant for the relationships is technology and the price isn’t significant for the relationship governance.

A hierarquia de preferência do consumidor em decisões de investimento financeiro

A literatura acadêmica sobre o comportamento do investidor financeiro é bastante escassa. A pesquisa sobre o processo de decisão, em geral, aborda tradeoffs na aquisição de produtos e pouco se discute o processo de decisão de investimento. Esta tese pretende contribuir para a redução deste gap ao discutir fatores determinantes para a tomada de decisão do investidor pessoal em produtos financeiros. A decisão de investimento é complexa, envolve, entre outros, o tradeoff entre renunciar o consumo presente pela possibilidade de maior bem estar no futuro. Adicionalmente, em muitas situações, existe possibilidade real de perda dos recursos financeiros investidos. Para investigar os percursos desta decisão foram realizadas entrevistas em profundidade com executivos ligados ao setor de fundos de investimento e ao de distribuição de produtos de investimento dos maiores bancos brasileiros atuantes no segmento de varejo. Os conhecimentos recolhidos e a revisão de literatura efetuada subsidiaram a elaboração do questionário de pesquisa aplicado em plataforma web junto a potenciais investidores. Os atributos rentabilidade, possibilidade de perda (proxy de risco), liquidez, taxa de administração e recomendação do gerente foram identificados como os mais relevantes para a decisão do investidor. Para construção dos estímulos e decomposição da utilidade da decisão foi utilizada a técnica conjoint based choice (CBC) que simula uma decisão real. Os resultados apontaram ser a recomendação do gerente o atributo mais importante para a formação da preferência por uma alternativa de investimento, resultado que, por si só, indica que fatores não racionais exercem influência na decisão. Estudou-se, então, o impacto da aversão ao risco e do estilo cognitivo do investidor. Os resultados denotam que os mais avessos e os mais intuitivos são mais suscetíveis à recomendação do gerente, mas que seus efeitos são independentes entre si. As evidências sugerem que os mais intuitivos utilizam o gerente para alcançar conforto cognitivo na decisão e que os mais avessos para mitigar a sensação de risco associada ao produto. Uma análise de cluster indicou ser possível segmentar a amostra em dois grupos, um mais propenso à recomendação do gerente e outro aos atributos do produto. A recomendação do gerente mostrou ser o atributo mais forte na distinção dos grupos. Os resultados indicam que uma segmentação de mercado baseada na propensão à recomendação do gerente pode ser efetiva para direcionar a construção de uma estratégia de relacionamento que busque incrementar os resultados de longo prazo.

Mapping the mind for the modern market researcher

Purpose - To describe the utility of three of the main cognitive neuroscientific techniques currently in use within the neuroscience community, and how they can be applied to the emerging field of neuromarket research. Design/methodology/approach - A brief development of functional magnetic resonance imaging, magnetoencephalography and transcranial magnetic stimulation are described, as the core principles are behind their respective use. Examples of actual data from each of the brain imaging techniques are provided to assist the neuromarketer with subsequent data for interpretation. Finally, to ensure the neuromarketer has an understanding of the experience of neuroimaging, qualitative data from a questionnaire exploring attitudes about neuroimaging techniques are included which summarize participants' experiences of having a brain scan. Findings - Cognitive neuroscientific techniques have great utility in market research and can provide more "honest" indicators of consumer preference where traditional methods such as focus groups can be unreliable. These techniques come with complementary strengths which allow the market researcher to converge onto a specific research question. In general, participants considered brain imaging techniques to be relatively safe. However, care is urged to ensure that participants are positioned correctly in the scanner as incorrect positioning is a stressful factor during an imaging procedure that can impact data quality. Originality/value - This paper is an important and comprehensive resource to the market researcher who wishes to use cognitive neuroscientific techniques.

An Evaluation of Three Nutrition Labeling Formats for Restaurant Menus

This study evaluated three menu nutrition labeling formats: calorie only information, a healthy symbol, and a nutrient list. Daily sales data for a table-service restaurant located on a university campus were recorded during a four-week period from January to February 2013 to examine changes in average nutritional content of the entrees purchased by customers when different nutrition labels were provided. A survey was conducted to assess the customers’ use of nutrition labels, their preferences among the three labeling formats, their entree selections, their cognitive beliefs with regard to healthy eating, and their demographic characteristics. A total of 173 questionnaires were returned and included in data analysis. Analysis of Variance (ANOVA) and regression analyses were performed using SAS. The results showed that favorable attitudes toward healthy eating and the use of nutrition labels were both significantly associated with healthier entrée selections. Age and diet status had some effects on the respondent’s use of nutrition labels. The calorie only information format was the most effective in reducing calories contained in the entrees sold, and the nutrient list was most effective in reducing fat and saturated fat content of the entrees sold. The healthy symbol was the least effective format, but interestingly enough, was most preferred by respondents. The findings provide support for future research and offer implications for policy makers, public health professionals, and foodservice operations.

Antioxidant and angiotensin-converting enzyme inhibitory activity of eucalyptus camaldulensis and litsea glaucescens infusions fermented with Kombucha Consortium

Physicochemical properties, consumer acceptance, antioxidant and angiotensin-converting enzyme (ACE) inhibitory activities of infusions and fermented beverages of Eucalyptus camaldulensis and Litsea glaucescens were compared. Among physicochemical parameters, only the pH of fermented beverages decreased compared with the unfermented infusions. No relevant changes were reported in consumer preference between infusions and fermented beverages. Phenolic profi le measured by UPLC MS/MS analysis demonstrated signifi cant concentration changes of these compounds in plant infusions and fermented beverages. Fermentation induced a decrease in the concentration required to stabilize 50 % of DPPH radical (i.e. lower IC50). Additionally, it enhanced the antioxidant activity measured by the nitric oxide scavenging assay (14 % of E. camaldulensis and 49 % of L. glaucescens); whereas relevant improvements in the fermented beverage were not observed in the lipid oxidation assay compared with unfermented infusions. The same behaviour was observed in the inhibitory activity of ACE; however, both infusions and fermented beverages had lower IC50 than positive control (captopril). The present study demonstrated that fermentation has an infl uence on the concentration of phenolics and their potential bioactivity. E. camaldulensis and L. glaucescens can be considered as natural sources of biocompounds with antihypertensive potential used either as infusions or fermented beverages.
