Fisheries management is increasingly transitioning towards collaborative governance. Collaborative systems depend on stakeholders’ capacity to design and implement legitimate and scientifically robust management plans within collective action arenas. Here we propose that collaborative governance outcomes, in fisheries management, will benefit from using structured participatory decision making frameworks that enhance deliberative thinking among stakeholders. We tested our approach in the artisanal fishery of Chile, an important producer of marine resources. Recently in 2013, Chile made important changes to fisheries policies by creating multi‐sectorial management committees to manage de facto open access fishing areas. We applied a structured decision making framework to inform the restructuring of a management plan within a committee. As a result, we identified goals,objectives and indicators, including social, economic, biological and ecological dimensions; we explored tradeoffs, assessing the relative importance of the objectives; finally, we created scenarios and prioritized alternatives, reflecting on the interplay between self‐regulation and government control. Members of the management committee were able to rationalize the different steps of the framework and identify ways forward which highlighted the importance of self‐regulation in comparison to central authorities’ control. We concluded that structured decision making promotes spaces for rational analysis of alternatives costs and benefits. Promoting deliberative thinking in fisheries management can improve equity, legitimacy and sustainability of collaborative governance.
RESUMO:Os alimentos funcionais, como prebióticos e probióticos, garantem microbiota intestinal equilibrada e saudável e auxiliam na prevenção de doenças crônico-degenerativas, porém, pouco uso se faz desses alimentos devido à dificuldade de desenvolver produtos com características sensoriais atrativas e micro-organismos viáveis durante toda a vida útil do produto. O objetivo deste estudo foi desenvolver um sorvete de iogurte simbiótico enriquecido com polpa de açaí (Euterpe oleracea), elaborado com leite de búfala. Para o preparo do iogurte, o leite foi filtrado, desnatado e pasteurizado, e posteriormente, acrescido de 1% de prebiótico (inulina), 0,5% de cultura láctea (probiótico) e 8% de sacarose. Após, o iogurte foi dividido para obter quatro formulações de sorvete, F1 -com gordura vegetal e corante; F2 -com gordura vegetal sem corante; F3 -com nata e corante e F4 -com nata sem corante, para verificar a gordura mais acessível e o comportamento do consumidor em relação à adição de corante. Na avaliação das características físico-químicas, a F1 se destacou significativamente (p<0,05), em relação à qualidade nutricional. As formulações receberam notas médias acima de 6, para sabor, cor, textura, aroma e aparência global, de acordo com a escala hedônica de nove pontos, entretanto, as formulações com corante, F1 e F3, destacaram-se significativamente quando relacionadas a F2 e F4 (p>0,05). De acordo com a análise microbiológica os derivados estavam adequados para consumo humano. Assim, a elaboração do sorvete de iogurte enriquecido com açaí, é viável pela sua funcionalidade e valor agregado, com uso de nata ou gordura vegetal e adição de corante.Palavras-chave: Alimento funcional.

SUMMARY:Functional foods as prebiotics and probiotics, ensure balanced and healthy intestinal flora and help in preventing chronic degenerative diseases, however, little use is made of these foods because of the difficulty of developing products with attractive sensory characteristics and viable micro-organisms throughout the useful life of the product. The objective of this study was to develop a symbiotic yogurt ice cream enriched with açaí (Euterpe oleracea) prepared from buffalo milk. For the preparation of yoghurt, the milk was filtered, skimmed, pasteurized, and was increased by 1% prebiotic (inulin), 0.5% milk culture (probiotic) and 8% sucrose. After the yogurt was divided to get four ice cream formulations, F1 -with vegetable fat and dye; F2 -with vegetable fat without dye; F3 -with cream and dye and F4 -with cream without dye, to verify the most low fat and consumer behavior in relation to the addition of dye. In the evaluation of physico-chemical characteristics, F1 stood out significantly (p <0.05) in relation to nutritional quality. Formulations received above average grades 6 to flavor, color, texture, flavor and
O presente estudo teve como objetivo estimar o teor de colágeno em salsichas mediante a quantificação da hidroxiprolina. Amostras de salsichas produzidas por indústrias de pequeno, médio e grande porte, classificadas em função do mercado atendido, foram analisadas quanto ao seu conteúdo em hidroxiprolina, por técnica colorimétrica. O teor de colágeno foi significativamente diferente, baseado na quantidade de hidroxiprolina presente nas amostras de salsicha. As amostras que apresentaram o menor teor de colágeno foram as da indústria de médio porte (0,45%), seguida daquelas da indústria de grande porte (0,64%). As salsichas da indústria de pequeno porte apresentaram o maior teor de colágeno (0,89%). Esses resultados mostram que esse teste pode ser utilizado para classificação qualitativa de salsichas, em função dos teores de colágeno.
