Goat's milk is recommended for people afflicted with cow milk intolerance and gastro-intestinal disorders. frozen yogurt was elaborated with 1% prebiotic (inulin), 0.25% starter culture (Streptococcus thermophilus and Lactobacillus bulgaricus) and 0.25% probiotic culture (Bifidobacterium animalis and Lactobacillus acidophilus) to verify probiotic potential (after 7 and 120 days of storage), physical-chemical quality and sensorial acceptance. During storage viable cells were reduced, mainly probiotic bacteria. Nevertheless, the product showed probiotic potential because of B. animalis and L. acidophilus sum, which reached the minimum desirable until the end of storage. Values of total dry matter (26.6±0.2%), protein (3.0±0.3%), fat (2.6±0.1%), pH (5.5±0.01) and acid lactic (0.2±0.01%) were similar to those descript by other researches for the same product. Sensorial evaluation was realized by 50 untrained panelists, with a 7- point hedonic scale and intention to purchase. The product received good scores for global appearance, color, aroma and taste. Texture and residual taste had lower acceptance rates. The intent to purchase showed that 61% of panelists asserted to buy the product against 39%, who would not buy it. Accordingly, this research showed the feasibility of elaborating the goat's milk frozen yogurt with addition of pre- and probiotics.

The aim of this study was to evaluate the changes in the lipid profile, especially in conjugated linoleic acid (CLA), in 12 cream cheese batches with different prebiotic (inulin) and probiotic (Bifidobacterium animalis and Lactobacillus acidophilus) concentrations stored for 45 days at 8 ± 0.5 °C and analyzed every 15 days. A Central Rotational Composite Design was used to establish the prebiotic and probiotic concentrations. The effect of the pre- and probiotic concentrations on CLA contents (mg g−1 of fat) was verified by plotting the response surface. The linear, quadratic, and interaction coefficients of the multiple linear regression for both prebiotic and probiotics were not significant (p > 0.05). No significant changes were observed neither in the lipid profile nor in the CLA content among the different batches, in which fatty acid composition and CLA concentrations were similar to the milk used in the preparation of the cream cheese and also to the control batch.

In the pollution control laboratories, routine analyses for the characterization of effluents and reactors monitoring use concentrated solutions of H2SO4, containing heavy metals such as chromium, silver and mercury and organic compounds as phenol. The presence of these elements in the laboratory effluent can cause inhibition of the biological activity, especially in the anaerobic treatment processes due to the sensitivity of the methanogens to some chemical compounds. This work had as objective to characterize the effluent from the Federal University of Rio de Janeiro Chemistry School Environmental Technology Laboratory (LTA/UFRJ) and to determine which constituents of the effluent one would be inhibitors for anaerobic microorganisms in the treatment of the sewage generated in the campus. The effluent one presents a weekly average production of 43.4 L, with pH = 0.7, COD = 1350 mg/L, sulfate = 33500 mg/L; 28.2 mg Hg/L; 82.1 mg Crtotal/L; 30.8 mg Cu/L; 57.4 mg Fetotal/L; 16.2 mg Al/L and 2.44 g Na/L. The parameters analyzed presented high variability as the study was conducted in function of the analyses and researches carried out in that period. In experimental design performed, the elements sodium, chromium, phenol and sulfate, as well as the interactions sulfate-mercury and sulfate-sodium, were significantly more effective on the inhibition of the specific methanogenic activity (SMA). The effects of the other elements (cupper, mercury, aluminum and iron), analyzed alone and their interactions were not significant for a confidence level of 95% in the t-Student distribution. The results indicate the necessity of a specific treatment for the laboratory effluent, since universities must be examples of combating pollution and encouraging the environmental control.

INTRODUÇÃO: A prática regular de atividades físicas entre os níveis moderados e vigorosos tem relação inversa com a morbidade-mortalidade por doenças cardiovasculares e obesidade. É fundamental a identificação dos determinantes desta prática para serem propostas estratégias populacionais com vista à adoção de um estilo de vida fisicamente ativo. OBJETIVO: O presente estudo teve por objetivo determinar os fatores associados à prática de atividade física e ao sedentarismo na população adulta de Goiânia. MATERIAL E MÉTODOS: Trata-se de parte de um estudo multicêntrico, transversal, realizado na cidade de Goiânia/GO com amostra probabilística da população adulta atendida por linhas telefônicas fixas. Foram realizadas 2.002 entrevistas por meio de ligações telefônicas, definindo uma taxa de sucesso de 73,1%. A construção do banco de dados e as análises estatísticas foram realizadas com auxílio do aplicativo STATA, versão 8.0. RESULTADOS: O sedentarismo foi mais prevalente entre as mulheres (55,5%) que entre os homens (42,0%). A prevalência de hipertensão foi menor naqueles indivíduos que praticavam atividade física (p=0,0002). Em relação à atividade física no lazer, as mulheres foram mais inativas (79,3%) que os homens (66,9%). Houve relação inversa entre sedentarismo e escolaridade em ambos os sexos. CONCLUSÃO: Diante do quadro encontrado de alta freqüência de sedentarismo na população, sugere-se a implementação de estratégias de prevenção primária para melhorar o perfil de risco para doenças crônicas não transmissíveis.

abstract Emergence of a subject into the public agenda is a complex process that involves interpretation of the current reality, and consensus-building. This paper analyzes assessments made by managers, employees, health counselors and users of Brazil's Unified Health System (SUS) on the inclusion, exclusion or revision of components of the Brazilian National Health Promotion Policy (NHPP). The survey is part of the process of review of the NHPP. It is a descriptive study, carried out by web questionnaire in November 2013 – March 2014, with 1,545 participants. The questionnaire assessed the components of the first version of the NHPP – published in 2006 (objectives, guidelines, specific actions), and the central operational guidelines constructed for the second version (2014). The participants concluded that the components of the 2006 NHPP were adequate for the demands of the field in the current situation. However, they suggested some contributions to complement the Policy, including, among others: management and planning ; social determinants of health; intra-sectoral and intersectoral actions; equity; and development of personal skills. Participants emphasized professional education and the sustainability of actions in operational strategies. The contributions that the participants made do indeed point to the present needs in the field. We suggest that the NHPP should be evaluated in the various public spheres.

Health promotion policies and potential conflicts of interest involving the commercial private sector abstract This study analyzed potential conflicts of interest regarding the commercial private sector and health promotion policies, particularly their interface with the food and nutrition field in Brazil. The paper addresses the influence of international ideas in this process. The study analyzed the two separate publications of the Brazilian National Health Promotion Policy – of 2006, and of 2014 – and the international agreements that supported them. The method used was analysis of documents, with a categorization into the following dimensions and categories: In the dimension of the Ideas of health promotion, the focus items were the principles and the strategies proposed; In the dimension of conflicts of interest, these aspects were identified: the approach in the documents , relationships with the commercial private sector, and proposals referred to as 'public-private partnerships'. It was concluded that these policies still adopt a fragile approach in terms of conflict of interest. The debate is de-politicized when the asymmetries of power between the sectors involved in the public-private relationships are not made explicit, or when the practices of the commercial private sector that harm objectives, principles and values of health promotion policies are left out of account.

Este estudo de caráter descritivo configura uma das respostas de projeto de pesquisa e extensão de parceria entre docentes e acadêmicos de uma instituição de ensino superior e um grupo de agricultoras familiares, proprietárias de uma pequena agroindústria no estado de Goiás. O objetivo foi implementar boas práticas de fabricação de alimentos com vistas à adequação sanitária de produtos destinados à comercialização para o Programa Nacional de Alimentação Escolar. Realizou-se o diagnóstico in loco do processo de trabalho desenvolvido pelas agricultoras e propôs-se um programa de formação em
Boas Práticas Agrícolas e Boas Práticas de Fabricação. A formação ocorreu em treze encontros presenciais, totalizando 100 horas com diferentes abordagens metodológicas.
Realizou-se também pesquisa da vida de prateleira e elaboração da rotulagem nutricional dos produtos fabricados. As análises microbiológicas realizadas obedeceram aos padrões
microbiológicos da Agência Nacional de Vigilância Sanitária. Observou-se grande interesse das agricultoras nas atividades fundamentadas na construção coletiva. Definiu-se o prazo
de validade dos dezesseis produtos analisados e sua respectiva rotulagem. A atividade alcançou os objetivos propostos, como contribuição técnica e formação em boas práticas
a um grupo com potencial em atender às exigências sanitárias quanto à comercialização de alimentos oriundos da agricultura familiar para a alimentação escolar.
