Deacidification of Soybean Oil by Ion Exchange

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)This work investigated the deacidification of soybean oil by ion exchange using a fixed bed loaded with the strong anionic resin Amberlyst A26 OH. Degummed soybean oil was dissolved in isopropanol and the deacidification process was studied according to an experimental design based on two factors, the feed flow rate and its content of free fatty acids. The responses of interest were the solute recovery efficiency and the bed utilization efficiency, both calculated from breakthrough curves. Oil samples before and after deacidification by ion exchange, as well as samples deacidified in the industrial plant by the chemical method, were characterized according to the usual indexes for quality and identity. The results revealed that the flow rate was an important and statistically significant factor with 95 % of confidence. The deacidification by ion exchange decreased the oil acidity and also removed undesirable compounds, such as phospholipids and peroxides. However, a decrease in the concentration of tocopherol was also observed.61233353344Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)FAPESP [2008/56258-8+2009/54137-1]CNPq [304495/2010-7+131182/2010-2

Educação em saúde a partir de círculos de cultura Educación en salud basada en círculos de cultura Health education based on culture circles

O estudo tem os objetivos de sistematizar, mediante Círculos de Cultura, uma proposta de (re)construção das ações de educação em saúde que articule as competências necessárias aos(as) enfermeiros(as) de PSF para uma prática de educação em saúde reflexiva e crítica e realizar uma auto-avaliação dos Círculos. Constitui uma Pesquisa-ação, onde a pesquisadora fundamentada no "Método Paulo Freire" é animadora de debates em oito Círculos de Cultura. Participaram dez enfermeiras. Os Círculos propiciam o exercício da consciência política, indispensável ao processo de "empowerment" do profissional de saúde no exercício de sua competência sociopolítica. A realização de Círculos de Cultura propicia uma relação de cumplicidade entre os profissionais de saúde e os grupos comunitários com as ações de promoção da saúde.<br>El estudio tiene como objetivo sistematizar, con las participantes de los Círculos de Cultura, una propuesta de (re)construcción de las acciones de educación en salud que articule las competencias necesarias a los(as) enfermeros(as) del PSF para una práctica de educación en salud reflexiva y crítica.

It is constituted of a research action, where the researcher based in "Paulo Freire Method" is encouraging debates in eight Culture Circles having the participation of ten nurses. The Circles give them the training of a political conscience , essential to the process of " empowerment " of the health professional in practicing his socio-politics competence. The proposal of achieving the Culture Circles establish a link of complicity between health professionals and communitarian groups with the actions of health promotion
