Living organisms are constantly subjected to the action of free radicals, which are one of the causes of oxidation reactions, because they have on free electron, what makes it very reactive. They are products of organism reactions or they are produced by exogenous factors, such as tobacco. Fatty acids are the most vulnerable target, and may suffer lipid peroxidation, what affects the cell structure. Cardiovascular diseases, cancer and diseases of aging are occurrence of these reactions in the organism related. The aliments are also subjected to suffer oxidation reactions, what make them unfit for consumption and decreasing the useful life. Synthetics antioxidants are used as aliments preservatives, but they present some toxicity for the organism. Studies for the utilization of natural antioxidants have gained more importance in recent decades, due to the conservation potential and low toxicity. Phenolics compounds are largely present at the vegetable kingdom and they present high antioxidant potential due to the neutralization and kidnapping of free radicals capacity. These compounds are used by the industry at the aliments conservation, specially the phenolics acids. The consumption of aliments rich in phenolic compounds, such as teas, wines and fruits are low incidence of degenerative diseases related. This study consists in a bibliographic revision that covers these compounds importance in diet and at the food conservation, and the methodologies and difficulties in the extraction process due to variety of molecules of this group.

This article presents part of a broader research and seeks to elucidate the process of setting up a Socio-scientific Issue in a group of teachers at a public school. Assuming that a Socioscientific Issue must aggregate those involved in the educational process in situations of dialogue, argumentation and construction of a positioning, we understand that the recognition of the controversy or of the legitimacy of the theme in the context at stake is crucial to achieving the desired goals. Thus, starting from subsidies from the Critical Theory of Society, we characterize the process of setting up a Socio-scientific Issue among teachers as an exercise of unveiling the concrete reality, listing problematic, controversial and open to criticism aspects of Science and Technology. Thus, the Socio-scientific Issue is listed out in the group as soon as it is established a polyphonic dialogue where all participants stand, recognize the fertility of the themefor the intendededucational context and can speak of it with propriety.
