OS ALIMENTOS TRANSGÊNICOS NA AGRICULTURA BRASILEIRA: EVOLUÇÃO E PERSPECTIVAS AgEcon
Almeida, Gustavo Calixto Scoralick de; Lamounier, Wagner Moura.
The transgenic is a genetically modified organism or culture (OGM) that contains a gene that was artificially inserted, instead of having acquired naturally for pollination as they are for the conventional cultures. The “new agriculture “ based on this kind of products, points to a smaller degradation of the soils and of the environment, with reduction of the production costs and of the final prices for the consumer. Though your effects about the human health are still ignored and for that same reason, several restrictions to that type of food have been imposed. In that sense, this work sought to enlarge the discussion on that product type, discussing the possible environmental, economical and biological impacts of the transgenic use. The work is concluded...

Preferences for sunflower oil produced conventionally, produced with nanotechnology or genetically modified in the Araucanía Region of Chile Ciencia e Investigación Agraria
Schnettler,Berta; Crisóstomo,Gloria; Mills,Natally; Miranda,Horacio; Mora,Marcos; Lobos,Germán; Grunert,Klaus G.
In light of the increasing use of nanotechnology in food production, consumer acceptance of sunflower oil produced with nanotechnology or from genetically modified (GM) plants and the conventionally produced raw materials available in Temuco (Araucanía Region, Chile), market segments were differentiated with respect to their acceptance of nanotechnology and characterized according to their sociodemographic characteristics and food neophobia level. To achieve this aim, a survey was administered to 400 people. Using a conjoint analysis, the brand (33.6%) and production system (32.6%) were determined to be more important than the price (19.2%) and health certification (14.6%); national brands, produced conventionally with a health certification seal and sold...

Semiquantitative analysis of genetically modified maize and soybean in food Electron. J. Biotechnol.
Cazzola,María Laura; Petruccelli,Silvana.
The aim of this study was to analyze quantitatively the presence of genetically modified organism in food with different composition and degree of processing. Total DNA was extracted by Dellaporta's method and GMO analysis was performed using two consecutives PCR reactions with specie specific primers (IVR and LE), screening primers (35S) and transgen specific primers (CRY and EPSPS). The quantification within the sensitivity establish by the EU was possible only in some foods (ice-cream, flours, soybean isolates and concentrates, starch). Samples with high lipid content or subjected to intense thermal treatments (such as some snacks, mayonnaise, creamy soup) could not be amplified mainly due to the presence of PCR inhibitors. Therefore the method was...

The role of biotechnology in agricultural production and food supply Ciencia e Investigación Agraria
Cano Estrada,Araceli; Vélez Díaz,Daniel; Morgado Hernández,Carlos Alberto.
Over the past several decades, technological developments and modernization have grown concomitantly.For example, advances in biotechnology have been used as a tool to increase food production. Specifically, advances in genetic engineering have made possible the manipulation of crops to increase yield, guaranteeing food supplies for the increasing world population. However, transgenic crops have not been well received by all members of society, and there is still uncertainty about their social benefits and the possible implications to human health. Additionally, the benefits of agricultural modernization have favored only developed countries, whereas people living in developing and underdeveloped countries suffer rampant hunger, malnutrition and poverty....
