1. Sugar derived from genetically modified sugarcane
Abstract Sugar is an ancient food and currently one of the most used ingredients in human nutrition and in the food industry. In tropical regions, sugar is produced mainly from sugarcane, while temperate countries produce sugar preferably from sugar beets. Due to its widespread use, the forthcoming adoption of genetically modified (GM) sugarcane varieties ma

2. Risk perception related to food
Abstract There is no human activity that is risk free, including those most trivial and essential for survival, such as eating. Various factors impact the risk perception of a population, such as whether the risk is voluntary, known, brings some benefits or whether the information about the risk is provided by sources seen as trusted. Furthermore, regional a

3. Energy embodiment in Brazilian agriculture: an overview of 23 crops
The amount of energy required to produce a commodity or to supply a service varies from one production system to another and consequently giving rise to differing levels of environmental efficiency. Moreover, since energy prices have been continuously increasing over time, this energy amount may be a factor that has economic worth. Biomass production has a v

4. Acceptance of a food of animal origin obtained through genetic modification and cloning in South America: a comparative study among university students and working adults
AbstractWith the aim of comparing the acceptance of milk obtained from cloned, genetically modified (GM) and conventionally bred cows among working adults and university students, and identifying and characterizing typologies among both subsamples in terms of their preferences, a survey was applied to 400 people in southern Chile, distributed using a simple

5. Detection of genetically modified organisms in soy products sold in Turkish market
PCR-based technique for GMO detection is the most reliable choice because of its high sensitivity and specificity. As a candidate of the European Union, Turkey must comply with the rules for launching into the market, traceability, and labeling of GMOs as established by EU legislation. Therefore, the objective of this study is to assess soybean products in t

7. Detection of genetically modified maize events in Brazilian maize-derived food products
The Brazilian government has approved many transgenic maize lines for commercialization and has established a threshold of 1% for food labeling, which underscores need for monitoring programs. Thirty four samples including flours and different types of nacho chips were analyzed by conventional and real-time PCR in 2011 and 2012. The events MON810, Bt11, and

8. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

9. Avaliação de resíduos de glyphosate e AMPA, produtividade, teor de óleo, conteúdo de proteína bruta e aminoácidos na soja (Glycine max (L.) Merrill) resistente ao glyphosate / Determination of glyphosate and AMPA residues, yield, oil, crude protein content and amino acids in glyphosate-resistant soybean (Glycine max (L.) Merrill)
O objetivo deste trabalho foi avaliar resíduos de glyphosate e AMPA, produtividade, teor de óleo, conteúdo de proteína bruta e aminoácidos na soja (Glycine max (L.) Merrill) resistente ao glyphosate (SRG) após a aplicação de formulações deste herbicida. Foram desenvolvidos experimentos em replicata (E1 e E2) em lísimetro sob condições de campo e

10. Acúmulo de ricina em sementes de mamona e silenciamento do gene em plantas geneticamente modificadas
Castor bean (Ricinus communis L.) is an oilseed of great economic and social importance. The oil extracted from its seeds is used in biodiesel production and as raw material for chemicals, cosmetics and lubricants. Besides the oil extracted from the seeds, their production chain generates side-products, which can be used as organic fertilizer of good quality

11. Biological, systemic and reproductive evaluation in Wistar rats feed on genetically modified soybean resistant to the glyphosate. / Respostas biológica, sistêmica e reprodutiva de ratos Wistar alimentados com soja geneticamente modificada resistente ao glifosato
The most cultivated genetically modified plant in Brazil is the soybean [Glycine max (L.) Merr.] resistant to the systemic herbicide glyphosate. There are 12.3 millions of cultivated hectares. This soybean was obtained through the introduction of the gene that codes for the 5-enolpyruyilshikimic-acid3-phosphate synthase enzyme, (EPSPS, E.C 2.5.1.19, CP4), of
