| A simple and low cost method to determine volatile contaminants in post-consumer recycled PET flakes was developed and validated by Headspace Dynamic Concentration and Gas Chromatography-Flame Ionization Detection (HDC-GC-FID). The analytical parameters evaluated by using surrogates include: correlation coefficient, detection limit, quantification limit, accuracy, intra-assay precision, and inter-assay precision. In order to compare the efficiency of the proposed method to recognized automated techniques, post-consumer PET packaging samples collected in Brazil were used. GC-MS was used to confirm the identity of the substances identified in the PET packaging. Some of the identified contaminants were estimated in the post-consumer material at concentrations... |

| This study aimed at the technical-economical evaluation of implanting some vegetal-oil extraction units in order to insert the family agriculture into bio-diesel production chain. Three project models (arrangements) for vegetal-oil extraction units at different sizes were proposed, using extraction by pressing and mixed extraction (extracting by either pressing or solvent) and different raw materials (castor-oil and soybean). For the size analysis, the oil production scales between 50/60 tons/day were used with real market data concerning investments, inputs prices of the process, raw materials and vegetal oil. For the economic analyses, the software BioSoft was used. The BioSoft is a program for supporting the decision-making process, which was developed... |

| Four different detergents, ASB 14, SB 3-10, CHAPS and Triton X100, were utilized to determine the optimal detergent for the solubilization of membrane proteins from the phytopathogenic bacterium Xylella fastidiosa. These proteins were differentially solubilized in distinct buffers containing the detergent and subjected to bidimensional electrophoresis within the non-linear pH range of 3-10. The detergents ASB 14 and SB 3-10 were the most effective revealing 221 and 157 spots, respectively. CHAPS and Triton X100 were less effective and revealed only 72 and 43 spots, respectively. MALDI-TOF tryptic peptide mass fingerprinting of 18 excised proteins from the ASB 14 treatment revealed that 83% were membrane proteins and that the theoretical efficiency of... |

| O aproveitamento de coprodutos agroindustriais reduz o custo de produção e a geração de resíduos. O objetivo deste trabalho foi caracterizar e avaliar o efeito da embalagem durante o armazenamento de farinha obtida da extração de óleo do mesocarpo de bacaba. Os frutos foram coletados no projeto Reca (Reflorestamento Econômico Consorciado e Adensado), Nova Califórnia, Rondônia, transportados para Embrapa Acre, secos em estufa a 50 °C, triturados e armazenados à temperatura ambiente média de 28 °C, por 120 dias, sob diferentes tratamentos: T1 = sem embalagem, T2 = embalagem aluminizada sem vácuo e T3 = embalagem aluminizada com vácuo. Após o armazenamento, as amostras foram avaliadas quanto à composição centesimal, pH, acidez, componentes de cor (coordenadas... |

| The analysis of the dissolved organic fraction of hydrothermal fluids has been considered a real challenge due to sampling difficulties, complexity of the matrix, numerous interferences and the assumed ppb concentration levels. The present study shows, in a qualitative approach, that Stir Bar Sorptive Extraction (SBSE) followed by Thermal Desorption - Gas Chromatography - Mass Spectrometry (TD-GC-MS) is suitable for extraction of small sample volumes and detection of a wide range of volatile and semivolatile organic compounds dissolved in hydrothermal fluids. In a case study, the technique was successfully applied to fluids from the Rainbow ultramafic-hosted hydrothermal field located at 36 degrees 14'N on the Mid-Atlantic Ridge (MAR). We show that... |

| Abstract The present study aims to evaluate the influence of extraction methods on the quality of bioactive compounds and antioxidant capacity in Pterodon emarginatusVogel (sucupira) oils. The oils were extracted from the sucupira seeds by Soxhlet and by the extraction system of Bligh & Dyer. The oils were analyzed as to fatty acid profile, tocopherols, phytosterols, carotenoids, total phenolics, and total antioxidant capacity. The extraction by Soxhlet showed better yield of total lipids and was more efficient to extract tocopherols, phytosterols, and carotenoids, besides presenting better antioxidant activity by DPPH•. However, this method showed insufficient capacity to extract the polar lipid components of the sample, as evidenced by the low... |

| O cupuaçu é uma espécie nativa na região Amazônica que se encontra em estágio inicial de domesticação, apresentando ampla variabilidade genética para as diversas características. Contudo, poucos são os estudos que envolvem avaliações moleculares nesta espécie. A otimização de um protocolo para extração de DNA é pré-requisito básico para etapas subseqüentes da análise molecular. Com o objetivo realizar amplificação e melhoria da qualidade e quantidade de DNA obtido dessa espécie, o presente trabalho compara protocolos de extração de DNA do cupuaçu. Os protocolos utilizados foram o de Doyle e Doyle (1990), modificado por FIGUEIRA et al. (1997) com a utilização de proteinase K, e o Doyle e Doyle (1990), modificado por FERREIRA GRA TTAP AGLIA (1998)... |

| Abstract: This work aimed to evaluate nine strains of yeast, previously identified as good producers of lipids in honey medium, for selecting the most suitable strain for the production of lipids in cheese whey medium and compared two well known extraction methods of lipids from the culture medium. The highest yield of total lipids was 1.27 g.L-1 produced by Cryptococcus laurentii 11. A comparison was made between the two culture media: cheese whey and liquid YEPG, and two lipid extraction methods: Bligh and Dyer and Folch et al. for C. laurentii. The experiments were performed with 22 full factorial design using two factors and two levels. Lipid content was higher in cheese whey and there was no difference in the extraction methods statistically. The... |

| The effect of pre-treatment of mackery (Scomber scombrus) on oil recovery and quality was investigated. Fish oil was extracted using the screw expeller press after heat pre-treatment of the fish sample. The effect of cooking temperatures and cooking times was evaluated. It was observed that the oil yield has a positive relationship with cooking temperature. The oil yield increased with increasing cooking temperature at all the cooking times investigated and also increased with increasing cooking time from 5-15 minutes and then decreased for 20 minutes cooking time at all the cooking temperatures investigated. The results revealed that a highest yield of 22.8 % was obtained when the fish was treated at 90 0C cooking temperature for 15 minutes. The lowest... |
