| Abstract: The objective of this work was to determine the oil, protein, fatty acid, isoflavone, and anthocyanin contents in soybean grains of different breeding lines and maturity stages. Evaluations were performed for the chemical profiles of black- (BRM09-50995) and of yellow-seed-coat (BRM11-51428 and BRM08-50643) breeding lines, harvested at the R6 (immature seeds), R7 (physiological maturity), and R8 (full maturity) maturity stages. Oil and protein contents increased from the R6 to the R8 stage, and BRM11-51428 showed the highest protein content. Palmitic, stearic, and linolenic fatty acids were higher at R6, and linoleic and oleic acids were higher at R7 and R8, respectively. At the R8 growth stage, BRM11-51428 and BRM 09-50995 showed the highest... |

| Este trabalho teve como objetivo avaliar os níveis de resíduos de carbofuran utilizando métodos específicos de análise em amostras de bananas Musa spp submetidas a nove tratamentos distintos de controle químico. As aplicações do produto na plantação foram realizadas durante o cultivo segundo as Boas Práticas Agrícolas (BPA), evidenciando-se os seus efeitos nas concentrações de resíduos. Em seis destes tratamentos, efetuou-se a aplicação de 80g/planta do produto comercial diretamente no solo, de acordo com a recomendação do fabricante, e nos outros três tratamentos restantes, foram feitas aplicações com uma quantidade aproximadamente seis vezes menor (12g/planta) na muda desbastada. Após a colheita, os frutos foram analisados casca e polpa separadamente por... |

| ABSTRACT Acylated anthocyanins from a purple-fleshed sweet potato (PFSP), obtained by organic cultivation in Brazil, were characterized after separation by a high performance liquid chromatography-diode array detector (HPLC-PDA). These anthocyanins were manually collected at the detector output, concentrated and injected into a high resolution mass spectrometer (ESI-QTOF-MS2). Twenty-two acylated anthocyanins were detected. Among them, sixteen had been reported in the literature and six, derived from peonidin were reported for the first time in sweet potato roots in this study. These compounds showed molecular ions with accurate mass/charge ratios (m/z) of 909.2081, 961.3010, 961.2571, 963.3345, 1123.2932 and 1179.3862. Although anthocyanins in PFSP have... |

| ABSTRACT: Vitamin A deficiency is the third most important micronutrient deficiency having a significant impact on public health worldwide. The aim of this study was to develop a carotenoid extraction process with edible vegetable oils, using a central composite design which, concurrently, enriches the oils with provitamin A carotenoids. The stability of carotenoids in the oil and their shelf life was also evaluated. The process also aimed to meet the Recommended Daily Intake for vitamin A (600 μg retinol equivalent for an adult) with the enriched oil. The results showed that 20 % of the vegetable matrix (dried carrot) in vegetable oil and 5 min of extraction time was an optimum combination for both soy oil (64.43 μg retinol equivalent mL−1) and olive oil... |

| In order to generate simple, efficient analytical methods that are also fast, clean, and economical, and are capable of producing reliable results for a large number of samples, a micro scale extraction method for analysis of carotenoids in vegetable matrices was developed. The efficiency of this adapted method was checked by comparing the results obtained from vegetable matrices, based on extraction equivalence, time required and reagents. Six matrices were used: tomato (Solanum lycopersicum L.), carrot (Daucus carota L.), sweet potato with orange pulp (Ipomoea batatas (L.) Lam.), pumpkin (Cucurbita moschata Duch.), watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) and sweet potato (Ipomoea batatas (L.) Lam.) flour. Quantification of the... |

| Buriti do Brejo (Mauritia flexuosa L.) é um típico fruto da Amazônia, Nordeste e Centro-Oeste brasileiro, muito utilizado na culinária para produção de sucos, doces e vinhos. É considerado uma excelente fonte de carotenóides precursores da vitamina A, apresentando maior concentração de β-caroteno. Além dos carotenóides também encontramos ácido ascórbico e açúcares. O ácido ascórbico administrado em quantidades suficientes pode prevenir os sinais clínicos de deficiência conhecida como escorbuto. O emprego da radiação ionizante gama tem mostrado um potencial efeito na redução de perdas pós-colheita, mantendo a qualidade nutricional dos alimentos. O presente trabalho teve como objetivo avaliar os efeitos da radiação gama, nas doses de 0,5 kGy e 1,0 kGy, na... |

| Two analytical methods for the determination and confirmation of ochratoxin A (OTA) in green and roasted coffee samples were compared. Sample extraction and clean-up were based on liquid-liquid phase extraction and immunoaffinity column. The detection of OTA was carried out with the high performance liquid chromatography (HPLC) combined either with fluorescence detection (FLD), or positive electrospray ionization (ESI+) coupled with tandem mass spectrometry (MS-MS). The results obtained with the LC-ESI-MS/MS were specific and more sensitive, with the advantages in terms of unambiguous analyte identification, when compared with the HPLC-FLD. |

| ABSTRACT Edible films are an alternative to synthetic materials used for packaging foods. The aim of this study was to develop and characterize films made from cassava starch, freeze-dried acai and glycerol. The films were characterized for thickness, water vapor permeability, water solubility, anthocyanins, antioxidant capacity and mechanical properties. The results indicated a rich edible film in anthocyanins with considerable antioxidant capacity (150.70 micromol Trolox), which can extend the commercial validity of the packaged food and meets the growing demand for biodegradable packaging that tends to reduce the environmental impact. The addition results in a significant effect on the polymer matrix reducing the water solubility and water activity. The... |

| A validade comercial de sardinhas das espécies Sardinella brasiliensis e Cetengraulis edentulus mantidas sob refrigeração em gelo (0+2°C) foi determinada por parâmetros analíticos físico-químicos, bacteriológicos e sensorial. Nas duas amostras, os teores de Bases Voláteis Totais (BVT) e Trimetilamina (TMA) atingiram o limite máximo recomendado na legislação (30mg N100g-1 para BVT e 4mg N100g-1 para TMA) após 14 e 8 dias de estocagem, respectivamente. O conteúdo de histamina, putrescina e cadaverina se manteve em níveis inferiores a 2.0µg g-1 nas duas amostras durante o período de estocagem. A produção de hipoxantina variou de 0,65 a 2,62µmol g-1 nas amostras de S. brasiliensis e de 1,40 a 2,09µmol g-1 nas amostras de C. edentulus. A contagem inicial de... |

| ABSTRACT: The objective of this research was to evaluate the nutritional composition and bioactive compounds of whole umbu fruit, including pulp, seed and peel, and also of a commercial umbu pulp. Samples of the fractions and of commercial pulp were analyzed for determination of minerals and proximate composition, total phenolic and antioxidant activity. Pulps and peel were also analyzed for vitamin C and carotenoids contents. Commercial pulp presented better nutritional composition than fresh pulp (P<0.05) and the peel presented higher phenolic content and antioxidant activity than seed. Peel also stood out by its vitamin C (79 mg.100 g-1) and total carotenoids (2,751 µg.100 g-1) contents, showing that, as the main barrier of the fruit for its... |
