Brewers’ spent grain (BSG) is the primary by-product of beer production, and its potential use in food products is largely dependent on its processing, given its moisture content of up to 80%. This study aimed to evaluate the effects of physical separation with ultrasound application on the color, total phenolic content (TPC), antioxidant activity, proximate composition, total dietary fibers, and particle size distribution of BSG powders. Wet BSG (W) was subjected to two processes: one without ultrasound (A) and one with ultrasound (B). Both processes included pressing, convective air-drying, sieving, fraction separation (A1 and B1 as coarse with particles ≥ 2.36 mm; A2 and B2 as fine with particles < 2.36 mm), and milling. The total color difference compared to W increased through both processes, ranging from 1.1 (B1 vs. A1) to 5.7 (B1 vs. A2). There was no significant difference in TPC, but process B powders, particularly B2, showed lower antioxidant activity against ABTS•+, likely due to the release of antioxidant compounds into the liquid fraction during pressing after ultrasound treatment. Nonetheless, process B powders exhibited a higher content of soluble dietary fibers. In conclusion, ultrasound application shows potential for further extraction of soluble fibers. However, process A might be more practical for industrial and craft brewers. Further studies on the use of the resulting BSG powders as food ingredients are recommended.

Abstract Brown propolis from permanent preservation and reforestation areas of southern Brazil have attracted international commercial interest and have a unique composition, although little is known about their botanical origins, which are the plant resins used by bee foragers to produce propolis. Hence, the volatile profiles of organic and non-organic brown propolis and resins of suspected botanical origins—Araucaria angustifolia, Pinus elliott and Pinus taeda—were determined using static headspace gas chromatography coupled to mass spectrometry (SHS-GCMS) and compared. Nighty nine volatiles were tentatively identified, and monoterpenes and sesquiterpenes were the most abundant classes. Principal component analysis (PCA) showed similarity between organic propolis and A. angustifolia volatile profiles (p

- Abstract
Although Brazil nut is a nutrient-dense nut known to be the dietary source with the highest concentration of selenium, there are few studies about the nutritional value of its co-products as well as the processing effects on them. The objective was to assess the nutritional values of Brazil nut water-soluble extract (BNWSE) and water-extracted Brazil nut flour (BNF) produced in a similar way as they are in the Brazilian Amazon basin, as well as to track nutrient losses during water extraction process. Both BNWSE and BNF exceed 100% of the Dietary Reference Intake (DRI) values for selenium; and BNF exceeds 100% of the DRI for copper. BNWSE presents high concentration of copper, while BNF presents 50% of lipids, mainly linoleic and oleic acids, 25% of proteins, and high concentrations of zinc, magnesium, phosphorus and manganese. Hence, water-extracted Brazil nut co-products are outstanding nutrient-dense food sources, and may be helpful alternative foods or food ingredients to tackle mineral deficiencies worldwide. Nevertheless, water extraction process leads to mineral losses, remarkably for selenium, which may add up to 73%, which converses with results reported in literature. Additionally, linoleic acid content tended to be compromised during BNWSE production; thereby process improvements should be considered.

O presente artigo analisou a compatibilidade de três modelos de indicadores, relacionados com o desenvolvimento humano e sustentável, do sistema das Nações Unidas, em relação aos Princípios do BellagioSTAMP. Para isto, foi utilizado o método comparativo para a análise, que permitiu concluir que os BellagioSTAMP ainda não são atendidos pelo conjunto de sistema de indicadores e indicador - síntese analisados. Alguns princípios, como existência de considerações essenciais e ampla participação, constituem-se como os mais problemáticos, indicando a necessidade de melhoria da qualidade no processo de constituição de indicadores. O IDH-M foi o modelo que menos atendeu aos princípios, seguido pelo IDS. A Metodologia GEO Cidades se destacou como o modelo que mais atendeu aos princípios, sendo sua utilização e a inspiração em seu modelo aconselhável, dentre os modelos estudados, para a criação e o uso de indicadores capazes de aferir o caminho rumo ao desenvolvimento sustentável.

Commercially certified organic propolis produced in areas of environmental conservation and reforestation forests of Southern Brazil are generally poor in flavonoids, although one of its variants – Brazilian certified organic propolis 1 (OP1) – has shown strong antioxidant activity. The objective was to identify active compounds from OP1 related to its strong antioxidant activity. OP1 ethanolic extracts were subjected to liquid-liquid fractionation, and the fractions presenting the strongest antioxidant activity were combined and purified into subfractions. Compounds isolated from the most active subfractions had their structure elucidated by Nuclear Magnetic Resonance (NMR). As a result, five lignans and two lignan-precursors were isolated, and four of them are herein reported for the very first time in propolis. Hence, these compounds may be used as chemical markers for product standardization and authentication purposes, since OP1 is only produced by honeybees in native forests and its botanical origins remain unknown.

The polymeric suspension of chitosan (Ch) has been an effective media for the extraction of total phenolic compounds (TPC) from the acerola by-product. It facilitates the subsequent production of nanoparticles loaded with the phenolics (Np-TPC) by ionic gelation. However, neither the effects of Ch concentration on encapsulation efficiency (EE%) of TPC nor which compounds are extracted in its media are known, being it the first objective of this study. The second objective was to analyze the stability of the Np-TPC under accelerated conditions and its release profile at pHs 3.0 and 7.0. The results showed that Ch does not affect the extraction of TPC. However, the EE increased from 35.0 to 48.1 % with the increase of Ch concentration (0.4 to 1.0 %). LC/ESI-QTOF MS analysis showed that phenolic acids and flavonoids are extracted in 0.8 % Ch medium. After encapsulation, microscopy images revealed particle sizes ranging between 110 and 150 nm. Additionally, the presence of phenolics did not change the stability of the particles under accelerated conditions and the actives were fully released into the released medium for 10 h. The Np-TPC suspension appears to be useful for the production of edible antioxidant coatings to preserve fruits/vegetables, with potential application as carrier of other food ingredients.

Vitamin E comprises compounds consisting of a chromanol ring and an isoprenoid side-chain, and is an essential lipid-soluble nutrient with several physiological functions. Vitamin E intake has been reported as inadequate for some populations. Only a fraction of dietary vitamin E is effectively released from the food matrix (bioaccessible fraction), absorbed (enterocyte uptake/epithelial transport) and transported in lipoproteins to reach the target tissues (bioavailable fraction), depending on the food structure, composition, and processing. Therefore, research concerning the fate of vitamin E through the gastrointestinal tract is of paramount importance for developing healthy foods and guiding effective public policies. The combination of simulated in vitro gastrointestinal digestion followed by intestinal epithelial transport and/or enterocyte uptake assays using ex vivo cell models has been successfully used to mimic the physiological conditions and predict the bioaccessibility and epithelial transport of compounds. The objective of this review was to summarize the current knowledge and challenges for predicting the bioaccessibility and uptake/epithelial transport of vitamin E by in vitro and ex vivo assays. Here, we revisited the metabolism of vitamin E and introduced in vitro and ex vivo methods for estimating the bioaccessibility and intestinal absorption of vitamin E. This review compiles data on vitamin E bioaccessibility in vitro and uptake/epithelial transport ex vivo for different food matrices, and discusses the factors that can affect their measurement. Additionally, co-culture approaches using hepatic lineages to assess vitamin E bioavailability are further presented.

Data concerning physiological recovery of whole peanut major phenolics throughout the gastrointestinal tract are scarce. In our study, the bioaccessibility and intestinal permeability of peanuts major phenolics were predicted by simulated digestion followed by Caco-2 cells monolayer model. Phenolics identification and quantification were performed by HPLC-ESI-QTOF-MS and HPLC-PDA, respectively. As results, p-coumaroyl conjugates with tartaric, sinapic and ferulic acids, and p-coumaric acid were the major phenolics found in the non-digested extract and in the digested and transported fractions. The in vitro bioaccessibility and Caco-2 cell transport of p-coumaric acid was 370% and 127%, respectively, while it was much lower for p-coumaroyl derivatives (7-100% and 14-31%, respectively). Nonetheless, the peroxyl scavenging activity remained unaltered, likely, at least partly, due to synergies between some phenolics, which concentration proportions changed throughout the experiment. Hence, there is indication that whole peanut is a source of bioavailable antioxidant phenolics.

Identify the botanical origins of a certain type of propolis may be challenging and time demanding, since it involves bee's behavior observation, plant resins collection and chemical analysis. Thus, this study aimed to determine the plant genetic materials in propolis from southern Brazil using the DNA barcoding to investigate their botanical origins, as well as to compare it with the phytochemical composition determined by ultra-high-performance liquid chromatography coupled with high-resolution mass spectrometry (UHPLC-HRMS) and with the pollinic profile. As principal results, non-native Populus carolinensis Moench (Salicaceae) was almost the only DNA source in some propolis samples, which coincided with the presence of flavonoids typical from poplar exudates. Conversely, other propolis samples had DNA material coming mainly from native plant species, most of them characterized to the species level, although no specific chemical markers from those plants could be identified by UHPLC-HRMS. However, pollen from several plants identified by the DNA barcoding were extracted from some propolis samples. Despite the identification of typical diterpenes, DNA material from Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae), which have been indicated as a major resin source for propolis from preservation areas in southern Brazil, was found in very small abundancies, likely because bees do not drag tissue material containing DNA when collecting resin from this native species. In conclusion, DNA barcoding analysis successfully provided information about the provenance of propolis, although, depending on the plant resin sources, this information is likely to come from pollen.

Propolis comprises a complex resinous product composed of plant's parts or exudates, pollen, bee wax, and enzymes. Brazilian brown propolis from Araucaria sp displays several biological activities. Considering the lack of validated analytical methods for its analysis, we are reporting the development of a validated high-performance liquid chromatography with photodiode array detector method to analyze Araucaria brown propolis. The crude propolis were extracted and chromatographed, furnishing six main diterpenes. The isolated standards were used to draw the analytical curves, allowing the studies of selectivity, precision, accuracy, recovery, robustness, the determination of limits of detection and limits of quantification. The mobile phase consisted of 0.1% acetic acid in water and acetonitrile, using an octadecylsilane column, 1 mL/min flow rate and detection at 200 or 241 nm. Relative standard deviation values obtained for intra-day and inter-day precision were lower than 4% for all diterpenes. From the five parameters for robustness, wavelength detection and flow rate were the critical ones. Limits of detection and quantification ranged from 0.808 to 10.359 μg/mL and from 2.448 to 31.392 μg/mL, respectively. The recoveries were between 105.03 and 108.13%, with relative standard deviation values around 5.0%. The developed method is precise, sensitive, and reliable for analyzing Araucaria brown propolis.

O marketing aplicado à indústria de alimentos tem sido apontado como um dos principais elementos na etiologia da obesidade infantil e no desenvolvimento de doenças crônicas não transmissíveis associadas à dieta. O objetivo do artigo foi, por meio da elaboração de revisão bibliográfica, analisar os estudos sobre a influência da publicidade e propaganda no estado nutricional de crianças e adolescentes e no comportamento alimentar conduzidos no Brasil. Realizaram-se buscas em bases de dados científicas virtuais e foram analisadas publicações selecionadas, com base em critérios pré-estabelecidos. Constatou-se que a maioria dos anúncios de alimentos na mídia televisiva brasileira refere-se a produtos considerados não saudáveis e que a influência do marketing sobre o consumo alimentar de crianças e adolescentes é relevante. O tempo despendido em frente à tela por esses indivíduos é excessivo (≥ 2,5 horas/dia) e, adicionado a hábitos como comer enquanto se assiste televisão e dedicar tempo insuficiente à prática de atividades físicas, está associado ao excesso de peso. No tocante ao conteúdo das propagandas e informações divulgadas em rótulos presentes nas embalagens dos produtos alimentícios, notou-se a necessidade de aprimoramento da atuação reguladora do setor público, tanto no que se refere à fiscalização, quanto à legislação vigente. Além disso, intervenções governamentais de estímulo a escolhas alimentares adequadas e estilos de vida saudáveis são essenciais para a redução da prevalência de sobrepeso e obesidade, especialmente para crianças e adolescentes com status socioeconômico baixo.

O pescado é um alimento que se destaca nutricionalmente quanto à quantidade e qualidade das suas proteínas, à presença de vitaminas e minerais e, principalmente, por ser fonte de ácidos graxos essenciais ômega-3 eicosapentaenoico (EPA) e docosaexaenoico (DHA). O consumo desses lipídios é associado à redução do risco de doenças cardiovasculares e a funções importantes nas fases iniciais do desenvolvimento humano. No Brasil, os autores têm concentrado suas análises sobre consumo de pescado com base em dados obtidos em localidades da região Norte, que apresenta elevada disponibilidade do alimento em relação às demais regiões brasileiras. O objetivo do presente artigo foi analisar a importância nutricional do pescado e o consumo no Brasil, discriminando-o de acordo com as regiões geográficas. Foi possível inferir que: a ingestão regular de pescado traz benefícios à saúde humana e que o risco de contaminação por elemento químico é considerado baixo; o consumo é reduzido, com exceção das regiões Norte e Nordeste, e não houve ampliação no período de 1970 a 2009; há distinção entre as quantidades ingeridas (per capita) e a diversidade de espécies preferidas, de acordo com as regiões.

Brazil nut flour (BNF), as a byproduct from Brazil nut water-soluble extract production, has high contents of protein and linoleic acid. The effect of minor variations in water activity (aw) on lipid oxidation and nonenzymatic browning reactions (NBR) rates in BNF has been studied. For that, the tendency of radical formation detected directly by electron spin resonance spectroscopy, formation of lipid hydroperoxides and browning index were measured in samples with initial aw of 0.101 and 0.196 throughout 18 days of storage at 60 °C. The tendency of radical formation and the formation of lipid hydroperoxides sharply increased and linearly correlated with browning index for BNF with initial aw of 0.196, but not for BNF with initial aw of 0.101. Furthermore, volatile aroma compounds (VACs) including those from the scission of lipid hydroperoxides and those from the breakage of brown polymeric compounds formed during NBR were determined by HS-SPME–GC–MS analysis and the latter were tentatively identified only in BNF with initial aw of 0.196. Hence, there is indication that the lower the initial aw, the greater the storage stability of BNF. Moreover, lipid oxidation products may have contributed to NBR for BNF with initial aw of 0.196.

The objective of this exploratory study was to assess the changes on lipidome and metabolome profiling of Longissimus lumborum bull muscle with different ultimate pH (pHu) and aging periods. The bull muscles classified as normal, intermediate, or high pHu were collected from a Brazilian commercial slaughterhouse, cut into steaks, individually vacuum-packaged, and aged for 3 days (3-d) or 21 days (21-d) at 2 °C. Muscle extracts were analyzed for the profiles of both lipids, by mass spectrometry (via direct flow-injection), and metabolites, by nuclear magnetic resonance, with downstream multivariate data analysis. As major results, pairwise comparisons identified C12:0 and C14:0 acylcarnitines as potential biomarkers of the intermediate pHu-muscle, which are related to lipid catabolism for alternative energy metabolism and indicate less protein breakage postmortem. Interestingly, the concentration of arginine at early postmortem aging (3-d) may influence the previously reported improved tenderness in normal and high pHu-muscles. Moreover, upregulation of fumarate, formate, and acetate with increased pHu muscle at 21-d aging indicate more intense tricarboxylic acid cycle, amino acid degradation, and pyruvate oxidation by reactive oxygen species, respectively. These three compounds (fumarate, formate, and acetate) discriminated statistically the muscle with high pHu at 21-d aging. The normal pHu-muscle showed higher concentrations of glycogenolysis and glycolysis metabolites, including glucose, mannose, and pyruvate. Hence, our results enhance knowledge of postmortem biochemical changes of beef within different pHu groups aged up to 21 days, which is essential to understand the mechanisms underpinning bull meat quality changes. • Lipidome and metabolome to assess beef with distinct ultimate pH and aging time. • Acylcarnitines identified as potential biomarkers of aged intermediate pHu-muscle. • Fumarate, formate and acetate as potential biomarkers of high pHu-muscle at 21-d aging. • Arginine found in higher concentrations in normal and high pHu-muscles at 3-d aging.

Brazil nut is the seed of the Bertholletia excelsa tree, which grows naturally in the rainforests of South America. The production chain is environmentally sustainable as seeds are collected from the hard-shelled indehiscent fruits as they fall on the forest floor, without the need of deforestation. Brazil nut is among the most popular and commercially important tree nuts, and a reduced risk of coronary heart disease among other health benefits have been related to their consumption. A high content of both soluble and bound phenolic antioxidants, especially in the brown skin of the kernel, partly explains this positive health effect together with a high content of oleic acid and linoleic acid. The ω-3/ω-6 is less favorable, but the relatively high content of delta-tocopherol for a tree nut and the highest selenium (Se) level among all foods warrant other health benefits such as antioxidant activity and anticancer effects. Se levels in Brazil nuts vary strongly depending on origin, and recommendations for their safe consumption should be made and added in food labels in order to avoid selenosis.

Background There are more than 30 peanut cultivars registered in Brazil. However, there are no published data about the content of nutrients and antinutrients even in the most commercially important ones. Therefore, our objective was to characterize commercial peanut cultivars harvested in Brazil by determining proximate and fatty acid composition and content of selected minerals and phytates, saponins and condensed tannins. Results Significant variations were found among the cultivars for almost all studied nutrients, except Mg. Granoleico and IAC 505 were identified as high oleic. Results were compared with data from the Brazilian Food Composition Table (TACO) and, for this, percentage differences (D%) were calculated. Appreciable D% were found for proteins, lipids, ash, dietary fiber, almost all fatty acids (except 20:0) and almost all studied minerals (except zinc). Moreover, remarkable variations in content of antinutrients were observed. IAC Red Tatu had the highest content of saponins; IAC OL3 and IAC 886 had the highest amounts of phytates; and IAC 886 had the highest amounts of condensed tannins. Conclusion Results confirm the relevance of differentiating cultivars in the market and in national food composition tables and databases. Furthermore, some of these cultivars may be indicated for new use trends. © 2019 Society of Chemical Industry.

Brazil nuts (Bertholletia excelsa, H.B.K.) are seeds of high nutritional value collected from South American rainforests and its productive chain is one of the most important non-timber economic activities in Brazilian amazon. The main objectives of this research were: 1) characterize the occurrence of chemical changes in Brazil nut kernels (BNK), cold-pressed Brazil nut oil (BNO) and Brazil nut flour obtained by water extraction (BNF); and 2) investigate strategies of control and monitoring these changes during storage. For this, consolidated techniques, such as spectrophotometry and chromatography, and a relatively new analytical technique, the electron spin resonance (ESR) spectroscopy, were employed. As major results, it was found that different combinations of storage temperatures and atmosphere packages have differently affected the tendency of radical formation and off-flavor volatile aroma compounds generation in BNK, and that the combination of refrigeration with vacuum packing was able to keep BNK at their best. It was demonstrated that a spin-trapping ESR spectroscopy method would be suitable to monitor oxidative changes in BNO with known history stored either in clear or in brown glass bottles under retail conditions. For BNF, it was demonstrated that minor variations on water activity (aw) might significantly affect the rates of both lipid oxidation and nonenzymatic browning reactions during storage. There was indication that for BNF with initial aw of 0.196, but not for BNF with initial aw of 0.101, under the studied conditions, secondary products from lipid oxidation might be substrates for nonenzymatic browning products formation. As a conclusion, these results may help to better understand chemical deteriorative processes in BNK and its co-products, according to the storage conditions, and that the use of less sample-demanding, fast and solvent-free analytical method to monitor these changes in BNO is feasible. A castanha do Brasil (Bertholletia excelsa, H.B.K.) é uma semente de boa qualidade nutricional coletada em florestas tropicais da América do Sul, cuja cadeia produtiva é uma das mais importantes atividades econômicas não madeireiras da Amazônia brasileira. Os principais objetivos desta pesquisa foram: 1) caracterizar a ocorrência de alterações químicas em castanhas do Brasil (CB), óleo de castanha do Brasil obtido por prensagem a frio (OCB) e farinha de castanha do Brasil obtida por extração aquosa (FCB); e 2) investigar estratégias para controlar e monitorar essas alterações ao longo do armazenamento. Para isso, técnicas consolidadas como a espectrofotometria e a cromatografia, e uma técnica relativamente recente, a espectroscopia de ressonância de spin eletrônico (RSE), foram empregadas. Dentre os principais resultados obtidos, foi possível constatar o efeito de diferentes combinações de temperaturas e atmosferas de embalagem sobre a tendência de formação de radicais e sobre a geração de compostos voláteis de aroma relacionados a odor indesejável em CB, e que a temperatura de refrigeração combinada com a embalagem a vácuo foi a mais eficiente na preservação da qualidade da CB. Demonstrou-se que o uso de um método de aprisionamento de spins de RSE pode ser eficiente para monitorar alterações químicas em OCB com histórico conhecido embalado em frascos de vidro transparente ou marrons sob condições de armazenamento comercial. Para FCB, foi demonstrado que pequenas variações na atividade de água (aw) podem afetar significativamente as taxas de oxidação lipídica e de reações de escurecimento não enzimático durante armazenamento. Obteve-se indicação de que para FCB com aw inicial de 0,196, mas não para FCB com aw inicial de 0,101, produtos secundários da oxidação lipídica podem ser substratos para a formação de produtos do escurecimento não enzimático. Como conclusão geral, os resultados obtidos podem ajudar a explicar melhor os processos de deterioração química em CB e seus coprodutos, conforme as condições de armazenamento, e que o uso de um método que requer menor quantidade de amostras, é rápido e não usa solventes é viável para o monitoramento da qualidade de OCB.

- Abstract
O presente trabalho aborda a adoção e divulgação de relatórios de sustentabilidade no setor das empresas produtoras de etanol do estado de São Paulo (2013-2015) com o objetivo de analisar a publicação de relatórios de sustentabilidade e a suficiência das informações nele divulgadas. Pretende-se propor um conjunto de Princípios, Critérios e Indicadores (PCI) de desempenho em sustentabilidade, específicos ao contexto da produção de etanol de cana-deaçúcar. O método de pesquisa se baseou em: estudo da adoção de governança corporativa; seleção dos relatórios de sustentabilidade publicados no triênio 2013-2015; definição dos elementos do conjunto (PCI) de avaliação do desempenho em sustentabilidade; avaliação da suficiência de informações publicadas nos relatórios de sustentabilidade; validação de conteúdo dos elementos do Conjunto PCI; e proposição final do Conjunto PCI. Os resultados indicaram que as empresas que declararam adotar governança corporativa representam 20,5% das empresas cadastradas na ANP no estado de São Paulo. As que publicaram relatórios de sustentabilidade representam 11,49% do setor, sendo elas parte das anteriores. Em relação à suficiência de informações, a empresa com maior pontuação obteve 38,26% de suficiência de seu conteúdo, ou seja, bem abaixo dos 50%. As empresas com capital aberto obtiveram posições intermediárias, face às pressões externas por divulgação de informações. A omissão de publicações de informações relevantes foi observada em todas, sendo que 9 das 10 empresas estudadas omitiram informações sobre multas e sanções de aspecto socioambiental. Em relação aos indicadores, os novos propostos obtiveram a melhor pontuação média, superior aos indicadores oriundos do modelo GRI, que já são demandados para a publicação nos relatórios das empresas. A publicação de informações dos indicadores novos propostos superior aos outros indicadores ressaltou a relevância das informações, tanto para as empresas quanto para a academia, pois sua publicação não foi exigida pelo modelo de relatório adotado. De forma geral, pode-se dizer que o setor, como um todo, encontra-se no início de uma jornada em busca do aumento de sua sustentabilidade, sendo que a falta de transparência generalizada denota que há muitos desafios a serem superados, principalmente na divulgação de informações. This thesis approaches the adoption and disclosure of sustainability reports on ethanol industry of São Paulo State on 2013-15, aiming to analyzing the sufficiency of information disclosed on company\'s reports. A set of Principles, Criteria and Indicators (PCI), specific to the production of sugarcane ethanol is proposed to evaluate the performance on sustainability. The steps of research were based on: study of corporate governance adoption on ethanol São Paulo State industry; gathering of sustainability reports published during 2013 to 2015; definition of PCI elements to the evaluation of performance on sustainability; sufficiency assessment of information disclosed on reports; validation of PCI elements; and final proposition of PCI. The analysis has indicated that only 20.5% of companies authorized by National Petroleum, Natural Gas and Biofuel Agency (NPA) on São Paulo State has declared the adoption of corporate governance, whereas 11.49% of companies authorized by NPA has published sustainability reports. The best score among all companies which were studied represented 38.26% on sufficiency assessment, which is below the 50% attendance. Public companies reached intermediate scores, despite external pressures and demands to disclose information, what could lead these companies to higher scores. Some relevant information was omitted in general ways, 9 to 10 companies did not disclose information about socioenvironmental fines. According to the assessment, the new indicators proposed has reached higher scores among the indicator types who compose PCI set, superior than indicators from GRI model, which are already required by on sustainability reports. PCI indicators has reached 62.5% of validation, which represented the definition of 64 indicators to form the basic elements of proposed set. The fact of new indicators proposed have reached higher results appointed to the relevance of these specific information to sugarcane ethanol context. In additional, these results highlighted the need to embody the new indicators proposed to tackled information nonrequired by other sustainability report models. In general ways, the ethanol industry has a long path to increase its sustainability, mostly on disclosure of sustainability.

Background The objectives of the study were to describe caffeine intake by 10 years of age or older Brazilian individuals and to investigate possible associations with demographic and socioeconomic determinants as well as the major dietary sources. Methods The data used are from the personal food consumption module (n = 34,003) of a country-representative household budget survey. Consumed foods and beverages were identified during the application of food diaries. Caffeine contents in food and beverage sources were obtained primarily in national publications. Multivariate regressions were calculated to assess the correlations between population factors and caffeine intake. Results The daily intake per person was estimated as 115.7 mg, ranging from 84.7 mg, for 10–13 years of age children and adolescents, to 139.8 mg, for individuals with no education. The percentage of individuals whom diet reveals daily caffeine intake higher than 400 mg is up to 3.0 %, according to age groups. Males and individuals living in the Northeast or South regions or in the states of Minas Gerais, Rio de Janeiro, and Espírito Santo are likely to ingest higher contents of the substance. The major dietary sources are coffee (63.1 %) and coffee with milk (24.9 %), cola soft drinks (3.6 %) and yerba mate (1.9 %). Conclusions Caffeine intake in Brazil is below the recommended limit reference value for adults, and the percentage of individuals whom diet reveals excessive content of caffeine is low. Thus, excessive caffeine intake may not be a health issue in Brazil and depends on the domicile and gender. The major source in the Brazilian diet is coffee.

Political science - Abstract
A expansão do consumo de alimentos submetidos a elevado grau de processamento em países em desenvolvimento é notória. Em paralelo, observa-se o aumento na prevalência de excesso de peso e de comorbidades associadas. O fenômeno também tem sido observado em famílias consideradas pobres que recebem benefício financeiro de programa federal de transferência condicionada de renda. O objetivo geral foi analisar o consumo alimentar de beneficiários do Programa Bolsa Família (PBF). Foi elaborado um sistema de classificação de alimentos, de acordo com o propósito e grau de processamento. Os dados utilizados são provenientes do módulo de consumo alimentar pessoal da Pesquisa de Orçamentos Familiares (n = 34.003; 7.600 beneficiários), conduzida pelo Instituto Brasileiro de Geografia e Estatística (IBGE) entre os anos de 2008 e 2009. As observações foram classificadas em três faixas etárias: crianças e adolescentes (10 a 18 anos), adultos (19 a 59 anos) e idosos (60 ou mais anos). Os integrantes da amostra também foram discriminados de acordo com o local do domicílio: regiões Norte, Sul, Nordeste, Centro-Oeste, estado de São Paulo e grupamento dos estados de Minas Gerais, Rio de Janeiro e Espírito Santo. Para estimar o conteúdo de carotenoides presente na dieta um banco de dados foi construído e a composição dessas substâncias nos alimentos foi obtida, prioritariamente, em fonte de dados nacional. Foram levadas em conta as distintas formas de preparo. A ingestão de energia, macronutrientes, fibra alimentar, vitaminas e minerais também foi analisada, com base nas composições dos alimentos divulgadas pelo IBGE. O IMC foi calculado e regressões múltiplas ajustadas aos dados, controlando fatores socioeconômicos e demográficos. Notou-se, destacadamente, que a energia fornecida pelos alimentos ultraprocessados torna-se menor para faixas etárias de maior idade. As pessoas beneficiárias do programa apresentaram tendência para obtenção de menor proporção de energia proveniente desses produtos. A ingestão de fibra alimentar foi, em geral, reduzida (exceto para beneficiários do sexo masculino), assim como de ácidos graxos poli-insaturados, e os ácidos graxos trans foram consumidos em excesso. Verificou-se conteúdo insuficiente (valores médios) de vitaminas E, A, D, folato, B1 (em idosas) e B6 (em idosos), cálcio, potássio, magnésio e fósforo (em meninos e meninas). O sódio foi consumido em excesso. As principais fontes dietéticas da maioria dos minerais foram alimentos minimamente processados e in natura, com exceção do sódio e do manganês. Alimentos processados e preparações culinárias (sem alimentos ultraprocessados na receita) foram importantes fontes de vitaminas C, D e do complexo B, mas também de colesterol, lipídeos e ácidos graxos saturados. A elevada quantidade de ácidos graxos trans contida em alimentos ultraprocessados foi notada. O conteúdo estimado de carotenoides na dieta foi baixo e não integrou intervalos preconizados como seguros. Destacaram-se como fontes dessas substâncias, além das frutas, legumes e verduras, o macarrão preparado com molho de tomate (para licopeno) e as sopas (para ?-caroteno e pró-vitamínicos A). Não foi captado efeito estatisticamente positivo, no IMC, da participação das categorias de alimentos. The population\'s growing demand for high processed foods in developed countries is well known. At the same time, it is noted an increase of the prevalence of excess body weight and associated comorbidities. The fact has have also been observed among poor families that receive financial support from federal conditional cash transfer programs. The general aim of this thesis was to analyze food consumption of \"Bolsa Família\" Program (BFP) beneficiaries. A food classification system was developed, according to the purpose and processing level. The data used is from the individual food consumption module of a household expenditure survey (n = 34,003; 7,600 beneficiaries) carried out by Brazilian Institute of Geography and Statistics (BIGS) between 2008 and 2009. Observations were classified in three age strata: children and adolescents (10 to 18 years old), adults (19 to 59 years old) and elderly (60 years old or older). They were also identified according to the geographic regions or states where they live in: North, South, Northeast, Center-West, São Paulo state, and the group of Minas Gerais, Rio de Janeiro and Espírito Santo states. To estimate carotenoid intake in the diet, a database was built and food composition of these bioactive compounds were obtained, with priority, in a national database, and the distinct modes of preparation were considered. The ingestion of energy, macronutrients, vitamins, minerals and dietary fiber was analyzed as well, but according to food composition data from BIGS. The BMI was calculated and multiple regressions were fitted to data, controlling socioeconomic and geographic variables. Amidst the results, it was noted that the higher is the share of ultra-processed foods, expressed as energy intake, the lower is the age strata. BFP beneficiaries tend to obtain lower proportions of energy intake by these foods. In general, the ingestion of dietary fiber (except for men) and polyunsaturated fatty acids was considered low and the consumption of trans fatty acids was high. The amounts (average values) of vitamins E, A, D, folate, B1 (for elderly women) e B6 (for elderly men), calcium, potassium, magnesium and phosphorus (for children and adolescents) were evaluated as low. On the other hand, the sodium intake was expressively high. The main dietary sources of the majority of minerals were minimally processed or in natura foods, except for sodium and manganese. Processed foods and culinary preparations (without ultra-processed foods in their recipes) were important sources of vitamins C, D and B-vitamins, but of cholesterol, lipids and saturated fatty acids as well. The proportion of trans fatty acids obtained in ultra-processed foods was notable. Carotenoid intake in the diet did not fit into Prudent individual daily range intake, and the main sources of these phytochemicals were, beside fruits and vegetables, pasta prepared with tomato sauce (for lycopene) and soups (for ?-carotene and provitamin A carotenoids). No statistically significant effect from the share of energy obtained by foods, categorized into groups, was observed on BMI.

The intake of carotenoids is associated with antioxidant properties and some of these substances have activity of pro-vitamin A. This study aimed to estimate the intake of carotenoids (average values) by the Brazilian population focusing on beneficiaries of the 'Bolsa Família' Program and identify the dietary sources, according to the purpose and degree of processing and the inclusion of food additives. The database used is the personal food consumption module of the Household Budget Survey of 2008-2009, conducted by the Brazilian Institute of Geography and Statistics. The content of carotenoids in foods was obtained primarily from a National data source. Food products were classified into three categories: 1) fresh and minimally processed foods; 2) processed foods (containing food additives, except for flavoring and coloring agents); and 3) highly processed foods (containing flavoring and coloring agents). Insufficient intakes were identified for the conditional cash transfer program beneficiaries (3,547.1 µg). Fresh and minimally processed foods supplied between 48.6% (for girls) and 65.7% (for male adults) of pro-vitamin carotenoids. Processed foods were sources of between 55.5% and 57.0% of lutein + zeaxanthin for elderly and between 58.0% and 67.8% of lycopene for adults. Highly processed foods contributed to less than 5.0% of total carotenoids.

[Display omitted] • Antioxidant activity of propolis remained after digestion and epithelial transport. • Propolis attenuates nuclear factor kappa B activation after epithelial transport. • Propolis reduces the release of cytokines after epithelial transport. • Some lignans and phenolic acids cross Caco-2 cell monolayers. • Acute toxicity was very low for propolis extract and small intestinal fraction. The objective was to assess the effect of gastrointestinal digestion/Caco-2 cell transport on biological activities and toxicity of the ethanolic extract of organic propolis from southern Brazil (EEOP1). As principal results, the EEOP1 deactivated the ROO•, HOCl and O 2 •- reactive oxygen species, attenuated NF-κB transcription factor activation, and decreased the release of TNF-α and IL-6 in macrophages after Caco-2 cell transport, while CXCL2/MIP-2 release was reduced after gastrointestinal digestion. Furthermore, the phytochemical profile monitored by HPLC-ESI-QTOF-MS changed, especially for lignans, lignan-precursors and phenolic acids. Conversely, the antimicrobial activity was observed only in the non-digested EEOP1. The EEOP1 lethal dose to kill 50 % of the Galleria mellonella larvae was 1.1 g/kg, and its digested fraction had no toxic effect. Hence, there is indication that some phytochemicals present in the EEOP1 are resistant to the gastrointestinal tract and maintain their biological activities, as expected for a functional food ingredient.
