Orientador : Maria Cecilia de Figueiredo Toledo Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia de Alimentos e Agrícola Resumo: Fosfato-monoésteres de amido de milho com D.S. de 0,01 a 0,15 foram preparados variando-se as temperaturas e tempos de pirólise e as concentrações de fosfato na mistura de reação. Os produtos obtidos foram analisados quanto a viscosidade, grau de substituição (D.S.), cor, solubilidade e absorção de água. Os efeitos do cloreto de sódio, da sacarose e do pH na viscosidade dos FMA também foram investigados. Foi observado que o incremento da concentração de tampão fosfato de 2,0 M para 4,5 M não aumentou a velocidade de reação de fosfatação. O máximo valor de D.S. foi atingido em 5,3 ou 1 h de pirólise a 155, 170 ou 185°C, respectivamente. Tempos superiores aos de obtenção do máximo D.S. em cada temperatura favoreceram, principalmente, a dextrinisacão e a formação de ligações cruzadas. Não foi encontrada uma relação linear entre D.S. e viscosidade das suspensões de FMA. A viscosidade defendeu das condições de reação, as quais observou-se, devem ser escolhidas levando-se em conta os efeitos das reações de fosfatacão, dextrinização e formação de ligações cruzadas. As características de viscosidade dos FMA foram reduzidas levemente em meio alcalino, mais acentuadamente em meio ácido e aumentadas na presença de ate 55% de sacarose (P/V). Na presença de até 3% de cloreto de sódio (P/V), suspensões a 3% de FMA não apresentaram viscosidade Abstract: Phosphate monoester of corn starch (SPM) with degrees of substitution (D.S.) from 0,01 to 0,15 were prepared using different phosphate concentrations in the reaction mixture, and different temperatures and time of heat treatment. The starch phosphates were analyzed with respect to their viscosity, color, water solubility and water absorption. The effects of sodium chloride, sucrose and pH on the viscosity of the SPM solutions were also investigated. Increasing phosphate buffer concentration from 2.0 to 4,5 M had no effect on phosphorylation rate. Maximum D.S. value was reached in 5, 3 or 1 hour when heat treatment was at 155, 170 or 185°C, respectively. In longer heat treatments, the reactions of dextrinization and crosslink formation were increased. No linear relation was found between D.S. and viscosity of SPM solutions. The viscosity was affected by reaction conditions which should be chosen regarding the effect of phosphorilation, dextrinization and crosslink formation. The SPM solution viscosity decreased through the addition of chloridic acid and sodium hidroxide, and was increased by the addition of sucrose up to 55% (w/v). A 3% SPM solution showed no viscosity with the increase of sodium chloride from 0.5 to 3.0% (w/v) Mestrado Mestre em Tecnologia de Alimentos

BIOFORTIFICATION ,MICRONUTRIENTS ,CORN ,CAROTENOIDS ,ANTIOXIDANTS ,VITAMIN A - Abstract
Maize, in addition to being the main staple food in many countries, is used in the production of hundreds of products. It is rich in compounds with potential benefits to health, such as carotenoids, phenolic compounds, vitamin E, and minerals that act as cofactors for antioxidant enzymes. Many of these compounds have been neglected thus far in the scientific literature. Nevertheless, deficiencies in the precursors of vitamin A and some minerals, such as iron and zinc, in maize, in association with the great genetic variability in its cultivars and our genomic, transcriptomic, and metabolomic knowledge of this species make targeted biofortification strategies for maize promising. This review discusses the potential of the main microconstituents found in maize with a focus on studies aimed at biofortification. [ABSTRACT FROM AUTHOR]

As demais formas devem sofrer ação da enzima β-glicosidase intestinal antes de serem absorvidas pelo organismo, ou que condições de processamento, como encharcamento em grãos de soja sejam realizadas a fim de ativar a enzima β-glicosidase, presente nos grãos, e promover a conversão das isoflavonas conjugadas no próprio grão, aumentando a biodisponibilidade das isoflavonas. Objetivou-se verificar se o uso de tratamentos hidrotérmicos realizados em grãos de soja promoveria aumentos no teor de isoflavonas agliconadas, devido à ativação da enzima β-glicosidase do grão, e se haveria permanência destes compostos em isolado proteico de soja. Os grãos de soja foram tratados hidrotermicamente através de seu encharcamento em água na proporção de 1:5 (p/v, soja:água), em duas temperaturas (40 e 60°C) durante 4, 8, 12 e 16 horas. Os grãos após secos (13%), moídos e desengordurados, originando a farinha desengordurada (FD), a qual foi destinada à produção do isolado proteico de soja (IPS), originando o isolado e duas frações do processo: o resíduo insolúvel (RS) e o sobrenadante (SB). A FD, o IPS, o RS e o SB foram avaliados quanto ao teor de isoflavonas agliconadas e composição química a fim de verificar a permanencia e a manutenção das isoflavonas no IPS frente aos tratamentos hidrotérmicos. Os IPSs oriundos dos grãos tratados hidrotermicamente foram também avaliados quanto suas características funcionais e nutriconais através das análises de eletroforese, DSC, fenóis totais, atividade antioxidante, digestibilidade proteica, solubilidade, capacidade de absorção de água, capacidade de formação e estabilidade da espuma, colorimetria, análise de perfil de textura e microscopia eletrônica de varredura. Concluiu-se que tratamentos hidrotérmicos realizados a 40°C promovem aumentos no teor de agliconas na farinha desengordurada (FD) e no IPS, aumentos no rendimento de extração, no teor de fenóis totais, na digestibilidade, na capacidade de formação e estabilidade da espuma. Os tratamentos a 60°C, apesar de apresentarem menores rendimentos de extração de IPSs, promoveram seletividade de proteínas com maior capacidade de interação com as isoflavonas, produzindo IPSs com maior concentração de agliconas por grama de produto. Soybeans may contain up to twelve types of isoflavones, of which only deconjugated s forms, daidzein, glycitein and genistein, are absorbed directly into the gastrointestinal tract. The other isoflavone forms must suffer of the enzyme β-glucosidase hydrolisys i the gut before being absorbed by the body, or processing conditions, such as soaking in soy beans are undertaken in order to activate the β-glucosidase enzyme, present in grains, and promote conversion of conjugated isoflavones in the grain, increasing the bioavailability of isoflavones. This study assessed the use of hydrothermal treatments performed in soybeans to promote increases the isoflavone aglycone content due to the activation of the enzyme β-glucosidase of the grain, and investigates these compounds in soy protein isolate. Soybeans were treated hydrothermically through soaking in water at a ratio of 1:5 (w/v, soy:water), at two temperatures (40 and 60°C) for 4, 8, 12 and 16 hours.The beans were dried to 13% moisture, milled and defatted, the resulting defatted flour (FD), was destinatedd to produce the soy protein isolate (IPS), the process generated two fractions: the insoluble residue (RS) and supernatant (SB). The FD, IPS, RS and SB were evaluated for isoflavone aglycone and chemical composition in order to check the maintenance of isoflavones in the IPS. The IPSs from grain treated hydrothermically were also evaluated for functional and nutricona characteristics and l through electrophoresis analysis, DSC, total phenolics, antioxidant activity, protein digestibility, solubility, water absorption capacity, foaming capacity and foam stability, colorimetry , texture profile analysis and scanning electron microscopy. It was concluded that hydrothermal treatments performed at 40°C promotes an increase in content of aglycones in the defatted flour (FD). In IPS, hydrothermal treatments increases its yield from extraction, total phenol content, digestibility, in foaming capacity and foam stability. The treatments at 60°C, although having lower extraction yields of IPSs, promoted selective isolation of proteins with greater ability to interact with isoflavones, producing IPSs with higher concentrations of aglycones per grams of product.

Assim, a busca por fertilizantes foliares complementares, capazes de biofortificar culturas e lidar com a deficiência de micronutrientes em plantas, tem sido objeto de vários estudos. Neste contexto, a água extraída do folhelho pirobetuminoso (água de xisto), durante o processo de pirólise para obtenção de óleo combustível e outros produtos, representa uma alternativa segura do ponto de vista ambiental. Neste estudo, a água de xisto foi caracterizada físico-químicamente e avaliou-se a segurança e potencial de sua utilização na agricultura, com ou sem enriquecimento com micronutrientes. Os resultados mostraram uma grande variedade de compostos orgânicos, nutrientes minerais e elementos-traço neste subproduto, representando uma matriz complexa que poderia ser de interesse para a nutrição e a indução do metabolismo primário e secundário das plantas. A aplicação foliar de diferentes doses de água de xisto em alface mostrou ausência de contaminantes tóxicos, indicando a sua segurança para uso na produção de alimentos. Além disso, o aumento na produtividade e em determinados nutrientes em alface, assim como a melhoria do crescimento de plantas de milho e o incremento na produtividade e qualidade de grãos, incluindo metabólitos primários e secundários, também foram observados devido à aplicação foliar de água de xisto. O enriquecimento com micronutrientes também mostrou incremento na produtividade, teor de aminoácidos, bem como no acúmulo de alguns minerais em grãos de milho. No entanto, a suplementação com micronutrientes não aumentou o teor de carotenóides, sugerindo que a água de xisto poderia ser utilizada na agricultura, sem necessidade de enriquecimento, o que representa uma alternativa adequada para fornecer nutrientes e biofortificar culturas. Historically, the aim of agronomic efforts has been focused on yield, using fertilizers that, due to the production processes, have become increasingly free of trace elements and micronutrients, limiting the demand for plants, causing soil depletion, and consequently, limiting the quality of crops. Thus, the search for foliar supplementary fertilizers, able to biofortify crops and to deal with plant micronutrient deficiency, has been the subject of several studies. In this context, the water extracted from shale rock (shale water) throughout the pyrolysis process to obtain fuel oil and other products represent an environment safety alternative. In this study, shale water was characterized physical-chemically and evaluated the security and potential of its use in agriculture delivered with or without micronutrient enrichment. The results showed a great variety of organic compounds, mineral nutrients and trace elements in this by-product, which represent a complex matrix that could be of interest for plant nutrition and induction of primary ans secondary metabolisms. The foliar application of different doses of shale water in lettuce showed an absence of toxic contaminants, indicating its security to use in food production. Furthermore, the increase on yield and in certain nutrients in lettuce as well as the improvement of maize plants growth and grains yield and quality, including primary and secondary metabolites, were also observed by the foliar application of shale water. The enrichment with micronutrients also shows improvements on yield, amino acids content as well as of some minerals accumulation in maize grains. However, micronutrient supplementation did not increase carotenoids content, suggesting that shale water could be used in agriculture without de necessity of enrichment, representing an appropriate alternative to provide nutrients and biofortify crops.

- Abstract
Starch is an important energy source and can represent more than 60% of the calories of the human diet. The starch fraction resistant to enzymatic digestion is called resistant starch. When rice is parboiled, the starch retrogrades with the formation of type 3-resistant starch (retrograded), which presents beneficial effects on the health, since it acts as a prebiotic. In the present study three types of rice were selected, with high, medium and low amylose contents, with the objective of evaluating the effects of conventional and parboiled rice on glycemia in Wistar rats. The samples with high and medium amylose contents were soaked for 6 h at 65 degrees C, and the low amylose sample for 7 h at 70 degrees C. The samples were subsequently autoclaved for 10 minutes at 0.7kgf x cm(-2). Six male Wistar rats were used for each treatment. Seven experimental diets were elaborated, formulated according to AIN-93M, the control diet and diets substituting the carbohydrate source with conventional or parboiled rice. Resistant starch was determined in the diets and glycemia monitored using glucose paper strips, the sample being blood obtained from the distal part of the rat's tail. For the glycemic curve, glycemia was measured in the fasting state and during 90 minutes post-prandial. The results indicated there were no significant differences between the diets formulated with high, medium and low amylose, parboiled or conventionally prepared, with respect to fasting or post-prandial glycemia in Wistar rats.
