O trabalho teve como objetivo avaliar o rendimento de biodiesel produzido a partir da transesterificação não catalítica do óleo de tungue bruto e in situ sob condições supercríticas do etanol, bem como verificar a influência das condições operacionais sobre o perfil dos ésteres etílicos de ácidos graxos (FAEE). Para executar as reações de transesterificação com etanol supercrítico foi desenvolvida uma unidade experimental multipropósito com reator batelada (500 ml) e sistema de aquisição e monitoramento da pressão, temperatura e tempo de reação. O planejamento fatorial 23 completo com ponto central foi empregado com o intuito de avaliar a influência das condições operacionais. Quando foi utilizado o óleo bruto, avaliou-se o efeito da razão molar de óleo/álcool (1/18 e 1/42), temperatura (290 oC e 330 oC) e tempo de reação (5 min e 55 min), e quando o óleo in situ (semente) foi a matéria-prima, foram avaliados a razão da massa por volume (1/10 e 1/30), temperatura (270 oC e 310 oC) e granulometria (8-10 mesh e inteira). A caracterização e quantificação dos FAEE foi realizada por cromatografia gasosa acoplada a detector de ionização em chama (GC-FID). Foram determinadas as curvas analíticas para os ésteres etílicos dos ácidos: láurico, mirístico, palmítico, palmitoleico, esteárico, oleico, linoleico, linolênico e araquidônico. As condições operacionais exerceram grande influência sobre o rendimento do biodiesel de tungue. A transesterificação a partir do óleo bruto propiciou rendimentos de até 95,7% na condição de ponto central (1/30, 310 oC e 30 min) e a análise de variância ao nível de 95% indicou que o tempo de reação não exerce influência significativa na faixa investigada. Em relação ao perfil de FAEE, o teste Tukey ao nível de 5% de probabilidade indicou diferenças significativas entre as médias. Ésteres etílicos de ácidos graxos saturados são influenciados positivamente pelo acréscimo da temperatura e tempo de reação, aumentando seus teores, enquanto que, os teores de insaturados decrescem. A transesterificação in situ do óleo de tungue proporcionou atingir rendimentos de até 94,0%. As análises estatísticas indicaram que a granulometria investigada não exerce influência sobre o rendimento e perfil de FAEE. A biomassa residual de tungue, obtida após o processo de transesterificação in situ, possui elevado valor energético, com poder calorífico superior de 8.124 kcal/kg.
Abstract : The objective of this study was to evaluate the yield of biodiesel produced from non-catalytic transesterification of raw crude tung oil and in situ oil, under supercritical conditions of ethanol, as well to determine the influence of the operating conditions on the profile of ethyl esters of fatty acids (FAEE). To perform the transesterification reactions with supercritical ethanol it developed a multipurpose experimental unit with batch reactor (500 ml) and system of the acquisition and monitoring of pressure, temperature and reaction time. A 23 factorial design with central point was applied in order to evaluate the influence of operating conditions. When the crude oil was used as raw material were evaluated the molar ratio of oil/alcohol (1/18 and 1/42), temperature (290 oC and 330 oC) and reaction time (5 min and 55 min). When used in situ oil was evaluated the mass/volume ratio (1/10 and 1/30), temperature (270 ºC to 310 ºC) and particle size (8-10 mesh and whole). The characterization and quantification of esters were performed by gas chromatography coupled with a flame ionization detector employing the method of internal standardization with methyl heptadecanoate. Were determined the analytical curves for the ethyl esters of fatty acids: lauric, myristic, palmitic, palmitoleic, stearic, oleic, linoleic, linolenic and arachidonic. Operational conditions have exerted great influence on the yield of biodiesel of tung. The transesterification from crude oil afforded yields of up to 95.7% in the central point of condition (1/30, 310 ºC and 30 min) and the analysis of variance at 95% indicated that the reaction time had no influence significantly in the investigated range. Regarding the profile of FAEE, the Tukey test at 5% probability indicated significant differences between means. Ethyl esters of saturated acids are positively influenced by increased temperature and reaction time, while the content of the unsaturated decrease. The in situ transesterification of tung oil afforded achieve yields of up to 94.0%. Statistical analysis indicated that the particle size investigated had no influence on yield and FAEE profile. The residual biomass tung originated from the process of the in situ transesterification possesses high energetic value, with superior calorific power of 8,124 kcal/kg.

No Brasil a produção de girassol e o consumo de óleo vêm crescendo significativamente nos últimos anos, em função da demanda crescente do setor agroindustrial e comercial e, pela excelente qualidade do óleo. O uso de prensas para a extração de óleo de girassol pode ser uma alternativa para produtores familiares que cultivam grãos com alto teor de óleo, agregando valor a cultura do girassol. No presente trabalho foram estudadas as sementes de três cultivares de girassol (Catissol, EMBRAPA 122 e uma variedade híbrida) cultivados em sistema orgânico, o óleo obtido a partir de prensagem mecânica e a torta resultante da prensagem. Os seguintes parâmetros foram determinados: composição em ácidos graxos, tocoferóis, composição nutricional e estabilidade oxidativa. O óleo, mantido a temperatura ambiente em vidro âmbar, foi monitorado mensalmente durante os primeiros três meses e, quinzenalmente até completar seis meses de armazenamento. Foram determinados o índice de peróxido, extinção especifica a 232 e 270 nm, índice de acidez e ponto de fumaça segundo normas da AOCS (American Oil Chemist#s Society) A estabilidade oxidativa foi avaliada através da oxidação acelerada em estufa (Schaal Oven Test). De acordo com os resultados obtidos foram observadas diferenças significativas na composição nutricional entre os cultivares. Para os testes de oxidação acelerada a maior estabilidade oxidativa foi observada para o óleo obtido do cultivar Catissol, que apresentou também o maior teor de tocoferóis totais. Após seis meses de estocagem do óleo os valores de índice de peróxido variaram de 0,2 para 7,2 meq/Kg; extinção específica a 232 e 270 nm de 1,8 e 0,3 para 5,0 e 1,8 respectivamente; índice de acidez de 0,6 para 0,8 mg KOH/g e; ponto de fumaça de 180oC para 140oC. Após seis meses de estocagem o óleo manteve-se adequado para o consumo, com índice de peróxido e acidez de acordo com o estabelecido pela legislação brasileira para óleos não refinados (máximo de 15 meq/Kg e 4,0 mg KOH/g respectivamente), não sendo adequado para a utilização em frituras, em função do baixo ponto de fumaça (140oC). The production of sunflower and the consumption of its oil has grown significantly in the last years in Brazil, due to the growing demand of the agro-industrial and commercial sectors and the superior oil quality. The use of screw-press for extracting sunflower oil becomes an alternative for small producers cultivating grains of high oil content, adding value to the culture. In this study, seeds, crude oil and cake of three sunflower varieties (catissol, EMBRAPA 122 and a hybrid variety), cultivated in organic system, were studied. Nutricional, fatty acid and tocopherol composition and oxidative stability were determined. Oil kept at room temperature in amber-colored glass bottles was monitored monthly for the first three months and then fortnightly until six months of storage. The peroxide value, specific extinction (232 and 270 nm) acid value and smoke point were determined according to the AOCS methodology. Oil stability was evaluated through accelerated oxidation (Schaal Oven Test). According to the results obtained, significant differences on nutritional composition among the studied varieties were observed. For accelerated oxidation tests, the highest oxidative stability was observed for oil obtained from Catissol, which presented the highest total tocopherol content. After six months of storage, peroxide value ranged from 0,2 to 7,2 meq/Kg; specific extinction at 232 and 270 nm ranged from 1,8 and 0,3 to 5,0 and 1,8 respectively; acid value ranged from 0,6 to 0,8 mg KOH/g; smoke point ranged from 180oC to 140oC. After six months of storage the oil was still suitable for consumption, with peroxide and acid value in accordance with the Brazilian legislation regarding crude oils (peroxide value of 15 meq/Kg and acid value of 4,0 mg KOH/g), but not suitable for frying due to its low smoke point (140oC).

Resumo: A cera do óleo de farelo de arroz (OFA) é um resíduo da etapa de deceragem no processo de refino de óleos. Tradicionalmente, as ceras naturais, que em excesso geram turbidez no óleo vegetal embalado, são removidas por cristalização e filtração a baixa temperatura. Esse resíduo da etapa de deceragem pode conter de 20 a 80% em massa de óleo, seguido por uma fração principal de ceras, álcoois graxos livres, ácidos graxos livres e hidrocarbonetos. A fração de cera do resíduo é constituída por álcoois graxos e ácidos graxos de cadeia longos esterificados (mais de 18 carbonos). Considerando que o óleo de farelo de arroz tem 4-6% em massa de cera, uma grande quantidade dessa fonte natural de compostos graxos é subaproveitada na indústria de óleos vegetais. De acordo com a revisão bibliográfica, nenhum trabalho na literatura trata da produção de ácidos graxos e de álcoois graxos a partir da hidrólise do resíduo extraído da etapa de deceragem usando vapor supersaturado (elevadas temperaturas e alto vácuo). Nestas condições, a reação de degradação de ceras, ou de desesterificação, ocorre sem a presença de catalisadores em um meio graxo. Diante do exposto, esta dissertação de mestrado teve por objetivo o estudo inédito de aplicação das mesmas condições da desacidificação por via física como rota na produção de ácidos graxos e álcoois graxos a partir do resíduo da etapa de deceragem de óleo de farelo de arroz, sob baixa pressão, a temperaturas elevadas e mediante a injeção de vapor de arraste. Os experimentos foram realizados de acordo com um planejamento fatorial simples (23 + 3 pontos centrais) considerando a temperatura da camisa de aquecimento do vaso do desodorizador (ºC), a vazão de vapor de arraste (mL de água 25 ºC/ min) e o tempo de stripping (min) como variáveis independentes. Os efeitos destas variáveis foram relacionados aos resultados de análises químicas, sendo que, em cada ensaio, foram colhidas amostras para o resíduo e destilado, e analisadas quanto ao teor de ácidos graxos livres, espectros de infravermelho com transformada de Fourier (FTIR), calorimetria exploratória diferencial (DSC) e a técnica EASI-MS (Easy Ambient Sonic- Spray Mass Spectrometry)
Abstract: The rice bran oil wax is a residue of step dewaxing in oil refining process. Traditionally, natural waxes, which generate excessive turbidity in commercial vegetable oil, are removed by crystallization and filtration at low temperatures. This residue of the dewaxing step or winterization may contain from 20 up to 80% by weight of oil, followed by a main fraction of waxes, free fatty alcohols, fatty acids and hydrocarbons. The wax fraction of the residue is composed of esterified fatty alcohols and long-chain fatty acids (more than 18 carbons). Considering that rice bran oil has 4-6% by weight of wax, a large amount of such natural source of fatty compounds is undervalued by the oil industry. According to literature review, no work has reported the production of fatty acids and fatty alcohols from the hydrolysis of the winterization residue using supersaturated steam (high temperatures and high vacuum). Accordingly, the degradation reaction of waxes, or deesterification occurs without the presence of catalysts in an oily medium. Given the above stated, this dissertation aimed to study the unprecedented application of the same conditions as stripping steam deacidification in the production of fatty acids and fatty alcohols from the residue of dewaxing step of rice bran oil, under low pressure, elevated temperatures and with the injection of stripping steam. The experiments were performed according to a simple factorial design (23 + 3 central points), i.e., temperature of the still heating jacket (ºC), the flow of stripping steam (mL water 25 ºC / min) and stripping time (min) as independent variables. The effects of these variables were related to the results of chemical analysis, and in each test, samples were taken for residue and distillate, and analyzed for their content of free fatty acids , spectra of Fourier transform infrared (FTIR), differential scanning calorimetry (DSC) and EASI-MS (Easy-Ambient Sonic Spray Mass Spectrometry)

Full textEmerging molecular imaging techniques in small animals allow a non invasive study of animal models of diseases, providing in vivo information on metabolic pathways. The metabolic process can be visualized and quantified by images, avoiding animal sacrifice which is often mandatory with conventional techniques In this work we show how small animals Positron Emission Tomography (PET) and Computed Tomography (CT) usefully provide metabolic and anatomic information respectively, in a non invasive fashion. Toghether with other conventional approaches, these molecular imaging techniques allowed, in the present work, to collect information on the pathofisiological mechanisms underlying energy metabolism and consequently body weight control in obesity. The first project of the PhD focused on the comprehension of the mechanism by which endocannabinoid system is able to control energy balance at different anatomical sites. The endocannabinoid system (ECS) is a physiological system composed by endogenous lipid molecules regulating energy metabolism acting on the cannabinoid receptor type 1 (CB1). This receptor is expressed in different anatomical sites as central and peripheral nervous system, adipose tissue, liver, skeletal muscle. The ECS is pathologically over-activated during obesity and this overactivation is known to contribute to fat mass and body weight accumulation in obese individuals. The mechanisms and the major anatomical sites underlying this control, are, however, not fully elucidated yet. We focused on the role played by CB1 receptor expressed in some neuronal population. To this aim, the phenotype of conditional knockout for CB1 receptor in some neuronal populations was studied, and compared with the phentype of global CB1 receptor knockout mice (mice having a whole body deletion of the receptor). We found that neuronal CB1 receptor has a deep influence in the ability of ECS to control energy balance and the plasma metabolic profile during obesity. This property of neuronal CB1 receptor is strictly linked with a modulation of the peripheral sympathetic tone which finally influences the metabolic activity of peripheral organs. This loop seems to be particularly effective in modulating brown adipose tissue (BAT) activity, which apparently underlyes most of the changes in whole body energy metabolism observed in the conditional mutant mice for neuronal CB1. These results, which show a strict functional relationship between ECS and BAT thermogenic activity, highlight BAT as a key organ able to control fat mass and body weight gain in obese individuals. The second project of this PhD thesis focused on the relationship between BAT, insulin sensitivity and obesity. BAT is an insulin sensitive organ having a very high uptake of glucose per gram of tissue. The role of insulin on glucose uptake in BAT is still poorly understood, and it is not clear whether BAT insulin function is compromised with obesity. Using a small animal PET/CT imaging approach we analysed in vivo glucose uptake in the BAT of lean and diet-induced obese mice in basal condition and after insulin stimulation. All these findings allowed us to demonstrate that diet induced obesity is associated with an altered (reduced) insulin function in the BAT. Recent experimental evidences indicate that BAT is an important organ in insulin induced glucose clearance in humans; thus, the data obtained in this PhD project, which indicate a compromised insulin function in the BAT of obese individuals, highlight this tissue as a new target to control insulin resistance in obesity.
