Microcapsules of ciriguela peel extracts obtained by ultrasound-assisted extraction were prepared spray drying, whose results compared with those freeze-drying as a control. The effects spray-drying air temperature, feed flow rate and ratio encapsulating agents (maltodextrin arabic gum) studied. Encapsulation efficiency, moisture content, total phenolic compounds (TPC), water activity, hygroscopicity, solubility, colorimetric parameters, profile HPLC/DAD, simulated gastrointestinal digestion...
Abstract One of the most important classes nutritional biomolecules is oleaginous compounds group, which specially includes oil-lipids, carotenoids and fatty acids. These biocompounds present a wide range industrial applications because their ability to act as an energy source, antioxidants metabolic agents for human body. Therefore, food industry, mainly focusing on supplementation, always searching new sources them. In this context, study evaluated total lipids, acids simultaneous...
The spray drying process of a mixed juice acerola and seriguela was optimized using 2 4 full factorial design with 16 points 3 central points. independent variables were different levels inlet temperature (110°, 140° 170 °C), feed flow (0.36, 0.60 0.84 L/h), amount maltodextrin (14-26%) dextrose equivalent (DE) (5, 10 15 DE). responses water activity (Aw), moisture content (MC), hygroscopicity (Hyg), powder recovery (PR) retention ascorbic acid (RAA). After optimization, an acceptance test...
On the world scene, energy requirements are mainly based on fossil fuels, however, these compounds reserves finite and their exploitation has caused serious environmental problems. As a consequence, demand for alternative renewable sources been intensified in substitution rising raw materials. The biomass is emerging as one of few that have potential to meet challenges sustainability, currently largest resource world, only carbon-rich material available planet, apart from fossils. Form,...
CHARACTERIZATION OF CASHEW (Anacardium occidentale L.) WINE.The production of cashew apple wine has the purpose minimizing wastage in Brazilian production.Knowing that fermentation produces a good wine, study alcoholic kinetics and physicochemical characterization product were made.The was produced an stirred batch reactor.The results physico-chemical analysis volatiles, residual sugars, total acidity pH showed their concentrations within standard limits established by legislation for fruit wines.
The microbial protein bioconversion of cactus pear by yeast in solid medium was studied. Three cultivation variables used were: inoculum's concentrations (5, 10 and 15 %), substrate layer thickness (2, 4 6 cm) temperature (30, 34 38 ºC). rate dry matter production total were determined. Results obtained variance analysis, gross energy vitro digestibility. maximum amount achieved for the conditions studied present work higher than 26 %, which compatible or greater those conventional...
HYDROCARBONS IN AQUEOUS EFFLUENTS.Removal of hydrocarbons from aqueous effluents using biosorbents was investigated.The effluent simulated by a dispersion gasoline (simple hydrocarbons) in water.Corn-cob, wood powder, coconut mesocarp and sugar-cane bagasse were used as adsorbents their performance verified means batch experiments performed an agitated vessel.The influence input variables such hydrocarbon concentration, mass biomass agitation level on the adsorbents' capacity studied...
EQUILIBRIUM AND KINETIC STUDY OF Pb 2+ BIOSORPTION BY Saccharomyces cerevisiae.The biosorption, based on the use of biomass for removal ions is distinguished as an innovative and promising technology when compared with traditional methods.In this context, aim present work to cerevisiae biosorbent retention metal ions.Factorial design was used evaluation process.The observed equilibrium data were well described by Langmuir Freundlich adsorption isotherms.The maximum capacity 1486.88 mg/g.The...
FERMENTATION. In the present work, influence of amount nitrogen and phosphorus degrees Brix on yield productivity alcoholic fermentation has been evaluated.The methodology used was factorial design response surface analysis.Within range studied only for a statistically significant effect observed.The broth sugar cane CB 453 variety already possessed enough fermentation.The mathematical empirical model validated not yield.The concentration alcohol produced in to cause cellular growth inhibition.
Para a abordagem da Logoterapia e Análise Existencial de Viktor E. Frankl afirma que é inerente ao ser humano o fenômeno autotranscendência, visibiliza centralidade do sair Eu para Tu (acessibilidade mundo dos outros, tarefa, Suprassentido-Deus), na liberdade responsabilidade, com respostas das demandas existência. O em busca um motivo feliz, vivendo suas realizações, encontra-a como consequência desta atitude. Buscar encontrar sentido vida pode se manifestar por três maneiras: valores...
POLYGALACTURONASE.The aim of this work was to verify the effects initial medium moisture content (U), addition ammonium sulphate (N) and potassium phosphate (P) in production polygalacturonase through solid-state fermentation, using cashew apple husk as substrate Aspergillus niger CCT0916 transformation agent.We also studied best extraction conditions produced enzyme.The condition with U 40%, 1% N 0% P being reached an activity poligalacturonase 10.1 U/g.The is agitation system a time 100...
A produção de proteínas microbianas sobre a casca maracujá visando à suplemento protéico para animais é uma alternativa encontrada o grande desperdício desse resíduo agroindustrial. Através das isotermas dessorção da do maracujá, foi verificado que as condições umidade inicial crescimento microrganismos neste por meio fermentação semi-sólida deverá ser acima 55% (base úmida) e faixa ideal armazenamento em torno 5,3% úmida).
A yogurt-like fermented dairy beverage was elaborated from a mixture containing 70% (v/v) caprine milk and 30% water-soluble soy extract (WSSE), supplemented with inulin (4 g∙100 mL-1). Physicochemical, sensorial, microbiological analyses were carried out to characterize the product evaluate its stability during 28 days of refrigerated storage (5 °C). To compare results, yogurt made whole milk, without supplementation, as control. The use WSSE showed favorable physicochemical physical...
A preocupação com o meio ambiente vem motivando diversas pesquisas sobre uso de materiais pozolânicos em substituição parcial ao cimento concretos e argamassas, entretanto poucos são os dados tal destinados à produção elementos prémoldados, concreto este que geralmente é denominado seco ou sem abatimento, devido baixa umidade requerida no processo moldagem prensagem. Este trabalho consistiu um estudo preliminar metacaulim seco, sendo analisados cinco traços teores tempos cura, objetivando...
CELLULOSE HYDROLYSIS BY MESOESTRUTURATED NiO-MCM-41 AND MoO 3 -MCM-41 CATALYSTS.This study was carried out to synthesize, characterize and evaluate the application of mesoestruturated catalysts MCM-41, 5%MoO 5%NiO-MCM-41 in hydrolysis microcrystalline cellulose.XRD results indicate that phase mesoporous MCM-41 obtained introduction metal oxides did not affect this phase.About heterogeneous reaction, it observed increase temperature a higher concentration glucose catalyst provides highest...
O presente artigo tem o objetivo de apontar e discutir a respeito da representação significação social atribuída à última fase do desenvolvimento humano, saber, velhice, revisar seus conceitos partir pensamento Viktor Frankl sob viés teórico Logoterapia Análise Existencial, pontuando problematizando ética que rege sociedade contemporânea, tendo como base vontade sentido é ação motivacional existência. Foi utilizado, neste trabalho, fundamentos teóricos análise existencial Frankl, por...
