Obtenção de cerveja usando banana como adjunto e aromatizante / Beer obtaining using banana as an adjunct and a flavouring agentCarvalho, Giovani Brandão Mafra de 20 July 2009 (has links)
Nos últimos anos, duas tendências tem se destacado no universo cervejeiro: a obtenção de cervejas a partir de mostos concentrados e a elaboração de cervejas utilizando adjuntos especiais, os quais podem aromatizar ou não as mesmas. Visando um aumento da produtividade juntamente com uma menor necessidade de investimentos na capacidade produtiva, algumas cervejarias vêm optando pelo aumento do extrato inicial de fermentação para valores superiores aos tradicionais (10-15 0P). A elaboração de cervejas utilizando adjuntos especiais vem se tornando uma solução de barateamento na obtenção de cerveja devido à substituição de parte do malte, acrescentando ainda, atributos sensoriais característicos nos produtos obtidos. A banana constitui-se em matéria-prima bastante favorável à fermentação alcoólica por ser rica em carboidratos, minerais e apresentar baixa acidez. O principal objetivo desta pesquisa foi utilizar a banana como um adjunto do malte e como um aromatizante natural e sutil das cervejas obtidas. A quantificação dos carboidratos presentes na banana prata em diferentes graus de maturação revelou que a condição \"muito-madura\", apresentou o mais alto teor de carboidratos totais solúveis (15,65 %) e o mais baixo teor de amido (0,48 %). Após a etapa quantificação dos carboidratos fez-se um estudo da extração aquosa a quente dos sólidos solúveis da banana com a metodologia de superfície de resposta a partir de um planejamento fatorial 22 onde se obteve um modelo matemático empírico quadrático (Y = 5.58 + 1.25 X1 - 0.26 X2 - 0.37 X22). Os valores que otimizaram esta extração (Y) foram 38,5 g de purê de banana (X1) e tempo de extração de 39,7 minutos. Utilizando um planejamento fatorial 22 fez-se um estudo da fermentação do mosto com adjunto de banana, na planta piloto da microcervejaria da EEL - USP em diferentes concentrações e temperaturas. Observou-se que a 12 0P e a 15 0C obteve-se uma Qp de 0,58 g/L.h em 72 h de fermentação e apenas 6,07 % do açúcar metabolizado pela levedura cervejeira foi desviado para a geração de produtos secundários, garantindo um Yp/s real de 0,48 g/g. Dentro destas condições de estudo investigou-se o comportamento cinético da levedura cervejeira Saccharomyces cerevisiae 308 de baixa fermentação (tipo lager) nestes mostos com banana, de densidade tradicional. Pôde-se observar que o máximo valor de ?x (0,114 h-1) foi alcançado com a fermentação a 12 0P e 15 0C. O valores máximos de ?s e ?p (1,128 e 0,585 g/g.h, respectivamente) foram conseguidos com a fermentação a 15 0P e 15 0C. Em seguida, fez-se um estudo com o propósito de aumentar a produtividade volumétrica de etanol em mostos com banana de alta densidade. Para isto, realizou-se fermentações com a adição de diferentes nutrientes, em mini-bioreatores cilindrocônicos de 0,9 L da Uminho - Portugal. Verificou-se que apenas a adição de MgSO4 foi significativa estatisticamente para o aumento da Qp. Observou-se também que o melhor valor de Qp (0,68 g.L/h) foi alcançado em 64 h de fermentação após suplementação com 420 mg/L de MgSO4. Em seguida, fez-se a caracterização físicoquímica da cerveja obtida com a reprodução do experimento otimizado em mini-bioreator cilindrocônico de 0,9 L da Uminho - Portugal no fermentador de 180 L da EEL - USP, verificando-se que a cerveja com banana de 4,8 % v/v apresentou uma elevada concentração de potássio (600,68 mg/L) e de acetato de isoamila (1,20 mg/L). Das cervejas otimizadas elaboradas na planta piloto da USP, fez-se uma avaliação sensorial comparando-as com cervejas do mercado brasileiro. Observou-se que em relação aos testes de preferência, as cervejas com banana foram estatisticamente preferidas em relação às amostras do mercado. Já os testes de aceitação demonstraram que não houve diferença significativa (p >= 0,05) quanto ao grau de aceitação entre os produtos correspondentes às amostras experimentais otimizadas e as amostras do mercado. Ou seja, as amostras de cerveja com banana foram tão aceitas pelo consumidor quanto às amostras de cerveja do mercado. Por fim foi realizado um estudo econômico preliminar, dentro de uma estimativa de produção de 875 L/mês de cerveja com banana em microcervejaria. Verificou-se que o custo inicial do processo foi 204,76 % superior a de uma cerveja comercial. Todavia, o custo direto variável de produção desta cerveja foi de R$ 0,94/L contra R$ 1,10/L de uma cerveja puro malte produzida nas mesmas condições de processo. / In the past years, two tendencies have been revealed in the universe of brewing: beer production using concentrated wort and its elaboration using special adjunct, which might supply or not a special flavour to the beer. Aiming to increase the process productivity along with decreasing the necessity of further production investments, some breweries have adapted to increase the initial fermentation extract concentration to values superior to the traditional ones (10-15 oP). The elaboration of beer using special adjunct is considered a solution to turn cheap beer production by not only by substituting part of the malt but also in adding characteristic sensorial attributes in the obtained products. Banana is constituted of raw materials suitable for alcoholic fermentation for being rich in carbohydrates and minerals and present law acidity. The principal objective of this research is to utilize the banana as an adjunct for malt and also as a natural and a tenuous flavouring agent for the obtained beer. The quantification of the carbohydrates present in the banana prata in different maturation grade, has revealed that the condition of \"very mature\" represented the highest content in total soluble carbohydrates (15.65%) and the lowest content in starch (0.48%). After the quantification stage of the carbohydrates, a study was done on the hot aqueous extraction of the soluble solids found in the banana using the response-surface method obtained by a complete 22 factorial design. The obtained mathematical empirical quadratic model was (Y = 5.58 + 1.25 X1 - 0.26 X2 - 0.37 X22). The values of the optimized extraction (Y) was 38.5 g of banana pulp (X1) and an extraction time of 39.7 minutes. It was done a study on the fermentation wort with banana adjunct using a factorial design 22, in the micro-brewery pilot plant located in the EEL - USP, at different concentrations and process temperatures. It was observed that at 12 0P and at 15 0C, it was obtained a Qp of 0.58 g/L.h in 72 h of fermentation and only 6.07 % of the sugar metabolized by the alcoholic-yeast was deviated for the production of secondary products, which guaranteed a real Yp/s of 0.48 g/g. Using these conditions in study, it was investigated the kinetic behavior of the alcoholic-yeast Saccharomyces cerevisiae 308 of law fermentation (lager type) in these wort using banana, of conventional gravity. It can be observed that the maximum value of ?x (0.114 h-1) was achieved with fermentation at 12 0P and 150C. The maximum values of ?s and ?p (1.128 e 0.585 g/g.h, respectively) was obtained at fermentation of 15 0P and 15 0C. It was also done studies with the objective of increasing the volumetric productivity of ethanol in worts with banana at high gravity. For this reason, it was done several fermentations with the addition of different nutrients, in mini-bioreactors cylindrical-conical de 0.9 L from UMinho-Portugal. It was verified that the addition of MgSO4 was statistically significant for the increase in Qp. It was also verified that the best value of Qp (0.68 g.L/h) was achieved in 64 h of fermentation after being supplemented with 420 mg/L of MgSO4. It was also done a physical-chemical characterization of the beer obtained from the reproduction of the optimized experiment obtained using the cylindrical-conical bioreactor de 0.9 L from UMinho- Portugal in the bioreactor of 180 L of working volume located in the EEL - USP, verifying that the beer with banana (4.8 % v/v) have presented a high concentrations of potassium (600.68 mg/L) and isomile acetate (1.20 mg/L). It was done a sensorial evaluation of the elaborated beer in the pilot-plant in the USP, comparing it with the other beers found in the Brazilian market. It was observed that in relation to the preference test, beers with banana were statistically preferred in relation to the other samples. Acceptance tests demonstrated that there has been no significant difference (p>= 0.05) in relation to the grade of acceptance between the products corresponding to the samples taken from the optimized experiments and the samples taken from the market. In other words, the samples with banana were acceptable by the consumer as much as the samples taken from common beers found in the market. Finally, it was done a preliminary economical evaluation of the process, considering as production capacity the value of 875 L/month of beer with banana. It was calculated the initial cost of the process was of 204.76% superior than the commercial draft beer. On the other hand, the direct cost of production of this draft beer was of R$ 0.94/L against R$ 1.10/L of draft beer made from pure malt using the same process conditions.

Marayniyoq, un establecimiento wari en el valle de Ayacucho, PerúValdéz, Lidio M., Valdéz, Ernesto, Bettcher, Katrina, Vivanco, Cirilo 10 April 2018 (has links)
Marayniyoq, A Wari Establishment in Ayacucho Valley, PerúIn this paper we discuss the initial results of archaeological excavation carried out at Marayniyoq, a specialized Wari facility in the Ayacucho Valley, Peru. The discovery of a series of flat worked stones used for grinding, along with rocker grinders strongly suggests that the role of Marayniyoq was focused on grain processing, probably grinding corn. Because the grinding stones are immense cut blocks it is also apparent that enormous human energy was invested in the preparation, transportation and final setup of the facility. At the same time, the presence of large ceramic vessels and other evidence suggests that the function of Marayniyoq was the grinding of malted corn (qora) for corn-beer production. / En este trabajo se dan a conocer los resultados de las excavaciones efectuadas en Marayniyoq, un centro especializado wari del valle de Ayacucho. El descubrimiento de una serie de batanes y sus respectivas moliendas indican que éste fue un establecimiento destinado al procesamiento de granos, como el maíz. Puesto que estos batanes consisten en grandes bloques de piedra labrada, queda también manifiesto que se invirtió una enorme actividad humana en su preparación, traslado y construcción final. A su vez, la presencia de vasijas y evidencias adicionales tienden a sugerir que la función de Marayniyoq se relacionaba con el procesamiento de maíz y la producción de chicha.

El Horizonte Medio en el conjunto arquitectónico Julio C. Tello de CajamarquillaMogrovejo, Juan, Segura, Rafael 10 April 2018 (has links)
The Middle Horizon Occupation of the Julio C. Tello Complex, Cajamarquilla SiteThis paper presents results obtained by the Cajamarquilla Archaeological Project at the monumental urban center of Cajamarquilla, in the Rimac Valley, central coast of Peru. The 1996-1997 excavations in the Architectural Group Julio C. Tello exposed important burials and funeral contexts from Middle Horizon Epochs 1 and 2 as well as a room with offerings dating to Epoch 1. These remains demonstrate that Huari influences were not very significant in the origin, the development and the prestige system of the Cajamarquilla city. / El presente artículo trata sobre las investigaciones que el Proyecto Arqueológico Cajamarquilla viene desarrollando en el sitio urbano monumental de Cajamarquilla, valle del Rímac, costa central del Perú. Se exponen los resultados más importantes obtenidos durante el periodo 1996-1997 en el conjunto arquitectónico Julio C. Tello. Particularmente destaca el hallazgo de varios contextos funerarios de las épocas 1 y 2 del Horizonte Medio y un recinto con pozos de ofrendas de la Época 1. A partir de esta evidencia, los autores sostienen que las influencias huari no parecen haber sido demasiado trascendentes en el origen, funcionamiento y prestigio del sitio.

Fábrica de cerveza artesanal en Pachacamac / Craft beer factory in PachacamacVergara Meléndez, Adriana Ofelia 19 April 2021 (has links)
La tesis a continuación presenta el desarrollo de una Fábrica de Cerveza Artesanal en el distrito de Pachacamac. La cual se propone como respuesta a la problemática actual en la ciudad de Lima con respecto a sus zonas productivas, ya que, tanto la industria pesada como la artesanal, no consideran una integración adecuada con la ciudad y no incluyen al visitante como usuario. Esto crea límites cerrados hacia el entorno inmediato, contribuyendo a la inseguridad urbana y perdiendo la oportunidad de difundir el valor cultural de lo que están produciendo. En el caso de la cerveza artesanal, que es una industria emergente con gran acogida, además de la problemática antes mencionada, su producción se realiza en espacios que no han sido diseñados ni preparados para esta actividad. Por lo que se plantea esta fábrica con usos complementarios, que hacen de este proyecto algo sostenible en el tiempo, ya que no solo considera a los usuarios destinados a la producción, sino también al usuario que le da valor cultural, gastronómico y turístico a la industria de la cerveza artesanal. / The thesis below presents the development of a Craft Beer Factory in the district of Pachacamac, which is proposed as an answer to the current problems in the city of Lima with respect to its productive areas, since both heavy industry and artisanal, do not consider an adequate integration with the city and do not include the visitor as a user, creating closed limits towards the immediate environment, contributing to urban insecurity and losing the opportunity to spread the cultural value of what they are producing. In the case of craft beer, which is an emerging industry, with great reception, its production is carried out in spaces that have not been designed or prepared for this activity, in addition to the aforementioned problems. That is the reason why this factory is proposed with complementary uses, which make this project something sustainable over time, since it not only considers the users destined for production, but also the user who gives cultural, gastronomic and touristic value to the craft beer industry. / Tesis
