Previous issue date: 2012-06-25 / CAPES / The pasta is a food that is part of the table of the Brazilian people, possessing a high level of acceptability in all social classes. Because it is basically made up mostly of wheat flour is considered an energy food. Thus, it is vitally important that research be developed with alternative raw materials to replace partially the flour in the formulation of this mass and add the product better nutritional quality and / or sensory impairment. In this context an interesting alternative is the babassu mesocarp flour (Orbignya sp.). The objective of this research was the development of technology for the production of pasta mixed with the partial replacement of wheat flour (TF) by babassu mesocarp flour (BSF), seeking its nutritional enrichment and providing an alternative feed the population of Maranh?o. Four formulations of fresh noodles type have been developed, with the following composition: control (100% wheat flour), 90% flour + 10% flour mesocarp babassu, 85% flour + 15% of flour mesocarp babassu, 80% wheat flour + 20% babassu mesocarp flour. Were evaluated the physical, chemical and physico-chemical properties of flour and pasta, as well as microbiological and sensorial these. The data were processed by standard deviation, variance analysis and means compared by Tukey test (affective) and Dunnett's test (discriminative). The results of the chemical composition of flour mesocarp showed that this raw material has higher protein content than wheat flour, besides being rich in food fiber. The masses mixed with 10%, 15% and 20% of FMB, compared to controls, had increased the protein value of 28.85%, 41.60% and 51.68% and the fiber content was found to be 4.12 %, 5.28% and 6.51% respectively. Microbiological analyzes performed on the bodies testified that the products were hygienic and sanitary conditions. The addition of FMB to mass reduced the solids loss during cooking. Sensory evaluation showed an index of acceptability over 72% to pasta with 10% of FMB and 77.11% for the 15% mass of FMB, showing a good potential for use according to the literature and compared with the control were most appreciated by the judges. The pasta had a higher composite nutritional potential than the traditional mass and can be used as an alternative nutritional and income for the communities who live on the extraction of the babassu palm, using a piece of fruit that is usually neglected. / O macarr?o ? um alimento que faz parte da mesa do povo brasileiro, possuindo alto ?ndice de aceitabilidade em todas as classes sociais. Por ser constitu?do basicamente em sua maioria por farinha de trigo ? considerado um alimento energ?tico. Assim, ? de fundamental import?ncia que sejam desenvolvidas pesquisas com mat?rias primas alternativas que substituam parcialmente a farinha de trigo na formula??o dessa massa e que acrescentem ao produto melhor qualidade nutricional e/ou sensorial. Nesse contexto uma alternativa interessante, encontra-se na farinha de mesocarpo do baba?u (Orbignya sp.). O objetivo da pesquisa foi o desenvolvimento de tecnologia para a produ??o de massa aliment?cia mista com a substitui??o parcial da farinha de trigo (FT) pela farinha de mesocarpo de baba?u (FMB), visando seu enriquecimento nutricional e disponibilizando uma alternativa alimentar a popula??o maranhense. Quatro formula??es de massa fresca tipo talharim foram desenvolvidas, com as seguintes composi??es: controle (100% farinha de trigo); 90% farinha de trigo + 10% farinha de mesocarpo de baba?u; 85% farinha de trigo + 15% farinha de mesocarpo de baba?u; 80% farinha de trigo + 20% farinha de mesocarpo de baba?u. Foram avaliadas as caracter?sticas f?sicas, qu?micas e f?sico-qu?micas das farinhas e das massas aliment?cias, bem como as an?lises microbiol?gicas e sensorial destas. Os dados obtidos foram tratados por desvio padr?o, an?lise de vari?ncia e as m?dias comparadas pelo teste de Tukey (teste afetivo) e Dunnett (teste discriminativo). Os resultados da composi??o centesimal da farinha de mesocarpo mostraram que esta mat?ria prima possui maior teor prot?ico que a farinha de trigo, al?m de ser rica em fibra alimentar. As massas mistas com 10%, 15% e 20% de FMB, quando comparadas a controle, tiveram acr?scimo no valor prot?ico de 28,85%; 41,60% e 51,68% e quanto ao teor de fibras encontrado foi de 4,12%; 5,28% e 6,51%, respectivamente. As an?lises microbiol?gicas realizadas nas massas atestaram que os produtos apresentaram condi??es higi?nico-sanit?rias satisfat?rias. A adi??o de FMB ?s massas reduziu consideravelmente a perda de s?lidos durante o cozimento. A an?lise sensorial demonstrou um ?ndice de aceitabilidade acima de 72% para a massa com 10% de FMB e 77,11% para a massa com 15% de FMB, apresentando um bom potencial para consumo de acordo com a literatura e quando comparadas com a controle foram mais apreciadas pelos provadores. As massas aliment?cias mistas apresentaram um maior potencial nutritivo do que a massa tradicional e podem ser utilizadas como mais uma alternativa nutricional e de renda para as comunidades que vivem do extrativismo do coco baba?u, utilizando uma parte do fruto que normalmente ? desprezada.
