Neste estudo, objetivou-se otimizar a substituição parcial de gordura por inulina e fibra de laranja em mortadelas de peixe, mantendo seus parâmetros microbiológicos, sensoriais e físico-químicos de qualidade. Para tal, foram utilizados como substitutos de gordura, a inulina e a fibra de laranja, além da gordura vegetal hidrogenada. Foram realizadas análises microbiológicas, com estudo da vida de prateleira por um período de 70 dias. Foi realizada análise sensorial com 56 provadores não treinados, para os atributos de aparência, aroma, textura, sabor, da aceitação global e do teste de intenção de compra, além de determinar-se a composição centesimal dos produtos. Com os resultados das análises sensoriais e centesimais, otimizou-se os substitutos de gordura utilizados na mortadela. As mortadelas de peixe obedeceram aos critérios microbiológicos e físico-químicos estabelecidos pela legislação vigente no Brasil, com estabilidade satisfatória quando armazenados sob refrigeração por 70 dias. A melhor combinação de inulina e fibra de laranja minimizou o teor de gordura para 38%, com 20% de inulina e 42% de fibra de laranja, sem diminuir a qualidade das mortadelas. / The consumption of healthier foods, such as low-fat, and have the same characteristics of the original product, becomes a challenge for the food industry. This study aimed to optimize the partial replacement of fat by inulin and orange fiber in fish bologna, keeping its microbiological parameters, sensory and physicochemical quality. To this end, it was used as fat replacers, inulin and orange fiber, addition of hydrogenated vegetable fat. Microbiological analyzes were performed, with shelf life study for a period of 70 days. Sensory analysis was performed with 56 untrained, for appearance attributes, aroma, texture, flavor, global acceptance and purchase intent test, and determined whether the chemical composition of the products. With the results of sensory and chemical analysis, it is optimized them fat substitutes used in bologna. The fish bologna met the microbiological and physico-chemical criteria established by law in Brazil, with satisfactory stability when stored under refrigeration for 70 days. The best combination of inulin and orange fiber minimized the fat content to 38%, 20% inulin and 42% orange fiber, without diminishing the quality of bologna.

Míchací a hnětací zařízení. / Mixing and kneading machine

Kopáček, Petr January 2011 (has links)
This diploma work deals with design of the mixing and kneading machine which works with heated mixed components. The components consist of PET, HDPE, silica sand and additives. First, there is introduced knowledge from accessible sources, which are concerned with the theme. Then follows projection of variants and selection of suitable solution. With the help of obtained konwledge and the chosen variant is performed design proces. In the end is created a concept assemble of the machine. The design proces includes projecting of the individual parts, strength verification of the basic elements and design of heating device.
