Resumo
O objetivo do trabalho foi desenvolver e avaliar uma formulação para produção de pão sem glúten para celíacos utilizando polvilho azedo e farinha de mandioca. A doença celíaca ou enteropatia glúten sensível, é uma doença caracterizada por danos à mucosa do intestino delgado e má absorção. É uma enfermidade de caráter genético ativada, em indivíduos suscetíveis, pela ingestão do glúten do trigo e proteínas similares originárias de outros cereais como a aveia, centeio e cevada. A hipersensibilidade alimentar tem sido objeto freqüente de estudos clínicos e tecnológicos em busca de alternativas alimentares. Neste trabalho o polvilho azedo substituiu a farinha de trigo como responsável pela estrutura do pão e retenção de gases. A formulação inicial era: polvilho azedo 42%, sal 1%, açúcar refinado 5%, gordura vegetal hidrogenada 9%, farinha de mandioca 24%, leite em pó integral 3%, clara de ovo desidratada 12% e fermento biológico fresco 4%. A formulação foi ajustada e avaliada por metodologia de superfície de resposta com 26 tratamentos. As variáveis fixadas, mais importantes, através de ensaios prévios foram:clara desidratada , fermento fresco e farinha de mandioca moída crua. O delineamento foi central, composto com a) 8 combinações entre os níveis -1 e +1 das 3 variáveis independentes (fatorial 23) ; b) 6 combinações fixando 2 das variáveis no nível 0 e uma delas variando de -1 e +1 um ponto central, todas as variáveis no nível 0. Portanto, o delineamento usou 15 tratamentos diferentes sendo que cada combinação da parte fatorial (ítem (a) ) foi repetida 2 vezes e o ponto central ítem (c) foi repetido 4 vezes. Os dados experimentais obtidos foram submetidos a análise de variância e ao teste F ao nível de 10% de probabilidade. Os pães sem glúten foram analisados quanto as características organolépticas cor da crosta...
The objective of this study was develop and adjust a formulation for bread without gluten production for celiac using fermented cassava starch. The celiac disease or enteropaty sensitive-gluten, is a disease characteristic for damage the mucosa of the jejunal morphology malabsortion. Is a illness gluten-intolerance, in individual susceptible, ingested of wheat gluten and similar proteins of the cereal how oat, rye and barley. The food hypersensitive had been object after of the technological and clinical research in search of the food alternative. In this paper the fermented cassava starch substituded the wheat flour how responsible for structure of bread and gas retained. The basic formulation was: fermented cassava starch 42%, salt 1%, sugar 5%, hydrogenated vegetal fat 9%, ground cassava flour 24%, powered milk 3%, powered egg white 12% and yeast 4%. The formulation was adjusted and available for response surface methodology study with 26 treatments. The fixed variables more important were: powdered egg white, fresh yeast and ground cassava flour. The experiment was central composed with: a) 8 combination between the levels -1 and +1 of the 3 variables independents (factorial 23); b) 6 combination fixing 2 of the variables in the level 0 and one of them altering of -1 and +1, and it was all the variables in the level 0, one center point. Therefore, used 15 differents treatments treatments each combination of the part factorial was repeated 2 times and the center point was repeated 4 times. The experimental datas were submitted to analysis of variance and using F test at 10% probability level. Bread without gluten were analysed according to the organoloeptic characteristics, crust color, break, symmetry, crust characteristics, crumb color, structure of cells of the of crumb, crumb texture, flavor and taste, were evaluated. The instrumental analysis were made volume, texture and... (Complete abstract click electronic access below)
