The aim of this experimental work was to evaluate the influence of wheat dextrin addition on rheological characteristics of the wheat dough and on technology and nutritional biscuit quality. The effect of replacing part of the wheat flour (0, 5, 10 and 15%) by wheat dextrin on the rheological characteristics of the dough was investigated using farinograph and extensograph measurements. Three commercial wheat flours ranked as weak, intermediate and strong were used for this purpose. Dough stability increased upon addition of wheat dextrin, except for wheat flours such as intermediate and strong containing 15% of dextrin. At all level of replacement of dextrin by wheat flour, significant decrease in water absorption was observed for all wheat flours tested. Weak and strong wheat dough with 5% of dextrin has not influence on ratio R/E. Up to certain levels, wheat flour could be replaced by wheat dextrin without compromise the dough consistency. A short-dough biscuit recipe with different levels of wheat flour replacement (0, 7, 14 and 21%) by wheat dextrin was tested. Physical, mechanical, sensory and nutritional characteristics of the biscuits were evaluated. Sensory attributes such as crispness was improved with 7% of dextrin, flavor and global acceptance have higher rates with 21%, comparing to biscuits without dextrin. The general acceptance was better to the enriched fiber biscuit. The thickness, specific volume and spread of the biscuits were not negatively affected due to dextrin. There was significant increase in the width of the biscuits with 21% of wheat dextrin. Water activity and moisture content showed augment with addition of 14 and 21% of dextrin. Addition of wheat dextrin to biscuit promoted a yellowness color. Crispness perception of the biscuits with wheat dextrin was better than the common biscuit, both under compression and shear forces. Fiber analysis showed a significant increas e of soluble fiber values until 12.28% to the read-to-eat biscuits.Protein content of the biscuits showed values between 11.83 and 13.17%. Addition of wheat dextrin into biscuits formulation could be useful to adjust rheological parameters of dough towards target values. Addition of 21% of dextrin to biscuit showed acceptable properties, as well as higher soluble fiber content with lesser effect on sensorial neither physical properties of biscuit, which could causes rejection by consumers. / A dextrina de trigo pode ser classificada como uma fibra solúvel e entre alguns de seus benefícios estão a regulação do sistema digestivo, a estabilização do nível de glicose no sangue e a regulação dos lipídeos séricos. O objetivo desta pesquisa foi avaliar a influência da adição de dextrina de trigo sobre as características reológicas da massa de farinha de trigo e a qualidade tecnológica e nutricional de biscoitos. O efeito da substituição de parte da farinha por dextrina (0, 5, 10 e 15%) sobre as características reológicas da massa foi investigado por meio de farinografia e extensografia. Três farinhas de trigo diferentes foram utilizadas e classificadas como fraca, média e forte. A estabilidade de todas as farinhas aumentou com o aumento de dextrina, exceto das farinhas média e forte com 15% de dextrina. Houve redução significativa da absorção de água, em todos os níveis de substituição por dextrina, para todas as farinhas. Não houve diferença entre a relação R/E das farinhas fraca e forte com 5% de dextrina. A adição de dextrina de trigo em biscoitos pode ser útil para se ajustar a reologia da massa e evitar prejuízos ao processo. Uma formulação de biscoito de massa curta com diferentes níveis de substituição de farinha (0, 7, 14 e 21%) por dextrina foi testada. Características tecnológicas e nutricionais dos biscoitos foram avaliadas. Em relação aos atributos sensoriais, a adição de 7% de dextrina melhorou a crocância e a adição de 21% melhorou o sabor e a aceitação geral dos biscoitos, em comparação ao biscoito sem dextrina. A espessura, a expansão e o volume específico dos biscoitos não foram impactados negativamente. Houve um aumento significativo no diâmetro dos biscoitos com 21% de dextrina. A atividade de água e umidade dos biscoitos aumentaram com a adição de 14 e 21% dextrina. As amostras com adição de dextrina tiveram uma coloração mais amarelada. O biscoito com adição de 7% de dextrina apresentou maior fragilidade à compressão. A adição de dextrina aumentou a resistência ao cisalhamento dos biscoitos. Análises de fibra demonstraram aumentos significativos de fibras solúveis, até valores de 12,28% do produto final. Os níveis de proteína encontrados nos biscoitos variaram de 11,83 à 13,17%. Em relação ao biscoito, a adição de 21% de dextrina parece ser o mais indicado, já que possibilitou o maior incremento de fibras solúveis e não prejudicou as características sensoriais nem físicas do biscoito, ao ponto de tornar o mesmo inaceitável do ponto de vista do consumidor.

The development of Amadumbe (Colocasia esculenta (l.) schott)-soya composite biscuits with improved nutritional and sensory properties

Mokhele, Tabea Mokgalakane 06 1900 (has links)
The Amadumbe crop [Colocasia esculenta (L.) Schott] is a traditional Southern African tuber crop which is rich in starch, mucilage and micronutrients. Amadumbe tubers have limited amount of proteins and as a result, amadumbe-processed foods lack adequate protein. The purpose of this study was therefore to develop protein-rich amadumbe-soya composite biscuits, which would be acceptable to consumers. Biscuits were prepared by combining amadumbe and soya flours at ratios: 90:10, 70:30 and 50:50. Functional properties of composite flours and the physical properties of composite biscuits were determined. The proximate composition, amino acid composition and protein digestibility of composite biscuits were determined. Consumer acceptability test of biscuits was performed using nine-point hedonic scale. The results indicated that the 90% amadumbe and 10% soya composite biscuits had high significant values of moisture, ash, carbohydrates contents and energy values. The 50% amadumbe and 50% soya composite biscuits had significantly high values of fat, crude protein contents and acid detergent fibre (ADF). The protein digestibility, amino acid contents, especially the lysine contents of composite biscuits increased significantly (p ≤ 0.05) with an increase in the percentage of soya. The mineral contents of composite biscuits; Ca, Mg, P, Zn, Cu, Mn and Fe increased significantly (p ≤ 0.05) with the increase of soya in the composite biscuits. There was a significant difference in the mean taste acceptability and mean overall acceptability when the soya concentration was increased to 50%. Soya was successfully used to produce amadumbe composite biscuits with better nutritional quality with respect to protein content, amino acid profile and selected mineral contents and which were acceptable to consumers. / National Research Foundation (South Africa) / Life and Consumer Science / M.Sc.

Sour cassava starch is produced without an established standard of quality, with hygiene problems in processing, as well as product availability during the years. Still the production technology is not standardized, as well as the characterization of this product. This study has the objective of characterizing baked products with native and modified cassava starches for baked foods and tests a new formulation including the byproduct okara. In this work, commercial samples of cheese bread, cassava starch biscuits, chipa paraguaya as well as cassava starch, sour cassava starch and modified cassava starches were compared in terms of physicochemical properties. The quality characteristics of cheese bread, cassava starch biscuits and cheese bread supplemented with 5, 10 and 15% of okara were investigated. The characteristics of sour starch that makes it different from cassava starch are pH, acidity, degree of expansion, viscosity, clarity of the starch paste, freeze-thaw stability and reducing power. Four different starches were applied in the production of the baked products: cassava starch, sour cassava starch, starch modified with hydrogen peroxide and the modified starch named ExpandexÒ 160003. The baked products were evaluated in order to establish their physicochemical properties and observe the influence of the different starches on sensory evaluation. The results showed that the cheese breads supplemented with the byproduct okara had an increase in the protein and dietary fiber contents. The baked foods were submitted to an acceptability sensory evaluation with a nine point hedonic scale, involving untrained panelists. For the cheese bread samples containing sour starch cassava, starch modified by oxidation with hydrogen peroxide and the commercial starch ExpandexÒ 160003 resulted in close acceptability. For the cassava starch biscuits it was possible to conclude that the sour cassava starch and ExpandexÒ 160003 did not differ statistically. The cheese breads made with 5, 10 and 15% of okara were not statistically different at the level 5% and had good acceptability. / O polvilho é utilizado como ingrediente principal na fabricação de biscoitos e de pão de queijo. O polvilho azedo é um produto artesanal, sem padrão de qualidade estabelecido, com problemas de higiene em seu processamento e de oferta. Ainda não está padronizada a tecnologia de produção, assim como a caracterização ou tipificação desse produto. O trabalho teve como objetivo caracterizar produtos panificados contendo féculas de mandioca para uso culinário e modificadas e testar novas formulações, incluindo o subproduto da obtenção do extrato aquoso de soja - okara. Neste trabalho, pré-misturas de pão de queijo, biscoito de polvilho, chipa paraguaya e amostras de polvilhos doce, azedo e modificados foram comparadas físico-quimicamente. As características de qualidade de pão de queijo, biscoito de polvilho e pão de queijo suplementado com 5, 10 e 15% de okara foram investigadas. As características do polvilho azedo que o difere do polvilho doce são: pH, acidez, grau de expansão, viscosidade, claridade de pasta, sinérese e poder redutor. Foram aplicados nos produtos panificados quatro tipos diferentes de fécula, sendo polvilho doce, azedo, fécula modificada com peróxido de hidrogênio e fécula modificada comercial ExpandexÒ 160003. Obtidos os produtos panificados, foi determinada a composição físico-química e observado que os tipos de féculas influenciaram nas características internas, externas e no sabor. Os pães de queijo suplementados com subproduto okara apresentaram uma elevação do teor de proteínas e de fibras alimentares. Os produtos panificados foram submetidos a análise sensorial de aceitabilidade utilizando-se a escala hedônica de nove pontos, com provadores não-treinados. As amostras de pão de queijo contendo polvilho azedo, fécula modificada oxidada com peróxido de hidrogênio e fécula modificada comercial ExpandexÒ 160003 obtiveram uma aceitação próxima. Para as amostras de biscoito de polvilho verificou-se que as com polvilho azedo e ExpandexÒ 160003 não diferiram estatisticamente. Pães de queijo com 5, 10 e 15% de okara não foram consideradas diferentes significativamente em nível de 5% e tiveram boa aceitação.

Cheese breads and sour cassava starch biscuits are examples of gluten free baked products widely consumed in Brazil, however, these products have problems related to starch retrogradation, in other words, a very rapid staling in the case of baked products and the cheese breads marketed as frozen dough are susceptible to release of water (syneresis). Thus, the objective of this study was to develop a anti-staling premix able to increase freeze-thaw stability of gluten free baked products (cheese bread and sour cassava starch biscuits) without interfere negatively on the expansion property of these products. Binary and ternary mixtures were prepared using native cassava starch and oxidized cassava starch ranging the type of gum (guar, locust, xanthan and carrageenan) and the concentration used (2, 4 and 6 %). Mixtures using the acid modified cassava starch instead of oxidized cassava starch were also tested, but in this case using only guar gum at concentrations of 2, 4 and 6 %. The mixtures were evaluated for freeze-thaw stability and expansion property and the results were compared with those obtained for sour cassava starch (PA) native cassava starch (N), oxidized cassava starch (O) and acid modified cassava starch (A). The binary and ternary mixtures with better results and samples PA, N and O were evaluated for technological properties (pasting properties, swelling power and solubility and paste clarity), thermal properties (Differential Scanning Calorimetry - DSC), structural properties (Fourier Transform Infrared Spectroscopy - FTIR) and crystalline properties (X-ray diffraction); moreover, cheese breads were prepared with these samples and the staling of these products was evaluated (hardness parameter in texturometer and crumb moisture content). The mixture made with the native cassava starch, oxidized cassava starch and guar gum at a concentration of 4 % (MNO+GG 4 %) showed the best results of syneresis (loss of 4,87; 7,79 and 11 % in the 1st, 2nd and 3rd freeze-thaw cycle, respectively) compared with the other samples and the low retrogradation of this sample was confirmed by DSC analysis (enthalpy of retrogradation was non-existent) and FTIR (sample separated from others by principal component analysis - PCA). The expansion property of MNO GG+4 % sample was high (> 10 mL.g-1) and the cheese breads developed with this sample had a later staling compared with other samples, with lower hardness after 24 and 30 h of storage (23.71 and 29.59 N, respectively) and a wetter crumb (38.8 and 37.07%, respectively). These results indicate the possibility of using the premix MNO+GG 4% in gluten free baked products in place of sour cassava starch and/or native cassava starch. / O desenvolvimento de produtos livres de glúten está se tornando cada vez mais importante uma vez que o número de pessoas celíacas tem aumentado. Pães de queijo e biscoitos de polvilho são exemplos de produtos panificados livres de glúten consumidos em território brasileiro, porém, estes produtos possuem problemas relacionados com a retrogradação do amido, ou seja, um envelhecimento muito rápido no caso de produtos assados e os pães de queijo comercializados na forma de massa congelada estão susceptíveis à liberação de água (sinérese). Dessa forma, o objetivo do presente trabalho foi desenvolver uma pré-mistura capaz de retardar o envelhecimento e aumentar a estabilidade ao congelamento-descongelamento de produtos panificados livres de glúten (pães de queijo e biscoitos de polvilho), além de não interferir negativamente na propriedade de expansão dos mesmos. Misturas binárias e ternárias foram elaboradas utilizando-se o amido de mandioca nativo e o amido de mandioca oxidado variando-se o tipo de goma (guar, locusta, xantana e carragena) e a concentração utilizada (2, 4 e 6 %). Misturas utilizando o amido de mandioca ácido modificado ao invés do amido de mandioca oxidado também foram testadas, mas neste caso utilizando somente a goma guar nas concentrações de 2, 4 e 6 %. As misturas foram avaliadas quanto à estabilidade a ciclos de congelamento-descongelamento e propriedade de expansão e os resultados foram comparados com os obtidos para o polvilho azedo (PA), amido de mandioca nativo (N), amido de mandioca oxidado (O) e amido de mandioca ácido modificado (A). As misturas binárias e ternárias com melhores resultados e as amostras PA, N e O foram avaliadas quanto às propriedades tecnológicas (propriedade de pasta, poder de intumescimento e solubilidade, e claridade de pasta), térmicas (calorimetria exploratória diferencial - DSC), estruturais (Espectroscopia de infravermelho por transformada de Fourier - FTIR) e cristalinas (difração de raios X); além disso, foram elaborados pães de queijo com essas amostras e o envelhecimento dos mesmos foi avaliado (parâmetro dureza em texturômetro e teor de umidade dos miolos). A mistura feita com o amido de mandioca nativo, amido de mandioca oxidado e goma guar na concentração de 4 % (MNO+GG 4 %) apresentou os melhores resultados de sinérese (perdas de 4,87; 7,79 e 11 % no 1º, 2º e 3º ciclo de congelamento-descongelamento, respectivamente) em comparação com as demais amostras e a baixa retrogradação desta amostra foi confirmada pela análise de DSC (entalpia de retrogradação foi inexistente) e FTIR (amostra separada das demais pela análise de componentes principais – PCA). A propriedade de expansão da amostra MNO+GG 4 % foi considerada elevada (>10 mL.g-1) e os pães de queijo desenvolvidos com esta amostra tiveram um envelhecimento mais tardio em relação as demais amostras, apresentando menor dureza após 24 e 30 h de armazenamento (23,71 e 29,59 N, respectivamente) e um miolo mais úmido (38,8 e 37,07 %, respectivamente). Esses resultados indicam a possibilidade de utilização da pré-mistura MNO+GG 4 % em produtos panificados livres de glúten, em substituição do polvilho azedo e/ou amido de mandioca nativo.
