Development of cassava cake enriched with its own bran and Spirulina platensis

The cassava cake was developed enriching it with a biomass of Spirulina platensis and a type of bran made out of its own starch. This biomass, a part from being rich in protein, also contains vitamins, essential fatty acids and minerals. Around Umuarama, in the State of Parana, there is an agricultural/industrial complex annually producing and processing tons of cassava. Baked goods can be elaborated based in cassava as a way to expand the use of this raw material and to produce food free of gluten to celiac people. In this complex a solid byproduct is generated, which is rich in starch and fibres, and because of its low commercial value it is used for animal feed or discarded. The bran was dehydrated and analysed microbiologically as well as physically and chemically so as to be used in applied research. Developed energetic food based on cassava lacks protein, but this can be supplied by adding the biomass of Spirulina platensis. Different formulations of this cassava cake were developed varying the concentration of Spirulina platensis and cassava bran. The formulation that presented the best features received chocolate before being submitted to sensory tests by children in the public education system. The results show an excellent acceptance which made viable the development of this product because of aspects like nutrition, technology and sensorial.

Performance of juveniles of Pseudoplatystoma fasciatum fed graded levels of corn gluten meal

The objective of this work was to evaluate corn gluten meal (CGM) as a substitute for fish meal in diets for striped catfish (Pseudoplatystoma fasciatum) juveniles. Eight isonitrogenous (46% crude protein) and isoenergetic (3,450 kcal kg(-1) digestible energy) diets, with increasing levels of CGM - 0, 6, 12, 18, 24, 30, 36, and 42%-, were fed to juvenile striped catfish (113.56 +/- 5.10 g) for seven weeks. Maximum values for weight gain, specific growth rate, protein efficiency ratio and feed conversion ratio, evaluated by polynomial quadratic regression, were observed with 10.4, 11.4, 15.4 and 15% of CGM inclusion, respectively. Feed intake decreased significantly from 0.8% CGM. Mesenteric fat index and body gross energy decreased linearly with increasing levels of CGM; minimum body protein contents were observed with 34.1% CGM. Yellow pigmentation of fillets significantly increased until 26.5% CGM, and decreased from this point forth. Both plasma glucose and protein concentrations decreased with increased CGM levels. The inclusion of 10-15% CGM promotes optimum of striped catfish juveniles depending on the parameter evaluated. Yellow coloration in fillets produced by CGM diets can have marketing implications.

Effect of incorporation of amaranth on the physical properties and nutritional value of cheese bread

At the present celiac disease has no known cure, and its only treatment is a strict lifelong adherence to a gluten-free diet. Cheese bread is a traditional Brazilian product and a safe option for celiacs. However, like other gluten-free breads, it has inherent low levels of fibers and minerals. The objective of this study was to evaluate the effect of incorporation of whole amaranth flour on the physical properties and nutritional value of cheese bread. Amaranth flour was incorporated at 10, 15, and 20% proportions in different formulations. The increasing amaranth levels darkened the product, reduced specific volume, and increased compression force. Ten percent amaranth-content cheese breads exhibited slight differences in physical properties compared with the controls. These results demonstrated the possibility of incorporating 10% of whole amaranth flour in the formulation of cheese bread resulting in a product with higher dietary fiber and iron contents and the same level of acceptance as that of the conventional formulation. The aim of this approach is to increase the availability of gluten-free bakery products with added nutritional value contributing to increase the variety of the diet of celiac patients.

Efeito da adição de amido resistente de milho e enzimas sobre as propriedades da massa de pão e as propriedades físicas do pão de forma.

O amido resistente de milho (ARM) não é digerido em humanos fornecendo benefícios para a saúde tais como redução do colesterol, do índice glicêmico e fermentação no cólon. Porém, a substituição parcial de farinha de trigo (FT) por ARM em massa de pão resulta na diluição do glúten prejudicando a qualidade do produto. Massa de pão foi produzida com 12,5 g/100g de ARM e os efeitos das enzimas glicose-oxidase (Gox), tranglutaminase (TG) e xilanase (HE) na massa foram estudados. Massa produzida sem ARM e sem enzimas foi considerada padrão e massa produzida com ARM e sem enzimas foi considerada controle para comparação. Uma metodologia foi desenvolvida para medir o torque durante o amassamento em grande escala, utilizando um reômetro dinâmico adaptado. As propriedades reológicas foram avaliadas nos testes de medidas descritivas de textura, adesividade Chen-Hoseney, extensão uniaxial Kieffer, extensão biaxial e testes oscilatórios em reômetro. Pão produzido de acordo com as formulações padrão, controle e ótima foi avaliado com relação ao volume específico (VEP), firmeza do miolo, cor e análise sensorial para o atributo preferência. As três enzimas testadas influenciaram positivamente o torque máximo atingido durante o amassamento que variou entre (8,36 e 9,38) N m. Gox e TG apresentaram efeito positivo na altura máxima desenvolvida pela massa medida em reofermentógrafo enquanto que o efeito da HE foi negativo. Uma formulação com ARM e enzimas apresentou desempenho de panificação similar a massa padrão (altura máxima ajustada igual a (45,5 ± 3,9) mm), correspondente a adição de (4, 2,5 e 0,5) mg/100g de TG, Gox e HE respectivamente (ótima). A formulação ótima apresentou adesividade, trabalho de adesão, coesividade, dureza, resiliência, resistência à extensão e extensibilidade similares a massa padrão e diferentes da massa controle. As enzimas aumentaram o índice de strain hardening reduzido pela adição de ARM. Para o pão de forma, o VEP variou entre (3,16 e 3,64) cm3/g (diferença não significativa) e o pão produzido com a formulação ótima foi o mais escolhido como preferido. Durante o armazenamento por até 7 dias, o ARM diminuiu a taxa de envelhecimento do pão enquanto que as enzimas apresentaram efeito oposto. Em geral, a substituição parcial de FT por ARM reduziu a elasticidade da massa diminuindo a qualidade do pão enquanto que as enzimas minimizaram esse efeito.

Total quality management in English language teaching:a case study in Turkish higher education

The need to improve the management of language learning organizations in the light of the trend toward mass higher education and of the use of English as a world language was the starting point of this thesis. The thesis aims to assess the relevance, adequacy and the relative success of Total Quality Management (TQM) as a management philosophy. Taking this empirical evidence a TQM-oriented management project in a Turkish Higher Education context, the thesis observes the consequences of a change of organizational culture, with specific reference to teachers' attitudes towards management. Both qualitative and quantitative devices are employed to plot change and the value of these devices for identifying such is considered. The main focus of the thesis is the Soft S's (Shared Values, Style, Staff and Skills) of an organization rather than the Hard S's (System, Structure, Strategy). The thesis is not concerned with the teaching and learning processes, though the PDCA cycle (the Action Research Cycle) did play a part in the project for both teachers and the researcher involved in this study of organizational development. Both before the management project was launched, and at the end of the research period, the external measurement devices (Harrison's Culture Specification Device and Hofstede's VSM) were used to describe the culture of the Centre. During the management project, internal measurement devices were used to record the change including middle-management style change (the researcher in this case). The time period chosen for this study was between September 1991 and June 1994. During this period, each device was administered twice within a specific time period, ranging from a year to 32 months.
