Bamboo shoots - an evaluation of powders obtained from the processing residues ...
Barros, Maria Gabriela Azevedo; Watanabe, Lucas Bertoldi; Aquino, Ana Carolina Moura de Sena; Amante, Edna ReginaO objetivo deste estudo foi caracterizar o resíduo sólido do beneficiamento de brotos de bambu, que corresponde a mais de 70% da matéria-prima, além das propriedades tecnológicas e remoção de cianeto. O pré-processamento foi realizado em água fervente por 30, 45, 60 e 90 minutos. As amostras de resíduos (controle, tratadas e pré-tratadas) foram secas em estufa com circulação de ar por 48 horas a 65 ± 5 °C segui...
Pulsed electric field for Escherichia coli inactivation in pumpkin juice and ne...
Santos Júnior, Luís Carlos Oliveira dos; Schulz, Matthias; Knorr, Dietrich; Amante, Edna ReginaIn this study experiments were performed using a batch pulsed electric field (PEF) system at different electric field strengths with a voltage of 35 kV and pulse frequency of 3 Hz, at 20 and 40°C, with pulse width between 0.8 and 1.0 µs, to evaluate the inactivation of Escherichia coli in pumpkin juice and nectar. The performance of the PEF technology can vary as a function of several process parameters and the...

Cunha, Iria Pedroso da; Gonçalves, Ericson Kubrusly; Nascimento, Luís Eduardo Silva; Melo, Denise Wibelinger de; Biluca, Fabíola Carina; Vitali, LucianoAraucaria angustifolia var. angustifolia and Araucaria angustifolia var. indehiscens, seeds (common pinhão and monkey pinhão) are consumed after cooking, coats and water represent waste. In this work, pinhão was submitted to different cooking conditions, the water extracts were analyzed to determine and identify their phenolic compounds content, antioxidant activity and antimicrobial potential. Cooking for 45 m...
Pretreatment on Anaerobic Sludge for Enhancement of Biohydrogen Production from...
Lamaison, Franciele do Carmo; Fragata, Rafael; Antônio, Regina Vasconcellos; Amante, Edna Regina; Reginatto, ValeriaMethods for the enrichment of an anaerobic sludge with H2-producing bacteria have been compared by using cassava processing wastewater as substrate.The sludge was submitted to three different pretreatments: 1) heat pretreatment by boiling at 98 °C for 15 min., 2) heat pretreatment followed by sludge washout in a Continuous Stirring Tank Reactor (CSTR) operated at a dilution rate (D) of 0.021 h-1, and 3) sludge ...

Perfil protéico em ovos embrionados e liofilizados de galinha com diferentes di...
Campos, Célia Maria Teixeira de; Hamad, Antônio José Simões; Amante, Edna Regina; Thapon, Jean-Louis; Nau, Françoise; Guerin-Dubiard, CatherineThis article presents the protein profile in freeze-dried chicken embryo eggs with different development periods (0, 3, 5, 7, 9, 11 days). The protein profile was determined through HPLC-reverse phase, electrophoresis SDS-PAGE and IFE-electrophoresis. Protein profile of these eggs changes according to the period of development and the change is more evident after the 5th day, where there was an increase in oval...
