Ultrasound processing to enhance drying of cashew apple bagasse puree: Influenc...
Fonteles, Thatyane Vidal; Leite, Ana Karoline Ferreira; Silva, Ana Raquel Araújo; Carneiro, Alessandra Pinheiro Góes; Miguel, Emilio de CastroThe present study has evaluated the effects of power ultrasound pre-treatment on air-drying and bioactive compounds of cashew apple bagasse. The sonication induced the disruption of cashew bagasse parenchyma, which resulted in lower resistance to water diffusion, less hysteresis, and increased rehydration rate. The processing did not affect the lignocellulose fibers or the clerenchyma cells. For sonicated sampl...
Behavior of antioxidant enzymatic system of sonicated cashew apple bagasse
Fonteles, Thatyane Vidal; Leite, Ana Karoline Ferreira; Silva, Ana Raquel Araujo da; Fernandes, Fabiano André Narciso; Rodrigues, SueliThe effects of ultrasound processing on the activity of antioxidative enzymes of cashew apple bagasse (Anacardium occidentale L.) were investigated. The changes in the activities of superoxide dismutase, catalase, and ascorbate peroxidase were evaluated for either sonicated or control samples. The stimulus from sonication has a direct effect on the production of reactive oxygen species such hydrogen peroxide, a...
Purification of cellulases of filamentous fungi Melanoporia sp.
Santiago, Maria Iane Amaral; Fonteles, Thatyane Vidal; Nascimento, Ronnyely Braz Reis do; Souza, Priscila Maria Paiva; Rodrigues, SueliCellulases are the second largest class of industrial enzymes with potential for conversion of cellulosic biomass. Filamentous fungi are traditionally used for the production of cellulolytic enzymes. Melanoporia sp. is one of cellulase-producing fungi. Although fungal cellulase production is relevant, some purification steps might be important for its characterization. The results showed that cellulases of Mela...
Desenvolvimento de uma nova bebida funcional probiótica à base de melão Cantalo...
Fonteles, Thatyane VidalThe use of fruit juices for the development of functional foods has been an alternative for people who do not want or cannot make use of fermented dairy products. The objective of this research was the development of a drink with probiotic properties trough the fermentation of melon juice by Lactobacillus casei NRRL B-442. The first stage of the work consisted of the optimization of pH and temperature of fermen...
Uso do ultrassom seguido de secagem para o aproveitamento do bagaço do pedúncul...
Fonteles, Thatyane VidalThis thesis describes some effects of high power ultrasound to the reuse of cashew apple bagasse. Thus, the objectives of this study were: 1) Develop a optimized process for sonication of cashew apple bagasse, evaluating the effect of ultrasound on enzymatic and non-enzymatic antioxidant compounds and 2) study the effects of ultrasound in drying process evaluating the effects on bioactive compounds and bioacces...
