Characterization and drying of caja bagasse (Spondias mombin L.) in a tray dryer using a factorial planning Rev. Bras. Frutic.
Silva,Andréia Souto da; Oliveira,Edson Leandro de; Santos,Everaldo Silvino dos; Oliveira,Jackson Araújo de.
The caja (Spondias mombin L.) is used in the manufacture of ice-cream, jams, pulps, beverages being also consumed in natura. One of the most important procedures in food conservation is drying, considering that most fresh fruits contain approximately 80% of water. Food drying is used to obtain two basic aspects: (1) the economic factor; in the shipping and handling of the product; (2) at the manipulation; once dried and grinded, the material is rehydrated, at desirable levels, to formulate a new product as in ice cream, jams, yoghurts and drinks and may also be added to pasta, biscuits and other industrialized products. The aim of this study was to investigate the kinetics of caja bagasse drying in a fixed-bed tray dryer, using central composite factorial...

Modulation of antimicrobial metabolites production by the fungus Aspergillus parasiticus BJM
Bracarense,Adriana A.P.; Takahashi,Jacqueline A..
Biosynthesis of active secondary metabolites by fungi occurs as a specific response to the different growing environments. Changes in this environment alter the chemical and biological profiles leading to metabolites diversification and consequently to novel pharmacological applications. In this work, it was studied the influence of three parameters (fermentation length, medium composition and aeration) in the biosyntheses of antimicrobial metabolites by the fungus Aspergillus parasiticus in 10 distinct fermentation periods. Metabolism modulation in two culturing media, CYA and YES was evaluated by a 2² full factorial planning (ANOVA) and on a 2³ factorial planning, role of aeration, medium composition and carbohydrate concentration were also evaluated. In...

Pharmaceutical development of tablets containing a spray-dried optimized extract from Lippia origanoides H. B. K.: influence of excipients and toxicological assessment BJPS
Coelho,Angélica Gomes; Lima Neto,José de Sousa; Moura,Arkellau Kenned Silva; Morais,Ilmara Cecilia Pinheiro da Silva; Cunha,Francisco Valmor Macedo; Melo-Neto,Bernardo; Medeiros,Maria das Graças Freire de; Vasconcelos,Eilika Andreia Feitosa; Arcanjo,Daniel Dias Rufino; Nunes,Lívio Cesar Cunha; Citó,Antônia Maria das Graças Lopes.
ABSTRACT Lippia origanoides is a honey shrub which has showed hypotensive potential assessed by in vivo studies. The aim of this work is the development of a pharmaceutical formulation composed by an optimized extract obtained from aerial parts of L. origanoides. The quantification of the naringenin marker in the dry extract and tablets developed was performed, as well as the assessment of the oral acute toxicity in rats. The hydroalcoholic extract of L. origanoides was spray-dried with the addition of colloidal silicon dioxide (Lo-HAE/CSD), and then applied in the preparation of eight different lots of tablets. The influence of the diluent (cellulose or babassu mesocarp), the presence of binder, and the percentage of lubricant, as well as organoleptic and...

Sucrose hydrolysis catalyzed by auto-immobilized invertase into intact cells of Cladosporium cladosporioides Electron. J. Biotechnol.
Santana de Almeida,Ana Cláudia; Costa de Araújo,Luciares; Mendes Costa,Andressa; Moraes de Abreu,César Augusto; Gomes de Andrade Lima,Maria Alice; Perez Fernandez Palha,Maria de Los Angeles.
The enzyme known as invertase (E.C. 3.2.1.26 - β-D-fructofuranosidase) catalyzes the sucrose hydrolysis producing an equimolar mixture of glucose and fructose named inverted sugar. The fungus Cladosporium cladosporioides has invertase as its constituent. Hence, its use as a natural immobilized support for the invertase produces interesting results for the enzyme. The present work has the objective of determining the optimum operational conditions of auto-immobilized invertase, as well as its kinetic parameters (K M and Vmax). A complete 2³ factorial planning was done for the evaluation of such parameters. Temperature, pH and agitation level were the studied variables. The hydrolysis percentage was the monitored result. Batch tests in optimum...
