Use of fibres obtained from the cashew (Anacardium ocidentale, L) and guava (Psidium guayava) fruits for enrichment of food products

With the purpose of using the cashew and guava dried bagasse for enrichment of cookies, a study of drying process was done. The physico- chemical characterization included the determination of pH, soluble solids, total acidity, protein, lipids, fiber, ash, moisture and total and reducing sugars. Total coli forms, yeasts and molds counting were the microbiological analyses conducted. Enriched cookies were prepared by adding 5, 10 and 15% (of total weight) of dry residues of cashew and guava. Appearance, color, odor, taste and texture were the sensorial attributes evaluated for the enriched and non-enriched cookies. The granulometric analysis defined that more adequate particle to add were between 65 and 100 mesh. The enriched cookies with cashew and guava fibers in 10% e 5%, respectively, showed a high rate of acceptability in relation to flavor.

El objetivo del trabajo presentado aqui fue la evaluacion de un modelo cinetico que representa el secado del cefalotorax de camaron, en capa delgada. Se realizaron varios experimentos en secador de lecho fijo, con velocidad superficial media de aire variando entre 0.2 y 0.4 m/s y temperatura de 50 a 70o C. Las curvas de secado presentaron un periodo de calentamiento seguido de periodos de velocidad decreciente, y no se observo el periodo de velocidad constante. Debido a las caracteristicas del material se considero que en el periodo de velocidad decreciente la humedad se dirige hacia la superficie, predominantemente por difusion molecular a traves del medio poroso. Por este motivo, el estudio cinetico fue realizado por medio de un modelo difusional. La validez del modelo fue evaluada usando el coeficiente de correlacion, el error Standard y el error absoluto medio porcentual como criterios estadisticos de ajuste, encontrandose que el modelo representa bien la cinetica de secado estudiada.
