Convective drying of squash (Cucurbita moschata): Influence of temperature and air velocity on effective moisture diffusivity, carotenoid content and total phenols

The influence of air temperature and air velocity on convection drying of pumpkin (Cucurbita moschata - UNAPAL Abanico 75) is studied using drying kinetics and changes in the content of total phenolic and carotene compounds. The response surface methodology was used to optimize the operating conditi...

Se empleó la metodología de superficie de respuesta para optimizar las condiciones de operación en el secado de pulpa de zapallo. Los factores estudiados fueron, temperatura de secado (45 – 65 °C) y velocidad de aire (4 y 7 m.s-1). Las condiciones óptimas de secado de pulpa de zapallo fueron; 55 °C y 7m. s-1, para la temperatura y velocidad de aire respectivamente. El tiempo de secado fue 390 min aproximadamente.
