Foam mat drying kinetics of jambolan and acerola mixed pulp

ABSTRACT Acerola and jambolan are fruits with several bioactive compounds of phenolic origin a product made these two raw materials appears to be food high antioxidant nutraceutical potential. Therefore, this study aimed evaluate the foam mat drying mixed pulp acerola. Mixed formulations, containing 1.0% albumin 0.5% xanthan gum (F1), carboxymethylcellulose (F2) guar (F3), were dehydrated at 50, 60, 70 80 °C, thickness 0.5 cm. The elevation temperature decreased water content dehydration time samples. Formulation F3 obtained shortest times; all models resulted in good adjustments, especially Midilli. greater effective diffusivity; activation energy was higher F1 combination. samples albumin-guar (F3) showed enthalpy entropy albumin-xanthan (F1) highest Gibbs free energy. Foam is an efficient way preserving acerola pulp.
