Abstract | The influence of an alternative chemical pretreatment on dehydration and rehydration of an Italian ecotype pumpkin was investigated. The pretreatments consisted of soaking the slices in a diluted solution of trehalose, sucrose and NaCL. Hot air drying was performed in a convective dryer at tempertures of 55, 60, 65 and 70 C.Smples treated prior to drying showed a shorter (about 1/4) drying time,less volume shrinkage and colour changes, but showed higher rehydration capacity copared to untreated ones, especially in the range 55-65 C.Moreover, the pretreatment was effective in retention of total phenolic content and antioxidant activity. The Midilli model was the most appropriate for describing drying behaviour, while the Weibull model for rehydration. |
