Title : Influence of freezing treatment, osmotic dehydration and storage time on the rehydration of vacuum dried strawberries
Key words : rehydration, vacuum dried fruits, osmotic dehydration, storage
Summary :

Dried fruits – strawberries – were rehydrated by dipping them in water at room temperature and their rehydration characteristics were examined. The aim of this study was to analyze the influence of the preparation method (the impact of freezing treatment at -18ºC, osmotic dehydration in sucrose solution 61.5%) of raw material and storage (from 32 days to 399 days) on the rehydration of dried strawberries. Dried strawberries obtained by the vacuum method from frozen fruits have larger relative weight gain with prolongation of rehydration time than dried fruits obtained from raw strawberries. Osmotic dehydration of strawberries before vacuum drying did not cause a significant difference in rehydration of dried strawberries stored for a long period. Vacuum dried strawberries stored for about 360 days longer at ambient temperature obtained slightly lower relative weight gain and higher solids content.
