| The aim of this work was to evaluate the effect of pulsed electric field (PEF) pre-treatment on mass transfer phenomena, water distribution and some physico-chemical parameters of osmo-dehydrated organic strawberries. For PEF treatments 100 near-rectangular shaped pulses, with fixed pulse width of 100 ms and repetition time of 10 ms were used. Electric fields strength applied were 100, 200 and 400 V/cm . Afterwards, samples were subjected to OD treatments carried out in two different hypertonic solutions (40% w/w), one with sucrose and the other one with trehalose. The results shown that PEF treatment positively affected the mass transfer during OD even at the lowest electric field strength applied (100 V/cm), partially preserving the cell... |

| In the recent years the fruit organic production has been one the most growing sectors in food industry. Strawberries are a nonclimateric fruits, susceptible to mechanical injury and they are also highly perishable, especially the organic one. Therefore, there is a need to improve the processing of these fruits in order to obtain a semi-dried or osmodehydrated products with higher shelf-life. The aim of this work was to evaluate the effect of PEF pre-treatment on mass transfer phenomena, water distribution and some physico-chemical parameters of strawberries subjected to osmotic dehydration. For the experiment the organic strawberries were purchased in a local market and stored at 4 ± 1 °C before analysing further processing. The fruits were washed and... |
