The effect of the pulsed electric field (PEF) pretreatment on convective drying of red beetroot tissue was investigated at the drying temperatures Td in the interval 30-100°C. The degree of material damage Z under the PEF and thermal treatment was studied. Dependence of the electrical characteristic damage time τE on the electric field strength E and the thermal characteristic damage time τT on temperature Td is discussed. The drying rate is shown to be maximal for highly disintegrated tissues; PEF pretreatment allowed reduction of the drying temperature by 20-25°C. PEF pretreatment results in greater degree of tissue shrinkage and hence increase in rehydration time; however, the textural properties of rehydrated samples with and without PEF treatment are seen to be similar. The benefit of PEF pretreatment for drying at moderate temperatures with preservation of colorants is also demonstrated. |
