Effects of pulsed electric fields and preliminary vacuum drying on freezing assisted processes in potato tissue
The effects of pulsed electric field (PEF) treatment and preliminary vacuum drying (VD) on
freezing assisted processes for the potato tissue were studied. The PEF treatment was done
at 600 V/cm using the protocol to insure the high level of potato disintegration. The VD was
done at sub-atmospheric pressure of p= 0.30 bar. Such conditions allowed relatively fast
dehydration accelerated by PEF treatment at low or moderate temperatures inside sample (<
50° C). Impacts of PEF and VD on freeze-thawing (FT) and freeze-drying (FD) processes …
