Different modes of electrical (PEF and OH) or thermal (FT and H) treatments were applied to injure the biological cells in the apple tissue. Their resulting effects on electrical conductivity of completely damaged tissue were rather different. It can be due to possible generation of small air bubbles during OH treatment (Palaniappan & Sastry, 1991) and noticeable violation of the tissue structure, related to frost damage of the apple tissue. The observed kinetics of O treatment in aqueous glycerol solution was also dependent on the mode of treatment. The distribution of osmotic solution was practically homogeneous inside the disc of PEF-treated tissue and highly inhomogeneous in untreated and OH-treated samples. It can reflect the differences in porosity of the apple tissues, which can be arranged in the following sequence: PEFtreated N OH-treated N untreated. The combined electrical + osmotic treatments improved freezing and thawing processes, and changes in effective freezing tf and thawing tm times caused by application of these modes of treatment can be arranged in the following sequence: untreated N O-treated N PEF-treated N PEF + O-treated. The osmotic agent (glycerol) served as an effective cryoprotecting and texturizing agent. Deeper penetration of glycerol inside the apple tissue was accompanied by higher strengthening of the apple texture after combined treatments. Noticeable reduction of both freezing and thawing times and strengthening of the apple texture were observed in PEF-treated samples. It evidenced high potential of practical application of the PEF-assisted freezing technologies in food industry.
