Acoustic impulse response in apple tissues treated by pulsed electric field

The influence of immersion and contact ultrasound treatment on selected properties of the apple tissue

“…The pulsed electric field treatment depends on the electroporation, i.e. the electrically induced perforation of the cell membrane which is linked with the intracellular content leakage and manifests as an increase of the tissue electrical parameters [20,37]. It means, that the value of, for instance electrical conductivity can be often linked to the intracellular structure changes and thus it could be used as indirect microstructure assessment method.…”

Enhanced Extraction from Solid Foods and Biosuspensions by Pulsed Electrical Energy

“…Another method is based on electrical conductivity measurements at low (&1 kHz) and high (3-50 MHz) frequencies [3]. Recently, the acoustically derived disintegration index was also proposed for characterization of PEF-treated tissues [41]. Figure 1 shows the characteristic time s E , which is necessary for half-damage (i.e., Z = 0.5) of the red beet tissue [89].…”

Acoustic emission as a tool to assess the changes induced by pulsed electric field in apple tissue

“…For instance, the electroporation efficiency can be calculated on the basis of the water effective diffusion coefficient (Vorobiev & Lebovka, 2006). Very interesting approach regarding the pulsed electric field treatment efficiency evaluation was presented by Grimi et al (2010). In this study the technique which was based on the measurement of the acoustic response of the gently taped sample of apple tissue, was developed.…”
