Pulsed Electric Fields (PEF) as pre-treatment for freeze-drying of plant tissues

Description

The influence of pulsed electric fields (PEF) treatment on freeze-drying forpotato and strawberry tissues was investigated. Samples were pre-treated by PEF (E=400 V cm-1) for different treatment times. Freeze-drying was carried out at -17°C and 18.4 Pa or 30 Pa for potato and strawberry tissues, respectively.The effects of PEF pre-treatment was compared with intact samples. The drying time was reduced by 35% for potato and 30% for strawberry. The sample rehydration capacity and the electrolytes released during the rehydration were higher for pre-treated samples. Strawberries texture was characterized by the hardness, the cohesiveness and the springiness. (Author)
