Effects of Pulsed Electric Field Treatment on Compression Properties and Solutes Diffusion Behaviors of <i>Jerusalem artichoke</i>
<i>Jerusalem artichoke</i> is widely used as raw material for industrial production of inulin. Pressing (compression) and diffusion are two effective technologies for bio-compounds’ recovery from plants. In this work, pulsed electric field (PEF) treatment at 400, 600, and 800 V...
