Dissertations, Theses, & Student Research in Food Science and Technology
Application of high voltage pulsed electric fields (PEF) to plant tissues increases porosity of the plant cells, enhancing juice extraction from fruits and vegetables. Red cabbage and beetroot are rich sources of bioactive compounds anthocyanins and betalains, respectively. Pulsed electric field (red cabbage: 1 kV/cm electric field strength, 0.66 µF and 20 pulses; red beets: 1.5 kV/cm electric field strength, 0.66 µF and 20 pulses) was applied to whole red cabbage and beetroot to enhance juice extraction. Total polyphenols, anthocyanins (red cabbage), betalains (beetroot) and total antioxidant activity (ABTS and DPPH) of the extracted juice ...
