Abstract
The present invention relates to a method for treating biological organic tissue, particularly plant tissue, by applying a direct current preferably of low voltage electrical field for short duration, with minimal detrimental influence on the treated tissue and to further beneficial uses of the residual tissue mass. The system and methods are useful for extraction and separation of substances of interest from the biological tissue, with optional concomitant reduction in enzyme activity, resulting in delayed or arrested browning of the tissue, and for production of imprint marks on the treated tissue. The present invention further relates to substances including pigments, minerals, oils, fragrances, vitamins, amino acids, alkaloids, extracted using the direct current treatment system, and to apparatus for performing the treatment.
