Résumé : |
Often, osmotic shock, oxidative stress and de-compartmentalization in dried plant cells negatively impact efficacy, bioavailability, functional properties, safety and reproducibility of conventional botanical extracts. This prompted the development of a sustainable solvent-free Zeta Fraction Technology (ZFT), which is based on scientific principles discovered by Van't-Hoff and Debye, and on Derjaguin-Laundau-Verwey-Overbeek (DLVO) theory. Progress in life sciences and in instrumentation for broadband dielectric spectrometry has contributed to the development of IFT. This technology includes : collection of living plants with maximum metabolic activity ; separation of relatively stable intracellular colloidal dispersion (lCD) from cell walls ; treatment of ICD to engage particular components of the dispersed phase and continuous phase in specific interactions by changing the balance between repulsive and attractive forces ; and separation of ICD to different Zeta Fractions. Plant examples including Sacred Lotus (Nelumbo nucifera), Tea Plant (Camellia sihensis). Feverfew (Chrysanthemum parthenium) and Sage (Salvia officinalis) demonstrate that ZFT allows targeting multiple pathways with a single ingredient, improving safety by removing undesirable components and chemicals of concern, all white resulting in minimal environmental impact and waste. ZFT utilizes the underexplored potential of living plants and may be used in combination with existing extraction technologies to achieve effective volume reduction. |
