<p>The procedure consists of: 1. extraction of pulverised plant substance by organic solvent or solvent mixture at a temperature between 0 and 100 degrees Celsius, subsequent rapid cooling and separation of etheric oils, 2. processing of plantskins by water or vapour, 3. evaporation of solvents or solvent mixture, 4. isolation of antioxidative components, which is performed by saturating the concentrated solution by an inert gas and expansion of the concentrated saturated extract solution, 5. destillation of the remnant by vapour, 6. cooling of the suspension of the extract of antioxidative components and separation of the buck, 7. drying the extract of antioxidative components. The resulted products are of extremely high quality since the content of the antioxidative components is extremely high, while the technological process is simpler compared to all the procedures described so far.</p> |
