<p>The present invention relates to a method for extracting juice from a vegetal raw material (biomass), wherein said method involves using the energy of a microwave field for heating said raw material at a temperature of between 45 and 55° C, coagulating impurities and extracting the useful substances from the cells of the vegetal raw material (proteins, vitamins, carbohydrates, etc.). The coagulation process is carried out in a direct-current electric field having an intensity of between 2 and 12 W/cm. This invention also relates to a method for removing the iron contained in the juice. This method can be used for improving the juice quality by increasing its purity level, while preserving as much as possible the biochemical and the microbiological components of the vegetal cells. When applied on a vegetal raw material containing spiruline algae, this method produces a juice with a purity of up to 98.8 %, compared with the 80 % purity obtained from the prototype.</p> |
