Definitions

  • the invention regards an extraction process of natural products from plant material, in the absence of solvent.
  • the obtained products are essential oils and aromatic water
  • the oils are volatile aromatic compounds that are obtained by distillation of the vapor that is created as a result of the heating of the vegetable matrix, after that the cell structures are demolished and the water in them contained is released.
  • FR-A-2787347 describes a process that provides for the extraction of oils and aromatic water from plant matrices in the absence of solvent, only taking advantage of the water contained in the vegetable structures and proceeding to the heating under vacuum and the separation of the aqueous phase from the oil. So it is a hydrodistillation process without homogenization of the vegetable matrix, in which by microwave irradiation of plant material the vegetable structures are broken. Moreover in this process heating uniformity is not guaranteed as heating treatment and vacuum conditions are contextual.
  • WO-A-9426853 defines a demolition technique of cell structures of a plant material by irradiation with microwave, aimed at extracting essential oils by hydrodistillation. Also in this case the extraction is performed in the absence of solvent and the obtained water originates from the matrix. Again in this process heating uniformity is not guaranteed as heating treatment and vacuum conditions are contextual.
  • the salt is an organic salt.
  • the salt is an inorganic salt.
  • Another characteristic is given by the fact that the vegetable matrix is heated with a hot bath to a temperature 30 degrees higher than the boiling point.
  • the vegetable matrix is homogenized with an inorganic salt, added to 20%, in order to create on the cell membrane a proper osmotic pressure to the leakage of the water and the consequent demolition of the cell structures and placed in a container 1.
  • the container 1 with the homogenized plant material is placed under vacuum, created by vacuum pump 6 (wide range, centred at 20 mmHg) and the container 1 is dipped in a fluid heating bath 2 previously heated.
  • the temperature of the bath 2 must be at least 30 degrees higher than the water boiling point under the used pressure conditions.
  • the fast heating and vacuum conditions involve the generation of a water vapor current in which the volatile organic components resulting from the demolition of cell structures codistill.
  • the vapors pass through the tube 3 and condense in the collector 4 maintained at low temperature by the cold bath 5.
  • the essential oil is recovered by separation from the aromatic water.
  • the obtained aromatic water is ideal for the preparation of cosmetic products and constitutes (according to the type and the state of the matrix) the 20-80 % in weight of the matrix subjected to the treatment.
  • the aromatic water and the essential oil so obtained can find application in the field of aromatherapy and food productions and aromas.
  • the duration of the separation process is short, only 15-30 minutes per 500 g of material.
  • the process can be applied to flowers, leaves, peels and every kind of vegetable material.
  • This invention has numerous advantages and will permit to overcome problems which could not be achieved by heating systems on the market today.
