The mango and (rum) muscovado flavours blended very well together. The finished product was delicious, I could not keep my spoon out of the mixture. I began to cycle the soxhlet.Ī good visual indication to show when it is almost finished is the mango or sample looses it’s colour and looks bleached out.

Into the soxhlet thimble I placed shredded dried mango. One example of a concoction that I recently made, was to put 500ml of a golden syrup /Dk muscovado sugar (rum type) spirit into the boiling flask of approx’ 45% abv. An interesting point, the 40% abv in the flask raises to approx' 80% abv at 22 deg C when condensed in the thimble chamber. The cycle is repeated, clear ethanol again condenses onto the botanicals / semi solids as many times as required to extract from the botanicals. When the thimble fills up the ethanol syphons back into the flask. The ethanlol reaches it’s evaporating point and drops from the condenser into the thimble wetting the botanical. Above the flask is a glass tube which within is placed a glass thimble to hold your botanical samples, above this is a water cooled condenser. An example would be to put 700ml of ethanol, around 40% abv in a small glass boiling flask. Using a Soxhlet is to use an appropriate solvent to extract the essence / flavour from a semi solid. Maybe pull flavour from oak chips to artificially age spirit ? I was wondering how many members use a Soxhlet or are interested in using one to extract flavour / essential oils from semi-solids, dried fruits & botanicals, to add to neutral spirit.

Finally, the heating is stopped and the solution in the flask is distilled to recover the solvent, While the organic compound is left behind. In this way, a continuous supply of solvent vapors is maintained in the cylinder, and the dissolved organic compound flows back into the flask. As soon as the solution reaches the top end of the siphon tube. The condensed solvent comes in contact with the crude organic substance and dissolves it. The solvent vapors reach the cylinder through the inlet tube and conduce on passing upward into the condenser. The flask is heated in a water bath or sand bath. This entire assembly is fitted into the neck of a round bottom flask containing the solvent. A water condenser is attached to the cylinder at the top. This cylinder is provided with a siphon tube and an inlet tube. The crude substance is placed in a thimble-shaped filter paper which is then kept in a glass cylinder. The flask is repeated, extracting a portion of the material each time so that the solid material is constantly used as a pure solvent and the extracted material is concentrated in the flask. The solvent is added to the solvent reservoir flask and mounted onto a heating mantle. After heating, the condensed vapors of the solvent come in contact with the sample powder, and the soluble part of the powder gets mixed with the solvent for extraction. When the solvent surface exceeds the maximum height of the siphon, the solvent containing the extract is siphoned back. The Soxhlet extraction uses the solvent reflux and siphon principle to continuously extract the solid matter by pure solvent, which saves the solvent extraction efficiency and high efficiency. The sold sample is placed on a thimble-shaped filter paper, positioned into the Soxhlet extractor, and the device is assembled. The Soxhlet extraction method uses a small amount of solvent and is very cost-effective. This is a very useful technique for preparative goals in which the analyte is concentrated from the matrix as a whole or separated from specific interfering substances. In 1879, Franz Ritter von Soxhlet, professor of agricultural chemistry at the Technical University of Munich, developed this extraction technique. Soxhlet extraction is an advanced extraction technique that involves repeatedly circulating the same solvent through the extractor.
