EXTRACTION OF ESSENTIAL OILS/NATURAL EXTRACTS OIL
(CODE NO. 1958)


Importance of using super critical fluid in extraction of essential oils from flower, herbs and spices.
     
In modern times interest is growing in solvents that are high pressure  intermediate density super critical  fluids. The solvent power of such fluids can be  changed by varying the density and less energy is required to  separate  solute  from solvent than with conventional vaporization of liquids.

Super critical fluid extraction is a hybrid unit operation utilizing the advantages  of  both distillation and liquid extraction. It has the benefit that slight changes is the temperature and pressure in the critical region cause extremely large changes  is the solvent density and thus its dissolving power.

In comparison with conventional processes, SCF (Super Critical Fluid Extraction) offers considerable flexibility for an extractive  flexibility  for an extractive separation  using  the variables  of  pressure,  temperature  choice  of solvent, and additives called  entertainers.

Heavy non-volatile substances dissolve in supercritical fluids (dense gases, compressed  gases, super critical gases, high pressure gases), typically 2-7  orders of magnitude is excess of the amount based on the ideal gas  low. This is due to the high density of the fluid, which can approach that of a liquid. Thus SCF offers both high solubility extraction based  on the enhancement of vapour pressure and heavily complete solvent extract separation which is accomplished by reducing the solvent density to the gaseous state.

Essential  oil  also  called etheral or  volatile  oils  are volatile  odoriferous bodies of an oily character derived  mostly form  vegetable  sources. They occur in small concentrations in special cells, glands or ducts, either in one particular organ of the plant or distributed over many part e.g.  leaves,  barks, roots,  flowers  or  fruits. Occasionally, they are present in combination with sugars, as glycosides, e.g. amyodalin in bitter almonds and sinigrin in mustard seeds, and are liberated when the glycosides are hydrolyzed. Essential oils are insoluble in water, but freely soluble in alcohol, either, fatty oils and mineral oils.
