Supercritical Fluid Extraction SystemAdvantages of Supercritical CO
2 Extraction over conventional:Solvent Extraction
- Solvent presence is unavoidable. The residual PPM level of the solvent depends on the type of solvent used
- Heavy metal content is also unavoidable and depends on thesolvent, the recycle method for the solvent, the source of theraw material, and the material of construction of the contact parts of the machinery
- Inorganic salt content cannot be avoided, using the same concept as above
- Polar substances get dissolved along with the lipophilic substances from the raw material due to poor selectivity of the solvent. During solvent removal operation, these polar substances formpolymers, which lead to dark color of extract and poor flow characteristics. All this renders the extract to look different fromthe basic components in the raw material and hence it is more ofa "Pseudo" natural extract
- Both polar as well as non polar colors are extracted
- Solvent removal requires extra unit operations and hence the cost and recovery of useful material is lower
- Not hygienic as protein molecules also get dissolved
SCF Extraction
- Only CO2 is used as solvent which after extraction is released and recycled hence no residual and hence totally free of solvents and product very pure
- Totally free of heavy metals since they are not extractable evenif they are present in the raw material. No heavy metals arepresent in CO2 and the equipment
- Totally free of inorganic salts using the same explanation as above no such possibility since there is very high selectivity ofco2 and no chance of polar substances forming polymers. In addition the operating temperature is only 40-50 degree celsius
- Choice of polar and non-polar components available for extraction
- No extra unit operations needed and yield of useful material is very high
- No question of biological contaminant
