SCFE : Super Critical Fluid Extraction
SCFE : Super Critical Fluid Extraction
SCFE ensures impurity free products. The extracts
derived are pure and free of any residual solvents. Besides, the extracts
contain no heavy metals or pesticides and they are free from microbial
contamination.
CO2 technology allows selective isolation of the individual
constituents.This results in an improved quality product. The consumption of
our CO2 extract as compared to products from traditional solvent extraction
or steam distillation can be lower by 15-25%. Since the CO2 process is
carried out in an inert atmosphere, the shelf-life of the extract and,
therefore, the final product is enhanced considerably. The CO2-process takes
place at relatively low temperatures which makes it suitable for the
isolation of temperature sensitive compounds.
We supply essential oils and oleoresins from a variety of natural sources.
Among them are also a range of non-GMO and organic grown raw materials. An
added incentive is our competitive pricing which is only marginally higher
than conventional solvent extraction / steam distillation while getting a
far superior product. Quality, competitive prices and timely delivery are
some of our beliefs and ways of conducting business.
Process
A brief outline of the process is given below
Dry spices/Herbs are cleaned of the adhered impurities and other foreign
material and powdered. The powder is charged to the pre-heated extraction
vessel and the vessel is pressurized with CO2 from the storage tank. The CO2
is passed through the extraction vessel resulting in the extraction of
target products (e.g. Oleoresin/Essential Oils). By depressurization of this
mixture into a separator vessel, gaseous CO2 is recovered, recycled, and fed
back to the storage tank.
The liquid or solid product is collected at the bottom of a separator
vessel and is withdrawn. Due to the earlier evaporation of the CO2, this
product is solvent-free. It is checked for quality, standardized to our
customer requirements and/or packed and labeled directly.
Technology
The conventional distillation/solvent extraction
process being largely used currently is not an environment friendly process
and has inherent disadvantages like thermal degradation, hydrolysis, heavy
metals, pesticides and traces of unacceptable residual solvents. The SCFE
process overcomes these drawbacks.
Advantages - Process
- CO2 is a colorless, tasteless, odorless, and non toxic GRAS solvent
- Low temperature process - does not effect heat sensitive ingredients
- Process in non-oxidative CO2 atmosphere
- Longer shelf life for end products
Advantages - Products
- No residual solvents
- No heavy metals
- No microbial contamination
- Higher concentrated and lesser consumption by 15-25%
Quality
We believe that quality is not just a production
process but a belief and a way of life which is incorporated in all aspects
of our company and our employees. The QC laboratory is equipped with
sophisticated analytical instrumentation for the chemical and physical
parameter evaluation of raw materials and products.
High Performance Liquid Chromatographs (HPLC) is used to check the purity
and content of non-volatile organic compounds and a Gas Chromatograph (GC)
is used to analyze volatile organic compounds. Instrumentation for routine
quality checks such as appearance, moisture content, pH, physical properties
and consistency are also used.
