Process Description
Raw Material Preparation
Fenugreek seeds are cleaned, graded, and milled to a controlled particle size for efficient extraction and improved solvent penetration.
Hydro-Alcoholic Extraction
Prepared fenugreek seed powder is extracted under optimised temperature, pressure, and solvent conditions to recover steroidal saponins and other bioactive compounds.
The extraction system provides:
- High saponin recovery
- Uniform extraction efficiency
- Consistent batch quality
- Reduced processing time
Filtration
The crude extract passes through pressure leaf filters to remove suspended solids and prepare the extract for purification.
Vacuum Solvent Recovery
The filtered extract enters vacuum evaporators where extraction solvent is recovered, condensed, purified, and recycled.
Benefits include:
- Reduced solvent cost
- Improved plant safety
- Environmental sustainability
- Higher product purity
Vacuum Concentration
The extract is concentrated under vacuum at controlled temperatures to preserve heat-sensitive phytochemicals.
Membrane Purification
Microfiltration and ultrafiltration systems improve extract clarity while enriching active compounds.
Advantages include:
- Improved purity
- Better stability
- Lower product losses
Resin Enrichment
Specialised adsorption resin columns selectively enrich saponins and 4-Hydroxyisoleucine while removing unwanted compounds.
This stage provides:
- Higher active content
- Better product appearance
- Improved batch consistency
- Pharmaceutical-grade quality
Spray Drying
The purified extract is spray dried into a free-flowing powder with excellent flowability and shelf stability.
Quality Standardisation
Each production batch is analysed for:
- Total Saponins
- Diosgenin
- 4-Hydroxyisoleucine
- Galactomannan
- Trigonelline
- Moisture
- Residual Solvent
- Heavy Metals
- Pesticide Residues
- Microbial Limits
- Particle Size
