Fenugreek Extract (Saponins)
Fenugreek Extract (Saponins)
Purity Levels
40% Lucin Saponins by Gravimetry
Extraction Technologies
Mechotech designs and manufactures turnkey Fenugreek (Trigonella foenum-graecum) extraction plants that convert cleaned, milled fenugreek seed into a standardised extract of 40% Lucin Saponins by Gravimetry. We supply the complete line — seed cleaning, milling, hydro-alcoholic extraction, filtration, solvent recovery, vacuum concentration, standardisation and drying — as a single turnkey system for the pharmaceutical, nutraceutical, food, and fragrance industries. Candidate extraction technologies for saponins, fenugreek oleoresin and galactomannan: Counter-Current Extraction (CCE), Supercritical CO₂ Extraction (SCFE), Subcritical Water Extraction (SWE), Ultrasound-Assisted Extraction (UAE), Enzyme-Assisted Extraction (EAE) and Microwave-Assisted Extraction (MAE) (6 in total).
Mechotech's Fenugreek Extract plant is engineered around the real processing chemistry of fenugreek seed, which yields steroidal saponins (diosgenin precursors), 4-hydroxyisoleucine and galactomannan fibre alongside trigonelline and flavonoids. Hydro-alcoholic extraction in closed jacketed SS 316L vessels recovers the saponin fraction, and the concentrate is assayed and standardised to the declared 40% Lucin Saponins by Gravimetry specification before drying. Built with integrated solvent recovery, automation, and full documentation, each plant is delivered as a commissioned turnkey system to GMP and HACCP standards.

Manufacturing Process
Each extraction method follows a different process — pick a method to see its steps.
Raw-Material Preparation
Fenugreek seeds are cleaned and size-reduced so saponins can be reached by the extraction medium; particle size and moisture are set during process development.
Counter-Current Loading
Prepared fenugreek seeds are fed into a multi-stage solid–liquid counter-current extractor where fresh ethanol/water or a suitable food-grade solvent meets the most-depleted material.
Counter-Current Extraction
Solvent flows against the solids across stages to draw out saponins; bed flow and fines management are verified during pilot work.
Extract (Miscella) Collection
The saponins-bearing miscella is collected from the fresh-feed end while spent solids are discharged from the solvent-entry end.
Concentration & Solvent Recovery
Solvent is removed from the clarified saponins-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.
Standardisation & Drying
The saponins extract is assayed against the declared target specification and dried or supplied as a concentrate, according to the requirement.
Raw-Material Conditioning
Fenugreek seeds are cleaned and conditioned so fenugreek oleoresin is accessible to supercritical CO₂; moisture and particle size are set during process development.
Extraction Vessel Loading
Conditioned fenugreek seeds are charged into the high-pressure extraction vessel.
Supercritical CO₂ Extraction
Supercritical CO₂ passes through the charge and dissolves fenugreek oleoresin; an ethanol modifier can be evaluated where polar fractions are also required, and operating pressure and temperature are set in process development.
Separator Collection
Pressure is reduced in separator stages so the extracted fenugreek oleoresin drops out of the CO₂ and is collected.
CO₂ Recycle
Gaseous CO₂ is re-liquefied and recirculated to the extractor, limiting make-up gas demand.
Finishing & Packing
The collected fenugreek oleoresin is polished by filtration as needed and packed to the required specification.
Raw-Material Preparation
Fenugreek seeds are cleaned and size-reduced so galactomannan can be reached by the extraction medium; particle size and moisture are set during process development.
Vessel Loading & Pressurisation
Prepared fenugreek seeds and water are loaded into a pressure-rated extraction vessel.
Subcritical Water Extraction
Water held liquid under pressure at elevated temperature extracts galactomannan without an organic solvent; temperature and residence time are set to limit thermal degradation and hydrolysis.
Separation
Spent solids are separated by filtration or centrifugation and the extract is clarified before concentration.
Concentration
The clarified aqueous extract is concentrated under vacuum or by membrane systems where required; no organic solvent is used in this route.
Recovery, Standardisation & Drying
The galactomannan fraction is recovered from the concentrate by a route selected during process development and checked against the target specification; drying behaviour is verified because polysaccharide-type targets can be heat-sensitive.
Raw-Material Preparation
Fenugreek seeds are cleaned and size-reduced so saponins can be reached by the extraction medium; particle size and moisture are set during process development.
Slurrying
Prepared fenugreek seeds are slurried with ethanol/water or water in the extraction vessel.
Ultrasonic Cavitation
Ultrasound creates cavitation that disrupts the plant matrix and speeds release of saponins; probe intensity, temperature and filtration behaviour are piloted.
Separation
Spent solids are separated by filtration or centrifugation and the extract is clarified before concentration.
Concentration & Solvent Recovery
Solvent is removed from the clarified saponins-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.
Standardisation & Drying
The saponins extract is assayed against the declared target specification and dried or supplied as a concentrate, according to the requirement.
Raw-Material Preparation
Fenugreek seeds are cleaned and size-reduced so galactomannan can be reached by the extraction medium; particle size and moisture are set during process development.
Slurry & pH Control
Prepared fenugreek seeds are slurried in water with pH and temperature set for the enzyme system.
Enzymatic Treatment
An enzyme (for example a cellulase, pectinase or protease, selected for the fenugreek seeds matrix) breaks down bound cell-wall material to release galactomannan; enzyme cost and specificity are validated at pilot scale.
Enzyme Inactivation & Separation
The enzyme is inactivated and spent solids are separated by filtration or centrifugation.
Concentration
The clarified aqueous extract is concentrated under vacuum or by membrane systems where required; no organic solvent is used in this route.
Recovery, Standardisation & Drying
The galactomannan fraction is recovered from the concentrate by a route selected during process development and checked against the target specification; drying behaviour is verified because polysaccharide-type targets can be heat-sensitive.
Raw-Material Preparation
Fenugreek seeds are cleaned and size-reduced so saponins can be reached by the extraction medium; particle size and moisture are set during process development.
Medium Mixing
Prepared fenugreek seeds are mixed with ethanol/water or water in the microwave extraction vessel.
Microwave Heating & Extraction
Controlled microwave heating drives saponins out of the prepared feed in a short cycle; heating, moisture, solvent safety and temperature-sensitive targets are controlled, with limits set during process development and pilot validation.
Separation
Spent solids are separated by filtration or centrifugation and the extract is clarified before concentration.
Concentration & Solvent Recovery
Solvent is removed from the clarified saponins-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.
Standardisation & Drying
The saponins extract is assayed against the declared target specification and dried or supplied as a concentrate, according to the requirement.
