African Spinach Leaf Extract
African Spinach Leaf Extract
Extraction Technologies
Mechotech designs and manufactures turnkey extraction plants that process African spinach leaves to recover polyphenols and soluble fiber. We supply the machinery for the route selected after screening — raw-material preparation, extraction, separation, concentration or recovery, and drying or collection — configured to the target specification. Mechotech's technology screening assigns routes by target — polyphenols: Counter-Current (CCE), Ultrasound (UAE), Hybrid and Microwave (MAE); soluble fiber: Subcritical Water (SWE) and Enzyme-Assisted (EAE); the best-ranked route overall is Enzyme-Assisted Extraction (EAE) (relevant screening, rank 36 of 100).
For African spinach leaves with polyphenols and soluble fiber as the target, there are 6 candidate technologies: Counter-Current Extraction (CCE), Subcritical Water Extraction (SWE), Ultrasound-Assisted Extraction (UAE), Enzyme-Assisted Extraction (EAE), Hybrid Extraction and Microwave-Assisted Extraction (MAE). By route — Counter-Current (CCE) for polyphenols: relevant screening, rank 38 of 100, ethanol/water or suitable food-grade solvent; Subcritical Water (SWE) for soluble fiber: relevant screening, rank 44 of 100, pressurized water; Ultrasound (UAE) for polyphenols: relevant screening, rank 38 of 100, ethanol/water or water; Enzyme-Assisted (EAE) for soluble fiber: relevant screening, rank 36 of 100, water, enzyme and pH control; Hybrid for polyphenols: relevant screening, rank 40 of 100, sequence selected by target; Microwave (MAE) for polyphenols: relevant screening, rank 38 of 100, ethanol/water or water. For the best-ranked route, Enzyme-Assisted (EAE), the screening flags: select cellulase/pectinase/protease by matrix; control enzyme cost and inactivation. These are screening candidates rather than guarantees: the final technology, operating parameters and plant configuration are established during process development and pilot validation. Product-contact parts are built in SS 316L with CIP-cleanable design, and automation is configured to the project.

Manufacturing Process
Each extraction method follows a different process — pick a method to see its steps.
Raw-Material Preparation
African spinach leaves are cleaned and size-reduced so polyphenols and soluble fiber can be reached by the extraction medium; particle size and moisture are set during process development.
Counter-Current Loading
Prepared African spinach leaves 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 polyphenols and soluble fiber; bed flow and fines management are verified during pilot work.
Extract (Miscella) Collection
The polyphenols and soluble fiber-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 polyphenols and soluble fiber-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.
Fraction Recovery, Standardisation & Drying
The targets (polyphenols and soluble fiber) are recovered as fractions by a route selected during process development, checked against the target specification and dried or concentrated as required.
Raw-Material Preparation
African spinach leaves are cleaned and size-reduced so polyphenols and soluble fiber can be reached by the extraction medium; particle size and moisture are set during process development.
Vessel Loading & Pressurisation
Prepared African spinach leaves and water are loaded into a pressure-rated extraction vessel.
Subcritical Water Extraction
Water held liquid under pressure at elevated temperature extracts polyphenols and soluble fiber without an organic solvent; temperature and residence time are set to limit thermal degradation and hydrolysis.
Separation
Spent leaves 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.
Fraction Recovery, Standardisation & Drying
The targets (polyphenols and soluble fiber) are recovered as fractions by a route selected during process development, checked against the target specification and dried or concentrated as required.
Raw-Material Preparation
African spinach leaves are cleaned and size-reduced so polyphenols and soluble fiber can be reached by the extraction medium; particle size and moisture are set during process development.
Slurrying
Prepared African spinach leaves are slurried with ethanol/water or water in the extraction vessel.
Ultrasonic Cavitation
Ultrasound creates cavitation that disrupts the leaves tissue and speeds release of polyphenols and soluble fiber; probe intensity, temperature and filtration behaviour are piloted.
Separation
Spent leaves are separated by filtration or centrifugation and the extract is clarified before concentration.
Concentration & Solvent Recovery
Solvent is removed from the clarified polyphenols and soluble fiber-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.
Fraction Recovery, Standardisation & Drying
The targets (polyphenols and soluble fiber) are recovered as fractions by a route selected during process development, checked against the target specification and dried or concentrated as required.
Raw-Material Preparation
African spinach leaves are cleaned and size-reduced so polyphenols and soluble fiber can be reached by the extraction medium; particle size and moisture are set during process development.
Slurry & pH Control
Prepared African spinach leaves 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 leaves matrix) breaks down bound cell-wall material to release polyphenols and soluble fiber; 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.
Fraction Recovery, Standardisation & Drying
The targets (polyphenols and soluble fiber) are recovered as fractions by a route selected during process development, checked against the target specification and dried or concentrated as required.
Raw-Material Preparation
African spinach leaves are cleaned and size-reduced so polyphenols and soluble fiber can be reached by the extraction medium; particle size and moisture are set during process development.
Stage Sequence Selection
A deliberate combined extraction train is used: the sequence of stages is selected for polyphenols and soluble fiber in pilot screening and each stage is designed separately.
First Assisted Stage
The first stage releases polyphenols and soluble fiber from the leaves under controlled conditions set for that stage.
Second / Combined Stage
The second stage completes recovery of polyphenols and soluble fiber from the partially extracted material; stage conditions are optimised separately.
Separation & Concentration
Spent solids are removed and the combined extract is clarified and concentrated; solvent is recovered where a solvent is used.
Fraction Recovery, Standardisation & Drying
The targets (polyphenols and soluble fiber) are recovered as fractions by a route selected during process development, checked against the target specification and dried or concentrated as required.
Raw-Material Preparation
African spinach leaves are cleaned and size-reduced so polyphenols and soluble fiber can be reached by the extraction medium; particle size and moisture are set during process development.
Medium Mixing
Prepared African spinach leaves are mixed with ethanol/water or water in the microwave extraction vessel.
Microwave Heating & Extraction
Controlled microwave heating drives polyphenols and soluble fiber out of the leaves 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 leaves are separated by filtration or centrifugation and the extract is clarified before concentration.
Concentration & Solvent Recovery
Solvent is removed from the clarified polyphenols and soluble fiber-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.
Fraction Recovery, Standardisation & Drying
The targets (polyphenols and soluble fiber) are recovered as fractions by a route selected during process development, checked against the target specification and dried or concentrated as required.

Key Features
Enzyme-Assisted (EAE) — Relevant Screening Fit
Best-ranked route for African spinach leaves: rank 36 of 100 in Mechotech's enzyme-assisted extraction screening, using water, enzyme and pH control. Ranks are directional screening priorities, not measured yield, ROI or plant guarantees.
African spinach leaves — 6 Candidate Routes
Routes screened for African spinach leaves: Counter-Current (CCE) — relevant, rank 38; Subcritical Water (SWE) — relevant, rank 44; Ultrasound (UAE) — relevant, rank 38; Enzyme-Assisted (EAE) — relevant, rank 36; Hybrid — relevant, rank 40; Microwave (MAE) — relevant, rank 38. Each route has its own process tab above.
2-Target Scope
Targets are assigned to routes in the screening — polyphenols: Counter-Current (CCE), Ultrasound (UAE), Hybrid and Microwave (MAE); soluble fiber: Subcritical Water (SWE) and Enzyme-Assisted (EAE) — so each route’s steps name only the target it is screened for.
Parameters Fixed After Pilot Trials
Recovery of polyphenols and soluble fiber, selectivity, solvent or water duty, quality and cleaning are measured in pilot trials, starting with small-scale feed trials, before final plant parameters are fixed.
SS 316L Hygienic Construction
Product-contact surfaces are SS 316L and CIP-cleanable, in a hygienic design suited to food, nutraceutical and pharmaceutical supply chains; PLC-SCADA automation with recipe control can be configured to the project scope.
