Cardamom Extraction Plant
Cardamom Extraction Plant
Cardamom (Elettaria cardamomum) oleoresin and essential oil are premium flavouring and therapeutic ingredients rich in 1,8-cineole, terpinyl acetate, and linalool. Mechotech builds dedicated cardamom extraction plants for food flavour manufacturers, fragrance houses, and pharmaceutical companies seeking consistent, high-quality cardamom derivatives.
Mechotech's cardamom extraction plant employs solvent extraction of decorticated cardamom seeds to yield oleoresin standardized to 60%–75% volatile oil content by GC. The plant integrates solvent recovery, vacuum evaporation, and multi-stage filtration to deliver food-grade oleoresin with authentic cardamom flavour profile and no residual solvent issues.
Manufacturing Process
Seed Separation
Cardamom pods are decorticiated using a dehusking machine to isolate seeds. Seeds are dried to below 10% moisture and ground to 20–40 mesh.
Solvent Extraction
Ground seeds are extracted with food-grade acetone or ethanol in percolation extractors. Multiple extraction cycles ensure complete oleoresin recovery from the seed matrix.
Filtration
The seed extract (miscella) is filtered through sparkler and polishing filters to remove all suspended matter before evaporation.
Solvent Evaporation
The filtered miscella is evaporated under vacuum at 50–60°C in a falling-film evaporator to yield a concentrated, pale-yellow viscous oleoresin.
Standardization
Oleoresin is tested by GC for volatile oil content (targeting 60%–75%) and terpinyl acetate content. Batches are blended to ensure specification compliance.
Packing
The standardized oleoresin is packed in lacquer-lined food-grade tins or aluminium containers under nitrogen flush to prevent oxidative degradation during storage.
Applications
- Food flavouring (confectionery, bakery, beverages)
- Beverage flavouring (tea, coffee, chai masala)
- Pharmaceutical digestive aid formulations
- Oral care and breath freshening products
- Fragrance and perfumery (oriental notes)
- Ayurvedic tonic and cardioprotective preparations
- Tobacco and betel nut flavouring
- Cosmetic and personal care applications
Key Features
Full Flavour Profile
Solvent extraction captures both volatile and non-volatile cardamom flavour compounds, delivering a more complete and authentic flavour versus essential oil alone.
High Volatile Oil Content
Optimized extraction and low-temperature evaporation preserves volatile compounds, consistently delivering 60%–75% volatile oil in the oleoresin.
Acetone & Ethanol Compatibility
Plant design supports both acetone (higher yield) and ethanol (food-grade preferred) solvent extraction with quick changeover between solvents.
Solvent Recovery System
Integrated condensation and recovery unit recycles over 95% of extraction solvent, significantly reducing per-unit processing costs.
Nitrogen Packaging
Integrated nitrogen blanketing and flush system during filling extends oleoresin shelf life and prevents off-flavour development from oxidation.
