COMERG • Cardamom extraction
Green Cardamom
Elettaria cardamomum
Turn cardamom seed into a high-strength, food-grade extract with COMERG equipment. Our cold, room-temperature, low-pressure process captures the sweet, resinous warmth of true cardamom, the bright terpinyl acetate and eucalyptol top notes that heat would otherwise carry away.

The spice
The queen of spices
Cardamom is one of the most valuable spices in the world, a seed pod with a complex, warm-sweet aroma that sits somewhere between eucalyptus, citrus and resin. Its scent is led by terpinyl acetate and 1,8-cineole, bright and cooling at the top, deep and balsamic underneath.
The seeds are milled and processed cold, so the finished extract carries the full character of the pod. Nothing is added, and the natural balance of esters and oxides found in the seed is preserved.

The extract
What the process delivers
Run on COMERG equipment, cardamom seed yields a standardised, high-strength extract, batch after batch. Because the extraction is cold and solvent-light, with no high heat, the bright top notes carry straight through to the finished oil. The figures below are typical of a standardised BCar-85.1 grade.

The method
Cold extraction, in three steps
No heat, no leftover solvent. This is what happens inside a COMERG aerosol system, and why the extract keeps the full cardamom character.
1
Pressurised R134a flooding
Non-toxic liquefied R134a gas is introduced to the milled cardamom seed at controlled, low pressure. There is no heat, the cycle begins and stays at room temperature.
2
Selective aromatic dissolution
The liquid gas gently dissolves the terpinyl acetate, eucalyptol and other volatiles, while the heat-sensitive esters that give cardamom its sweetness stay intact.
3
Recovery and pure extract
The R134a is fully recovered and recycled in a closed loop. What is left is a concentrated cardamom extract, at least 85% volatile oil, with under 0.1 g/kg residue.
Aromatic profile
The compound fingerprint
Principal constituents identified by GC-MS, each above 1%. Terpinyl acetate and 1,8-cineole lead the profile and together define the sweet, cooling signature of true cardamom.

Why the COMERG line
Built for high-value spice like cardamom
The strength and character above are not an accident of the seed alone, they are what the right equipment makes repeatable. Our line is engineered around the things that matter when you process an expensive aromatic.
Room temperatureR134a aerosol extraction works cold and at low pressure, so the bright eucalyptol top notes are never cooked off.
Keeps the sweetnessThe terpinyl acetate and linalyl acetate that make cardamom sweet are delicate esters. Cold extraction keeps them where heat would hydrolyse them.
Fully automatedClosed-loop systems run the cycle for you, so results stay consistent and one operator can handle the line.
Fast cycles, high yieldLow-pressure extraction is quick and recovers up to 97% of the seed's compounds, more than older high-pressure CO2 lines.
Scales with youFrom a 10 l pilot unit to 2000 l production, the same method grows from R&D batches to full output.
Clean and economicalIt uses around 85% less energy than solvent methods and needs no special hazardous-location facility.
Why it wins
Compared to the alternatives
Against steam distillation, solvent and CO2, cold R134a extraction keeps more of the cardamom, above all the delicate esters that heat breaks apart.

From seed to extract
The machines for cardamom
A complete COMERG line takes cardamom from raw seed to a finished extract. These are the core stages, each available as standalone equipment.
Aerosol extraction
The heart of the line. Liquefied-gas systems that pull cardamom oil cold, below 25 °C, from 10 l pilot units up to 2000 l.

Questions
Cardamom extraction, explained
A 100% natural cardamom seed extract, product code BCar-85.1. It reaches at least 85% volatile oil, led by around 37% terpinyl acetate and 30% eucalyptol (1,8-cineole), with no additives.
Liquefied food-grade gas extraction at room temperature, below 25 °C, and low pressure. Because there is no high heat, the delicate aromatic compounds are preserved and solvent residue stays below 0.1 g/kg.
The esters that give cardamom its sweetness, mainly terpinyl acetate and linalyl acetate, can break down under the heat of steam distillation. Cold R134a extraction keeps them, so the extract tastes and smells closer to the fresh seed.
Roughly 1 kg of extract represents around 30 to 35 kg of dried, milled seed, which is part of why a high-strength extract is so economical to ship and use.
Yes. The same cold process runs from a 10 l pilot unit to 2000 l production systems, so you can start small and grow without changing method.
It is produced with a food-grade solvent per Directive 97/60/EC. It is a raw material for formulation, not intended for direct consumption or undiluted topical use, and users are responsible for compliance with applicable legislation.
Yes. A per-batch GC-MS analysis is available on request, and a Safety Data Sheet per 2006/1907/EC is supplied with the product.
