COMERG • Ginger extraction
Dried Ginger
Zingiber officinale Roscoe
Turn ginger rhizome into a warm, food-grade extract with COMERG equipment. Our cold, room-temperature, low-pressure process captures the spicy, woody-citrus heart of the root, the zingiberene that defines ginger's aroma, along with the warming pungent fraction, all without heat.

The spice
The warm, spicy rhizome
Ginger is the rhizome of Zingiber officinale, a knobbly underground stem with a warm, woody, faintly citrus aroma and a familiar peppery heat. The scent comes mainly from zingiberene, the signature sesquiterpene of the root, while the warming pungency sits in the heavier gingerol and shogaol fraction.
The rhizome is dried, milled and processed cold, so the finished extract carries the full warmth of the spice. Ginger belongs to the same family as cardamom and turmeric, and shares their rich, aromatic character.

The extract
What the process delivers
Run on COMERG equipment, ginger rhizome yields a standardised, high-strength extract, batch after batch. Because the extraction is cold and solvent-light, with no high heat, the warm aromatic notes carry straight through to the finished oil. The figures below are typical of a standardised BGin-70.1 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 ginger character.
1
Pressurised R134a flooding
Non-toxic liquefied R134a gas is introduced to the milled ginger rhizome 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 zingiberene and the warm sesquiterpenes, while the heat-sensitive aromatic notes stay structurally intact.
3
Recovery and pure extract
The R134a is fully recovered and recycled in a closed loop. What is left is a concentrated ginger extract, at least 70% volatile oil, with under 0.1 g/kg residue.
Aromatic profile
The compound fingerprint
Principal constituents identified by GC-MS, each above 1%. Zingiberene dominates the profile, supported by a family of sesquiterpenes that together give ginger its warm, woody-spicy signature.

Why the COMERG line
Built for warm spice like ginger
The warmth above is not an accident of the root alone, it is what the right equipment makes repeatable. Our line is engineered around the things that matter when you process a high-value spice.
Room temperatureR134a aerosol extraction works cold and at low pressure, so the warm aromatic notes are never cooked off.
Keeps the zingibereneZingiberene carries almost the whole ginger aroma. Cold extraction concentrates it cleanly, alongside the warming pungent fraction.
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 root'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 ginger, with a clean, warm, high-strength result.

Questions
Ginger extraction, explained
A 100% natural ginger rhizome extract, product code BGin-70.1. It reaches at least 70% volatile oil, led by around 42% zingiberene, 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.
Ginger's aroma lives in zingiberene and a family of sesquiterpenes, while its heat comes from the gingerol fraction. Cold R134a extraction concentrates the aromatics cleanly and carries the warming compounds through, without the prolonged heat that can dull them.
Roughly 1 kg of extract represents around 30 to 40 kg of dried, milled ginger rhizome.
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.
