5L Fully Automated Compound Remediation System
A bench-scale system that refines a finished botanical extract, selectively removing unwanted constituents at room temperature while preserving the aromatics and actives.
COMERG • Juniper extraction
Juniper Berry
Juniperus communis L.
Turn juniper berries into a fresh, food-grade extract with COMERG equipment. Our cold, room-temperature, low-pressure process captures the crisp, piney brightness of the berry, the alpha-pinene and myrcene that make juniper the defining botanical of gin, without the heat that older methods rely on.

The spice
The piney berry-cone
Juniper is the small berry-like cone of Juniperus communis, an evergreen of mountains and heaths. Its fresh, crisp, resinous aroma is mountain air in a fruit, carried by alpha-pinene and myrcene, the terpenes that also make juniper the botanical at the heart of gin.
The berries are milled and processed cold, so the finished extract keeps the full piney brightness of the fruit. Nothing is added, and the natural balance of pinene, myrcene and the supporting terpenes is preserved.

The extract
What the process delivers
Run on COMERG equipment, juniper berries yield a standardised, high-strength extract, batch after batch. Because the extraction is cold and solvent-light, with no high heat, the crisp piney notes carry straight through to the finished oil. The figures below are typical of a standardised BJun-60.1 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 juniper character.
1
Pressurised R134a flooding
Non-toxic liquefied R134a gas is introduced to the milled juniper berries 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 alpha-pinene, myrcene and the bright terpenes, while the heat-sensitive piney top 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 juniper extract, at least 60% volatile oil, with under 0.1 g/kg residue.
Aromatic profile
The compound fingerprint
Principal constituents identified by GC-MS, each above 1%. Alpha-pinene leads, with myrcene close behind, the pair that gives juniper its fresh, resinous, mountain-air character.

Why the COMERG line
Built for fresh botanicals like juniper
The crisp freshness above is not an accident of the berry alone, it is what the right equipment makes repeatable. Our line is engineered around the things that matter when you process a terpene-rich, top-note botanical.
Room temperatureR134a aerosol extraction works cold and at low pressure, so the volatile piney top notes are never cooked off.
Keeps the pineneAlpha-pinene and myrcene carry the fresh juniper character. Cold extraction concentrates them cleanly into the extract.
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 berry'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 juniper, with a clean, fresh, high-strength result.

From berry to extract
The machines for juniper
A complete COMERG line takes juniper from raw berry 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 juniper oil cold, below 25 °C, from 10 l pilot units up to 2000 l.
Room temp • 97% recoveryView system
Berry separation
Cleans and separates the berries from stalk and debris before milling, so only the aromatic berry reaches the extractor.

Questions
Juniper extraction, explained
A 100% natural juniper berry extract, product code BJun-60.1. It reaches at least 60% volatile oil, led by around 32% alpha-pinene and 21% myrcene, 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.
Juniper's freshness lives in light monoterpenes like alpha-pinene and myrcene that can be dulled by prolonged heat. Cold R134a extraction concentrates them cleanly so the extract stays crisp and piney.
Roughly 1 kg of extract represents around 60 to 75 kg of milled juniper berries.
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.
