COMERG • Black pepper extraction
Black Pepper
Piper nigrum L.
Turn peppercorns into a high-strength, food-grade extract with COMERG equipment. Our cold, room-temperature, low-pressure process captures the bright, woody, citrus-fresh aroma of black pepper, the delta-3-carene and caryophyllene that define the spice, with no heat to flatten the top notes.

The spice
The king of spices
Black pepper, Piper nigrum, is the most traded spice on earth, and its warmth is unmistakable. The aroma is bright and woody with a citrus lift, carried by delta-3-carene, caryophyllene and limonene, while the pungent bite that pepper is loved for comes from its piperine.
The dried peppercorns are milled and processed cold, so the finished extract keeps the fresh, lively top of the spice rather than the dull, flat note that heat can leave behind. Nothing is added, and the full aromatic balance is preserved.

The extract
What the process delivers
Run on COMERG equipment, peppercorns yield a standardised, high-strength extract, batch after batch. Because the extraction is cold and solvent-light, with no high heat, the bright woody aroma carries straight through to the finished oil. The figures below are typical of a standardised BBPe-50.1 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 pepper character.
1
Pressurised R134a flooding
Non-toxic liquefied R134a gas is introduced to the milled peppercorns 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 delta-3-carene, caryophyllene, limonene and the pungent resin, while the fresh, volatile 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 pepper extract, at least 50% volatile oil, with under 0.1 g/kg residue.
Aromatic profile
The compound fingerprint
Principal constituents identified by GC-MS, each above 1%. Delta-3-carene leads, with caryophyllene and limonene close behind, the trio that gives black pepper its bright, woody, citrus-edged warmth.

Why the COMERG line
Built for bold spices like pepper
The bright, lively warmth above is what the right equipment makes repeatable. Our line is engineered around the things that matter when you process a high-oil, top-note spice.
Room temperatureR134a aerosol extraction works cold and at low pressure, so the volatile, citrus-fresh top notes are never cooked off.
Keeps the biteBoth the bright aromatic terpenes and the pungent resin come through, so the extract carries pepper's full warmth and kick.
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 pepper, with a bright, high-strength result.

Questions
Black pepper extraction, explained
A 100% natural black pepper extract from Piper nigrum, product code BBPe-50.1. It reaches at least 50% volatile oil, led by around 23% delta-3-carene, 20% caryophyllene and 17% limonene, 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.
Pepper's freshness lives in light terpenes like delta-3-carene and limonene that prolonged heat can flatten. Cold R134a extraction concentrates them cleanly, and it carries the pungent resin too, so the extract stays bright and full.
Roughly 1 kg of extract represents around 25 to 32 kg of dried peppercorns.
Yes. It is produced with a food-grade solvent per Directive 97/60/EC. Typical filling rates are 10 to 150 mg per kilogram of food product. It is a raw material for formulation, not for direct or undiluted 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.
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.
