COMERG • Parsley extraction
Garden Parsley
Petroselinum crispum (Mill.) Fuss
Turn fresh parsley leaf into a bright, green, true-to-herb extract with COMERG equipment. Our cold, room-temperature, low-pressure process captures the lively, green parsley note, the p-mentha-1,3,8-triene and phellandrene that define it, with no heat to flatten the fresh top.

The herb
The Mediterranean's everyday green
Parsley, Petroselinum crispum, is the most used culinary herb around the Mediterranean, and its scent is unmistakably fresh and green. That character comes from p-mentha-1,3,8-triene and beta-phellandrene, lifted by linalool and limonene, with apiole and myristicin, the phenylpropanoids typical of parsley, giving a warm, spicy depth underneath.
We work with the fresh leaf, cut through the summer and processed cold so the bright, herbaceous top survives. Nothing is added, and the lively green character of the herb is carried straight into the extract.

The extract
What the process delivers
Run on COMERG equipment, parsley leaf yields a standardised, true-to-herb extract, batch after batch. Because the extraction is cold and solvent-light, with no high heat, the fresh green character carries straight through to the finished oil. The figures below are typical of a standardised BPar-40.1 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 fresh, green character of parsley leaf.
1
Pressurised R134a flooding
Non-toxic liquefied R134a gas is introduced to the fresh parsley leaf 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 p-mentha-1,3,8-triene, the phellandrene, linalool and the phenylpropanoids, while the fresh, volatile green 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 parsley extract, at least 40% volatile oil, with under 0.1 g/kg residue.
Aromatic profile
The compound fingerprint
Principal constituents identified by GC-MS, each above 1%. p-Mentha-1,3,8-triene leads, the green heart of parsley, with phellandrene, linalool and limonene, while apiole and myristicin give the warm, spicy depth.
0%10%16%21%+
The green note sits in p-mentha-1,3,8-triene, phellandrene and limonene; apiole and myristicin are the characteristic parsley phenylpropanoids and the reason the concentrated extract is used at low levels. Other extractables present. Per-batch GC-MS report available on request.

Green fragrance notes
Parsley extract naturally contains apiole and myristicin, so the concentrated extract is used at low, culinary levels and is not recommended for use in pregnancy at high doses. It is also classed as a dangerous good for transport (flammable liquid). Like all our extracts it is a raw material for formulation. Keep away from children.
This parsley extract is edible and can be used concentrated or diluted in a carrier oil to suit the application. Typical filling rates for the concentrated extract in food are 5 to 250 mg per kilogram of product.
Why the COMERG line
Built for fresh herbs like parsley
The bright, lively green above is what the right equipment makes repeatable. Our line is engineered around the things that matter when you process a delicate, high-water leafy herb.
Room temperatureR134a aerosol extraction works cold and at low pressure, so the fresh, volatile green top notes are never cooked off.
Keeps it greenThe p-mentha-triene and phellandrene that carry parsley's fresh note come through cleanly, not flattened by heat.
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 leaf'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 parsley, with a fresh, true-to-leaf result.

Questions
Parsley extraction, explained
A 100% natural parsley leaf extract from Petroselinum crispum, product code BPar-40.1. It reaches at least 40% volatile oil, led by around 21% p-mentha-1,3,8-triene with phellandrene, linalool and the parsley phenylpropanoids, and 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.
Parsley's freshness lives in light terpenes like p-mentha-1,3,8-triene that prolonged heat can flatten. Cold R134a extraction concentrates them cleanly, so the extract keeps its bright, true-to-leaf green character.
Roughly 1 kg of extract represents around 250 to 300 kg of fresh parsley leaf.
Yes, it is edible, with typical filling rates of 5 to 250 mg per kilogram of product. Because it contains apiole and myristicin it is used at low, culinary levels, and the concentrated extract is classed as a dangerous good for transport, so it ships under the appropriate dangerous-goods rules.
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.
