Extraction

Check out our extraction process from field to ingredient creation

Respect of the product

We plant and cultivate our own Manuka in our Waipu field. By arranging the trees in rows and topping them, we are able to preserve 90% of the plant for quicker regeneration.

Upon harvest, the leaves are separated from the stems and processed in our specialised equipment, which is our Supercritical extraction plant.

What is Supercritical Fluid Extraction?

An Technologically Advanced Method

This technique is gaining traction in the fragrance industry because of its effectiveness in preserving the biological properties of plants without degradation. It yields a purer plant essence.

How does it work?

The plant material is placed in a chamber where it is carefully heated to 31.1°C and pressurised to 70 Bar. Under these conditions, the CO₂ becomes "supercritical," exhibiting the characteristics of both a gas (for penetration and diffusion) and a liquid (for retention). This enables the precise capture of specific molecules. Once the actives are absorbed, the CO₂ is depressurised, losing its retention properties and allowing us to collect the actives. The gas is then recirculated for ongoing extraction, ensuring an efficient process.

Is it Safe?

The procedure is highly secure. We utilise specialised equipment that features multiple safety valves and precise measurements. Additionally, since CO₂ is non-flammable, there's no risk of it suddenly igniting.

Once the extracts are collected, any remaining CO₂ naturally evaporates, ensuring no residue remains. Rest assured, this process is both effective and safe.

Do you produce CO₂ to extract?

No we don't. We know how negative CO₂ image can be and this is a point we want to clear up.

We purchase CO₂ from gas supplier. The gas is then recycled at more than 85% with our equipment making this extraction not only economic but also Carbon Zero.
