Buffalo Extraction Systems

Pepper's identity splits cleanly in two. The aroma comes from its volatile essential oil, a mix of monoterpenes and sesquiterpenes like pinene, limonene and caryophyllene. The heat comes from piperine, a non-volatile alkaloid that behaves nothing like the oil around it.

That difference is where the extraction method quietly decides the outcome. Steam distillation lifts the volatile oil and leaves piperine behind, because a non-volatile alkaloid does not carry over with steam. What you get smells convincingly of pepper and has almost none of its bite. Aroma intact, pungency gone.

The complete material is the oleoresin, the volatile oil and piperine together, which is why commercial oleoresins are standardised to a defined piperine content, typically in the region of 35 to 50 percent. Supercritical CO2 reaches both, and more usefully, separates them on purpose. At lower pressure it draws off the volatile aroma oil. Raising the pressure brings piperine and the heavier resin into the extract. One tunable process, yielding the aroma fraction, the pungent oleoresin, or both in a single fractionated run, with no solvent left to remove.

Pepper is a reminder that a spice is rarely one thing. Its aroma and its heat answer to different physics, and capturing both, or either by design, comes down to control.

That control is what we build. Bring us your material and see how it fractionates.

Two facilities can run the same extraction system on the same biomass and walk away with very different results. The difference usually sits upstream, in everything that happens before extraction begins.

Sorting, drying and milling are easy to treat as preparation. In practice, they decide how much of the plant's value survives to the extractor, and how consistent every batch after it will be.

Here’s a look at what changes when pre-processing stops being separate tasks and becomes one continuous, automated line.
