Oak Moss
Oak Moss
Mechotech designs and manufactures turnkey wood absolute extraction plants for Oak Moss. The product tree lists the feed as moss / lichen. The Sureka Life Sciences (SLS) catalogue lists Oak Moss Extract with Evernia prunastri as the botanical source and evernic acid (catalogue grade 3%) as the marker compound, with perfumery as its primary application. The plant extracts the moss with food-grade solvent, filters and concentrates the extract with solvent recovery and standardises it to the client’s specification. The exact feed form is confirmed with the client before the plant is configured.
Mechotech’s Oak Moss plant is configured around the raw material and the target extract. Built in SS 316L with integrated solvent recovery, automation and full documentation, each plant is delivered as a commissioned turnkey system. The solvent, temperatures and cycle times are established during process development and pilot validation.

Plant Capacities
| Plant Scale | Raw Material Throughput | Typical Use |
|---|---|---|
| Pilot | Configured to your feedstock and trial plan | Product development, parameter validation |
| Semi-Commercial | Configured between pilot and commercial scale | Contract manufacturing, scale-up trials |
| Commercial | Configured to raw-material supply and confirmed buyer volume | Commercial production at confirmed buyer volume |
Capacity is configured to raw-material supply and confirmed buyer volume; we recommend a pilot plant to validate process parameters before scaling.
Manufacturing Process
Raw Material Preparation
Oak moss is authenticated, cleaned of bark, twigs and foreign matter, tested for moisture and, where required, size-reduced so that the solvent reaches the lichen material; the feed form and particle size are set during process development.
Extraction
Milled Oak Moss is extracted with food-grade solvent (alcohol / aqueous) in closed jacketed SS 316L extractors under controlled temperature and multiple cycles to maximise recovery of the target actives.
Filtration
The extract (miscella) is clarified through a plate-and-frame filter press followed by cartridge polish filters.
Concentration & Solvent Recovery
The miscella is concentrated in a falling-film / vacuum evaporator, with solvent recovered through the condenser return system.
Standardisation
The concentrate is assayed and adjusted to the client’s target specification before release.
Quality Control & Release
The standardised Oak Moss concentrate is released after assay, residual-solvent, heavy-metal, microbial and moisture testing.

Plant Output
From Plant to Product
Oak Moss Extract
This botanical is also in the product range of Sureka Life Sciences, our sister concern in botanical ingredients.
Applications
- Perfumery (primary application listed by Sureka Life Sciences)
- Cosmetics and skin-care products
Key Features
SS 316L Construction
Electropolished SS 316L product-contact surfaces with CIP operation between batches.
Closed-Loop Solvent Recovery
Integrated condenser-return recovery reuses solvent between batches and reduces solvent loss.
Standardised to Specification
In-process and batch-release assay are used to check the finished extract against the agreed target specification.
Concentrate Finishing & Quality Control
Concentration and finishing are configured for a solvent-extracted aromatic concentrate rather than a spray-dried powder, with batch-release testing and certificate-of-analysis documentation.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
