Mechotech designs and manufactures turnkey spices oleoresin extraction plants for Coriander (Coriandrum sativum), processing dried, cleaned coriander seed into a solvent-extracted oleoresin standardised to its dominant terpene alcohol, linalool — also known in the flavour and fragrance trade as coriandrol — quantified by gas chromatography. Linalool typically accounts for the majority of coriander seed's volatile-oil fraction and is the compound that most closely tracks the seed's characteristic sweet, citrus-floral note, making GC-verified linalool content the standard commercial marker for coriander oleoresin quality. We supply the complete machinery — seed cleaning, milling, solvent extraction, filtration, vacuum concentration, closed-loop solvent recovery, and GC-based standardisation — to convert coriander seed into a consistent oleoresin for the food, flavour, fragrance, nutraceutical, and pharmaceutical industries. Candidate extraction technologies for phenolics and linalool-rich oil: Counter-Current Extraction (CCE), Supercritical CO₂ Extraction (SCFE), Ultrasound-Assisted Extraction (UAE), Hybrid Extraction and Microwave-Assisted Extraction (MAE) (5 in total).

Mechotech's Coriander oleoresin plant is engineered around the chemistry of coriander seed's volatile-oil fraction, in which linalool (coriandrol) is the principal terpene alcohol and the compound buyers assay to define oleoresin quality. Because linalool and its co-occurring terpenes are volatile and moderately heat-sensitive, the line runs controlled-temperature extraction and low-temperature vacuum concentration to limit evaporative loss and oxidative drift of the linalool content. This line is positioned around the oleoresin (solvent-extraction) product route standardised by GC assay — distinct from Mechotech's separate steam-distillation coriander-oil line and its separate supercritical-CO2 coriander-oil line, which target essential oil rather than a solvent-extracted oleoresin. Built in SS 316L with electropolished product-contact surfaces, PLC-SCADA automation and full batch documentation, each plant is delivered as a commissioned turnkey system configured to the declared Linalool (Coriandrol) by GC specification.

Manufacturing Process

Each extraction method follows a different process — pick a method to see its steps.

Raw-Material Preparation

Coriander seeds are cleaned and size-reduced so phenolics can be reached by the extraction medium; particle size and moisture are set during process development.

Counter-Current Loading

Prepared coriander seeds are fed into a multi-stage solid–liquid counter-current extractor where fresh ethanol/water or a suitable food-grade solvent meets the most-depleted material.

Counter-Current Extraction

Solvent flows against the solids across stages to draw out phenolics; bed flow and fines management are verified during pilot work.

Extract (Miscella) Collection

The phenolics-bearing miscella is collected from the fresh-feed end while spent solids are discharged from the solvent-entry end.

Concentration & Solvent Recovery

Solvent is removed from the clarified phenolics-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.

Standardisation & Drying

The phenolics extract is assayed against the declared target specification and dried or supplied as a concentrate, according to the requirement.

Frequently Asked Questions

Does Mechotech supply the complete machinery for Coriander oleoresin?

Yes. Mechotech is a coriander oleoresin extraction plant manufacturer and equipment supplier, engineering and fabricating the complete turnkey plant at our Hyderabad facility, installing and commissioning it as a single integrated system.

Why is linalool the standardisation marker for coriander oleoresin?

Linalool — also called coriandrol in the flavour and fragrance trade — is the dominant terpene alcohol in coriander seed's volatile-oil fraction and the compound most closely associated with the seed's characteristic sweet, citrus-floral note. Gas chromatography assay of linalool content is the standard commercial method for grading coriander oleoresin, which is why this plant's standardisation stage is built around GC assay rather than a generic total-oil figure.

How is this Coriander oleoresin plant different from Mechotech's Coriander distillation and CO2 lines?

This page covers the solvent-extraction oleoresin route, standardised to Linalool (Coriandrol) by GC. Mechotech separately builds a steam/hydro-distillation coriander line producing coriander essential oil, and a supercritical-CO2 coriander seed oil line producing a solvent-free CO2 extract. All three target coriander seed but use different unit operations and yield different product forms — oleoresin, distilled essential oil, and CO2 extract — so the right line depends on which product form your buyer specification requires.

Why does concentration run at low temperature for this product?

Linalool and coriander seed's co-occurring terpenes are volatile and moderately heat-sensitive. Running the vacuum evaporator at controlled, low temperature limits evaporative loss and oxidative drift of the linalool fraction during concentration, protecting the finished oleoresin's GC assay.

What raw material and plant part is used for coriander oleoresin?

Dried, cleaned coriander seed (the fruit of Coriandrum sativum) is used. The volatile-oil fraction responsible for the oleoresin's linalool content is concentrated within the seed's oil-bearing tissue, which is why controlled cracking/milling ahead of extraction is an important process step.

What production capacities are available for the Coriander oleoresin plant?

Capacity is selected from raw-material supply, confirmed buyer volume and investment timeline; Mechotech recommends a pilot plant to validate process parameters before scaling.

Which industries buy Coriander oleoresin, and does the plant support GMP qualification?

Perfumery, food, beverage and flavour manufacturers use this line, and nutraceutical, pharmaceutical and cosmetic active-ingredient buyers draw on the same GC documentation for consistent supply. Every plant is built in electropolished SS 316L with CIP cleaning to GMP hygienic design.

Which plant part or feed form does the coriander seed plant process?

The candidate feedstock is coriander seeds (seeds). The target extract is phenolics and linalool-rich oil.

Which extraction technologies are suitable for coriander seeds?

This feedstock has 5 candidate technologies: Counter-Current Extraction (CCE), Supercritical CO₂ Extraction (SCFE), Ultrasound-Assisted Extraction (UAE), Hybrid Extraction and Microwave-Assisted Extraction (MAE). See the related pages on counter-current extraction, supercritical CO₂ extraction, ultrasound-assisted extraction, hybrid extraction and microwave-assisted extraction. These are screening candidates, not guarantees of yield, purity or recovery; the route is confirmed through process development and pilot validation. In Mechotech's technology screening these candidates are ranked directionally — relevant: Counter-Current Extraction for phenolics (rank 36 of 100), Supercritical CO₂ Extraction for linalool-rich oil (rank 53 of 100), Ultrasound-Assisted Extraction for phenolics (rank 36 of 100), Hybrid Extraction for phenolics (rank 37 of 100), Microwave-Assisted Extraction for phenolics (rank 36 of 100). Ranks are directional screening priorities at method-family level, not measured yield, ROI or plant guarantees.

Why do the candidate technologies target phenolics and linalool-rich oil when the specification on this page is linalool by GC 60–75%?

In Mechotech's technology screening the candidate routes are assessed against different targets: the counter-current, ultrasound, hybrid and microwave routes with phenolics as the target and the supercritical CO₂ route with linalool-rich oil as the target. The linalool by GC 60–75% specification on this page is the catalogue specification for this product; which target and grade apply is confirmed during process development and pilot validation.

How does the coriander seed extraction process work?

Each route follows the same outline: prepare coriander seeds, extract phenolics and linalool-rich oil using the technology-specific step, separate and clarify the extract, concentrate it, and recover, standardise and dry. The process tabs above show the steps for each listed technology.

What equipment does the coriander seed extraction plant include?

The equipment follows the selected route and includes seed cleaning and destoning system; cracking mill / hammer mill (controlled size reduction); stainless-steel jacketed solvent extraction vessels (SS 316L); solvent storage tanks; solvent transfer pumps; plate heat exchangers; plate-and-frame filter press / pressure leaf filter; cartridge polish filters. The full list is shown under Major Plant Equipment.

Which related Mechotech extraction pages cover the same material or target?

Coriander seed CO₂ oil is covered on the Coriander Seed Oil (CO₂) page, and coriander seed distillation on the Coriander (seed distillation) page. Coriander oleoresin sits within Mechotech's wider range of spices oleoresin extraction plants.

What is the typical cost and delivery timeline for a Coriander oleoresin plant?

Cost depends on the target linalool grade within the listed range, the evaporator and packing configuration, capacity and whether a carrier-based powder line is included. Mechotech provides a detailed techno-commercial proposal after understanding your target Linalool by GC grade and throughput; typical turnkey delivery — design, fabrication, installation and commissioning — runs a few months from order, depending on scope.
