Coriander Extraction Plant
Coriander Extraction Plant
Coriander (Coriandrum sativum) seed oleoresin is a valued flavouring ingredient containing linalool (60%–70%) and fixed fatty acids. Mechotech's coriander extraction plants deliver consistent, food-grade oleoresin and optionally linalool-standardized essential oil fractions for the food, fragrance, and pharmaceutical markets.
Mechotech designs coriander seed extraction plants using food-grade solvent extraction to produce oleoresin with authentic coriander flavour profile. The plant features vacuum evaporation for low-temperature solvent recovery, multi-stage filtration, and GC standardization to ensure each batch meets the customer's volatile oil specification. Optional combination with steam distillation gives integrated oleoresin + essential oil production.
Manufacturing Process
Seed Grinding
Coriander seeds are cleaned, inspected, and ground to 20–40 mesh. Pre-extraction volatile oil content is measured to predict oleoresin yield.
Solvent Extraction
Ground seeds are extracted with food-grade ethanol or acetone in percolation vessels with multiple solvent passes to maximize linalool and oleoresin recovery.
Filtration
The coriander miscella is filtered through multi-stage filtration including sparkler and polishing filters to remove all particulate and colour bodies.
Evaporation
Filtered miscella is concentrated in a falling-film evaporator under vacuum at 50–60°C, producing a pale yellow to pale orange viscous oleoresin.
Standardization
Oleoresin is tested for volatile oil content, linalool percentage, and fixed oil content. Batches are adjusted to meet customer specification before packing.
Filling & Packing
Standardized oleoresin is filled into lacquer-lined food-grade tins or bulk drums under nitrogen blanket to preserve the delicate linalool aroma during storage.
Applications
- Food flavouring (sausage, pickle, curry powder)
- Beverage and distilled spirit flavouring
- Pharmaceutical digestive and carminative formulations
- Fragrance compounding (citrus-floral notes)
- Bakery and confectionery flavour applications
- Ayurvedic digestive preparations
- Cosmetic and soap fragrance
- Tobacco flavouring applications
Key Features
Linalool Preservation
Low-temperature vacuum evaporation below 60°C prevents linalool evaporation and thermal transformation, preserving the characteristic delicate coriander aroma.
High Volatile Oil Recovery
Optimized extraction sequence achieves 90%+ volatile oil recovery from the seed matrix, maximizing the value of raw material per batch.
Dual-Mode Processing
Optional steam distillation pre-step removes essential oil fraction before solvent extraction of the fixed-oil rich oleoresin from the same seed batch.
Food-Grade Compliance
Complete food safety compliance with FSSAI, FDA 21 CFR Part 182, and EU Regulation 1334/2008 for spice oleoresin in food manufacturing.
Multi-Spice Platform
The same plant processes cumin, fennel, caraway, coriander, and other umbelliferous spices with parameter adjustments, maximizing equipment utilization.
