Executive Summary
A manufacturer of natural food ingredients required a fully automated, GMP-oriented Paprika Oleoresin Extraction Plant to manufacture premium-quality Paprika Oleoresin, Natural Paprika Colour, and Carotenoid-Rich Extracts for the global food, beverage, pharmaceutical, nutraceutical, and cosmetic industries.
The customer's objective was to maximise oleoresin yield, preserve natural carotenoid pigments, minimise solvent consumption, and consistently achieve high ASTA colour values suitable for export markets.
Mechotech successfully designed, engineered, manufactured, installed, and commissioned a Paprika Oleoresin Extraction Plant featuring advanced solvent extraction, precision filtration, vacuum concentration, high-efficiency solvent recovery, polishing filtration, product standardisation, and intelligent PLC-SCADA automation.
Customer Background
The customer supplies natural paprika extracts to food ingredient manufacturers, snack food industries, sauce & condiment manufacturers, meat processing companies, dairy product manufacturers, beverage companies, cosmetic manufacturers, and international ingredient exporters. Growing consumer demand for clean-label natural food colours prompted the customer to invest in a modern, energy-efficient processing facility.
Customer Challenges
The customer experienced several production limitations:
- Low oleoresin recovery
- Loss of carotenoid pigments
- Oxidation during processing
- High solvent consumption
- Variable ASTA colour values
- High energy costs
- Manual batch inconsistencies
- Limited export-grade production
- Difficulty complying with international food safety standards
Project Objectives
Mechotech was commissioned to deliver a turnkey plant capable of:
- Processing 20 MT/day of Paprika Pods
- Producing premium Paprika Oleoresin
- Preserving natural carotenoids
- Achieving high ASTA colour values
- Recovering extraction solvent for reuse
- Reducing production costs
- Meeting GMP, HACCP, and international export standards
- Supporting future expansion

Process Flow
Process Description
Raw Material Preparation
Premium-quality paprika pods are cleaned, destemmed where required, dried, and ground to the optimum particle size for efficient extraction while protecting sensitive carotenoid pigments.
Solvent Extraction
Ground paprika is processed in stainless steel extraction vessels using food-grade solvents under carefully controlled operating conditions.
The extraction process ensures:
- High oleoresin yield
- Reduced solvent consumption
- Uniform product quality
Primary Filtration
Pressure filtration removes suspended solids while retaining valuable pigments, oils, and flavour compounds.
Vacuum Concentration
Clarified extract is concentrated under vacuum using multi-effect evaporators operating at low temperatures.
Advantages include:
- Protection of carotenoids
- Minimal oxidation
- Reduced steam consumption
- Improved product stability
- Enhanced colour preservation
Solvent Recovery
Mechotech's closed-loop solvent recovery system efficiently recovers extraction solvent through multi-stage evaporation and condensation.
Recovered solvent is:
- Condensed
- Purified
- Stored
- Reused
Solvent is recovered for reuse.
Polishing Filtration
Final polishing filtration removes trace impurities and improves clarity while maintaining the natural colour profile.
Product Standardisation
Paprika oleoresin is standardised according to customer specifications for:
- ASTA Colour Value
- Carotenoid Content
- Capsanthin Content
- Viscosity
- Moisture
- Residual Solvent Limits
