Executive Summary
A global manufacturer of natural food ingredients and pharmaceutical intermediates required a fully integrated, GMP-oriented extraction facility for producing Capsicum Oleoresin and High-Purity Capsaicin from premium red chilli peppers (Capsicum annuum and Capsicum frutescens). The objective was to manufacture standardised products for food seasoning, pharmaceutical formulations, self-defence products, veterinary applications, and industrial specialty chemicals.
Mechotech designed, manufactured, installed, and commissioned a Capsaicin Extraction Plant featuring advanced solvent extraction, oleoresin separation, capsaicin purification, crystallisation, solvent recovery, vacuum drying, and PLC-SCADA automation.
Customer Background
The customer supplies Capsaicin and Capsicum Oleoresin to spice ingredient manufacturers, food processing industries, pharmaceutical companies, nutraceutical manufacturers, veterinary medicine producers, specialty chemical manufacturers, and international ingredient distributors. The increasing global demand for natural capsaicinoids required expansion into a highly automated manufacturing facility with pharmaceutical-grade process control.
Customer Challenges
Prior to implementing the new plant, the customer experienced:
- Low Capsaicin recovery
- High solvent consumption
- Inconsistent pungency levels
- Poor colour retention
- Long extraction cycles
- High manpower requirements
- Variable product quality
- Difficulty meeting international export specifications
- Limited production capacity
Project Objectives
Mechotech was commissioned to deliver a turnkey facility capable of:
- Processing 15 MT/day of dried red chilli
- Producing premium Capsicum Oleoresin
- Producing high-purity Capsaicin
- Maximising capsaicinoid recovery
- Closed-loop solvent recovery
- Reducing operating costs
- Documentation to support the customer's quality and regulatory qualification
- Supporting future expansion

Process Flow
Process Description
Raw Material Preparation
Premium dried chillies are cleaned, destemmed if required, and milled under controlled conditions to achieve the optimum particle size for efficient extraction.
Solvent Extraction
Prepared chilli powder is transferred into stainless steel extraction vessels where food-grade solvents selectively extract capsaicinoids, carotenoids, and other valuable compounds.
The optimised extraction process provides:
- High Capsaicin recovery
- Better colour retention
- Reduced solvent usage
- Uniform extraction efficiency
Primary Filtration
The extract passes through pressure filtration systems that remove suspended solids while preserving valuable oleoresin components.
Vacuum Concentration
The clarified extract is concentrated using low-temperature vacuum evaporation.
Benefits include:
- Preservation of colour
- Protection of heat-sensitive compounds
- Lower steam consumption
- Improved product stability
Oleoresin Separation
Advanced separation systems isolate high-quality Capsicum Oleoresin with controlled colour and pungency specifications suitable for food applications.
Purification
The concentrated extract undergoes specialised purification to remove waxes, pigments, and unwanted impurities before Capsaicin isolation.
Capsaicin Crystallisation
Controlled crystallisation produces pharmaceutical-grade Capsaicin crystals with excellent purity and consistency.
Process parameters monitored include:
- Temperature profile
- Solvent composition
- Crystal growth rate
- Agitation speed
- Purity optimisation
Centrifugation
Industrial centrifuges efficiently separate Capsaicin crystals from the mother liquor while minimising product losses.
Vacuum Drying
Vacuum drying produces stable Capsaicin crystals with:
- Low residual moisture
- High purity
- Long shelf life
Blending & Standardisation
Products are standardised according to customer specifications for capsaicinoid concentration, colour value, and pungency before packaging.
