Executive Summary
A leading Middle Eastern food ingredient manufacturer required a fully automated, GMP-compliant Pistachio Protein Isolate (PPI) Manufacturing Plant capable of producing premium Pistachio Protein Isolate (88–92% Protein), Pistachio Protein Concentrate, Cold-Pressed Pistachio Oil, Defatted Pistachio Flour, and Pistachio Fiber for sports nutrition, dairy alternatives, protein beverages, bakery products, confectionery, nutraceuticals, and pharmaceutical applications.
The customer required a turnkey manufacturing facility capable of maximizing protein recovery from cold-defatted pistachio meal, preserving the nutritional quality of premium pistachio oil, minimizing oxidation, reducing water and energy consumption, and consistently producing export-quality ingredients complying with GMP, WHO-GMP, HACCP, ISO 22000, FSSC 22000, BRCGS, USFDA, and international food safety standards.
MECH O TECH LLP successfully designed, engineered, manufactured, supplied, installed, and commissioned a 80 TPD Pistachio Protein Manufacturing Plant integrating advanced nut cleaning, shell separation, kernel grading, cold pressing, protein extraction, membrane filtration, vacuum concentration, spray drying, PLC-SCADA automation, and fully automated CIP systems.
The facility consistently produces premium pistachio protein ingredients with excellent digestibility, pleasant nutty flavor, superior emulsification properties, and exceptional global market acceptance.

Low-temperature mechanical pressing preserves the nutritional value and flavor of pistachio oil while producing protein-rich meal.
Advantages include:
- Premium edible oil recovery
- Low-temperature processing
- Reduced oxidation
- Higher protein concentration
- Improved product quality
- Better profitability
Protein Extraction
Protein is extracted under optimized conditions to maximize recovery while preserving native protein functionality.
Benefits include:
- High protein recovery
- Excellent digestibility
- Superior emulsification
- Pleasant natural flavor
- Excellent dispersibility
- Consistent product quality
Membrane Filtration
Advanced ultrafiltration and diafiltration systems remove:
- Soluble carbohydrates
- Minerals
- Low molecular weight compounds
- Residual oil traces
Benefits include:
- Protein purity up to 92%
