Executive Summary
A leading European plant-based ingredient manufacturer required a fully automated, GMP-compliant Lupin Protein Isolate (LPI) Manufacturing Plant capable of producing premium Lupin Protein Isolate (90–93% Protein), Lupin Protein Concentrate, Food-Grade Lupin Fiber, and Lupin Starch for sports nutrition, meat alternatives, dairy substitutes, bakery products, gluten-free foods, nutraceuticals, and pharmaceutical applications.
The customer required a turnkey manufacturing facility capable of maximizing protein recovery from sweet lupin seeds, removing naturally occurring bitter alkaloids, preserving protein functionality, reducing water and energy consumption, and consistently producing export-quality ingredients compliant 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 180 TPD Lupin Protein Manufacturing Plant integrating advanced seed cleaning, dehulling, debittering, wet milling, alkaline protein extraction, membrane filtration, vacuum concentration, spray drying, PLC-SCADA automation, and fully automated CIP systems.
The facility consistently produces premium lupin protein ingredients with excellent emulsification, foaming, gelation, and water-binding properties for demanding food applications.
