Executive Summary
A leading global starch manufacturer sought a fully automated, GMP-compliant Potato Protein Isolate (PPI) Manufacturing Plant to recover high-value protein from Potato Fruit Juice (PFJ) generated during potato starch production. The objective was to convert a low-value process stream into premium Potato Protein Isolate (90–95% Protein), functional protein concentrates, and specialty protein ingredients for food, nutraceutical, sports nutrition, pet food, aquaculture, and pharmaceutical applications.
The customer required a turnkey manufacturing facility capable of maximizing protein recovery while preserving amino acid integrity, minimizing thermal degradation, reducing wastewater load, and consistently producing export-quality ingredients in compliance 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 250 TPD Potato Protein Manufacturing Plant integrating advanced protein coagulation, decanter centrifugation, membrane filtration, vacuum concentration, spray drying, PLC-SCADA automation, and fully automated CIP systems.
The facility consistently produces premium potato protein with excellent digestibility, high lysine content, superior emulsification properties, and excellent international market acceptance.
