Whey Protein Concentration & Desalination By Membrane Separation
Membrane separation technology enables room‑temperature concentration and desalination for whey protein liquid. After ultrafiltration treatment, feed solution is separated into milky‑white protein‑rich retentate (concentrate) and clear permeate (filtrate). Compared with conventional thermal evaporation, this process avoids protein denaturation, reduces energy consumption and wastewater output. It is also suitable for soybean peptide and other plant protein purification. Pilot lab testing is offered to confirm processing performance for industrial scale‑up.
Soy Protein Peptide Solution Purification by Membrane Separation Technology
Crude soy protein peptide hydrolysate features dark color, high turbidity and numerous macromolecular impurities, which downgrade final peptide product quality. Membrane separation technology including ultrafiltration and nanofiltration offers a physical, non‑thermal purification solution. Ultrafiltration removes macromolecular proteins, colloids and pigments to obtain clear peptide filtrate. Subsequent nanofiltration achieves further desalination and concentration. This article introduces process selection, practical effect and core advantages of membrane filtration for soy peptide clarification, providing references for industrial‑scale plant polypeptide production.
Ultrafiltration vs Ceramic Membrane: How to Choose for Plant‑based Extract Filtration
When clarifying plant‑based extracts, manufacturers often struggle to decide between polymeric ultrafiltration and ceramic membranes. This article compares their investment cost, chemical resistance, service life and operating limits. It offers practical selection principles based on feed liquid solids, viscosity, pH‑temperature conditions and project budget. Buyers should not only focus on upfront price, but also evaluate long‑term running expenses. Pilot tests with real feed material are suggested to confirm actual flux and product recovery. Even high‑performance ceramic membranes require proper pretreatment to avoid severe fouling.
