Introduction
The food and beverage industry increasingly relies on membrane filtration technologies to enhance product quality, improve yield, and reduce waste. Among these, ultrafiltration (UF) membranes play a pivotal role in protein and whey processing, offering superior selectivity, energy efficiency, and scalability compared to traditional methods such as evaporation or chemical precipitation.
As a leading Chinese manufacturer of ultrafiltration membranes, we specialize in producing high-performance, cost-effective UF membranes tailored for dairy, plant-based protein, and functional food applications. Our in-house production ensures competitive pricing, rapid delivery, and customizable solutions, making us the preferred partner for food processors worldwide.

Key Applications of UF Membranes in Protein & Whey Processing
1. Dairy Protein Standardization & Whey Fractionation
Ultrafiltration is extensively used in dairy processing to:
Standardize milk protein content for cheese, yogurt, and infant formula production.
Concentrate whey proteins (β-lactoglobulin, α-lactalbumin) from cheese byproducts, increasing protein content up to 80% or higher.
Remove lactose and minerals, improving whey protein isolate (WPI) purity for sports nutrition and functional foods.
Studies show that optimized UF parameters (0.15 MPa, 35°C, 6x concentration factor) can achieve 58.19% IgG recovery in bovine colostrum whey, demonstrating high efficiency in bioactive compound enrichment
2. Plant-Based Protein Isolation
Beyond dairy, UF membranes are crucial for:
Soybean whey protein recovery, where ceramic UF membranes (5 nm pore size) achieve 73.3% protein retention at pH 6.
Pea, rice, and other plant protein concentrates, ensuring high yield and minimal thermal degradation.
3. Oligosaccharide Separation from Goat Milk
UF enables the extraction of prebiotic oligosaccharides from goat milk—similar to human milk—while removing proteins for infant formula applications. Research confirms >99% oligosaccharide recovery using 50 kDa ceramic membranes
