Application of Membrane Separation Technology in Collagen Extraction and Purification | High-Efficiency Separation · Activity Preservation · Energy Conservation

Collagen, as a functional protein, is widely used in the beauty and healthcare industries. Traditional extraction processes suffer from high energy consumption, significant activity loss, and low product purity. Leveraging years of experience in plant extraction and integrating ceramic membrane and polymeric membrane technologies, Shandong Qisheng Membrane Separation has launched a dedicated membrane-based extraction system for collagen, achieving high-efficiency separation, low-temperature concentration, and simultaneous desalination and deodorization, comprehensively enhancing product quality and production efficiency.

Process Flow

Enzymatic Hydrolysate → Fine Filtration → Ultrafiltration Impurity Removal → Nanofiltration Concentration → Spray Drying

Ultrafiltration Impurity Removal: Effectively removes macromolecular proteins, tannins, and pigments, improving product purity and taste.

Nanofiltration Concentration: Simultaneously achieves concentration and desalination, reduces undesirable bitterness and pesticide residues, while preserving the bioactivity of collagen.

Technical Advantages

High Efficiency and Energy Savings, Lower Costs – Membrane concentration consumes only 30% of the energy required by traditional thermal concentration, significantly reducing operational costs.

Quality Improvement, Better Taste – Precise impurity removal at the front end effectively enhances collagen purity and taste, substantially strengthening product competitiveness.

Desalination, Deodorization, and Activity Preservation – Removes inorganic salts and undesirable odors during concentration. The entire process operates at ambient temperatures, ensuring that protein bioactivity remains intact.

Anti-Fouling Design for Stable Operation – Specially designed flow channels effectively mitigate membrane fouling, maintaining stable system flux and extending service life.

Shortened Production Cycle and Clean Production – The integrated process significantly shortens the production cycle. Membrane permeate water can be reused, enabling resource recycling and environmental emission reduction.
