Many active substances in the human body exist in the form of peptides, and their importance in the fields of human biology and medicine cannot be replaced by other substances. Peptides are intermediate products of protein hydrolysis, including bioactive peptides and synthetic peptides. In terms of its types, it includes:

1. Cytokine mimetic peptides. If further clinical research can effectively apply it to the field of medicine;

2. Antibacterial active peptides. Mainly extracted from animals, it has a certain antibacterial effect;

3. Peptides used for cardiovascular diseases. The active peptides extracted from soybeans through technological means can be directly absorbed through the small intestine, effectively preventing and treating thrombosis, hypertension, and hyperlipidemia. They can also delay aging to a certain extent and improve the body's anti-tumor ability. Plant derived peptides can also be isolated from plants such as ginseng, tea, and ginkgo leaves to produce small peptide components that can be used for cardiovascular diseases;

4. Multipurpose medicinal peptides. Synthetic peptides have the effects of regenerating wound blood vessels and inhibiting inflammatory reactions;

5. Diagnostic peptides. The clinical application of antigen detection for viruses mostly uses peptide antigens isolated and analyzed from the natural proteins of the corresponding pathogens.

The application of peptides cannot do without efficient separation and treatment processes. The better the concentration and separation effect, the higher the practical value of peptides. To separate and purify active short peptide products with concentrated relative molecular weight and high purity, membrane separation technology with good separation performance and continuous processing may be an ideal method.

Membrane separation equipment uses physical technology to filter solutions, achieving effective separation between liquids and substances, and achieving the goal of complete filtration. Ultrafiltration membrane separation equipment, with its green and efficient separation characteristics, is increasingly widely used in peptide extraction and plays an important role in industrial structure adjustment, traditional industry transformation, and energy conservation and emission reduction.

The Literide membrane separation equipment is used for peptide extraction without any additional additives, maintaining the purity and quality of peptides. The membrane separation equipment has mature technology, compact structure, and is made of sanitary grade stainless steel. It operates in a fully enclosed pipeline and meets FDA food regulatory requirements.
