Plant peptide extraction membrane separation technology

Peptides are important physiological regulators in the human body, which can comprehensively regulate human physiological functions, enhance and exert human physiological activity, and have important biological functions. Peptides are crucial for human cellular activity, functional activity, and the existence of life.

Biological enzymatic hydrolysis is the main technical means for producing peptide products. For example, in the production of marine biological peptides, soybean, corn and other plant peptides, the raw materials are processed by enzymatic hydrolysis and filtered using traditional centrifugation and other techniques. However, the clarification effect and yield cannot achieve the expected results, and the wastewater is large and the operation is cumbersome. Compared with traditional filtration techniques, membrane separation technology has unparalleled advantages.

Shengchuan, with years of project experience and technical strength in the field of peptides, uses professional enzymatic peptide separation and extraction technology to separate peptides of different molecular weights using molecular cutting membranes in the production process of plant peptides. After separation and purification, the product does not undergo any qualitative changes during the separation and purification process; The purified product is subjected to decolorization process to remove chromaticity; Reuse membrane separation technology for desalination, ash removal, and concentration, while ensuring that the original properties of the substance remain unchanged; Solved the problem of high impurities and dark colors, and improved the overall product quality by one level.

Process flow of plant peptide separation and extraction technology:

Plant peptides → tissue fragmentation pretreatment → multi-step enzymatic hydrolysis → centrifugal filtration → ultrafiltration separation and purification → decolorization → membrane desalination and concentration → evaporation powder spraying → packaging

Characteristics of plant peptide membrane separation and extraction technology:

1. Membrane filtration is fast and stable, with high yield of active ingredients.

2. The clarification effect of the filtrate is good, which reduces the difficulty of subsequent processing and greatly improves the quality of the product.

3. Membrane cleaning has the characteristics of strong regeneration ability, long service life, and low operating costs.

4. The device has a high degree of automation, easy operation, and clean production site.

5. Cooperating with the nanofiltration membrane desalination section in the later stage, a membrane integrated extraction system is formed, greatly reducing the ash content of the product.
