Fish peptone is a fine light yellow to yellowish powder derived from fresh fish bones through advanced biological extraction technology. Our production process as a leading China supplier involves meticulous raw material cleaning, enzymatic hydrolysis, centrifugal separation, decolorization, purification, vacuum concentration, and spray drying. This efficient method breaks down fish bone protein into small peptides and free amino acids, while preserving water-soluble active substances for high purity and excellent solubility.

As a premium organic nitrogen source, fish peptone boasts a rich profile of small molecular peptides, free amino acids, trace elements, and growth factors. It is quickly absorbed and utilized by microorganisms, promoting cell proliferation, protein synthesis, and enhancing metabolic enzyme activity. This significantly improves strain growth density and fermentation stability, making it an essential component for various applications.

Fish peptone is widely utilized in microbial fermentation, vaccine production, and the creation of biological products and industrial fermentation processes. When combined with yeast extract, malt extract, and other medium components, it optimizes nutrient matching and enhances the expression of target products. This versatility makes it a popular choice in preparing complex media for scientific research and industrial production in numerous factories worldwide.
