Fish peptone, a high-quality organic nitrogen source, is produced from fresh fish bones using advanced biological extraction technology. This light yellow to yellowish fine powder results from a meticulous production process that includes cleaning, enzymatic hydrolysis, centrifugal separation, decolorization, purification, vacuum concentration, and spray drying. These methods effectively break down fish bone protein into small peptides and free amino acids while preserving water-soluble active substances, ensuring a product of high purity and excellent solubility, Rich in small molecular peptides, free amino acids, trace elements, and growth factors, fish peptone is rapidly absorbed and utilized by microorganisms. This accelerates cell proliferation, enhances protein synthesis and metabolic enzyme activity, and significantly boosts strain growth density and fermentation stability, As one of the leading suppliers and manufacturers in China, our fish peptone is widely utilized in microbial fermentation, vaccine production, biological products, and industrial fermentation. When combined with other medium components such as yeast extract and malt extract, it optimizes nutrient matching and enhances the expression of target products, making it ideal for developing various complex media for scientific research and industrial applications.
